Manota bisulca sp. n.

Figs. 6 A–E

Male. Colour. Head brown, face yellow. Antenna pale brown. Clypeus yellow, mouthparts pale yellowish. Thorax yellow, posteromedial part of scutum and scutellum brownish. Legs yellowish, apical third of femur 3 slightly infuscated. Wing pale brown; haltere yellow with brown knob. Abdominal tergites pale brown, medially at least seemingly darker brown, sternites yellowish. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4, Fig. 6 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.3 times longer than palpomere 4. Number of strong postocular setae 9–10. Thorax. Anepisternum setose, with 34–41 setae; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite non-setose, episternum 3 setose, with 13–20 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 1.5–1.7 mm. Hypopygium. Figs. 6 B–E: Sternite 9 laterally fused with gonocoxa except near the posterior margin, posterior margin transverse, 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 angled; ventral setae of gonocoxa unmodified. Posterolateral part of gonocoxa is drawn into a curved lobe, most of the setae of the lobe are arising from small ridge-like formations. Parastylar lobe membranous, covered by the gonocoxa, with one seta. No paraapodemal lobe observable. Dorsal mesial margin of gonocoxa convex, with two small setigerous lobes on posterior half. Number of juxtagonostylar setae two, the ventral one is an apically cloven flat megaseta, the dorsal one a flattened deeply cloven megaseta; the former is arising from a large basal body which is as long as the megaseta, the latter is arising from a short basal body at the base of the former. Anteriorly from the juxtagonostylar megasetae there is a plate-like lobe bearing anteriorly a long strong megaseta and posteriorly a comb-like row of 3 shorter megasetae. Posteriorly from the juxtagonostylar megasetae no prominent setae deviating from the other setosity. Otherwise the dorsal setae of gonocoxa similar to those on the ventral side. Gonostylus rather small, bilobed, the mesial lobe with one strong long seta and one short thin seta, the lateral lobe with a strong curved seta, otherwise the gonostylus non-setose. Aedeagus elongate subtriangular, without lateral shoulders, with straight sides, the apex curved ventrad. Hypoproct extending posteriorly to level of base of gonostyli, the number of ventral setae (sternite 10) ca. 15 on each side. Cerci mesially separate.

Female. Unknown.

Discussion. By 1) non-setose anterior basalare, 2) non-setose laterotergite, 3) long posterolateral lobes of the gonocoxa, 4) having the lateral margin of tergite 9 largely fused with the gonocoxa, 5) having 1+3 megasetae anteriorly from the juxtagonostylar megasetae on the plate-like lobe on dorsal side of the gonocoxa, 6) having setose lobes on the dorsal mesial margin of gonocoxa and 7) having a subtriangular gonostylus (when seen from the broad side) with a long setae (among a few other setae) at the apicomesial angle and a curved seta at the apicolateral angle Manota bisulca is similar to M. corcovado , M. diversiseta and M. vexillifera . It differs from M. corcovado by having the anterior-most of the 1+3 megasetae on the plate like lobe on dorsal side of the gonocoxa simple instead of being apically remarkably expanded, and from M. corcovado and M. diversiseta by lacking a group of 3 lamella-like megasetae posteriorly from the juxtagonostylar megasetae.

Etymology. The name is Latin, bisulca , cloven, forked, referring to the forked juxtagonostylar megasetae.
