ROVARTANI KÖZLEMÉNYEK XLV. 1 1984 p. KHMSO Oriental Mesitiinae (Hymenoptera: Bethylidae) By L. MÓCZÁR (Received 25 November, 1983) Abstract: Sixty-five species belonging in six genera are recorded from the Oriental territory: 2 species of Anaylax Móczár, 1 species of Incertosulcus Móczár, 4 species of Metrionotus, 3 species of Pycnomesitius

, 50 species of Sulcomesitius and 5 species of Heterocoelia Dahlbom. 4 species are known in both sexes, and 61 from only one sex. 8 species occur only in East India, 27 are found in Sri Lanka, 16 were collected in South-East India, 4 in Sundas, 5 in Philippines, 2 also in South-East India, as well as in Sundas and 1 species each partly in East India and in Palearctis (Mediterranean region), partly in South-East India and in the latter and partly in East India and in Sri Lanka. The 13 new species are Metrionotus subminimus

, M. rufohumerus

, Sulcomesitius bicolor

, S. pilosus

, S. masneri

, S. nigroalatus

, S. petersi, S. menkel, S. b re vis (each o_ ), and Sulcomesitius kibissaensis

, S. wahisi

, S. kosztarabi and Heterocoelia granulata (each $). The previously unknown female of Heterocoelia hirashimai is described. Heterocoelia hirashimai

, Sulcomesitius krombelni

, S. krombeinlcus are transferred to Pycnomesitius Móczár. The species of Mesitiinae are perhaps the most rarely collected among Bethylidae, there are only a few specimens even in the collections having otherwise very rich material. Owing to this fact, the Catalogus Hymenopterorum (DALLA-TORRE 1908) contains only 16 species from the whole world (10 American and 6 South European) and from them only 6 belong to Mesitiinae in the present sense. KIEFFER' s summarizing work (1914a) contains only 35 Mesitius species. Today 175 valid species are known. The first Oriental Mesitius species was described by MAGRETTI (1897) from Italy, which was later published by KIEFFER (1914a) also from Burma. KIEFFER described new species in 1905, 1906, 1914b and 1922 from that area and Greece, one of them was found in Afghanistan, too (MÓCZÁR 1970a). Fouts (1930) published 7 species from the area among them 3 were new.In his catalogue, KURIAN (1954) enumerated seven species that had been published by Fouts. Later KURIAN (1955) described three new species, but one of them was transferred to Cleptidae: Amiseginae subfamily (NAGY 1968). NAGY (1968) increased the number of the known species of the area by four. MÓCZÁR (1970a) classified the former Mesitius species into sex genera (4 were new) and described three new species (MÓCZÁR 1970b, 1971b). Since then the number of Oriental species has increased as a result of the elaboration of the big material of USNM (Washington) and espe-
