Figs 11 A–D
Male. Colour. Head brown, face somewhat paler. Antenna including scape and pedicel brown. Clypeus and mouthparts pale yellowish. Thorax light brown, medial part of scutum and scutellum darker. Legs yellowish, hind coxa basally and hind femur basally and apically slightly infuscated. Wing hyaline; haltere yellow with brown knob. Abdomen light brown, medial 2/3 of tergites darker. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Antennal flagellomere 4 Fig. 11 A. Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with five apically flattened and curved sensilla; palpal segment 4 with parasegment; palpal segment 5 ~1.8 times longer than palpal segment 4. Nine strong postocular setae. Thorax. Anepisternum with 51–70 setae; anterior basalare non-setose; preepisternum medially with patch of 24– 25 setae; laterotergite with 18–23 setae; metepisternum with 8 setae. Legs. Mid- and hind tibial organs absent. Wing. R1 meeting C within the basal half of the costal margin; the sclerotized part of M2 proximally not extending to the level of the tip of R1; wing length 2.2 mm. Hypopygium, Figs. 11 B–E. Sternite 9 elongate subquadrangular, about half the ventral length of gonocoxa, laterally separated from gonocoxa, anteriorly deeply incised, posteriorly with narrow v-shaped notch, the setae similar to the ventral setae of gonocoxa. Ventromedial margin of gonocoxa simple, slightly curved. The ventral setae of gonocoxa unmodified. Parastylar lobe obliquely transverse, apically tapering (to the medial end), with 5 long setae of which one is apical, two are ventral and two situated on posterior margin. Paraapodemal lobe similar to Fig. 2 B. Dorsomedial margin of gonocoxa simple, rather straight, with a stripe of short setae beyond the middle. Gonocoxa apicomedially with a large oblique lobe bearing ~8 apical setae and ~5 setae at its medial margin. The dorsal setosity of gonocoxa similar to the ventral one except a couple of longer setae posteriorly. Gonostylus about two thirds of the ventral length of gonocoxa, apicoposteriorly elongated with convex lateral and concave medial surface, apically with a long megaseta, other setosity unmodified, confined on lateral/ventral part, a few very long setae at medial margin; the microtrichia on the medial surface long and conspicuous. Two juxtagonostylar setae present, a shorter unmodified seta and a longer sigmoid megaseta, both arising from a common basal body that is much longer than the megaseta. Aedeagus elongate subtriangular, with weak lateral shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the base of gonostylus, its ventral part (sternite 10) with ~15 scattered setae on each half. Cerci separated in apical third by a U-shaped notch and have apical setae only
Female unknown.
Discussion. Manota pentachaeta belongs to a large group of species as defined under M. acris. Manota pentachaeta is distinguished from all of these in having all setae on the parastylar lobe very long, as long or longer than the lobe itself (in other species, a few long setae may situate only apically and/or medially). Manota pentachaeta differs from all but M. orthacantha in it unusually long antennal flagellomeres which are about twice as long as wide. See also discussion under M. apentachaeta.
Etymology. The name is a Latinized Greek noun pentachaeta [five-seta] referring to the five strong setae on the parastylar lobe.
