description: Manota collina sp. n.
(Figs 7 A, B, C)
Male. Colour. Head brown, face slightly paler, mouthparts pale yellowish. Thorax unicolorous brown. Legs pale yellowish, paler than mouthparts, base and apex of coxa 3 and whole of trochanter 3 brown, femur 3 infuscated on apical half and on basal fourth and these infuscations diffusely connected on dorsal and ventral sides of femur (actually femur 3 can be described as brown with diffuse pale markings on basal half), tibia 3 infuscated at base; leg 2 with a reminiscent but weaker colour pattern. Wing bicolorous, the basal part pale yellowish-brown, about the apical third darker brownish, the colour pattern not very conspicuous; haltere pale brown with dark brown knob. Abdomen brown. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head (lost in holotype). Antennal flagellomere 4, Fig. 7 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 1–3 apically expanded curved sensilla; palpomere 4 with parasegment. Number of postocular setae 11. Thorax. Anepisternum setose, with 47–57 setae, anterior basalare setose, with 8–11 setae, preepisternum 2 setose, with 20–33 setae, laterotergite non-setose, episternum 3 setose, with 11–17 setae. Wing. Length 2.6 mm. Hypopygium, Figs 7 B and C: Sternite 9 about one-half of the ventral length of gonocoxa, lateral margin sharply delimited, posterior margin deeply emarginated, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa but slightly longer. Ventral mesial margin of gonocoxa simple. Parastylar lobe large, with numerous setae at mesial margin. Paraapodemal lobe distinct and well exposed in ventral view. Dorsal mesial margin of gonocoxa simple, but with a prominent setose lobe subapically. Two juxtagonostylar setae present, one of these a strong but otherwise unmodified seta, the other a strong geniculate megaseta, both arising from a basal body which is as long as the setae. Gonostylus simple, elongate-quadrangular, with rather short unmodified setae, the marginal setae on the apical half of gonostylus long. Tegmen subtriangular, with lateral shoulders, the apex straight, not bent ventrad. Hypoproct posteriorly extending near the middle of gonostylus, with some 12 setae on each half, arranged in two groups, the more mesial ones in a longitudinal row. Cerci medially separate.
Female unknown.
Discussion. M. collina is similar to M. planilobata sp. n. and M. clavulosa sp. n. It is distinguished from M. planilobata by the rounded, not angular, mesial margin of the parastylar lobe and by lacking the strong mesial setae on the gonostylus. Furthermore, the subapical lobe at the dorsal mesial margin of the gonocoxa is much larger, the plate-like lobe between this and the gonostylar apodeme, lying under the dorsal gonocoxal surface, has the setae smaller and more numerous, and the thicker one of the juxtagonostylar megasetae is geniculate. In addition, M. collina is larger in size (wing length 2.6 mm) than M. planilobata (wing length 1.7 mm) and its wing is not unicolorous yellowish-brown but has the apical third infuscated. The only other Oriental species with a bicolorous wing is M. forceps Hippa and Papp. Otherwise these two species are very dissimilar. M. collina differs from M. clavulosa by lacking very strong setae on the gonostylus, by lacking thick claw-like setae mesially on the hypoproct, by having the larger one of the juxtagonostylar megasetae geniculate, and by lacking a pair of small tooth-like projections at the apical margin of tegmen. M. collina, M. planilobata and M. clavulosa resemble M. aconcinna sp. n., M. mirifica sp. n. and M. submirifica sp. n., but have the apex of the tegmen symmetric. They also differ by having one of the juxtagonostylar megasetae conspicuously stronger than the other one.
