Manota ancylochaeta sp. n.

( Figs 3 A, B, C, 4 A, B)

Male. Colour. Head pale brown, frons, vertex and occiput darker brown, antennal flagellum slightly darker than scape and pedicel, mouthparts pale yellowish. Thorax pale brown, preepisternum 2 ventrally paler than other parts. Legs pale yellowish, femora 2 and 3 with inconspicuous infuscation at base. Wing unicolorous yellowish-brown; haltere yellowish-brown with dark brown knob. Abdomen pale brown. All the setosity pale, yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 3 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4–6 apically expanded curved sensilla; palpomere 4 with parasegment. Number of postocular setae 10–11. Thorax. Anepisternum setose, with 50–65 setae, anterior basalare non-setose, preepisternum 2 setose, with 11–27 setae, laterotergite non-setose, episternum 3 setose, with 15–21 setae. Wing. Length 1.8–2.0 mm. Hypopygium, Figs 3 B and C, 4 A and B: Sternite 9 about one-half of the ventral length of gonocoxa, lateral margin sharply delimited, posterior margin transverse, anterior margin deeply incised, the setae similar to the ventral setae of gonocoxa. Ventral mesial margin of gonocoxa sigmoid. Parastylar lobe large, with a thick transverselydirected seta on mesial margin and one or two thinner more anterior transverse setae arising from a small lobe. Paraapodemal lobe distinct, well exposed in ventral view. Dorsal mesial margin of gonocoxa simple except for a subapical rather weakly expressed setose lobe. Gonocoxa with a large apico-lateral lobe with a few prominent setae on mesial margin. Two juxtagonostylar setae present, both of these subequal in size, varying from slightly curved to geniculate, arising from a common basal body which is about half the length of the setae. Gonostylus simple, elongate, slightly curved, with rather short unmodified setae, apically with a few very long setae, subapically on the dorsal side with a slightly tuberculate area with short curved setae. Tegmen subtriangular, short, the lateral shoulders distinct but rather weak. Hypoproct posteriorly scarcely reaching the middle of gonostylus, with some 12 setae in a longitudinal row or zone on each half. Cerci medially separate.

Female unknown.

Discussion. The two specimens from Doi Inthanon National Park differ from the other specimens studied by having the juxtagonostylar setae slightly curved, not geniculate, and by having two setae anterobasally on the parastylar lobe instead of one. It is not impossible that they represent a separate species.

M. ancylochaeta resembles many of those Oriental species which have a non-setose laterotergite, laterally well demarcated sternite 9 and a large apicolateral mesially setose lobe on the gonocoxa, especially M. acutangula Hippa , M. calcarata Hippa , M. curvata Hippa , M. fera Hippa , M. ferrata Hippa , M. pectinata Hippa , M. procera Hippa , and M. transversa Hippa. M. ancylochaeta is distinguished from all these similar species by the stout transverse seta at the middle of the mesial margin of the parastylar lobe.
