Figs. 7 A–E
Male. Colour. Head brown, face paler brown. Antenna pale brown. Clypeus and mouthparts pale yellowish. Thorax yellow, posteromedial part of scutum and scutellum rather brownish. Legs pale yellowish, apical fourth of femur 3 slightly infuscated. Wing pale brown; haltere yellow with brown knob. Abdomen yellowish, sternites paler than tergites. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4, Fig. 7 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.2 times longer than palpomere 4. Number of strong postocular setae 8–9. Thorax. Anepisternum setose, with 45–52 setae; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite non-setose, episternum 3 setose, with 7–11 setae. Legs. Mid and hind tibial organs absent. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 not extending to the level of the tip of R1; wing length 1.6–1.8 mm. Hypopygium. Figs. 7 B–E: Sternite 9 laterally fused with gonocoxa, posterior margin concave, extending just over the middle of gonocoxa, anterior margin deeply incised, the setae similar to the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa with broad curved lobe lying over the membranous parastylar lobe which bears one seta; ventral setae of gonocoxa unmodified except for a strong seta at the margin of the mesial lobe. Posterolateral part of gonocoxa is drawn into a short subtriangular lobe, at least some of its setae arising from small ridge-like formations. No paraapodemal lobe observable. Dorsal mesial margin of gonocoxa simple. Number of juxtagonostylar setae two, the ventral one is a rather weakly modified flattened megaseta arising from a strong basal body which is as long as the seta, the dorsal one is an apically flattened and expanded megaseta with a whip-like branch and arising from the side of the basal body of the former. Anteriorly from the juxtagonostylar megasetae there is a plate-like lobe bearing anteriorly a long apically expanded megaseta and posteriorly 2+2 shorter blunted megasetae. Posteriorly from the juxtagonostylar megasetae there is a lobe bearing apically a few setae one of which flattened and flame-shaped. Otherwise the dorsal setae of gonocoxa similar to those on the ventral side. Gonostylus flat, subtriangular, with a small apicolateral lobe, with a seta at apex and a longer and a shorter seta at apicomesial angle, otherwise the gonostylus is non-setose. Aedeagus broadly subtriangular, without lateral shoulders, with convex sides, the apex curved ventrad. Hypoproct extending posteriorly to level of middle of gonostyli, the form unusual, divided into broader anterior and narrower posterior parts, the number of ventral setae (sternite 10) circa 30 on each half. Cerci mesially separate.
Female. Unknown.
Discussion. Manota depilis is similar to M. vexillifera by 1) the non-setose anterior basalare, 2) the non-setose laterotergite, 3) presence of posterolateral lobes on the gonocoxa, 4) tergite 9 laterally fused with the gonocoxa, 5) the apically expanded anterior-most megasetae situated anteriorly from the juxtagonostylar megasetae on the dorsal side of the gonocoxa and 6) the subtriangular gonostylus (when seen from the broad side) with a long seta (together with a shorter one) at the apicomesial angle and a curved seta at the apicolateral angle. It is distinguished by having 1) the mentioned megaseta less modified: the apically expanded club-like part being ca. 3 times broader than the basal part instead of being ca. 10 times broader and flag-like, and 2) 4 megasetae between this expanded megaseta and the juxtagonostylar megasetae instead of 3. Further, in M. depilis, sternite 9 is laterally completely fused with the gonocoxa, whereas there is a short delimited posterior part in M. vexillifera. The two species are abundantly different in numerous other minor details in their hypopygiums (see Fig. 7, Jaschhof & Hippa 2005: fig. 15).
Etymology. The name is Latin, depilis, without hairs, referring to the non-setose ventral surface of the gonostylus.
