Manota reclinata sp. n.

Figs 1 (location B), 5 A–D

Male. Colour. Head brown, face somewhat paler. Antenna light brown, scape and pedicel somewhat darker. Clypeus yellow, mouthparts pale yellowish. Thorax dark yellow, medial part of scutum and scutellum somewhat darker. Legs yellowish, ventral part of midfemur at base and apical third of hind femur infuscated. Wing slightly infuscated; haltere yellow with dark brown knob. Abdominal segments 1 and 2 dark brown with sternites lighter. Succeeding segments with tergites dorsally brown and laterally yellow, and sternites yellow with brownish apical margins. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Antennal flagellomere 4 similar to that of M. peltigera sp. n. ( Fig. 4 A). Palpi missing in the holotype. Ten strong postocular setae. Thorax. Anepisternum with 43 setae; anterior basalare with 1 seta; preepisternum 2 with 18 setae; laterotergite non-setose; metepisternum with 25 setae. Legs. Mid- and hind tibial organs absent. Wing. R1 meeting C within the basal half of the costa; the sclerotized part of M2 hardly extending to the level of the tip of R1; wing length 2.0 mm. Hypopygium, Figs 5 A–D: Sternite 9 about half the ventral length of gonocoxite, lateral margin sharply delimited, posterior margin broad, medially deeply notched, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxite, those medially at posterior margin very long. Ventral medial margin of gonocoxite simple, sigmoid; ventral setosity of gonocoxite unmodified. Parastylar lobe elongate quadrangular, oblique, with ca. 7 setae at medial margin. Paraapodemal lobe distinct, in Fig. 5 B partly covered by the parastylar lobe. Dorsal medial margin of gonocoxite simple; posterolaterally with a short lobe with a few apical setae, which are stronger than other setae of the gonocoxite. Between the dorsal posterior margin of gonocoxite and the juxtagonostylar megasetae there is a double lobe, the dorsal part of which bears numbers of fine setae and the ventral part a row of strong curved setae. Otherwise the dorsal setosity of gonocoxite is unmodified, similar to the ventral one. Two juxtagonostylar setae present, both flattened apically rounded megasetae, arising from a long common basal body. Gonostylus large, flattened, elongate quadrangular in outline, the basomedial angle appearing as an elongated subtriangular lobe, the ventral setae similar to those on gonocoxite, the setae at the apex forming a fringe of longer more lateral and shorter more medial setae, the dorsal side of gonostylus non-setose but the basomedial lobe with an area of strong short setae. Aedeagus small, short subtriangular, without distinct lateral shoulders, the apodemes curved posteriad, the apex curved ventrad. Hypoproct posteriorly extending to the basal part of gonostylus, the ventral setae fine (sternite 10), forming a medial longitudinal stripe of ca. 20 setae on each half. Cerci medially separate, the short setae confined to the apex.

Female unknown.

Discussion. Manota reclinata sp. n. is similar to M. clurina Hippa & Kurina, 2012 , which it also runs to in the key to Afrotropical species. The species are distinguished by details of the male hypopygium. Manota reclinata sp. n. has: 1) posterior margin of sternite 9 notched (broad and transverse in M. clurina ), 2) parastylar lobe elongate quadrangular (bilobed in M. clurina ), 3) dorsal part of gonocoxite posterolaterally with a lobe bearing 5–6 very prominent setae (setae are just slightly deviating from other setosity of gonocoxite in M. clurina ), 4) the two juxtagonostylar megasetae flattened and somewhat geniculate (one of the flattened juxtagonostylar megasetae is club-shaped in M. clurina ), 5) the basomedial elongated subtriangular lobe of gonostylus as long as the basal width of gonostylus (this lobe is narrow and shorter than the basal width of gonostylus in M. clurina ) and the cerci apically evenly rounded (subapically constricted in M. clurina ).

Etymology. The name is Latin, reclinata , meaning “reclined”, referring to the juxtagonostylar megasetae, which are directed obliquely backwards, towards the base of hypopygium.
