description: Manota epigrata sp. n.
Figs 5 A, B, C, 6 A, B
Male. Colour. Head pale brown, frons, vertex and occiput darker brown, antennal flagellum slightly darker than scapus and pedicellus, mouthparts pale yellowish. Thorax pale brown, posterior part especially on dorsal side more or less extensively and intensively darker brown. Legs pale yellowish, in some specimens femora 2 and 3 with inconspicuous infuscation at base. Wing unicolorous greyish-brown; haltere yellowish-brown with dark brown knob. Abdomen brown, sternites 1–4 paler. All the setosity yellowish or brownish, the thicker setae seeming darker than the finer setae and trichia. Head. Antennal flagellomere 4, Fig. 5 A. Palpomere 3 of maxillary palpus with apicomesial extension, with 4–5 apically expanded curved sensilla; palpomere 4 with parasegment. Number of strong postocular setae 8–11. Thorax. Anepisternum setose, with 41–56 setae, anterior basalare non-setose, preepisternum 2 setose, with 18–23 setae, laterotergite non-setose, episternum 3 setose, with 8–15 setae. Wing. Length 1.7–2.1 mm. Hypopygium, Figs 5 B, C, 6 A, 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, a couple of the posterolateral setae stronger than the others. Ventral mesial margin of gonocoxa slightly sigmoid. Parastylar lobe large, with a thick transversely directed seta on mesial margin and two thinner more anterior setae arising from a small lobe. Paraapodemal lobe distinct, well exposed in ventral view. Dorsal mesial margin of gonocoxa simple except for a subapical weakly expressed setose lobe. Gonocoxa with a large apico-lateral lobe with three or four prominent setae on mesial margin. Two juxtagonostylar setae present, both being rather unmodified megasetae which are subequal in size, slightly curved and arising from a common basal body which is about half the length of the setae. Gonostylus simple, elongate, with rather short unmodified setae ventrally, apically with three or four long flattened setae, subapically on dorsal side with a slightly tuberculate area with curved setae, otherwise the dorsal side almost non-setose. Aedeagus subtriangular, short, the lateral shoulders distinct but rather weak, the apex curved ventrad. Hypoproct posteriorly scarcely reaching the middle of gonostylus, ventrally with ca. 12 setae in a longitudinal row on each half. Cerci mesially separate.
Female unknown.
Discussion. M. epigrata is similar to M. ancylonema. It is distinguished e.g. 1) by the juxtagonostylar setae which are gently curved, not geniculate, and 2) by having two setae, not only one, arising from a small secondary anterior lobe on the parastylar lobe. I previously included (Hippa 2008a) the holotype and the paratype from Doi Inthanon NP under M. ancylochaeta with the suggestion that they would belong to a different species. The more extensive material which I have now studied from several localities shows that the observed differences are quite constant. On one occasion, both species were found in the same Malaise trap catch. The three specimens listed under other material below have a small subapical lobe with a couple of long setae at the mesial margin of the gonostylus (Fig. 6 A), unlike the holotype and the paratypes (Fig. 5 B).
Etymology. The name is an artificial combination of letters to resemble a Latin adjective.
