Pseudoamblyteles nepalensis nov.sp. (figs 25, 36)

Holotype: ♀ " Nepal, Khumbu Khumdzung 3900 m, 17.VII.62, leg. G. Ebert u. H. Falkner " ( ZSM).

Paratypes: ♀ " Nepal, Khumbu Khumdzung 3900 m, 25.VII.62, leg. G. Ebert u. H. Falkner " ( ZSM); ♀ " Nepal, Prov. Karnali, Churta E Hochtal, 3500-3800 m, 02.VI.2007, leg. F. Creutzburg " (Erfurt); ♀ " Nepal, Umg. Gothichaur, ca. 2850 m, 29°12´10´´N 82°18´56´´E, 09.061997, Weissschale, leg. Creutzburg " ( SDEI) .

D e s c r i p t i o n: ♀: Body length 13-14 mm. Flagellum bristle-shaped, with 38-39 flagellomeres, all flagellomeres longer than wide; 1 st flagellomere 3.8-4.0x longer than wide. Head covered with long erected brownish hairs, densely and coarsely punctate. Temple long, moderately and roundly narrowed behind eye, dorsally c. 0.9x as long as eye. Distance of lateral ocellus from eye 1.2-1.6x ocellar diameter. Frons and face rugose-punctate. Clypeus densely punctate, with sharp and straight apical margin. Gena with dense punctures. Malar space length 1.1x width of mandibular base. Mandible with two teeth, lower tooth much smaller than upper one. Genal carina complete, reaching hypostomal carina far from mandibular base; both carinae low.

Mesosoma very coarsely and densely rugose-punctate, covered with brownish hairs. Mesopleuron and metapleuron coarsely rugose-punctate, sometimes with longitudinal and rugose striation, juxtacoxal carina indistinct. Scutellum moderately elevated, wider than long, with lateral carina in basal half. Area basalis with strong median tubercle. Area superomedia almost square, coarsely rugose; costula absent, Outer dentiparal edge with small blunt tooth. Hind coxa densely punctate, covered with dense brownish hairs, but without distinctly separated scopa. Hind femur 4.5-4.9x longer than wide, densely punctate, sometimes with scattered punctures in dorsal third. Claws strongly pectinate.

Areolet pentagonal, frontal distance of intercubiti 4x their width; 2 nd recurrent vein in or distal to its middle. Nervulus postfurcal (2x its width).

Metasoma amblypygous. Lateral field of postpetiolus c. 0.7x as wide as median field, median field elevated and with fine irregular aciculation or coarser striation. Gastrocoelus strongly impressed, with oblique ridges. Thyridium large, almost transversal, 1.6x wider than the interval. 2 nd tergite 1.1x wider than long, densely punctate and finely granulate, aciculate between thyridia. 3 rd tergite with superficial and dense punctures, shining. 2 nd and 3 rd sternites with strong median folds. Hypopygium with apical brush of stiff oblique hairs (as in Eutanyacra). Ovipositor sheath slightly extending behind meta-

somal apex. Colour: Black, with ± strong bluish-metallic shine. 2nd and 3rd tergites reddish, 2nd tergite

darkened in basal 1/5, in one paratype 3 rd tergite black in apical half. Coxae and trochanters black; legs otherwise reddish; hind tibia black in apical 0.1-0.2; fore and mid tarsi brownish or black, hind tarsus black. Wings slightly infuscate, pterostigma yellowish.

♂ unknown.

R e m a r k: The surface structure of the mesosoma in this new taxon is similar to Pseudoamblyteles homocerus (WESMAEL). It differs by a slenderer hind femur, reddish 2 nd and 3 rd tergites and slightly blue-metallic shine of mesosoma and metasoma.
