Figs 14 A–D
Male. Colour. Head brown, face somewhat paler. Antenna including scape and pedicel brown, 4 apical flagellomeres somewhat paler. Clypeus and mouthparts yellowish. Thorax brown, medial part of scutum and scutellum somewhat darker. Legs entirely yellowish. Wing with slight smoky tinge; haltere yellow with brown knob. Abdomen light brown, medial 2/3 of tergites dark brown. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer ones. Head. Fourth antennal flagellomere 1.3 times as long as broad.
Palpal segment 3 of maxillary palpus with apicomedial thumb-like extension, with two apically curved sensilla; palpomere 4 with parasegment; palpomere 5 about 1.3 times longer than palpomere 4. Eight strong postocular setae. Thorax. Anepisternum with 37 setae; anterior basalare, preepisternum 2 and laterotergite non-setose; metepisternum with 4 setae along its margin. Legs. Mid- and hind tibial organs absent. Wing. R1 meeting C within the basal half of the costal margin; the sclerotized part of M2 extending almost to the level of the tip of R1; wing length 1.4 mm. Hypopygium. Figs 14 A–D: Sternite 9 unusually short, laterally fused with gonocoxa, the posterior margin submedially concave, medially convex, not extending to the middle between the anterior margin of gonocoxa and the base of gonostylus, anterior margin deeply incised medially, non-setose. Ventral medial margin of gonocoxa straight, simple, forming a posterolateral lobe with the lateral margin. The ventral setae of gonocoxa unmodified. Parastylar lobe absent, possibly represented by one seta at the ventral medial margin of gonocoxa. No paraapodemal lobe identifiable. Dorsal medial margin of gonocoxa simple, posteriorly forming an angled lobe with the posterior margin of gonocoxa. The dorsal setosity of gonocoxa similar to the ventral one, posteriorly at the medial margin forming a fringe deviating from the other setosity. Posteriorly at the dorsal medial margin of gonocoxa, on more ventral level with a finger-like lobe bearing an isolated seta and posteriorly an aggregation of short setae. Two juxtagonostylar setae present as unmodified setae, both arising from a common basal body that is slightly shorter than the setae. Gonostylus obovoid, with a small apicomedial lobe and weakly expressed apicoloteral lobe, the former with two long setae, the latter with four shorter setae, in addition only one subbasal medial seta. Aedeagus subtriangular, the lateral sides slightly concave, the apex curved ventrally. Hypoproct extending posteriorly to the base of gonostyli, the number of ventral setae (sternite 10) ca. 8 on each half. Cerci medially separate.
Female. Unknown.
Discussion. Manota nuda belongs to a group of many Neotropical species that have a non-setose laterotergite, the gonocoxa with a long posterolateral lobe, and sternite 9 laterally fused with the gonocoxa. Among these species, M. nuda is similar to M. calva by having a completely non-setose sternite 9. Otherwise the species are very different: in M. nuda sternite 9 is much broader than long (in M. calva longer than broad), and the gonostylus is subtriangular and not much longer than broad and is without strong medial megasetae (in M. clava several times longer than broad with 6 curved megasetae medially on the apical half). Manota nuda and M. calva are the only New Word Manota species with the non-setose sternite 9.
Etymology. The name is Latin, nuda, ‘bare or empty’, referring to the non-setose sternite 9.
