[email protected] Abstract A new species of leucospid wasp, Leucospis pulcherrima is described from Hahajima Island. This is the first record of Leucospidae from the Ogasawara Islands. Key words : Chalcidoidea, Leucospis, new species, Ogasawara Islands, Japan. Wasps of the genus Leucospis are parasitoids pronotum, the band laterally turning forward on the tube-renting or mud-doubing Aculeata, along lateral margins of pronotum but not reach- belonging mostly to bees of the family Megachil- ing frontal margin (Fig. 1); posterior 0.5 of idae and less frequently to wasps of the family scutellum, with anterior margin deeply incised Eumenidae etc. Approximately 110 species are (Fig. 3); subalar area of mesopleuron; apical 0.4 recorded primarily from warmer parts of the of outer surface of fore femur; fore tibia dorsally; world (Boucek, 1974), out of which three species apical 0.2 of mid femur; mid tibia entirely; large have been so far recorded from Japan (Habu, spots at baso-dorsal and apico-ventral parts of 1962, 1977; Yamagishi, 1989). In this paper, I hind coxa; large lunar subbasal spot and large describe a new species of the genus from the subapical spot on outer surface of hind femur Ogasawara Islands as the fourth species of Leu- (Fig. 5); large triangular mark on upper surface cospis from Japan. This is the first record of Leu- of hind tibia obliquely covering area from middle cospidae from the Ogasawara Islands.
