Figs. 5 A–E
Male. Colour. Head brown, face yellow. Antenna yellowish. Clypeus and mouthparts pale yellowish. Thorax yellow, medial part of scutum and scutellum brownish. Legs yellowish with femora 2 and 3 slightly brownish apicoventrally. Wing pale brown; haltere yellow with dark brown knob. Abdominal tergites pale brown, seemingly darker medially, sternites pale yellow. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4, Fig. 5 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.1 times longer than palpomere 4. Number of strong postocular setae 9. Thorax. Anepisternum setose, with 52 setae; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite non-setose, episternum 3 setose, with 8 setae. Legs. Mid and hind tibial organs absent. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 not extending to the level of the tip of R1; wing length 1.9 mm. Hypopygium. Figs. 5 B–E: Sternite 9 laterally fused with gonocoxa except near the posterior margin, posterior margin concave, extending to middle of gonocoxa, anterior margin deeply incised. The few setae on sternite 9 are similar to the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa angled; ventral setae of gonocoxa unmodified. Posterolateral part of gonocoxa is drawn into an attenuating lobe; most of the setae of the lobe are arising from small ridge-like formations. Parastylar lobe membranous, covered by the gonocoxa, with one seta. No paraapodemal lobe observable. Dorsal mesial margin of gonocoxa simple. Two juxtagonostylar setae are arising from a common basal body, which is a little shorter than the setae. The ventral juxtagonostylar seta is a pointed strong megaseta while the dorsal one is an apically flattened and expanded megaseta with a whip-like branch. Anteriorly from the juxtagonostylar megasetae there is a plate-like lobe with a long strong megaseta anteriorly and with two thinner but equally long megasetae posteriorly. Posteriorly from the juxtagonostylar megasetae there are no prominent setae deviating from the other setosity. Otherwise the dorsal setae of gonocoxa are similar to those on the ventral side. Gonostylus in dorsal and ventral view narrow, scytheshaped, with 1–2 setae on lateral side and 3 setae on mesial side. Aedeagus elongate subtriangular, without lateral shoulders, with straight sides, the apex curved ventrad. Hypoproct extending posteriorly to level of base of gonostyli, the number of ventral setae (sternite 10) ca. 20 on each half. Cerci mesially separate.
Female. Unknown.
Discussion. By 1) non-setose anterior basalare, 2) non-setose laterotergite, 3) long posterolateral lobes of the gonocoxa, 4) by having lateral margin of sternite 9 largely fused with the gonocoxa and 5) by having 1+2 megasetae anteriorly from the juxtagonostylar megasetae on the dorsal side of the of the gonocoxa, Manota aristata is similar to M. rotundistylus. However, the latter has branches of the dorsal juxtagonostylar megaseta of unequal length and the gonostylus apically rounded in contrast to equally long branches of the dorsal juxtagonostylar megaseta and apically tapering gonostylus in M. aristata (cf. Figs. 5 B, E, Jaschhof & Hippa 2005: fig 25). Manota aristata is also somewhat similar to M. acutistylus, M. planistylus, M. intermedia and M. rectolobata but these species have the megasetae on the dorsal mesial margin of gonocoxa shorter including 3–4 of them in the posterior group while M. aristata has the megasetae on the dorsal mesial margin of gonocoxa longer including 2 of them in the posterior group.
Etymology. The name is Latin, aristata, with awn, referring to the narrow branch of the dorsal juxtagonostylar megasetae.
