Taxonomie remarks -1. The species Centistes excrucians (HALIDAY, 1835) and C. nißthorax TELENGA, 1950 were transferred to the genus Ancylocentrus FOERSTER, 1862 (TOBIAS 1986a: 225). Centistes medythiae MAETÔ et NAGAI, 1985 (Japan and NE China) seems to represent rather the genus Ancylocentrus FOERSTER viewing its rugosecrenulate precoxal suture (= sternaulix); a generic character of the genus Centistes is the entirely smooth mesopleuron, i.e. sternaulix indistinct. 2. In the interpretation of the genus Centistes HALIDAY I follow TOBIAS'S (1986a) opinion who considers the taxa Ancylocentrus Foerster, 1862, Centistes s. str. and Syrrhizus FOERSTER, 1862 as independent genera contrarily to VAN ACHTERBERG'S (1985) idea of ranging the taxa indicated before as subgenera of Centistes. Centistes dilatus sp. n 6 (Figs 1-2) Description of the holotype â - Body 3.1 mm long. Head in dorsal view (Fig. 1) transverse, 1.73 times as broad as long, temple rounded and somewhat shorter than eye. Occiput weakly excavated and fully carinated. Ocelli medium sized and elliptic, distance between fore and a hind ocelli as long as greatest diameter of an ocellus, POL a bit longer than OOL. Eye in lateral view 2.3 times as high as wide, at middle height of eye temple as wide as eye, ventrally narrowing. Face transverse, one-third wider than high, inner margin of eyes parallel. Clypeus 1.8 times as wide below as high medially, its lower margin slightly convex. Pair of tentorial pits far from each other, distance between them three times as long as distance between a pit and lower margin of eye. Malar space as long as basal width of mandible. Head polished, face with disperse and very fine punctation. - Antenna longer than body, with 30 antennomeres. First flagellomere 3.5 times as long as broad, further flagellomeres gradually shortening and slightly attenuating so that penultimate flagellomere twice as long as broad, last flagellomere pointed. Mesosoma in lateral view 1.55 times as long as high. Pronope absent. Notaulix weakly depressed on declivous fore part of mesonotum. Mesonotal pit absent. Prescutellar furrow with five crenulae. Propodeum with a medio-transverse carina, rugulose to uneven, on anterior (or horizontal) part smooth, shiny. Metanotum also subrugulose-uneven, sternaulix absent, otherwise mesosoma polished. - Legs thin. Hind femur 4.4 times as long as broad medially. Hind tibia about one-fourth longer than hind tarsus, hind basitarsus as long as tarsal segments 2-4. Fore wing as long as body. Venation of wings similar to that of C. cuspidatus (HALIDAY). Pterostigma four times as long as wide, issuing radial vein from its middle; rl short, r2 weakly arched and ending rather far before tip of wing. N. bas. 2.4 times as long as n, rec, dl shorter than nervellus. Metasoma as long as mesosoma. First tergite (Fig. 2) wide, 1.68 times as long as broad at its hind end, pair of spiracles before middle of tergite, from base to spiracles clearly broadening, beyond spiracles parallel-sided, longitudinally striated, shiny. Further tergites polished. Ground colour of body blackish. Clypeus and pronotum with brownish suffusion. Scape and pedicel brown, flagellum greyish-brownish. Palpi straw yellow. Legs yellow, coxae and trochanters pale yellow, hind tibia dark fumous. Tegulae yellow. Tergites 1-2 brown, rest of metasoma blackish. Wings hyaline, pterostigma opaque brown, veins opaque brownish. 9 and host unknown. Type material - Holotype o*: Nepal, Pokhara, Joniosoni trek, Ullere valley, 2100 m, 5 August 1981. leg. P. BERON. - Holotype is deposited in the Hungarian Natural History Museum (Zoological Department), Budapest; Hym. Typ. No. 7376. Distribution - Nepal (Palaearctic Region). Etymology - The species name "dilatus" refers to the relatively wide first tergite. The new species, Centistes dilatus sp. n., is nearest to C. cuspidatus (HALIDAY, 1833) regarding their entirely yellow legs, venation of wings and thinner hind femur. The two species may be separated by the following features:
