Manota toomasi sp.n.

Figs 23 A–D

Male. Colour. Head pale brown, vertex and dorsal part of occiput dark brown. Antenna brown, scapus in some specimens slightly paler than the more distal parts. Mouthparts pale yellowish. Thorax brown, posteromedial part of scutum and scutellum darker brown, ventral part of preepisternum 2 more or less distinctly paler brown. Legs pale yellowish, apical fourth of femur 3 infuscated, the infuscation in some cases very faint and difficult to observe, traces of slight infuscation at base of F2 and F 3 in some specimens. 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. 23 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 9–11. Thorax. Anepisternum setose, with 39–80 setae; anterior basalare non-setose; preepisternum 2 setose, with 11–30 setae; laterotergite non-setose; episternum 3 setose, with ca. 19–38 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 1.8–2.2 mm. Hypopygium, Figs 23 B–D: Sternite 9 about half the length of gonocoxa, lateral margin sharply delimited, posterior margin rounded or transverse, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple. Parastylar lobe elongate subtriangular or slightly sickle-shaped, varying in appearance depending on the angle of view, with 2 setae on the anterior half, the setae arising from prominent basal bodies. Paraapodemal lobe distinct, exposed in ventral view. Dorsal mesial margin of gonocoxa simple, convex; dorsal posterior margin simple, posteromesial angle blunt, apically rounded, with an aggregation of setae. On the ventral side of the posterior margin there is a finger-like curved lobe bearing one apical seta Two juxtagonostylar setae present, both rather unmodified pointed subequal megasetae arising from a common basal body which is about as long as the longer megaseta. Gonostylus about half the length of gonocoxa, oval in outline; there is a small apicomesial lobe bearing two megasetae at apex, the lobe is usually turned to the dorsal side in the mounts; the ventral setae similar to those on gonocoxa, few of the lateral and apical setae conspicuously long, the setae along the mesial margin forming a sparse fringe of rather long setae, the dorsal side of gonostylus non-setose. Aedeagus subtriangular, without distinct lateral shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the basal part of gonostylus, the ventral setae forming a mesial longitudinal stripe of ca. 4 setae on each half. Cerci medially separate, simple, the setae confined to the apical part, short, about as long as the apical width of cercus.

Female unknown.

Discussion. Manota toomasi is similar to M. redunca and M. freerki . For further discussion, see under M. redunca and M. freerki .

Etymology. The species is named after Prof. Toomas Tammaru, Tartu, who is supervising the so-called “ Uganda project” in the Tartu University ( Estonia) and was one of the organizers of the expedition to Kibale National Park in 2010.
