Figs 6 A–C
Male. Colour. Head brown, face somewhat paler. Antenna light brown, including scape and pedicel. Clypeus and mouthparts pale yellowish. Thorax light brown. Legs yellowish, apical third of hind femur and basal fourth of mid femur infuscated. Wing with brownish tinge because of microtrichia; halter entirely brownish. 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 subapically constricted, without parasegment; palpomere 5 ca. 1.6–1.7 times longer than palpomere 4. 8–9 strong postocular setae. Thorax. Anepisternum with 25–26 setae; anterior basalare with 5–6 setae; laterotergite with 19 setae; preepisternum 2 non-setose; metepisternum with 20–23 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 1.6–1.7 mm. Hypopygium (Figs 6 A–C). Sternite 9 laterally fused to gonocoxa, posterior margin convex, extending over base of gonostylus, anterior margin with a narrow 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 short, simple. Parastylar lobe finger-like with one strong apical seta. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa medially simple, posteriorly drawn out into an apically rounded large lobe, covering basal third of gonostylus and bearing two subapical, medially directed megasetae: the posterior one short and pointed, the anterior one longer, with a whip-like apical part. Ventrally from dorsal medial margin of gonocoxa a large medially bulging plate-like lobe bearing a row of 6 simple and strong megasetae, 3 anteriors apically slightly tapering, 3 posteriors blunt, slightly widening apically. Two juxtagonostylar setae present, both are simple, apically pointed megasetae, arising from small separate basal bodies which are similar to normal sockets of setae. Gonostylus elongated, basal third heel-like bulging medially, with an extra-long apical seta and 8–9 longer setae along apical 2/3 of medial margin. Aedeagus elongate subtriangular, apical 2/3 almost parallel-sided, without lateral shoulders, apex curved ventrad. Hypoproct extending posteriorly to the middle of gonostylus, number of ventral setae (sternite 10) ca. 30 on each half. Cerci medially separated, setae scattered over the surface, apical setae deviating from others, longer than the subapical width of cercus.
Female. Unknown.
Etymology. The species is named after Dr. Jostein Kjaerandsen (University of Tromsø, Norway), an active student of fungus gnats’ systematics and the collector of a number of the specimens from Ghana studied in this paper.
Comments. Manota kjaerandseni sp. n. belongs to a group of 14 Afrotropical species that have (1) setose laterotergite and anterior basalare, (2) the ventral setae of the hypoproct scattered over the whole ventral surface, (3) non-setose preepisternum 2, and (4) the dorsal medial margin of gonocoxa posteriorly without a row of scale- or leaf-like megasetae. Among them, the new species is unique in having a row of 6 slender and blunt megasetae marginally on a bulging plate-like lobe at the dorsal medial margin of gonocoxa and in having the posterodorsal part of gonocoxa elongated and posteriorly rounded and with two megasetae on the medial margin.
