Manota simina sp. n.

Figs 1 A–C, 22 A–D

Male. Colour. Head pale yellowish brown, vertex and dorsal part of occiput dark brown. Antenna brown, scapus, pedicellus and flagellomere 1 slightly paler than the more distal parts. Mouthparts paler yellowish. Thorax brown, posteromedial part of scutum and scutellum darker brown, anteroventral part of preepisternum 2 paler brown. Legs pale yellowish, the base of femur 2 and 3 more or less distinctly infuscated, apical third of femur 3 infuscated. Wing pale brown; haltere pale brown with dark brown knob. Abdomen brown, sternites paler than tergites. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 22 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4–5 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. 1.4 times longer than palpomere 4. Number of strong postocular setae 10–12. Thorax. Anepisternum setose, with 60–69 setae; anterior basalare non-setose; preepisternum 2 setose, with 60–69 setae; laterotergite setose, with 4–6 setae; episternum 3 setose, with ca. 20–30 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 M extending to the level of the tip of R1, wing length 1.9–2.0 mm. Hypopygium, Figs 1 C, 22 B–D: Sternite 9 slightly less than half the ventral length of gonocoxa, lateral margin sharply delimited, posterior margin rounded, confluent with the lateral margin, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, shallowly sigmoid. Parastylar lobe sickle-shaped, with ca. 10 setae at anterior end. Paraapodemal lobe distinct, exposed in ventral view. Dorsal mesial margin of gonocoxa simple, posteriorly with two lobes, a narrower more dorsal one with 3–4 strong apical setae and a broader more ventral one with numerous fine setae. Two juxtagonostylar setae present, one rather unmodified megaseta, the other apically flattened, arising from separate low basal bodies. Gonostylus large, as long as gonocoxa, flattened, very elongate oval with a bilobed expansion at basomesial angle, the ventral setae similar to those on gonocoxa, the mesial setae long and forming a conspicuous fringe, the dorsal side of gonostylus non-setose except for fine subbasal setae. Aedeagus short subtriangular, without distinct lateral shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the basal part of gonostylus, the ventral setae fine, forming a mesial longitudinal stripe of ca. 10 setae on each half. Cerci medially separate, simple, the setae confined to the apical part, the longest ones ca. twice the subapical width of cercus.

Female unknown.

Discussion. By male hypopygium Manota simina is similar to M. clurina and M. ephippiata but differs in having a setose laterotergite. It is distinguished from both by having a conspicuous fringe of long setae along the mesial and apical margin, not only along the apical margin, of the gonostylus. Further, the cercus is of the usual form, not conspicuously narrowed at apex. See also discussion under M. clurina .

Etymology. The name is Latin, simina , of apes, referring to presence of apes in the type locality.
