Manota feminea sp. n.

Figs 7 A–F

Male. Colour. Head brown, face somewhat paler. Antenna including scape and pedicel light brown. Clypeus and mouthparts pale yellowish. Thorax yellow, medial part of scutum and scutellum somewhat darker. Legs yellowish, hind coxa basally slightly infuscated. Wing hyaline; haltere yellow with brownish 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. 7 A. Palpal segment 3 of maxillary palpus with apicomedial thumblike extension, with five apically strongly flattened and curved sensilla; palpal segment 4 with parasegment; palpal segment 5 ~1.6 times longer than palpal segment 4. Nine strong postocular setae. Thorax. Anepisternum with 44 setae; anterior basalare non-setose; preepisternum with 18 setae; laterotergite with 29 setae; metepisternum with 10 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 1.6 mm. Hypopygium, Figs. 7 B–F. Sternite 9 large, elongate subquadrangular, almost as long as the ventral length of gonocoxa, laterally free from gonocoxa, anteriorly deeply incised, the setae similar to the ventral setae of gonocoxa, slightly increasing in size towards posterior margin. Ventromedial margin of gonocoxa simple, curved. The ventral setae of gonocoxite unmodified. Parastylar lobe obliquely transverse, with 4–5 setae ventrally and 2–3 setae dorsally. Paraapodemal lobe similar to Fig. 2 B. Dorsomedial margin of gonocoxa curved, with rather weakly expressed row of short setae at the middle; posteriorly at the dorsomedial margin a thumb-like lobe bearing ~8 setae on its dorsal side. The posterior marginal area simple. The dorsal setosity of gonocoxa unmodified, similar to the ventral one. Gonostylus rather small, about half of the length of gonocoxa, anteroposteriorly elongated with convex lateral and concave medial surface, apically with a long megaseta, other setosity unmodified but rather long, a fringe of long straight setae on ventromedial margin, a row of shorter setae on medial surface; medial surface with few conspicuously long microtrichia. Two juxtagonostylar setae present, one a fine seta, the other a slender sigmoid megaseta, both arising from a common basal body that is about half the length of the megaseta. Aedeagus elongate subtriangular, with weak lateral shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the middle of gonostylus, its ventral part (sternite 10) with ~10 setae on each half. Cerci medially separate for almost half of their length and with apical setae only.

Female unknown.

Discussion. Manota feminea belongs to a large group of species as defined under M. acris . Within the group M. feminea resembles M. parilis in having the apicomedial lobe dorsally on the gonocoxa short and broad. However, M. feminea is otherwise clearly distinguished, especially by 1) the smaller ventral part of hypoproct with short setae, and 2) having a row of setae mid-ventrally and mid-dorsally on its broad gonostylar lobe (in M. parilis the lobe is relatively narrower and the setae are marginal). Antennal flagellomeres in M. feminea are wider than long, while all other species of this group have flagellomeres at least as long as wide.

Etymology. The name is Latin, feminea [of women] referring to the short female-like antennal flagellomeres in the male.
