Manota platychaeta View in CoL sp. n.

Figs 10 View FIGURE 10 A–D

Male. Colour. Head brown, face somewhat paler. Antenna light brown, scape and pedicel somewhat paler. Clypeus and mouthparts pale yellowish. Thorax yellowish to light brown. Legs yellowish, basal third of hind femur infuscat- ed. Wing with light brownish tinge because of microtrichia; halter yellowish with blackish knob. Abdomen brown to dark 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. 1.5 times as long as wide. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 apically curved sensilla; palpomere 4 subapically constricted, without parasegment; palpomere 5 ca. 1.4 times longer than palpomere 4. Eleven strong postocular setae. Thorax. Anepisternum with 63 setae; anterior basalare with 11 setae, laterotergite with 33 setae, preepisternum 2 non-setose, metepisternum with 14 setae. Legs. Mid and hind tibial organs absent. Wing. R 1 meeting C within basal half of costal margin; sclerotized part of M 2 extending to level of tip of R 1; wing length 2.2 mm. Hypopygium ( Figs 10 View FIGURE 10 A–D). Sternite 9 laterally entirely fused to gonocoxa, posterior margin broad, medially concave, lateral parts posteriorly bulging, extending to base of gonostylus, anterior margin with a V-shaped incision medially, anterior 1/3 non-setose, posterior 2/3 setose, setae similar to those on ventral side of gonocoxa but arranged more densely. Ventral medial margin of gonocoxa short, simple. Parastylar lobe finger-like, with one apical seta. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa medially bulging, ventrally from the dorsal medial margin, on more ventral level a finger-like geniculate lobe with three slender, apically pointed megasetae apically. Dorsal posterior margin simple, forming together with medial margin a posteriorly projecting finger-like lobe, with 3–4 apical setae. Setae on dorsal side of gonocoxa similar to those on ventral side. One juxtagonostylar seta present, a complex spathulate megaseta with apical membranous leaf-like lobe dorsally, arising from a prominent basal body that is longer than the seta. Gonostylus elongated subquadrangular, about 5 times as long as wide medially, setose, at medial margin a submedial hump-like lobe with 2–3 apical setae, 3 apical and 1 apicolateral setae considerably stronger and longer, deviating from other setae on gonostylus. Aedeagus elongated, subtriangular, without lateral shoulders, apex curved ventrad. Hypoproct extending posteriorly to middle of gonostylus, number of ventral setae (sternite 10) ca. 30 on each half. Cerci medially separated, setae scattered over the surface, apical setae somewhat longer, deviating from others.

Female. Unknown.

Etymology. The name is Latinized from the Greek πλατύς (platys) ‘wide/broad’ and χαίτη (chaítç) ‘bristle/seta’, referring to the broad juxtagonostylar megaseta.

Comments. Manota platychaeta sp. n. belongs to a group of 14 Afrotropical species that have setose laterotergite and anterior basalare, non-setose preepisternum 2, setae on hypoproct arranged over the whole ventral surface, and the dorsal medial margin of gonocoxa without a row of flattened megasetae posteriorly. Among these species, M. platychaeta is similar to M. styloides because the megasetae on the lobe at dorsal medial margin of gonocoxa are placed together in a group, not in a row. Manota platychaeta is distinguished e.g. by having the dorsal medial margin of gonocoxa posteriorly with a group of 3 slender megasetae (5 stout megasetae in M. styloides ) and the juxtagonostylar megaseta is spathulate with an apical membranous leaf-like lobe (apically whip-like in M. styloides ).
