The dorsal color pattern is distinctive with a large dark brown region on the elytron medially near the suture and with a large, diffuse pale macula apicomedially and along the lateral margins to the apex (Fig. 13). The male genitalia are distinctive with the male median lobe straight and apically sharply pointed in lateral aspect (Fig. 14) and broad and apically broadly truncate in ventral aspect (Figs 15, 16). The lateral lobe is moderately broad with the apices sharply curved mediad with a distinct, small, elongate apical tooth (Figs 16, 17).  Desmopachria amyae Miller, from Bolivia, has very similar genitalia including the apical tooth on the lateral lobe (Miller 2001: fig. 2), but that species has a different color pattern, an elytral sutural stria, and lateral furrows on the elytron (Miller 2001) which are missing in  Desmopachria apicodente .  Desmopachria lateralis, also from Venezuela, also has a minute apical tooth on the lateral lobe, but a different dorsal color pattern, a distinct carina along the lateral margin of the elytron, and the male median lobe is differently shaped, with a distinctive subapical expansion on the ventral margin medially (Fig. 20).</p><p>Description.</p><p>Measurements.

Specimens are moderately large for  Desmopachria species (TL = 1.7-1.8 mm). The dorsal color pattern is distinctive in many specimens with most of the elytron brown with a broad region longitudinally along the suture dark brown (Figs 18, 19). The male genitalia are distinctive with the median lobe in lateral aspect elongate, sublinear along the dorsal margin and medially expanded along the ventral margin and apically narrowly rounded (Fig. 20). In ventral aspect the median lobe is broad with the lateral margins slightly convergent to the broadly truncate apex (Fig. 21). The lateral lobe is moderately broad basally and narrowed apically to a narrowly rounded apex, apically with a small, elongate apical tooth (Fig. 22). See under  Desmopachria apicodente for additional diagnostic differences between that species,  Desmopachria amyae, and  Desmopachria lateralis .</p><p>Description.</p><p>Measurements.

Body very broad, rounded, laterally broadly rounded, lateral margins slightly discontinuous between pronotum and elytron; dorsoventrally somewhat compressed.</p><p>Coloration. Head pale orange. Pronotum pale orange with narrow dark area medially along posterior margin. Elytron dark orange, with broad dark brown band longitudinally along suture, also with small diffuse, pale macula at apex, and paler diffuse areas anteromedially (Fig. 18). Ventral surfaces yellow to orange.</p><p>Sculpture and structure. Head broad, short; anterior margin of clypeus finely margined with continuous narrow bead, bead slightly more expanded medially; surface of head shiny, punctures extremely fine, nearly impunctate; eyes large (HW/EW = 1.9-2.0); antennae short, scape and pedicel relatively large and rounded, flagellomere III long and slender, apically expanded, antennomeres IV-X short and broad, antennomere XI elongate, apically pointed. Pronotum short, lateral margins short, curved with continuous narrow bead; surface shiny, punctation very fine over most of surface, larger and denser posteromedially. Elytron broad, laterally broadly curved; surface shiny, punctation variable, some punctures arranged into indistinct series, especially anteromedially (Fig. 18); lateral margin, dorsad of epipleural carina, with distinct, longitudinal carina extending from humeral angle most of length of elytron (Fig. 19). Prosternum extremely short, longitudinally compressed, medially flattened; prosternal process short, broad, flattened, apically pointed. Metaventrite broad and evenly smoothly convex medially, surface shiny, impunctate; metaventrite wings extremely slender. Metacoxa with medial portion short, &lt;1/3 length of metaventrite medially, metacoxal lines slightly sinuate, divergent anteriorly; lateral portion of metacoxa extremely large, anteriorly strongly expanded; surface shiny, impunctate, slightly rugulose. Metatrochanter very large, longer than length of ventral margin of metafemur; legs otherwise not noticeably modified. Abdomen with surfaces shiny and smooth, surface impunctate.</p><p>Male genitalia. Male median lobe in lateral aspect moderately broad, elongate, straight, with submedial expansion on ventral surface, apex narrowly rounded (Fig. 20); in ventral aspect elongate and broad, apex broadly subtruncate, slightly emarginate (Fig. 21). Lateral lobe elongate, moderately broad medially, apically narrowed to apex, apex sharply curved mediad with small but distinctive elongate  “tooth” at apex (Fig. 22).</p><p>Sexual dimorphism. No obvious external sexual dimorphism was observed.</p><p>Variation.

The male genitalia are distinctive with the median lobe shorter than half the length of the lateral lobes, broad and apically truncate and the lateral lobes elongate, apically somewhat expanded and with a dense series of elongate setae on the apicomedial surface (Fig. 4). Specimens are rather large for  Desmopachria (TL = 2.6-2.8 mm). This species is similar to members of the  Desmopachria portmanni group, especially  Desmopachria grammosticta Braga &amp; Ferreira-Jr., which also has linear series of elytral punctures. However,  Desmopachria lineata does not have the characteristic sexually dimorphic prosternal process of the  Desmopachria portmanni species-group (including  Desmopachria grammosticta). The prosternal process in males of  Desmopachria lineata is not bifurcate with a medial pit, instead it is similar to the process in females. This is an unusual species in that it appears phonetically similar to members of the  Desmopachria portmanni group, but it lacks the bifid male prosternal process. It is certainly possible that the character states and relationships among these taxa is more complicated than currently understood. It seems clear that investigation of the utility and diversity of these and other characters among this group of  Desmopachria should be investigated in the future.</p><p>Description.</p><p>Measurements. TL = 2.6-2.8 mm, GW = 1.9-2.0 mm, PW = 1.4-1.5 mm, HW = 1.0 mm, EW = 0.5-0.6 mm, TL/GW = 1.4, HW/EW = 1.8. Body large for genus, very broad, rounded, laterally broadly curved, lateral margins slightly continuous between pronotum and elytron, body broadest across elytra anterior at ca. midlength of body (Fig. 3).</p><p>Coloration. Dorsal surface of head, pronotum and elytron red brown, moderately uniform in color throughout. Head appendages, pro- and mesothoracic legs and ventral surfaces of head and prothorax orange; other ventral surfaces red.</p><p>Sculpture and structure. Head broad, anteriorly produced in rounded lobe; anterior margin of clypeus curved, flattened, margined with conspicuous, continuous flattened bead; surface of head shiny, finely but distinctly punctate over entire surface; eyes moderately large (HW/EW = 1.8); antennae short, scape and pedicel relatively large and rounded, flagellomere III long and slender, apically expanded, antennomeres IV-X short and broad, lobed at anterodorsal angle, antennomere XI elongate, apically pointed. Pronotum very short, lateral margins short, broadly curved, more so anteriorly, with continuous narrow bead; surface shiny, coarsely punctate medially and along most of anterior margin, less punctate lateromedially, punctures irregular, some confluent. Elytron moderately broad, laterally broadly curved; surface shiny, more coarsely punctate than pronotum, punctation distinctive and prominent, irregular, many punctures confluent forming distinctive longitudinal lines and grooves. Prosternum extremely short, longitudinally compressed, medially slightly carinate; prosternal process slender anteriorly, with distinctive, low medial tubercle, apical portion broad basally with broad basal U-shaped region and concave slender apical process emerging from between branches of U, apically narrowly rounded. Metaventrite broad and evenly convex medially, surface shiny, coarsely punctate, punctures forming longitudinal, linear series; metaventrite wings extremely slender. Metacoxa with medial portion short, &lt;1/3 length of metaventrite medially, metacoxal lines slightly divergent anteriorly; lateral portion of metacoxa extremely large, anteriorly strongly expanded; surface shiny, evenly and coarsely punctate.

Male median lobe in dorsal aspect short and broad, &lt;1/2 length of lateral lobe, apex slightly broadened, apically truncate with rounded lateral margins, medially very finely emarginate, (Fig. 4). Lateral lobe in dorsal aspect slender, elongate, evenly expanded apically and broadly curved mediad, apicomedial surface with dense, long setae (Fig. 4).</p><p>Sexual dimorphism. No obvious sexual dimorphic features were discovered.</p><p>Variation. There is some degree of variation in the punctation on the pronotum, elytron and ventral surfaces from specimen to specimen with some with punctures coarser, more confluent, with more strongly marked linear series.

Specimens are similar to those of  Desmopachria cavia Braga &amp; Ferreira Jr. in size, shape, general features, and the presence of a setose depression medially on abdominal sternite VI. However,  Desmopachria pseudocavia has a distinctly different dorsal color pattern (Fig. 43; Braga and Ferreira-Jr. 2010: fig. 3A) and similar, but differently shaped male genitalia. In  Desmopachria pseudocavia the male median lobe terminates in two short rami which are apically rounded and evenly and strongly curved mediad (Fig. 45). In  Desmopachria cavia these rami are more linear and are apically more distinctly pointed (Braga and Ferreira-Jr. 2010: figs 3D, E). Also, although both species are extremely small diving beetles,  Desmopachria pseudocavia (TL = 1.1-1.2 mm) are even smaller than  Desmopachria cavia (TL = 1.3-1.5 mm, Braga and Ferreira-Jr. 2010).</p><p>Description.</p><p>Measurements. TL = 1.1-1.2 mm, GW = 0.8 mm, PW = 0.6 mm, HW = 0.4-0.5 mm, EW = 0.2 mm, TL/GW = 1.4-1.5, HW/EW = 2.3-2.4. Body broad, ovoid, laterally broadly curved, lateral margins continuous between pronotum and elytron, body broadest across elytra at midlength of body (Fig. 43).</p><p>Coloration. Dorsal surface of head and pronotum yellow. Elytron brown with diffuse, complex maculae, margins of maculae indistinct (Fig. 43). Head appendages, legs, and ventral surfaces yellow.</p><p>Sculpture and structure. Head broad, anteriorly rounded, anterior margin of clypeus curved, flattened, margined with conspicuous, continuous flattened narrow bead; surface of head shiny, very finely and sparsely punctate; eyes very large (Fig. 43, HW/EW = 2.3-2.4); antennae short, scape and pedicel relatively large and rounded, flagellomere III long and slender, apically expanded, antennomeres IV-X short and broad, lobed at anterodorsal angle, antennomere XI elongate, apically pointed. Pronotum short, lateral margins short, curved with continuous narrow bead of even width throughout; surface shiny, impunctate to very finely and sparsely punctate. Elytron broad, laterally broadly curved; surface shiny, very finely and sparsely punctate. Prosternum extremely short, longitudinally compressed, medially slightly carinate; prosternal process slender anteriorly, with distinctive, small, sharp medial tubercle, apically short and broad, medially slightly carinate, concave, apically acutely pointed. Metaventrite broad and evenly smoothly convex medially, surface shiny, impunctate; metaventrite wings extremely slender. Metacoxa with medial portion short, &lt;1/3 length of metaventrite medially, metacoxal lines divergent anteriorly; lateral portion of metacoxa extremely large, anteriorly strongly expanded; surface shiny, impunctate. Metatrochanter large, subequal to length of ventral margin of metafemur; legs otherwise not noticeably modified. Abdomen with surfaces shiny and smooth, very finely and sparsely punctate; abdominal sternite VI with medial longitudinally oval depression with field of setae around margins (Fig. 44).</p><p>Male genitalia. Male median lobe in lateral aspect short, slightly curved ventrad; in ventral aspect broad basally, narrowed apically, apex formed as lateral, curved rami with medial rounded emargination (Fig. 45). Lateral lobe in ventral aspect robust, subapically concave on lateral margin, apex truncate, with distinct small subapical articulable process (Fig. 45).</p><p>Sexual dimorphism. No obvious sexually dimorphic features were discovered.</p><p>Variation. There is substantial variation in the extent and distinctiveness of the dorsal coloration on the elytra (Fig. 43), though the basic pattern seems to be conserved. The humeral and anteromedial maculae and the apical maculae are nearly always present and distinctive. The medial longitudinal macula and lateral maculae are range from nearly absent to vague or indistinct to distinctive.</p><p>Etymology.</p><p>This species is named  Desmopachria pseudocavia, Latin for resembling  Desmopachria cavia, for the similarities of this species to  Desmopachria cavia Braga &amp; Ferreira Jr.</p><p>Distribution.</p><p>This species is known from Venezuela from the states of Amazonas, Anzoategui, Apure, Bolivar, and Monagas (Fig. 78).</p><p>Type material.</p><p>Holotype in MIZA, male labeled, "VENEZUELA: Amazonas State 4°58.838'N, 67°44.341'W; 95m Communidad  Caño Gato, on Rio Sipapo; 16.i.2009; leg.

The dorsal punctation on the head, pronotum and elytra is very fine and sparse. The elytra are iridescent. The genitalia are somewhat similar to  Desmopachria mutata Sharp, but that species has the median lobe very slender, not as broadly expanded apically, and apically rounded, not truncate (Young 1995: fig. 2). That species also occurs in Mexico, not northern South America (Young 1995).  Desmopachria truncata is otherwise not similar to other species in the  Desmopachria portmanni-aldessa subgroup.</p><p>Description.</p><p>Measurements. TL = 2.0-2.1 mm, GW = 1.3-1.4 mm, PW = 1.0-1.1 mm, HW = 0.6-0.7 mm, EW = 0.3-0.4 mm, TL/GW = 1.4-1.5, HW/EW =1.8-2.2. Body very broad, laterally rounded, lateral margins continuous between pronotum and elytron; dorsoventrally compressed.</p><p>Coloration. Head and pronotum evenly dark orange, head slightly iridescent dorsally. Elytron evenly dark orange, iridescent, especially apically. Ventral surface of head, prosternum, head appendages, and pro- and mesolegs yellow, other ventral surfaces and metalegs darker orange, lateral portion of metacoxa and abdominal ventrites somewhat iridescent.</p><p>Sculpture and structure. Head broad, short; anterior margin of clypeus finely margined with continuous flattened narrow bead; surface of head shiny, punctation extremely fine, sparse but evenly distributed; eyes moderately large (HW/EW = 1.8-22); antennae short, scape and pedicel relatively large and rounded, flagellomere III long and slender, apically expanded, antennomeres IV-X short and broad, antennomere XI elongate, apically pointed. Pronotum short, lateral margins short, broadly curved with continuous narrow bead; surface shiny, punctation very fine, irregular, sparse; posterior margin sinuate. Elytron broad, laterally broadly curved; surface shiny, punctate, punctures dual, fine and large interspersed, without linear series. Prosternum extremely short, longitudinally compressed, medially slightly carinate; prosternal process in male very slender anteriorly, with low, indistinct medial tubercle, bifid apically with deep medial pit, in female slender anteriorly, with distinctive, small medial tubercle, apically short and broad, medially slightly carinate, apically acutely pointed. Metaventrite broad and evenly smoothly convex medially, surface shiny, impunctate; metaventrite wings extremely slender. Metacoxa with medial portion short, &lt;1/3 length of metaventrite medially, metacoxal lines sinuate, divergent anteriorly; lateral portion of metacoxa extremely large, anteriorly strongly expanded; surface shiny, impunctate. Metatrochanter very large, subequal to length of ventral margin of metafemur; legs otherwise not noticeably modified. Abdomen with surfaces shiny and smooth, very finely and sparsely punctate.</p><p>Male genitalia. Male median lobe in lateral aspect elongate, evenly curved, apically narrowly rounded (Fig. 63; in ventral aspect elongate, evenly constricted medially, expanded apically to abruptly broadly truncate apex (Fig. 64). Lateral lobe extending distinctly beyond apex of median lobe, moderately broad, apically rounded with dense margin of long setae apically and along apicodorsal margin (Fig. 65).</p><p>Sexual dimorphism. Male pro- and mesotarsomeres I-III slightly more broadly expanded and with ventral adhesive setae. Male and female prosternal processes different as in all  Desmopachria portmanni group species.</p><p>Variation. The single specimen from "Upper Palumeu" has the male median lobe slightly longer and more slender with the lateral lobes apically a little more rounded. This does not seem to represent a significant difference however, and the specimen is from the same general area as the holotype. The series from Guyana similarly has some shape variation in the lateral and median lobes, but again, it does not seem to suggest species-level differences. However, additional specimens could help clarify the limits in these populations. A couple specimens are paler tan in color, but this could be because they are teneral.</p><p>Etymology.</p><p>This species is named  Desmopachria truncata, Latin for the characteristic apically truncate male median lobe in this species.</p><p>Distribution.</p><p>This species is known from Sipaliwini District, Suriname and Region VIII, Guyana (Fig. 81).</p><p>Type material.</p><p>Holotype in NZCS, male labeled, "SURINAME: Sipaliwini District 2.97731°N, 55.38500°W 200 m Camp 4 (low, Kasikasima; sandy stream on trail to METS camp 20.iii.2012; SR12-0320-02A leg.
