FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LX 1999 pp. 251-260 Record of four new species of Neostromboceros Rohwer from India (Hymenoptera: Selandriinae) V. Vasu and M. S. Saini Record of four new species of Neostromboceros Rohwer from India (Hymenoptera: Selandriinae) — Four species of Neostromboceros Rohwer are added new to science from India: N. micropunctatus sp. «., N. macropunctatus sp. n., N. macula tus sp. n. and N. maculipodus sp. n. These species are described and illustrated on a uniform systematic pattern. A key to the Indian species of this genus is provided. INTRODUCTION Concerned literature of this group reveals that so far this genus is recorded from the Oriental region only. Rohwer (1912) was the first to describe this genus based on Stromboceros metallica from Singapore. To this date 9 species are known from Indian faunistic limits, out of which six were described by Cameron (1888, 1899, 1902, 1907) viz. TV. rothneyi, N. caeruleiceps, N. fuscinervis, N. pilicornis, N. trifoveatus and N. basilineatus whereas, of the remaining three, one by Konow (1898) i.e. N. laevis and two by Malaise (1944) i.e. N. indobirmanus and N. speciosus. In 1919 Enderlein described the genus Stypoza taking Stypoza cyanea as its type species, but Malaise (1944) brought this genus under Neostromboceros Rohwer. Some other workers of the world such as Konow (1901, 1908), Rohwer (1912, 1916), Enslin (1912), Enderlein (1919), Takeuchi (1929), Forsius (1925, 1931, 1933), Benson (1935) and Malaise (1944) added 28 species to this genus from the Oriental region (excluding India). Malaise (1944) was the first to compile the entire scattered work on this genus in the from of a key from the Oriental region. The members of this genus can be identified as: Front wings with 2 radial and 3 or 4 cubital cells, 1st cubital crossvein frequently obliterate basal vein mostly subparallel to 1st recurrent vein anal cell without crossvein hind wings with 2 closed middle cells and always with sessile anellan cell. Frontal area somewhat roundly elevated and the frontal depression, when present, mostly surrounded by indistinct and very blunt ridges. Malar space linear to distinct. Clypeus truncate to emarginate. Antennái joint 3 mostly distinctly longer than 4 but sometimes may be equal to or shorter than the latter flagellum may be filiform, incrassinate or distinctly compressed scape longer than pedicel. Epicnemium separated from mesopleuron by fine, deep or distinct furrow. Claws with a large basal lobe and shorter, equal or frequently longer subapical tooth, placed lateral to apical one.
