Figs 18 A–D
Male. Colour. Head brown. Antenna brown. Mouthparts paler yellowish. Thorax brown, preepisternum 2 ventrally pale. Legs pale yellowish, trochanters 2 and 3 brown, basal third of femur 2 indistinctly infuscated, apical third of femur 3 (femur 3 lacking in the holotype) infuscated. Wing pale brownish; haltere pale brown with dark brown knob. Abdomen brown, sternites paler than tergites. All setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 18 A. Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 4 apically expanded curved sensilla; palpomere 4 with parasegment, palpomere 5 ca. 1.6 times longer than palpomere 4. Number of strong postocular setae 10. Thorax. Anepisternum setose, with 36–51 setae; anterior basalare setose, with 5–9 setae; preepisternum 2 nonsetose; laterotergite setose, with 20–29 setae; episternum 3 setose, with 9–26 setae. Legs. Mid and hind tibial organs absent. Wing. R1meeting C well on the basal half of the costal margin; the sclerotized part of M2 basally extending to the level of the tip of R1, wing length 1.8 mm. Hypopygium, Figs 18 B–D: Sternite 9 as long as the ventral length of gonocoxa, laterally fused with gonocoxa except for a short posterior part, posterior margin convex, anterior margin without a medial incision, the setae similar to ventral setae of gonocoxa. Parastylar lobe submembranous, transversely oval, with 1–2 setae at posterior margin. Paraapodemal lobe not identifiable. Dorsal mesial margin of gonocoxa simple, mostly membranous, forming a curved largely non-setose lobe with the lateral margin; at the mesial side of this lobe there is a crescent-shaped laterally setose lobe with a row of 6–7 flat scalelike megasetae at the mesial margin. At the dorsal mesial margin of gonocoxa, on more ventral level, a plate-like submembranous lobe bearing an additional more sclerotized lobe with three megasetae of which two are horizontal, one directed ventrad. One juxtagonostylar seta present, this is a flattened apically expanded megaseta arising from a curved basal body, which is about four times longer than the megaseta. Gonostylus slightly less than half of the ventral length of gonocoxa, subtriangular, widening from base to apex, the ventral side setose, dorsal side almost non-setose, apical and mesial marginal area each with three stronger setae deviating from the other setosity. Aedeagus with a broad basal part and narrow extremely elongated apical part, no lateral shoulders, the apex curved ventrad. Hypoproct large, posteriorly extending beyond the apex of gonostylus, the ventral setae scattered, indistinctly divided into a more anterior and more posterior groups, totally ca. 50 on each half. Cerci mesially separate, the setae distributed through the whole length of cercus, the longest setae about five times longer than the subapical width of cercus, nearly as long as the gonostylus.
Female unknown.
Discussion. Manota pinnulata belongs to a group of species together with M. bracteata, M. cultrigera, M. foliolata and M. pinnata (see discussion under M. bracteata). Within the group, M. pinnulata resembles particularly M. cultrigera but can be distinguished as follows: 1) in M. pinnulata has three megasetae on the lobe at the dorsal mesial margin of the gonocoxa, two horizontal and one directed ventrad, while M. cultrigera has four megasetae, all horizontal, 2) the parastylar lobe is simple, while in M. cultrigera it has a knife-like mesially directed part, and 3) the sternite 9 has a tongue-like lobe posteriorly, while in M. cultrigera the posterior margin of sternite 9 is simple and slightly concave (Hippa 2008: Fig. 3).
Etymology. The name is Latin, pinnulata, with small leaflets, referring to the row of leaflet-like megasetae posterodorsally on the gonocoxa.
