Figs 4 A–D
Male. Colour. Head brown, frons, vertex and dorsal part of occiput darker brown. Mouthparts pale yellowish.
Antenna brown, scapus and pedicellus concolorous with flagellum. Thorax brown, prothorax, posterolateral part of mesonotum and vetral part of mesothoracic preepisternum 2 (katepisternum) paler brown to yellowish. Legs pale yellowish, femora 2 and 3 basoventrally slightly infuscated. Wing unicolorous greyish-brown; haltere yellowishbrown with dark brown knob. Abdomen brown, sternites paler than tergites. All the setosity brownish, the thicker setae seeming darker, even black, than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 4 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. 1.2 times longer than palpomere 5. Number of strong postocular setae 11–13. Thorax. Anepisternum setose, with 29 setae, anterior basalare setose, with 10 setae, preepisternum 2 non-setose, laterotergite setose, with 26 setae, episternum 3 setose, with 7 setae. Legs. Middle tibial organ lacking. Hind tibial organ lacking. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 basally extending to the level of the tip of R1, wing length 1.8 mm. Hypopygium, Figs 4 B, C, D: Sternite 9 laterally fused with gonocoxa, extending posteriorly as far as the ventral posterior margin of gonocoxa, anterior margin with a shallow incision, the setae similar to ventral setae of gonocoxa. Parastylar lobe with a broad basal part and a narrow finger-like apical part, the latter with 7–8 scattered setae. Paraapodemal lobe not identifiable. Tergite 9 membranous, the basal margin somewhat sclerotized and discernible. Dorsal mesial margin of gonocoxa sinuous, subapically with three flattened megasetae, the basalmost one blunt, as long ad broad, the two more apical ones pointed, elongated flame-shaped. At the dorsal mesial margin of gonocoxa, on more ventral level, a plate-like lobe with ca. 10 blunt megasetae at its mesial and posterior margin. One juxtagonostylar seta present: a weakly modified megaseta arising from a basal body which is about as long as the megaseta. Gonostylus rather small, apically bilobed; the ventral side setose, the dorsal side nonsetose except for the rather short curved setae on the more dorsal one of the apical lobes, the mesial margin of the more ventral one of the apical lobes with three prominent strong setae. Aedeagus with a broad basal part and narrow attenuating apical part separated by strong lateral shoulders; the apex curved ventrad. Hypoproct large, posteriorly extending farther than the apex of gonostylus, with ca. 30 scattered setae on each half. Cerci mesially separate.
Female unknown.
Discussion. Manota omotoensis is one of the many Manota characterized by a large sternite 9 which posteriorly extends to the level of the gonostylar base and laterally is fused with the gonocoxa. Manota omotoensis is one of the species which have megasetae subapically on the dorsal mesial margin of the gonocoxa. By having three megasetae in this position M. omotoensis is similar to the Oriental M. bilobata and M. simplex Hippa, 2006 (the number varying from two to three), but in the latter two the setae are small, one third of the size in M. omotoensis and they are thickened setae rather than true megasetae. The diminishing width of the megasetae towards the apex of gonocoxa is a unique character for M. omotoensis.
Etymology. The specific epithet is derived from the name of the type locality, Omotodake, by the Latin suffix - ensis, denoting place.
