Manota afra sp. n.

Figs 4 A–D

Male. Colour. Head brown, face paler brown. Antenna brown. Mouthparts pale yellowish. Thorax brown. Legs pale yellowish, femur 2 slightly infuscated ventrally at base, femur 3 faintly infuscated ventrally at base and on all of the apical third. 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. 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. 1.3 times longer than palpomere 4. Number of strong postocular setae 8–9. Thorax. Anepisternum setose, with 37–40 setae; anterior basalare non-setose; preepisternum 2 setose, with ca. 9 setae; laterotergite non-setose, episternum 3 setose, with ca. 11 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 1.5 mm. Hypopygium, Figs 4 B–D: Sternite 9 nearly as long as the ventral length of gonocoxa, lateral margin sharply delimited, posterior margin transverse, slightly concave, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, convex. Parastylar lobe subtriangular with 3 tranverse setae at the anterior end. Paraapodemal lobe narrow, exposed in ventral view. Dorsal mesial margin of gonocoxa simple, convex, slightly lobe-like widened on posterior part, posterior margin simple, at the posteromesial angle with a setose thumb-like lobe. Three juxtagonostylar setae present, all megaseta-like; the ventralmost one strongly sigmoid and arising from a separate basal body which is nearly half the length of the megaseta; the two more dorsal ones curved, one with a hooked apex, both arising from a common basal body which is slightly more than half the length of the megasetae. Gonostylus slightly less than the ventral length of gonocoxa, pear-shaped, broadening from base to apex, with a dorsolateral crest, at apicomesial margin with a row of six long megasetae; the setae on the ventral side similar to those of the ventral side of the gonocoxa, the dorsal side largely non-setose, laterodorsally with four long setae deviating from other gonostylar setosity. Aedeagus subtriangular, with weak lateral shoulders, the apex curved ventrad. Hypoproct posteriorly extending to the basal part of gonostylus, the ventral setae forming a mesial longitudinal row of ca. 4 setae on each half. Cerci medially separate, the apical part narrowed and curved laterad, the setae short, the longest ones as long as the subapical width of cercus.

Female unknown.

Discussion. Manota afra is unique among hitherto described Manota species by having three juxtagonostylar megasetae instead of one or two. In addition, the row of large apical megasetae of the gonostylus easily distinguishes the species even under a stereomicroscope.

Etymology. The name is Latin, afra , African, referring to the African type locality.
