Genus Indolipa Emeljanov, 2001

Indolipa Emeljanov, 2001: 71 .

Type species: Oliarus indiensis Van Stalle, 1991 , by original designation.

Description. Body length: 5.4–8.9 mm.

Head. Vertex with angularly incised basal emargination; lateral carinae slightly elevated; subapical transverse carina various in shape, arcuate, U-shaped, angulate or almost straight, connected or not connected with apical border by two small longitudinal carinae; median longitudinal carina present, absent or only distinct at basal half of disc. Face with frons and postclypeus combined forming elongate hexagonal figure; position of maximum width of frons slightly dorsad of centre of frontoclypeal suture, the latter arched dorsally; median ocellus present but usually inconspicuous at centre of frontoclypeal suture.

Thorax. Pronotum short, with a distinct median carina and two intermediate carinae, posteriorly deeply and wide angulately emarginated in median area, curving laterally, collar-like. Mesonotum usually black with five concolorous or yellowish carinae. Tegmen without concavity at costal border, 2.7 to 3.4 times as long as broad, hyaline or translucent; granules (with or without setae) present along veins; venational pattern similar to genus Oliarus ( Figs 1 , 12 ), usually with 10 apical cells. Hind tibiae with 3–6 lateral spines. Chaetotaxy of hind tarsomere 6/5 or 7/ 5 in most species, less commonly 7–9/7. Hind tarsi without platellae.

Male genitalia. Anal segment with posterior margin forming a large retrorse, variously shaped apical lobe ( Figs 3 , 16 ). Genital styles symmetrical or nearly so, dilated apically, shaft short, excavated between base and dilated apex, with one acute or blunt tooth ( Figs 10, 11 , 21, 23 ) expanding laterally from posterior margin of excavation (basal laterodorsal angle of dilated apex of Emeljanov, 2001). Aedeagus structurally highly variable between species.

Female genitalia. Structurally variable among the included species. Posterior margin of pregenital sternite usually convex or shallowly excavated in middle, the latter bearing two small convex processes submedially. Ovipositor reduced, with first and second pair of valvulae comparatively thin, reduced in various degrees.

Distribution. China (Gansu, Tibet, Taiwan), Borneo, Burma (Rangoon), India, Malaysia, Singapore, Sri Lanka.

Remarks. This genus is recorded here for the first time from the Palaearctic Region (Gansu Province and Tibet Autonomous Region, China). Three species of Indolipa are so far known from China.
