Hooked hairs are present on the stipes, on the prementum and on the first two segments of the labial palpus, except in A. halictoides, which lacks such hairs on the second segment of the palpus. One species, A. bonariensis, also has modified hairs on the hypostomal area of the head, on the trochanters, and on the metasomal sterna (Fig. 9C). Species of the group are 6.2–11.0 mm long. Males have a ventral tubercle in front of the middle coxa, except A. bonariensis which lacks the tubercles. Yellowish hairs are usually present on the metasomal apical bands and/or on the tibial scopa of females (Fig. 1), and males of some species are entirely covered by golden pile (A. ursinus, A. mesopotamica, A. duckei, and A. holmbergi), or nearly so (A. bonariensis) (Fig. 2).</p> </div>	http://treatment.plazi.org/id/039787BCFFEBFF9432B7F8F98972FEAE	Public Domain	No known copyright restrictions apply.

The genus Ancyloscelis differs from other genera of Emphorini by the presence of a paraocular carina along most of inner eye margin, the vein cu-v of hind wing less than half as long as second abscissa of vein M-Cu, the broad metapleura, the maxillary palpus of the female with sparse, short hairs, the mandible of the male short and gently curved, the T7 of the male rounded apically, the S7 of the male with a broad disc and two or four small apical lobes, shorter than the disc, and the large, curved male gonostylus, usually flattened and longer than the gonocoxite. Figures of the male hidden sterna and genitalia can be found in Michener (1954), Michener &amp; Moure (1957), and Rodríguez &amp; Roig-Alsina (2004).</p> <p>The genus is distributed from southern United States through tropical America to central Argentina.</p></div> 	http://treatment.plazi.org/id/039787BCFFEBFF9732B7FBEB8F38F969	Public Domain	No known copyright restrictions apply.

Females of A. mesopotamica are characterized by the strongly elevated, tuberculiform carina of the pronotal lobe (Fig. 12B). Males are distinguished by their golden pubescence (Fig. 2D), and the strong inner tooth on the basal third of the posterior basitarsus (Fig. 10D).</p> <p>Redescription. Male. Total length 8.20–9.90 mm. Length of forewing 6.70–7.80 mm. Color. Black, with following parts yellow: entire labrum, base of mandible, apical band on clypeus with trilobate basal margin, spot on apical 0.25 of under surface of scape, underside of first flagellomere and tarsi of all legs, except distotarsi brownish; following parts brownish: underside of flagellomeres 2–11, and tegula. Wings weakly infuscate, paler apically; veins and pterostigma blackish. Pilosity. With yellow-golden hairs all over the body, paler on underside of thorax. Scutum with two strata of hairs, one of dense, very short hairs (0.26–0.35x MOD) and another one of interspersed, long hairs (0.97–1.13x MOD). Hairs of mesopleuron 1.13–1.45x MOD. T1–T5 with entire apical bands. Structure. OOD 0.65x IOD. IAD 1.76x AOD. UID 1.12x LID. Width of head 1.55x length of head. Clypeocular distance 0.22–0.28x MOD.

Sculpture. Disc of clypeus with close, fine punctures (0.02–0.03 mm); disc of scutum with similar, nearly coalescent punctures (0.02–0.03 mm). Mesopleuron with punctures 0.03–0.04 mm, separated by polished interspaces 0.5–1.0 PD.</p> <p>Female. Total length 8.2–8.9 mm; length of forewing 5.2–6.9 mm. Color. Black; some specimens with brownish tegula and tarsi. Pilosity. With whitish hairs all over the body, paler on underside of thorax, but disc of T2–T4 and apical bands wite to yellowish; tibial scopa with yellow hairs dorsally and white hairs ventrally; prepygidial fimbria yellow. Scutum with two strata of hairs, one of dense, very short hairs (0.44–0.72x MOD) and another one of interspersed, long hairs (1.20–1.28x MOD). Hairs of mesopleuron 1.20–1.48x MOD. T1–T5 with entire apical bands. Structure. OOD 0.79x IOD. IAD 2.0x AOD. UID 1.0x LID. Width of head 1.30x length of head. Clypeocular distance 0.42x MOD. Lengths of first plus second labial palp segments 1.32x length of prementum. Labial palpus with modified setae on first and second segments. Carina of pronotal lobe forming strong tuberculiform elevation, concave posteriorly. Sculpture.

Mesopleuron with punctures 0.03–0.04 mm separated by polished interspaces 0.5–1.0 PD.</p> <p>Comments. Two syntypes of Leptergatis mesopotamica are preserved at MACN, both in poor condition. One specimen lacks most legs (only left middle leg and right hind leg remaining), and the right hind wing; the head is glued on a card. This specimen is selected as the lectotype, and bears the following labels: “C. 15.3.79,” “mesopotamica/ Holmberg” in Holmberg’s handwriting, and “ Leptergatis / mesopotamica H. / LECTOTYPUS / A. Roig-Alsina 2005.” The date on the label reads III, 15, 1879, although the date in the original description reads II, 15, 1879, probably a typographic error. The second specimen is badly damaged, remaining only part of the mesosoma with the wings and the left middle and hind legs. It bears the label “ Leptergatis / mesopota-/ mica/ Holmberg” and is designated as paralectotype.</p> <p>The male lectotype of A. turmalis was examined by one of us (ARA) and labeled as lectotype. It agrees in all characters with males of A. mesopotamica.</p> <p>Distribution. Argentina and Brazil. Argentina: provinces of Formosa, Corrientes, Chaco, Tucumán, and Buenos Aires.

Scale 2004	<div><p>Ancyloscelis saltensis Rodríguez &amp; Roig-Alsina</p> <p>(Figs. 6D, 7D, 8D, 11D, 13H)</p> <p>Ancyloscelis saltensis Rodríguez &amp; Roig-Alsina, 2004: 359-360, figs. 4, 8, 12, 14, 20, 22, 25 and 27(Holotype male, Argentina, Salta, Sumalao, II-1994, M. Fritz, MACN, examined)</p> <p>Diagnosis. This species is similar to A. romeroi in size (length of forewing 5.9–7.3 mm). It is distinguished by the color of the forewing, which has the entire apical margin darkened, and by the shorter pubescence. The hairs on the mesopleuron are 1.7–2.7x MOD (male) and 1.8–1.9x MOD (female). Males are characterized by the black scape and pedicel (8D). The shape of the hind basitarsus is similar to that of A. romeroi, with a basal inner rounded projection followed by a median tooth, but the apex is pointed (11D). The hidden sterna and genital capsule have been drawn by Rodríguez and Roig-Alsina (2004).</p> <p>Distribution.
