Manota kibaleensis sp.n.

Figs 13 A–D

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, extreme base and apical third of femur 3 infuscated, extreme base of tibia 2, in some specimens the infuscation very faint and difficult to observe. Wing brownish; 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. 13 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 50–74 setae; anterior basalare non-setose; preepisternum 2 setose, with 9–20 setae; laterotergite non-setose; 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 1.7–2.0 mm. Hypopygium, Figs 13 B–D: Sternite 9 slightly more than half of the length of gonocoxa, very broad, lateral margin sharply delimited, posterior margin transverse, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, shallowly concave. Parastylar lobe subquadrangular, subtriangular or sickle-shaped depending on the angle of view, with 4–5 setae at the anterior end. Paraapodemal lobe distinct, exposed in ventral view. Dorsal mesial margin of gonocoxa simple, posterior margin oblique, laterally drawn into a long lobe bearing numerous sharp megasetae; at the angle between mesial and posterior margins there is a setose bipartite lobe on a mere ventral level. Two juxtagonostylar setae present, both are similar slender megasetae with slightly expanded rounded apex, and arising from separate low basal bodies which are less than half the length of the megasetae. Gonostylus about half the ventral length of gonocoxa, divided into broader basal and narrower apical part, ventral setae similar to those on gonocoxa, the mesial margin of the basal part with close set of short setae, the dorsal side of gonostylus with only a few short setae at the middle. Aedeagus subtriangular, with weak lateral shoulders, the apex curved ventrad, aedeagal apodemes unusual, directed posterolaterad. Hypoproct posteriorly extending to the middle of gonostylus, the ventral setae forming a mesial longitudinal stripe of ca. 15 setae on each half. Cerci medially separate, simple, the setae placed on the apical part, short, the longest ones only slightly longer that the width of cercus.

Female unknown.

Discussion. Manota kibaleensis is similar to M. clurina and M. ephippiata but is easily distinguished from them, as well as from any other described Manota , by having numerous sharp megasetae at the apex of the posterolateral lobe of the gonocoxa. By this character the species is easily recognizable even in alcohol material under a stereomicroscope. Also the gonostylus is easily distinguishable from that of M. clurina and M. ephippiata : the basomesial lobe is very broad, occupying about the basal half of the gonostylus length, while in the other species it is a narrow appendix at the basomesial corner of the gonostylus.

Etymology. The name is derived by the Latin suffix – ensis from the name of the Kibale National Park where the type locality is situated.
