Manota vesicaria sp. n. Figs 12 A, B, C Male. Colour. Head pale brown, frons, vertex and the dorsal part of occiput dark brown. Antennal scapus and pedicellus pale brown, flagellum darker brown. Mouthparts pale yellowish. Thorax pale brown, posterior part of scutum and all of scutellum darker brown. Legs unicolorous pale yellowish. Wing unicolorous greyishbrown; haltere yellowish-brown with dark brown knob. Abdomen brown, segments 2 and 3 apparently a little paler than the others. All the setosity pale, yellowish or brownish, the thicker setae appearing darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 12 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 5–6 apically expanded curved sensilla; palpomere 4 with parasegment. Number of strong postocular setae 10–11. Thorax. Anepisternum setose, with 41–47 setae, anterior basalare nonsetose, preepisternum 2 setose, with 12–18 setae, laterotergite non-setose, episternum 3 setose, with 12–17 setae. Wing. Length 1.7 mm. Hypopygium, Figs 12 B, C: Sternite 9 about half the length of gonocoxa, lateral margin sharply delimited, posterior margin transverse, with a shallow medial notch, anterior margin deeply incised, the setae similar to the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa simple, with an inconspicuous lobe-like convexity at the level of the paraapodemal lobe, marginal setae conspicuously longer than the more lateral setae. Parastylar lobe sickle-shaped, with two or three setae at apex. Paraapodemal lobe well exposed in ventral view, inflated. Dorsal mesial margin of gonocoxa simple, convex, subapically with a strong seta arising from a large basal body. Two juxtagonostylar setae present: both strong, sigmoid, sharp-ended megasetae arising from a common basal body which is about half the length of the megasetae. Gonostylus simple, elongate-oval, ventrally and laterally covered with unmodified long setae, dorsally largely non-setose except for a subapical tuberculate area with rather short setae, apico-mesially with a dense comb-like row of 5 long setae which differ from the other setosity. Aedeagus subtriangular, with lateral shoulders, the apical part curved ventrad. Hypoproct posteriorly reaching between the base and middle of gonostylus, with ca. 12 setae on each half, lateral in position. Cerci mesially separate. Female unknown. Discussion. M. vesicaria is similar to M. pellii. It is distinguished e.g. 1) by having an inflated globular paraapodemal lobe instead of a small flattened one; 2) by having a comb-like row of very long setae apicomesially on the gonostylus instead of having short curved setae here; and 3) by having the setae on the hypoproct placed in a lateral row or zone, not in a row at the mesial margin of each half. Etymology. The name is derived from Latin, vesica, bladder, vesicaria, having a nature of bladder, referring to the inflated paraapodemal lobes. Types. Holotype.
