Manota burundiensis sp. n.

Figs 1 A–C

Male. Colour. Head brown, face somewhat paler. Antenna brown, including scape and pedicel. Clypeus and mouthparts pale yellowish. Thorax light brown to brown. Legs yellowish to light brown, apical half of hind femur, and apical and basal thirds of mid femur infuscated. Wing with light brownish tinge because of microtrichia; halter yellowish with blackish knob. Abdomen brown, tergites laterally and sternites lighter. All vestiture pale, yellowish or brownish, thicker setae and trichia seeming darker than finer ones. Head. Antennal flagellomere 4 ca. 1.7 times as long as wide. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4 apically curved sensilla; palpomere 4 with parasegment. Nine strong postocular setae. Thorax. Anepisternum with 68 setae; anterior basalare and laterotergite non-setose; preepisternum 2 with 25 setae; metepisternum with 17 setae. Legs. Mid and hind tibial organs absent. Wing. R 1 meeting C within basal half of costal margin; sclerotized part of M 2 not extending to level of tip of R 1; wing length 2.3 mm. Hypopygium ( Figs 1 A–C). Sternite 9 narrow, about two times as long as wide, posterior ¾ laterally free from gonocoxa, anterior ¼ fused with gonocoxa, posterior margin with deep V-shaped incision medially, extending over middle between bases of gonocoxa and gonostylus, anterior margin with a deep V-shaped incision medially, anterior half non-setose, setae on posterior half similar to those on ventral side of gonocoxa. Ventral medial margin of gonocoxa angular. Parastylar lobe large, plate-like, medially drawn out to a finger like process, which has two strong setae apically. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa simple, slightly bulging medially. Dorsal posterior margin simple, forming together with medial margin an acute angle with a dense aggregation of fine setae on medial side. On ventral side of dorsal posterior margin of gonocoxa a finger-like lobe bearing two strong apical setae. Two juxtagonostylar setae present, a normal seta and apically curved simple megaseta, both arising from a common basal body, which is about as long as the megaseta. Gonostylus subcircular, setose, setae similar to those on gonocoxa except for conspicuously long setae along apical margin; apicomedially with a small lobe bearing two dorsally turned megasetae at apex. Aedeagus subtriangular, with lateral shoulders, apex curved ventrad. Hypoproct extending posteriorly over basal part of gonostylus, the ventral setae strong and forming a mesial longitudinal stripe of 7–8 setae on each half. Cerci medially separated; setae delimited on the apical half of cercus.

Female. Unknown.

Etymology. The species is named after its occurrence in the state of Burundi by adding the Latin suffix –ensis [denoting place].

Comments. Manota burundiensis sp. n. belongs to a group of six Afrotropical species as defined under M. triseta . Among them, M. burundiensis is most similar to M. relicina (see Hippa & Kurina 2012: fig. 20) as both species have the cercal setae short and delimited on the apical half of cercus, and the gonostylus with an apical or subapical medial lobe bearing two simple megasetae. It differs in having (1) one juxtagonostylar seta as a normal seta (both juxtagonostylar setae are megasetae in M. relicina ), (2) the common basal body of the juxtagonostylar setae is about as long as setae (the basal body is considerably longer than juxtagonostylar megasetae in M. relicina ), (3) parastylar lobe with two unusually strong setae at medial corner (with normal setae in M. relicina ), (4) gonostylus apically rounded (apically transverse in M. relicina ), and (5) dorsal posterior margin of the gonocoxa forming together with medial margin an acute angle with a dense aggregation of fine setae on medial side (with a row of closely placed setae in M. relicina ).
