102 Natura Somogyiensis 2-8 with projecting tufts of black hair. Ratios of antennal segments: 9:5: 19: 20: 15: 13 : 12 : 9 : 10. Antenna as long as head and thorax combined without propodeum. Pentagonal frontal area sunken bordered by blunt ridges, clypeal emargination about 0.25x as deep as clypeal median length. Gena linear. Middle and lateral pits about as large as front ocellus. Mesonotum and mesoscutellum with shallow, sporadic punctures, shiny. Hind margin of middle mesonotal lobe with deep and moderately dense punctures. Mesoscutellar appendage with few, moderately small and deep punctures. Length of inner hind tibial spur: length of hind basitarsus: 9:31. Length: 7.9 mm. The closest relative is Denticornia sikkimensis (Malaise, 1934) having slight metallic lustre and all legs extensively white. However, the wide white band on the abdomen (tergite 3 and 4 entirely white) differs the new species from all other relatives. During genitalia dissection, the specimen fallen into part and badly destroyed. Emphystegia pseudomaculata spec. nov. (Fig. 8) Holotype: male, Laos, Hua Phan Prov., Ban Saleui, Phou Pan Mt., 20°13'30"N, 103°59'26"E, 1350-1900 m, 13. 05. 2011, leg. C. Holzschuh and locals. Head black; white: clypeus, labrum, mandibles (except brown apex). Antenna entirely black. Thorax black; hind comer of pronotum, parapteron, denchri and small middle spot in middle of mesoscutellum and that of metascutellum white; tegula brown. Coxae and trochanters white, anterior coxa with small basal, other coxae with large basal black spot. Anterior and middle femora, all tibiae fulvous. Hind femur black, basal 2/3 of hind tibia fulvous, apical third black. Wings hyaline, stigma, costa dark brown, subcosta, venation blackish brown. Abdomen black, stemite 5 with wide basal spot. Ratios of antennal segments: 12 : 5 : 22 : 30 : 30 : 24 : 20 : 15 : 19. OOL : POL : OCL: 11 : 5 : 15. Head smooth and shiny, contracted behind eyes. Antenna about as long as head, thorax and half abdomen combined. Antenna filiform. Postoccipital carina reach to half level of eye. Clypeus broadly and slightly emarginated. Clypeal emargination about 0.2x as deep as clypeal median length. Gena about 0.4x as wide as diameter of anterior ocellus. Postocellar furrow deep reaching hypothetic hind margin of head. Thorax smooth and shiny. Wings with 4 cubital cells. Hind wing without closed middle cells. Anal cell of anterior wing with oblique cross-vein. Hind wing without marginal wein. Anal cell of hind wing sessile. Inner hind tibial spur short, length of inner hind tibial spur : hind basitarsus: 10 : 4L Claws with inner tooth, shorter than apical, without basal lobe. Length: 7.6 mm. Closest relative: Isotaxonus maculatus M.S. Saini & Vasu, 2001. Differences: the internal triangular sclerotised part of penis valve is in bottom position in Isotaxonus maculatus M.S. Saini & Vasu, 2001, but it is in central position in the new species. The stem is connected to ventral margin of penis valve in straight line in the new species but this point is deeply concave Isotaxonus maculatus. (Compare Fig. 8 and Fig. 7 in Saini and Vasu 2001). Male of Isotaxonus maculatus has hind femur fulvous and tergites 2-3 dominantly, tergites 4-5 entirely fulvous. In the new species, all these parts are black. In Isotaxonus maculatus metascutellum black, in the new species with central white spot. Heptamelus kubani spec. nov. (Figs. 10, 17 and 30) Holotype: female. Laos N., 1200 m., Louang Phrabang prov., Ban Song Cha env., May 1999, Leg. V. Kuban.
