            <p> Subgenus  Dialictus Robertson, 1902</p>
            <p> Dialictus Robertson, 1902: 48. Type species: Halictus anomalus Robertson 1892 , by original designation and monotypy. </p>
            <p> Lasioglossum (Dialictus) – sensu Gibbs (2018b). </p>
            <p>Diagnosis</p>
            <p> Lasioglossum (Dialictus) are small bees (body length 3.1–8.1 mm) whose diagnosis on a global scale is somewhat problematic due to known exceptions to diagnostic characters. But on a regional scale, L. (  Dialictus ) can be reliably diagnosed from other  Halictidae occurring on the Yucatán Peninsula by the combination of head and mesosoma dark (not brilliant) metallic blue, green, or golden, sometimes with red-brassy reflections; metasoma black, brown, or red; second and third fore wing submarginal crossveins weakened in the female; T1 with well-developed setose fan in the female; inner metatibial spur of the female pectinate; and male clypeus apical margin black (not yellow). </p>

            <p> Lasioglossum (Dialictus) yucatanense Landaverde-González sp. nov.</p>
            <p>urn:lsid:zoobank.org:act: F9897B79-0567-4EAB-802A-1E0C1B4D65E1</p>
            <p>Figs 1, 5A–B, 6A, 7–8, 30B, 36A</p>
            <p>Diagnosis</p>
            <p> Females of  L. yucatanense sp. nov. can be recognized by the vertex and mesoscutum having very short, sparse pubescence, as if shaved (most noticeable in lateral view where most setae are separated by half or more their length); mesosoma entirely dulled by strong microsculpture; mesoscutum usually densely punctate laterad of parapsidal lines (i &lt;1 pd) and sometimes partially shiny (especially posteromedially); mesepisternum strongly imbricate to finely rugulose with indistinct punctures at least in dorsal portion; tegula enlarged (reaching posterior margin of mesoscutum in dorsal view; tegula width/ITS&gt; 0.23) and distinctly, densely punctate on lateral margins (i &lt;1 pd), becoming more sparsely punctate medially (i ≥ 1 pd), sometimes densely punctate medially (i &lt;1 pd); metapostnotum with fine rugae extending onto propodeum dorsolateral slope; discs of T1–T2 with very fine, minute punctures, often hardly visible; and T2 and usually T3 apical impressed areas glabrous and impunctate. Males can be recognized by the same characters as females, except that the mesepisternum is shiny and distinctly and densely punctate (i &lt;1 pd). </p>
            <p>Differential diagnosis</p>
            <p> Both sexes of  L. yucatanense sp. nov. are most similar to  Lasioglossum paxtoni sp. nov. and  L. aureoviride sp. nov. and some members of the  L. stictaspis species complex in the Yucatán Peninsula. They are also similar to the Nearctic species  L. perparvum , which does not co-occur with  L. yucatanense , and some undescribed species related to  L. perparvum which may co-occur with  L. yucatanense at the limits of its range. Both sexes of  L. paxtoni have the tegula more finely and sparsely, sometimes inconspicuously punctate (i = 1–2 pd on lateral margins), mesonotum and mesoscutum shiny, mesoscutum finely and sparsely punctate (i = 1–3 pd) becoming slightly denser laterad of parapsidal lines (i = 1–2 pd); females also have the mesepisternum shiny, granular and finely, moderately densely punctate.  Lasioglossum aureoviride females have the mesoscutum weakly tessellate and sparsely punctate between parapsidal lines (i = 1–3 pd), T2–T3 apical impressed areas evenly covered with minute punctures and fine setae, head and mesosoma metallic dark turquoise-green with golden reflections on mesoscutum, and mesepisternum very densely punctate (i &lt;0.5 pd). Both sexes of the  L. stictaspis species complex have the mesoscutum with longer and denser pubescence (in lateral view all setae separated by less than half their length); females also have the mesepisternum usually imbricate and deeply, moderately densely punctate (i ≤ 1.5 pd) with distinct interspaces and T2–T3 apical impressed areas usually with minute punctures or setae; males also usually have the mesepisternum more sparsely punctate (i = 1–2 pd). Females of  L. perparvum have the mesepisternum distinctly punctate and T2–T3 apical impressed areas with minute punctures; males have T1–T2 with deep and distinct punctures often extending across premarginal line onto apical rim. Other undescribed species may have the tegula much larger (exceeding posterior margin of mesoscutum in dorsal view) and/or entirely densely punctate (i &lt;1 pd); propodeum dorsolateral slope smooth without metapostnotal rugae; and/or mesepisternum shiny and distinctly punctate. </p>
            <p>Etymology</p>
            <p>The specific epithet refers to the Yucatán Peninsula region, Mexico where the species was discovered. The name was proposed by Manfred Stark who won a photo competition to name a species of bee at an event at the ZMH.</p>

            <p> Thirty sequences available, two haplotypes (BOLD process IDs: LDSPS002-15 to LDSPS008-15, LDSPS010-15 to LDSPS028-15 (haplotype 1); DLII504-07, DLIII127-18, DLIII137-19, DLIII138-19 (haplotype 2). The holotype GenBank accession number: KU574888. BOLD process ID: LDSPS009-15. Haplotype 1 is morphologically and genetically similar to haplotype 2 with a large number of sequences available (consistent with the relative abundance of specimens of  L. yucatanense sp. nov. ). The sequences are highly variable (maximum intraspecific p-distance between haplotypes 3.53%; within haplotype 1 intraspecific p-distance 0.54%; minimum interspecific p-distance (to  L. paxtoni sp. nov. ) 2.89%). Two reasons that may influence the high intraspecific variation are the existence of cryptic species throughout the distribution of these taxa and problems in the quality of the sequence data for the Yucatán specimens. </p>

            <p>Distribution</p>
            <p>Widely dispersed throughout the eastern lowlands of Mexico from Tamaulipas to Yucatán and Chiapas and in northwestern Guatemala. Two outliers from Jalisco and Guerrero are morphologically</p>
            <p>indistinguishable from the eastern specimens; it is unclear whether these represent long-range dispersal events, a natural range extension, or a cryptic species.</p>
            <p>Remarks</p>
            <p> Very common. Specimens of both DNA barcode haplotypes are morphologically indistinguishable, but geographically separate. All haplotype 1 sequences are from Yucatán while haplotype 2 is from Puebla, Veracruz, and Chiapas. It is possible that these represent cryptic species; however, the geographic separation disappears when considering all available specimens (with barcodes or not). Yet, the variation between haplotypes could be reinforced, mainly when considering genetic variation, following the findings from other species of bees and insects in the region (Landaverde-González et al. 2020; Urueña et al. 2022). Thus, in order to be conservative, it is inadvisable to consider a two-species hypothesis at this time. This species is a member of the  L. gemmatum species complex and corresponds to mOTU 1 in Landaverde-González et al. (2017a). </p>

            <p> Lasioglossum (Dialictus) paxtoni Landaverde-González sp. nov.</p>
            <p>urn:lsid:zoobank.org:act: 8AB32A78-9274-49AE-B9CA-3D2BF1A925BE</p>
            <p>Figs 5C–D, 6B, 9–10, 28A, 29A, 30A</p>
            <p>Diagnosis</p>
            <p> Females of  L. paxtoni sp. nov. can be recognised by having the vertex and mesoscutum with very short, sparse pubescence as if shaved (most noticeable in lateral view where most setae are separated by half or more their length); tegula enlarged (reaching posterior margin of mesoscutum in dorsal view; tegula width/ITS 0.21–0.22) and lateral margin with shallow, minute, and sparse punctures (i = 1–2d) no larger than mesoscutum punctures (sometimes inconspicuous and tegula nearly impunctate); mesoscutum shiny, finely and sparsely punctate (i = 1–3 pd), becoming slightly denser laterad of parapsidal lines (i = 1–2 pd), and with distinct red–brassy reflections medially; mesepisternum shiny, granular and finely, moderately densely punctate (i = 1–1.5 pd); metapostnotum with fine rugae extending onto propodeum dorsolateral slope; discs of T1–T2 with very fine, minute punctures, often hardly visible; and T2 and usually T3 apical impressed areas glabrous and impunctate. Males can be recognized by the same characters, except that the mesoscutum color is less red and more brassy, and the mesepisternum is more densely punctate (i &lt;1 pd), the mesoscutum has sparse plumose setae 0.5–1 OD long (most setae separated by half their length or more in lateral view, especially in posterior half). </p>
            <p>Differential diagnosis</p>
            <p> Both sexes of  L. paxtoni sp. nov. are most similar to  L. yucatanense sp. nov. ,  L. (D.) aureoviride sp. nov. , specimens of the  Lasioglossum stictaspis species complex, the Nearctic species  L. perparvum , and some undescribed species related to  L. perparvum which are not known to co-occur with  L. paxtoni . See the differential diagnosis for  L. yucatanense for characters separating these species.  Lasioglossum (D.) aureoviride has the mesoscutum weakly tessellate and sparsely punctate between the parapsidal lines (i = 1–3 pd) and with dense erect setae ~1 OD long (all setae separated by less than half their length in lateral view); T2–T3 apical rims evenly covered with fine setae and/or punctures; mesoscutum with dense erect setae ~1 OD long and subappressed setae 0.25–0.5 OD long; mesepisternum imbricate and very densely punctate (i &lt;0.5 pd). </p>
            <p> Specimens of  Lasioglossum stictaspis species complex have the mesepisternum imbricate and deeply, moderately densely punctate (i ≤ 1.5 pd) with distinct interspaces, T2–T3 apical rims evenly covered with fine setae and/or punctures. Females of  L. perparvum have the scutum olive green with no red reflections, tarsi dark brown, scutum tessellate, mesepisternum tessellate with indistinct punctures, and </p>
            <p>T2–T3 with extensive basolateral fine tomentum covering about half length of segment laterally and apical impressed areas minutely punctate with fine setae associated with punctation.</p>
            <p> One undescribed species from western Veracruz labeled as L. sp. mex9 on BOLD is especially similar to  L. paxtoni sp. nov. , but lacks copper-red reflections on the mesoscutum and the tegula is more deeply and distinctly (but still sparsely) punctate. This species is apparently restricted to high elevations in the Sierra Madre Oriental mountains, in contrast to  L. paxtoni which is restricted to the Yucatán Peninsula and northern Chiapas. </p>
            <p>Etymology</p>
            <p>The specific epithet is in dedication to Prof Robert Paxton, the PhD advisor of PLG and JQE.</p>

            <p> Five sequences available (BOLD process IDs: LDSPS029-15 to LDSPS033-15). The attribution of these sequences to  L. paxtoni sp. nov. is based on their genetic similarity to the undescribed L. sp. mex9, which is morphologically similar to the description of  L. paxtoni (unfortunately the specimen originally designated as a holotype was destroyed), and the small number of available sequences (consistent with the low relative abundance of  L. paxtoni ). The sequences are variable and distinguished from those of other species (maximum intraspecific p-distance 0.82%; minimum interspecific p-distance (to  L. yucatanense sp. nov. ) 2.89%). </p>

            <p> Lasioglossum stictaspis species complex </p>
            <p>Figs 6C, 11–12, 22C, 31A</p>
            <p> Ten specimens and six DNA barcode sequences were examined from the Yucatán Peninsula which belong to a complex of species related to  L. stictaspis (Sandhouse, 1923) . Morphological variation suggests that this complex may include up to 5–6 cryptic species, but overlapping geographic ranges and COI haplotypes preclude delimitation of these species. Further revision, including more robust genetic data beyond DNA barcodes and across a large geographic area, is needed. The Yucatán specimens appear to be distinct from the nominal  L. stictaspis , but separating them from  L. cupreicollis (Friese, 1917) and other undescribed morphospecies is difficult and beyond the scope of this study. Here we diagnose briefly the Yucatán morphospecies in the  L. stictaspis species complex from other species on the Yucatán Peninsula. </p>
            <p>Diagnosis</p>
            <p> Females of the  L. stictaspis species complex in the Yucatán Peninsula can be recognised by the diagnostic combination of tegula greatly enlarged (reaching posterior margin of mesoscutum in dorsal view and </p>
            <p>tegula width/ITS&gt; 0.23) and densely, distinctly punctate (i &lt;1 pd), sometimes becoming more sparsely punctate medially (i ≤ 1.5 pd); mesepisternum usually imbricate and moderately densely punctate (i ≤ 1.5 pd) with distinct interspaces; mesoscutum with dense plumose setae 1 OD long or slightly more (all setae separated by less than half their length in lateral view); T2–T3 with extensive basolateral fine tomentum covering about half length of segment laterally and apical impressed areas minutely punctate with fine setae associated with punctation.</p>
            <p>Males have the tegula large and densely punctate (as in the female, but punctures not becoming sparser medially); mesepisternum shiny and moderatly sparsely punctate at least in ventral half (i = 1–2 pd); and mesoscutum with dense plumose setae about 1 OD long (as in the female).</p>
            <p>Differential diagnosis</p>
            <p> Both sexes of the  L. stictaspis species complex are most similar to  L. yucatanense sp. nov. ,  L. paralepidii sp. nov. , and  L. aureoviride sp. nov. Both sexes of  L. yucatanense have the mesoscutum with sparser, shorter setae (most setae separated by half or more their length in lateral view); females of  L. yucatanense also have the mesepisternum strongly imbricate to finely rugulose with indistinct punctures at least in dorsal portion and T2–T3 apical impressed areas largely glabrous; males of  L. yucatanense have the mesepisternum shiny and densely and distinctly punctate (i &lt;1 pd). Both sexes of  L. paralepidii and  L. aureoviride have the mesepisternum much more densely punctate (i &lt;1 pd). </p>

These sequences are distinct from those of other Yucatán species (maximum intraspecific p-distance 0.6%; minimum interspecific distance (to  L. aureoviride sp. nov. ) 3.77%) but poorly distinguished from other members of the  L. stictaspis species complex (minimum p-distance 0.15%). </p>
            <p>Remarks</p>
            <p> Common. The  L. stictaspis species complex is a subset of the  L. gemmatum species complex. The Yucatán morphospecies corresponds to mOTU 3 in Landaverde-González et al. (2017a). </p>

            <p> Lasioglossum (Dialictus) ameshoferi Landaverde-González sp. nov.</p>
            <p>urn:lsid:zoobank.org: act: 56635D12-86E3-4758-B5A1-BFE003DBAF00</p>
            <p>Figs 5G–H, 6D, 13–14, 25A, 26A, 34C</p>
            <p>Diagnosis</p>
            <p> Females of  L. (D.) ameshoferi sp. nov. can be recognised by the combination of tegula small and ovoid with inner posterior angle not produced mesally (tegula width/ITS 0.21–0.22), clearly not reaching posterior margin of mesoscutum in dorsal view, and impunctate except for scattered minute punctures in anterior half; frons punctures as large and dense as those of lower paraocular area; mesoscutum with large, coarse and dense punctures (i &lt;1 pd), crowded laterad of parapsidal lines (i = 0 pd) except on anteromedian margin (i&gt; 1.5 pd); mesepisternum strongly rugose with the upper part areolate; metapostnotum shiny with strong subparallel rugae usually reaching posterior margin; and propodeum with strong U-shaped oblique carina sharply delineating metapostnotum. Males have the tegula small and ovoid (as in the female); frons punctures as large and dense as those of lower paraocular area, which is clearly visible beneath sparse appressed tomentum; metapostnotum with strong subparallel rugae reaching or nearly reaching posterior margin; and propodeum with trace of oblique carina present (this is unusual for males which almost always lack an oblique carina even when it is well-developed in the female). </p>
            <p>Differential diagnosis</p>
            <p> Both sexes of  Lasioglossum (Dialictus) ameshoferi sp. nov. are most similar to  L. (D.) nanotegula sp. nov. and females of  L. (D.) milpa sp. nov. (the male is unknown). Females of  L. ameshoferi are also similar to an undescribed species known from higher elevations in the mountains of Chiapas. Both sexes of  L. (D.) nanotegula have the frons punctures much smaller and denser than those of the lower paraocular area, which in the male is partially obscured by dense appressed tomentum; females also have the propodeum with an oblique carina straight; and males have the propodeum without a trace of an oblique carina. Females of  L. milpa also have the metapostnotum dull, imbricate, with shallow anastomosing rugae reaching posterior margin or nearly so and mesepisternum slightly sparsely punctate (i ≤ 1–1.5d), while females of  L. nanotegula have the mesoscutum punctures laterad of the parapsidal lines moderately dense but not crowded (i ≤ 1 pd). Females of the undescribed Chiapas species have the frons punctures much smaller and denser than those of the lower paraocular area. </p>
            <p> Lasioglossum ameshoferi sp. nov. is very similar to the Panama species  L. strigosigena Michener, 1954 , and diagnostic characters separating the two are not well known. It seems that the postgena of  L. ameshoferi is mostly smooth, while in  L. strigosigena it is entirely and strongly lineate, but a few specimens of  L. ameshoferi approach the condition found in  L. strigosigena . Geography is probably the most reliable way to separate these species. </p>
            <p>Etymology</p>
            <p>The specific epithet is dedicated to Andreas Ameshofer for his great support to PLG and his love and patience during the development of the entire study.</p>

            <p>Distribution</p>
            <p>Yucatán Peninsula and Pacific coast from Oaxaca to Jalisco.</p>
            <p>Remarks</p>
            <p> Uncommon.  Lasioglossum ameshoferi sp. nov. has an unusual distribution which seems to cross from the Atlantic coast to the Pacific coast at the Isthmus of Tehuantepec. It is not known from the Atlantic coast west of the isthmus or the Pacific coast east of the isthmus. Specimens from both sides are nearly identical both morphologically and in their DNA barcodes, precluding any consideration of splitting the populations into separate species. It is possible that additional sampling will reveal a more extensive distribution. This species is a member of the informal  L. comulum species group and corresponds to mOTU 7 in Landaverde-González et al. (2017a). </p>

            <p> Lasioglossum (Dialictus) aureoviride Landaverde-González &amp; Husemann sp. nov.</p>
            <p>urn:lsid:zoobank.org: act: C0BCD1CE-12B0-4363-AD44-D4B628683ACC</p>
            <p>Figs 5E–F, 6E, 15–16, 28B, 32A, 35A</p>
            <p>Diagnosis</p>
            <p> Females of  L. (Dialictus) aureoviride sp. nov. can be recognised by the diagnostic combination of tegula enlarged (reaching posterior margin of mesoscutum in dorsal view or nearly so and tegula width/ITS 0.21–0.24), with inner posterior margin straight, and scattered minute punctures (i ≥ 1.5 pd), becoming moderately dense on posterior margin (i = 1–2 pd) but still inconspicuous, smaller than those of mesoscutum; mesepisternum very densely punctate (i &lt;0.5 pd); mesoscutum weakly tessellate and sparsely punctate between parapsidal lines (i = 1–3 pd) and with dense plumose setae about 1 OD long (all setae less than half their length from each other in lateral view); supraclypeal area sparsely punctate (i = 1–3 pd); metapostnotum dull with shallow rugae blending into finely reticulate background microsculpture; T2–T3 apical impressed areas evenly covered with minute punctures and fine setae. Males may be recognised by the same characters, except the tegula is often more distinctly, but still sparsely punctate (i = 1–3 pd) and the T2–T3 apical impressed areas are impunctate. </p>
            <p>Differential diagnosis</p>
            <p> Both sexes of  Lasioglossum (Dialictus) aureoviride sp. nov. are most similar to  Lasioglossum (Dialictus) paxtoni sp. nov. ,  Lasioglossum (Dialictus) yucatanense sp. nov. , to species within the  L. stictaspis species complex and  L. paralepidii sp. nov. , all found on the Yucatán Peninsular, the subtropical Florida species  L. lepidii (Graenicher, 1927) , and some possible undescribed species occurring in other parts of Mexico. Both sexes of all of these undescribed Mexican species have the tegula more distinctly and densely punctate (i = 1–3 pd in females, i ≤ 1 pd in males) and the metapostnotum shiny with strong, coarse rugae. Both sexes of  L. paralepidii and  L. lepidii also have the mesoscutum densely punctate (i ≤ 0.5–1 pd), becoming moderately sparse submedially and anteromedially (i = 1–2 pd), and both sexes of  L. paralepidii have the supraclypeal area shiny and very densely punctate (i ≤ 0.5–1 pd). For differences between  L. (D.) aureoviride and  L. (D.) paxtoni see above in the diagnosis for the latter. For differences between  L. (D.) aureoviride and  L. (D.) yucatanense see above in the diagnosis for the latter. For differences between  L. (D.) aureoviride and the species of the  L. stictaspis species complex see above in the diagnosis for that complex. </p>
            <p>Etymology</p>
            <p> The specific epithet ‘  aureoviride ’ is a combination of the Latin adjectives ‘ aureum ’ (‘golden’) and ‘ viride ’ (‘green’), referring to the presence of both colours on the thorax. </p>

            <p>DNA barcodes</p>
            <p> Twenty-five sequences available (BOLD process IDs: LDSPS052-15 to LDSPS076-15). The holotype and male paratype are GenBank accession: KU574945. BOLD process ID: LDSPS065-15, paratype male GenBank accession: KU574946. BOLD process ID: LDSPS064-15. These sequences are very variable (maximum intraspecific p-distance 1.63%; minimum interspecific p-distance (to  L. lepidii ) 2.15%). This group of sequences is tentatively attributed to  L. aureoviride sp. nov. , although they share similarity with  L. lepidii sequences. Some sequences are likely attributable to  L paralepidii sp. nov. as well, but the intraspecific variation is too great to distinguish species within the broader  L. lepidii species complex. </p>

            <p> Lasioglossum (Dialictus) paralepidii Gardner sp. nov.</p>
            <p>urn:lsid:zoobank.org:act: D68E4E0E-879C-4944-9AFE-025ADC3580AE</p>
            <p>Figs 6F, 17–18. 29B, 31B, 32B, 35B, 36B</p>
            <p>Diagnosis</p>
            <p> Females of  L. paralepidii sp. nov. can be recognised by the diagnostic combination of tegula enlarged (reaching posterior margin of mesoscutum in dorsal view), sparsely punctate (i = 1–3 pd), becoming dense on lateral and posterior margins (i ≤ 1 pd), and with inner posterior margin weakly concave; mesoscutum densely punctate (i ≤ 0.5–1 pd), becoming moderately sparse submedially and anteromedially (i = 1–2 pd); supraclypeal area very densely punctate (i ≤ 0.5–1 pd); mesepisternum very densely punctate (i &lt;0.5 pd); metapostnotum mostly shiny with weak microsculpture and strong anastomosing rugae reaching posterior margin; and T2–T3 apical impressed areas evenly covered with dense, short, simple setae. Males can be recognised by the same characters, except the tegula is more densely punctate (i ≤ 1 pd), the metapostnotum shiny with strong anastomosing rugae, and the metasomal terga apical impressed areas are glabrous. In addition, the paraocular area is covered with dense appressed tomentum contrasting with the clypeus and supraclypeal area, which are mostly bare. </p>
            <p>Differential diagnosis</p>
            <p> Both sexes of  L. paralepidii sp. nov. are most similar to  L. aureoviride sp. nov. and some members of the  L. stictaspis species complex. They are also very similar to the subtropical Florida species  L. lepidii . See the differential diagnoses for  L. aureoviride and the  L. stictaspis species complex for comparison. Males of  L. lepidii have the face below the eye emargination, including the clypeus and supraclypeal area, completely covered with dense appressed tomentum. Females of  L. lepidii are morphologically nearly identical to  L. paralepidii sp. nov. , and reliable diagnostic characters separating the two are not known; it is best to identify females by geography and/or in association with males. </p>
            <p>Etymology</p>
            <p> The specific epithet ‘  paralepidii ’  sp. nov. is formed from the Greek prefix ‘ para -’ (‘near’) and the specific epithet ‘  lepidii ’, referring to its close relationship to  L. lepidii . </p>

            <p>Distribution</p>
            <p>Only known from the Yucatán Peninsula.</p>
            <p>Remarks</p>
            <p> Uncommon. Some morphologically similar specimens were examined from María Cleofas, Isla Tres Marías, Nayarit. These specimens have the metapostnotum rugae not reaching the posterior margin and are believed to be an undescribed species. It seems likely that there is a large complex including many undescribed species related to  L. lepidii ,  L. aureoviride sp. nov. , and  L. paralepidii sp. nov. occurring throughout the Neotropics. Further revisionary work is needed to elucidate this complex.  Lasioglossum paralepidii is a member of the  L. gemmatum species complex and partially corresponds to mOTU 5 in Landaverde-González et al. (2017a). </p>

            <p> Lasioglossum (Dialictus) milpa Landaverde-González sp. nov.</p>
            <p>urn:lsid:zoobank.org: act: 6D61F2D7-BF99-4B3E-8560-01405B0F3977</p>
            <p>Figs 6G, 19, 25C, 27A</p>
            <p>Diagnosis</p>
            <p> Females of  L. (D.) milpa sp. nov. can be recognised by the diagnostic combination of tegula small, ovoid, not produced mesally (tegula width/ITS &lt;0.20), and impunctate; frons punctures much smaller and denser than those of lower paraocular area; mesoscutum sparsely punctate between parapsidal lines (i = 1.5–3 pd), becoming moderately dense but not crowded laterad of parapsidal lines (i = 1 pd); metapostnotum dull, imbricate with shallow anastomosing rugae reaching posterior margin or nearly so; and head about as long as broad (length/width 0.95–0.99). The male is unknown. </p>
            <p>Differential diagnosis</p>
            <p> Females of  Lasioglossum (D.) milpa sp. nov. are most similar to those of  L. (D.) ameshoferi sp. nov. ,  L. (D.) nanotegula sp. nov. , and  L. (D.) aureoviride sp. nov. Females of  L. ameshoferi also have the frons punctures as large and dense as those in the lower paraocular area and the mesoscutum much more coarsely and densely punctate laterad of the parapsidal lines (i = 0 pd). Females of  L. ameshoferi and  L. nanotegula have the metapostnotum shiny with strong and coarse rugae and the propodeum with its oblique carina U-shaped and extending onto the dorsolateral slope. Females of  L. aureoviride have the tegula enlarged (reaching posterior margin in dorsal view), with the inner posterior margin straight. </p>
            <p>Etymology</p>
            <p> The specific epithet ‘  milpa ’ is a noun in apposition that refers to the traditional agriculture that is mainly found in the region and apparently beneficial for the different species of  Lasioglossum (Dialictus) found there (Landaverde-González et al. 2017b). </p>

            <p>DNA barcodes</p>
            <p> Twenty-eight sequences available (BOLD process IDs: LDSPS077-15 to LDSPS095-15, LDSPS098-15, LDSPS099-15, LDSPS103-15 to LDSPS109-15). These sequences are extremely variable, and therefore poorly distinguished from those of other species (maximum intraspecific p-distance 2.45%; minimum interspecific p-distance (to  L. aureoviride sp. nov. ) 4.32%). This group of sequences is very tentatively attributed to  L. milpa sp. nov. based on their similarity to the L. sp. mex8 sequence (unfortunately the original specimen to be designated as holotype was destroyed), an undescribed species which is most morphologically similar to  L. milpa . However, it is possible that more cryptic species exists. </p>

            <p> Lasioglossum (Dialictus) nanotegula Landaverde-González &amp; Husemann sp. nov.</p>
            <p>urn:lsid:zoobank.org:act: 907458CF-52CC-464C-A761-66B9373D5153</p>
            <p>Figs 6H, 20–21, 25B, 26B, 27B, 34B</p>
            <p>Diagnosis</p>
            <p> Females of  L. (D.) nanotegula sp. nov. can be recognised by the diagnostic combination of tegula small, ovoid (tegula width/ITS &lt;0.20), and impunctate; frons punctures much finer and denser than those of lower paraocular area; head broader than long (length/width0.91–0.95); mesoscutum moderately sparsely punctate between parapsidal lines (i = 1–3 pd), becoming dense but not crowded laterad of parapsidal lines (i ≤ 1 pd); metapostnotum shiny to weakly tessellate with strong coarse rugae reaching posterior margin; and T1–T3 apical impressed areas evenly covered with fine sparse punctures (i = 1–3 pd) with short simple setae arising from them (except absent on T1 medially). Males can be recognised by the same characters (however, the single male available for study is missing the metasoma, so metasomabased diagnostic characters are uncertain); in addition, males have the paraocular area and lower frons with dense appressed tomentum. </p>
            <p>Differential diagnosis</p>
            <p> Females of  L. (D.) nanotegula sp. nov. are most similar to those of  L. (D.) milpa sp. nov. and  L. (D.) ameshoferi sp. nov. For comparison with  Lasioglossum (D.) ameshoferi see above in  L. (D.) ameshoferi</p>
            <p> differential diagnosis; however, the male of that species is unknown. For comparison with  L. (D.) milpa see above in  L. (D.) milpa differential diagnosis. </p>
            <p>Etymology</p>
            <p> The specific epithet ‘  nanotegula ’ is a combination of the Latin nouns ‘ nanus ’ (‘dwarf’) and ‘ tegula ’ (‘roof tile’, literally ‘covering instrument’, now applied to the sclerite covering the wing base). It refers to the small size of the tegula. </p>

            <p>Distribution</p>
            <p>Yucatán Peninsula, northern Chiapas, and northern Guatemala, possibly also the Pacific coast to Jalisco. The five outlier Jalisco specimens seem morphologically indistinguishable from this species, but until additional records are found to fill the distribution gap, the possibility that they are a cryptic species must be considered and they are therefore excluded from the paratype series.</p>
            <p>Remarks</p>
            <p> Uncommon. This species is a member of the informal  L. comulum species group and corresponds to mOTU 4 in Landaverde-González et al. (2017a). </p>

            <p>Remarks</p>
            <p> Rare on the Yucatán Peninsula. The identification of this species is somewhat uncertain because only a single male was discovered in the Yucatán Peninsula, while the holotype is a female. The specimen analysed is believed to be  L. deceptor and not the male of  L. tropicior based on the relatively long face and moderately dense mesoscutum punctures (i = 1–2 pd), which agree more closely with the holotype of  L. deceptor than with  L. tropicior . Furthermore, both these species were described from the same type locality, so it is assumed that if one occurs on the Yucatán Peninsula, the other is also likely to occur there. </p>

            <p> Uncommon on the Yucatán Peninsula (three specimens examined). The specimens closely match images of the holotype and agree with the original description (Ellis 1914), and the type locality in eastern Guatemala is on the southern edge of the Yucatán Peninsula, but we still consider the identifications somewhat uncertain because of the likelihood that this species (along with  L. deceptor ,  L. flaveriae (Mitchell, 1960) ,  L. gundlachii (Baker, 1906) ,  L. liguanense (Sandhouse, 1924) , and possibly  L. exiguum and  L. umbripenne (Ellis, 1913)) is part of a large and diverse complex including many undescribed species. Morphologically similar specimens which cannot be confidently assigned to a described species are common in other areas of Mexico. </p>
