Manota wittei sp. n.

Figs 1 (location E), 6 A–E

Male. Colour. Head brown, face somewhat paler. Antenna light brown. Clypeus light brown, mouthparts pale yellowish. Thorax pale brown, medial part of scutum and scutellum seem darker. Legs yellowish, extreme base of hind coxa and apical fourth of hind femur infuscated. Wing slightly infuscated; haltere yellow with dark brown knob. Abdomen light brown, tergites seem dorsally darker. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Antennal flagellomere 4 Fig. 6 A. Palpomere 3 of maxillary palpus with apicomedial thumb-like extension, with 4 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.7 times longer than palpomere 4. Nine to eleven strong postocular setae. Thorax. Anepisternum with 67–74 setae; anterior basalare non-setose; preepisternum 2 with 16–21 setae; laterotergite non-setose; metepisternum with 29–41 setae. Legs. Mid- and hind tibial organs absent. Wing. R1 meeting C within the basal half of the costa; the sclerotized part of M2 not extending to the level of the tip of R1; wing length 2.5–2.8 mm. Hypopygium, Figs 6 B–E: Sternite 9 half the length of gonocoxite, lateral margin sharply delimited, posterior margin rounded, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxite. Ventral medial margin of gonocoxite simple, shallowly sigmoid; the ventral setosity unmodified. Parastylar lobe elongate subtriangular, with 2 setae on the anterior half. Paraapodemal lobe distinct. Dorsal medial margin of gonocoxite simple, convex. Posterolateral part forming an oblique setose lobe. On the ventral side of the latter, there is a finger-like lobe bearing three apical setae. The dorsal setosity of gonocoxite generally similar to the ventral one. Two juxtagonostylar setae present, both rather unmodified megasetae arising from a common basal body, which is longer than the megasetae. Gonostylus about one third of the length of gonocoxite, oval in outline, with a narrow apicomedial lobe that bears two strong apical setae; the ventral setae of gonostylus similar to those on gonocoxite, the lateral and apical setae conspicuously long, the dorsal side of gonostylus non-setose. Aedeagus subtriangular, with distinct lateral shoulders, the apex curved ventrad. Hypoproct extending posteriorly to the middle of gonostylus, the ventral setae (sternite 10) forming a medial longitudinal stripe of ca. 6 setae on each half. Cerci medially separate, simple, the setae confined on the apical part, the longest of them as long as the subapical width of cercus.

Female unknown.

Discussion. Following the key by Hippa & Kurina (2012), the species runs to couplet 28 because of the nonsetose laterotergite, setose preepisternum 2, and gonocoxite with a finger-like lobe posterodorsally that is situated dorsally from juxtagonostylar setae. However, all nine Afrotropical species with this lobe have one (viz. M. mabokeensis Matile , M. dissidens Hippa & Kurina , M. freerki Hippa & Kurina , M. toomasi Hippa & Kurina , M. redunca Hippa & Kurina ), or two (viz. M. comata Hippa & Kurina , M. pedicellata Hippa & Kurina , M. relicina Hippa & Kurina , M. petiolata Hippa & Kurina ) apical setae on it, while M. wittei sp. n. has three. The general outline of the gonostylus and rather unmodified juxtagonostylar setae (except in M. mabokeensis ) also groups M. wittei with the nine above species. Within the group, M. wittei sp. n. particularly resembles M. pedicellata , but can easily be distinguished by the length of the cercal setae, which are as long as the subapical width of cercus, while they are as long as the cercus itself in M. pedicellata .

Etymology. The species is named after G.F. de Witte (1897–1980), the head of the scientific exploration trips to the Upemba National Park in Congo (1946–1949).
