198 NATURA SOMOGYIENSIS Individual variations. In some specimens, spots above antennae become confluent and form a V-shaped pattern (Fig. 2). In some females, large white spots placed on both sides of triangular membraneous patch of propodeum. Area behind cecnhri, very narrow hind margin of mesothorax may also be white. Females similar to males (Fig. 1). Number of serrulae: 14, serrulae in Fig. 8C. Sawshetah in Figs 9C and 9F. This species is unique in genus Eusunoxa Enslin 1911, since there is no other species with purple and blue metallic luster (SMITH and SAINI 2003, WEI 1997a) but only few undescribed Chinese species (Wei, pers. comm.). In the oriental revision of Smith and SAINI (2003) this species runs to Eusunoxa semipunctata Smith and Saini, 2003. E. semipunctata has head and thorax without any metallic lustre furtheremore females has orange thorax and abdomen. The male and female are very different, male has black head and thorax, female has black head but orange thorax. The new species has head black with strong bluish and violet metallic lustre and the female is similar to the male. The specific name refers for the metallic iridescence of head and thorax. Edenticornia albotriangularis spec. nov. (Figs. 3, 8B, 9A, 9D and 10A) Material.— Holotype, female. (RMNH: " S. Vietnam, Dak Lak, Chu Yang Sin N. P., nr dam 840-940 m, Mai. Traps., 2-10. vi. 2007, C. van Achterberg and R. de Vires"). Female (Fig. 3). Head black (withouth bluish or metallic lustre) including palpi and mandible. Clypeus and labrum white. Antenna black, scape with narrow white ring. Thorax black, white: dorsal margin of pronotum, parapterum and cenchri. Coxae, femora and tarsi entirely black. Trochanters white, tibiae white with longitudinal, apically widening black line from base to apex of tibiae. Abdomen black, first tergite (propodeum) with wide apical white margin (about l/3x as wide as length of propodeum), second abdominal tergite with large white triangle standing on hind margin and reaching anterior margin, 3rd tergite with small white triangle reaching middle of segment, 7-9 tergites with white, longitudinal, wide spot forming a continuous central band on these segments. Stigma, costa, subcosta and venation dark brown, wings subinfumate. Head densely and moderaterly deeply punctured all over (including frons, temples and vertex), moderately shiny. Supraantennal pits missing, frontal area not marked. Postoccipital carina visible only behind genae. Malar space extremly narrow, linear. Head narrowed behind eyes. Clypeus widely and very slightly emarginated, clypeal emargination about 0.2x as deep as clypeal median length. Ratio of antennal segments: 10 : 8 : 29 : 25 : 20 : 15 : 12 : 11 : 13. OOL : POL : OCL: 12:7:21. Vertex longer than wide as 4: 3. Eyes large, inner margins straight and parallel. Mesonotum densely, moderately deeply punctured, moderately shiny. Mesoscutellum moderately densely and moderately deeply punctured, shiny. Mesoscutellar appendage smooth and shiny. Metascutellum shiny with few, moderately deep punctures. Mesopleuron finely and very densely punctured, matt. Mesosternum with small, dense punctures, shiny. Abdominal tergites 1-3 smooth and shiny, others with fine coriaceous surface sculpture, shiny. Ratio of hind tarsal segments: 33 : 13:7:3:9. Inner tooth of claws smaller than apical (Fig. 10A). Number of serrulae 9. Each serrulae with one outstanding large tooth. Serrulae 4-6 in Fig. 8B. Sawsheath in Figs. 9A and 9D. Length: 8.0 mm. Six species are known in this genus, namely, Edenticornia birmana Malaise, 1944, E. formosana Malaise, 1944, E. megaocuh Wei, 2005, E. tibialis Wei, 1997 and E. zhejian-
