110 Natura Somogyiensis densely with shallow and moderately large punctures, moderately shiny. Frontal area marked with sharp ridges. Clypeus roundly and deeply emarginated. Clypeal emargina- tion as deep as clypeal median length. Antenna about as long as head, thorax (including propodeum) combined. Gena narrow, about half as wide as diameter of anterior ocellus. Postoccipital carina hardly developed, reaching up to half length of eye. Mesonotal lobes moderately sparsely punctured with shallow and moderately large punctures, shiny. Mesoscutellum moderately densely punctured with large, moderately deep punctures, moderately shiny. Mesoscutellar appendage smooth and shiny, metascutellum shiny with few deep and large punctures. Upper 2/3 of mesoscutellum with large, dense and deep punctures, hardly shiny, lower third shiny, with moderately sparse, moderately deep and moderately large punctures. Length of ovipositor : length of hind tibia: 44 : 54. Inner hind tibal spur : maximal apical width of hind tibia: 11:9. Subapical tooth of claws about as large as apical, claws without basal lobe (Fig. 24). Serrulae in Fig. 3. Sawsheath in Fig. 13. Length: 10.0 mm. The 2 related species, namely Taxonus alboclypea (Wei, 1997) and Taxonus albocol- linia Wei, 1998 (Wei and Nie, 1998) can easily be differentiated by genitalia (compare Fig. 1 in Wei and Nie 1998, Fig. 21b in Wei 1997a and Fig. 3). Further differences: Taxonus albocollinia Wei central part of mesoscutellum is white, central area of tergites 4-6 are brown, in the new species mesoscutellum without white spot and tergites 3-4 are entirely reddish yellow, apical part of tergite 2 is frequently reddish yellow. In Taxonus alboclypea (Wei, 1997) posterior and lateral margines of tergites 2-6 are yellowish brown, scutellum is reddish brown. In the new species, scutellum is black and tergites are as it described above. Taxonus smerinthus has complete marginal vein on hind wings even in females, clypeus is white, third antennal is segment shorter than fourth. In the new species, hind wing without marginal vein, third antennal segment is much longer than fourth, clypeus is black. Genitalia (lancets) of the 2 species is also completely different.

(Figs. 2, 12, 20 and 35) Holotype: female, Hua Phan Prov., Ban Saleui, Phou Pan Mt., 20°13'30"N, 103°59'26"E, 1350-1900 m, 15. 05. 2011, leg. C. Holzschuh and locals. Head black; labrum, clypeus, basal half of mandible, palpi and supraclypeal triangle white. Scape, pedicel and base of third antennal segment rusty brown. Antennal segments 3-6 black, 7-9 white. Thorax black, tegula, most of mesoscutellum (except narrow margins) and cenchri white. Coxae, trochanters and 4 apical segments of hind tarsus rusty white. Anterior and middle femora, anterior and middle tibiae and tarsy rusty brown. Hind femur and apical third of hind tibia black. Basal 2/3 of hind tibia and hind basitarsus rusty brown. Abdomen black, 2nd tegite except middle part and hind margines of tergites 3-5 rusty yellow, apical tergite entirely and hind margines of 2 subapical tergites white. Ovipositor entirely black. Wings hyaline. Costa, subcosta, venation blackish brown, apical third of subcosta rusty brown. Stigma black with white basal third. Ratios of antennal joints: 15 : 8 : 40 : 44 : 40 : 30 : 24 : 23 : 25. Antenna about as long as head, thorax and first 3 abdominal segments combined. Last antennal segment api- cally flattened. Head contracted behind eyes, temple as wide as length of subapical antennal segment. Clypeus deeply and trapesoidally emarginated, clypeal emargination about half as deep as clypeal median length. Clypeus deeply and densely punctured. Gena about 2/3x as wide as diameter of front ocellus. Temples and vertex with moder-
