Manota abakiga sp. n.

Figs 2 A–D

Male. Colour. Head brown, face paler brown. Antenna brown. Mouthparts paler yellowish. Thorax brown, preepisternum 2 ventrally paler. Legs pale yellowish, trochanters 2 and 3 brown, femur 2 very slightly infuscated on basal part, femur 3 infuscated on apical third, slightly so on basal fourth. 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, even black, than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 2 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3–4 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. 1.3–1.6 times longer than palpomere 4. Number of strong postocular setae 10. Thorax. Anepisternum setose, with 16–28 setae; anterior basalare setose, with 7–11 setae; preepisternum 2 setose, with 6–11 setae; laterotergite setose, with 19–27 setae; episternum 3 setose, with 8–16 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 basally extending to the level of the tip of R1, wing length 1.5–1.6 mm. Hypopygium, Figs 2 B–D: Sternite 9 slightly shorter than the ventral length of gonocoxa, laterally fused with gonocoxa, posterior margin slightly convex, anterior margin with slight medial incision, the setae similar to ventral setae of gonocoxa. Parastylar lobe submembranous, roughly subquadrangular or subtriangular, partly fused with gonocoxa, with 2–3 setae at posterior margin. Paraapodemal lobe not identifiable. Dorsal mesial margin of gonocoxa simple, partly membranous in the middle, forming a curved setose lobe with the lateral margin, with a thin non-setose lobe posteriorly at the mesial margin. At the dorsal mesial margin of gonocoxa, on more ventral level, a plate-like lobe with 3–4 blunt megasetae at its mesial margin. One juxtagonostylar seta present, which is a flattened but pointed megaseta arising from a basal body which is about half of the length of the megaseta. Gonostylus ca. one half of the ventral length of gonocoxa, elongate oval with slightly pointed apex and a small lobe laterally on the apical half, the apex with a strong seta, mesial margin subapically with two weaker setae, the lobe-like lateral part with a row of short setae deviating from other setosity, otherwise the ventral side with weak setosity, the dorsal side nonsetose. Aedeagus with a broad basal part and narrow apical part separated by lateral shoulders, the apex curved ventrad. Hypoproct large, posteriorly extending as far as the apex of gonostylus, the ventral setae scattered, ca. 20 on each half. Cerci mesially separate, the setae distributed from apex near to base, the longest ones about twice longer than the subapical width of cercus.

Female unknown.

Discussion. By its wide sternite 9 which is laterally fused with the gonocoxa, by having a large hypoproct, by lacking leaf- or scale-like megasetae posteriorly at the dorsal mesial margin of gonocoxa, by having an aggregation of three or four obliquely posteriad directed megasetae on the lobe mesially at the dorsal mesial margin of gonocoxa and by having a leaf-like juxtagonostylar megaseta Manota abakiga resembles two other Afrotropical species: M. ghanaensis and M. toroensis . It is distinguished from these e.g. by having only very slightly bilobed gonostylus and by three or four megasetae on the dorsomesial lobe of the gonocoxa instead at least of seven in case of other species. Further, M. abakiga is similar to M. senticosa , distinguished by only a few megasetae on the lobe at the dorsal mesial margin of the gonocoxa and by only one conspicuous long seta on the gonostylus instead of three.

Etymology. The name is Rukiga language, abakiga , people of the mountains, living in the surroundings of the type locality.
