Manota freerki sp. n.

Figs 10 A–E

Male. Colour. Head pale brown, vertex and dorsal part of occiput dark brown. Antenna brown. Mouthparts pale yellowish. Thorax brown, ventral part of preepisternum 2 paler brown. Legs pale yellowish, apical third of femur 3 infuscated. Wing pale greyish 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. 10 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. 1.3 times longer than palpomere 4. Number of strong postocular setae 9. Thorax. Anepisternum setose, with 44 setae; anterior basalare non-setose; preepisternum 2 setose, with ca. 30 setae; laterotergite non-setose; episternum 3 setose, with ca. 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 1.8 mm. Hypopygium, Figs 10 B–E: Sternite 9 half the length of gonocoxa, lateral margin sharply delimited, posterior part membranous and difficult to see in the single specimen, anterior margin deeply incised, the setae slightly weaker than the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, curved. Parastylar lobe elongate subtriangular, anteriorly slightly bilobed, with two setae on each lobe. Paraapodemal lobe distinct, exposed in ventral view. Dorsal mesial margin of gonocoxa simple, sigmoid. Dorsal posterior margin simple, forming together with the mesial margin a right angle with a comb-like row of setae on the mesial side. On the ventral side of the latter there is a finger-like lobe bearing a strong apical seta. Two juxtagonostylar setae present, one is a rather unmodified seta, the other a sigmoid megaseta, both arising from a common basal body which is about as long as the setae. Gonostylus slightly more than half the length of gonocoxa, elongate subquadrangular in outline, subapically with a mesial lobe bearing two megasetae at its apex, on the dorsal side with a lateral crest; the ventral setae of gonostylus similar to those on gonocoxa, at mesial margin and laterally longer, the dorsal side of gonostylus largely non-setose except for the lateral crest. Aedeagus subtriangular, without distinct lateral shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the basal part of gonostylus, the ventral setae strong and forming a mesial longitudinal stripe of 5–7 setae on each half. Cerci medially separate, simple, the setae extending from apex along the mesial margin to the middle of cercus, short, the longest ones twice than the subapical width of cercus.

Female unknown.

Discussion. Manota freerki is similar to M. redunca and M. toomasi and follows them in the key. Except for the characters given in the key it is distinguished from both by the setosity posteriorly at the dorsal mesial margin of gonocoxa: in M. freerki the setae are evenly long and form a conspicuous comb-like row so that their sockets touch each other, in M. redunca the setae are shorter, becoming longer posteriad and there is a distinct gap between their sockets, in M. toomasi the setae are short and placed in a group rather than in a row. Further, M. freerki differs from both by its transverse, unpointed, apex of gonostylus and by having a dorsolateral crest on it. The apicomesial lobe of the gonostylus is clearly homologous with the gonostylar apex in the two other discussed species.

Etymology. The species is named after Dr Freerk Molleman (Tartu, Estonia), who curated the Malaise trap sampling in the Kibale National Park.
