Figs. 5 A–D
Male. Colour. Head pale brown, vertex darker brown. Antenna brown. Mouthparts pale yellowish. Thorax brown, preepisternum ventrally paler. Legs pale yellowish, apices of of mid- and hind coxae, mid- and hind trochanters and, apical third of hind femur infuscated. Wing unicolorous pale brownish; halter pale brown with darker brown knob. Abdomen pale brown. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4 in both sides seen in ventral view and is slightly wrinkled, apparently similar to Fig. 4 A. Palpomere 3 of maxillary palpus with apicomedial thumb-like extension, with 4 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 not measurable on either side. Number of strong postocular setae 10–13. Thorax. Anepisternum with 29–32 setae; anterior basalare with 3 setae; preepisternum 2 setose, with 11 setae; laterotergite nonsetose, episternum 3 setose, with 7 setae. Legs. Midtibial organ absent. Hind tibial organ present. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 not quite extending to the level of the tip of R1; wing length 1.8 mm. Hypopygium, Figs. 5 A–D: Sternite 9 less than one-half of the ventral length of gonocoxa, lateral margins sharply delimited and convex, posterior margin transverse with a small V-shaped medial cleft, anterior margin with deep U-shaped indentation, the setae similar to the ventral setae of gonocoxa. Ventromedial margin of gonocoxa simple, convex, rather unclear medially. Parastylar lobe subtrapezoidal, transverse, with a row of 4 setae on posterior half. Paraapodemal lobe simple but large. Dorsomedial margin of gonocoxa simple, convex, posteriorly forming a rounded lobe with the posterior margin of gonocoxa and bearing three strong setae at apex. Posterior dorsal margin of gonocoxa with slight cleft but there is not any distinct lobe on its lateral side. A plate-like lobe posteriorly on gonocoxa, situated ventrally from the dorsal margin, bearing a row of 6 very strong setae on its posterior margin. Dorsal setosity of gonocoxa similar to ventral. Two juxtagonostylar setae present, both rather weakly modified curved megasetae, one with a fine hair-like apex, the other with more blunt apex, both arising from a common small basal body. Gonostylus narrow, elongate, with acute apex, ventral side setose, dorsal side nonsetose except on a tubercle at the middle of the lateral part, all the gonostylar setae unmodified, a couple of apical setae deviating from the others in being much longer. Aedeagus elongate subtriangular, without distinct lateral shoulders, the apex curved ventrally. Hypoproct extending posteriorly over the middle length of gonostylus, with two lateral lobes, the more dorsal one at the middle length, the more ventral one at posterior margin, the latter apparently belonging to sternite 10 which bears ca. 15 scattered setae on each half. Cerci medially separate, simple. Tergite 9 membranous.
Female unknown.
Discussion. In the key to Oriental and Palaearctic Manota given by Hippa (2011) M. nepalensis runs to couplet 50 leading to the eastern Palaearctic M. indahae Hippa & Kjaerandsen and the Oriental M. collina and M. subcollina. Also M. incilis, described above, is similar in this respect. Manota nepalensis differs from all in having two pairs of lateral lobes on its hypoproct (in the others only with posterolateral corners which do not appear lobelike), in having very strong setae arranged in a single transverse row at the posterior margin of the posterior lobe on the dorsomedial margin of the gonocoxa (in the latter cases not conspicuously strong, in an oblique row, and widely scattered on the ventral surface of the lobe) and by having only 4 setae on its parastylar lobe (versus many in the other species). In M. nepalensis the dorsomedial margin of the gonocoxa is drawn into a thumb-like lobe like in M. collina and M. subcollina. In M. nepalensis this lobe bears three strong setae instead of a number of very fine ones as seen in the two other species. Further, M. nepalensis differs from M. indahae in having the apex of the aedeagus bent ventrally (versus straight and directed posteriorly), from M. collina and M. subcollina by the unicolorous wing (versus pale basal part and dark apical part) and from M. incilis by the narrow elongated gonostylus which is nearly three times longer than broad (versus semicircular, ca. 1.3 times longer than broad). M. nepalensis is also similar to M. pileata recently described from Borneo (Ševčík et al. 2014) but is distinguished in having long setae at the postero-medial angle of the dorsal side of the gonocoxa instead of a group of short curved setae, and in having six long sharp setae on the plate-like lobe at the dorsomedial margin of the gonocoxa instead of three or four blunt ones.
Etymology. The specific epithet is derived by the Latin suffix - ensis, denoting place, from Nepal where the type locality is situated.
