Three new Orgilus Hal. species from the IndoAustralian Region (Hymenoptera, Braconidae: Mimagathidinae) by J. PAPP, Budapest Abstract — Description of Orgilus moczari sp. n. $ from New Guinea, O. szelenyii sp. n. 9 from Australia and O. turgus sp. n. rf from Sri Lanka is given. Designation of the type-specimens of O. sumatranus (ENDERLEIN) and O. tibialis (ENDERLEIN). A key was compiled for the eight Orgilus species of the Indo-Australian Region. With 23 figures. Introduction — Up to now eight Orgilus HALIDAY species are known from the Indo-Australian Region; five species have been described previously in this century, and three species were recently discovered, their description are subsequently given. Originally Orgilus pulcher (SZÉPLIGETI) was ranged in the genus Blacus NEES, but ACHTERBERG (1976) having examined the holotype, pointed out first that this species represents the genus Orgilus HAL. Ischius leucogaster was described by HOLMGREN in 1868 from Australia (Sidney). The genus Ischius WESMAEL was synonymized with Orgilus HAL. in 1840, consequently HOLMGREN'S species was transferred into the latter genus. However, ROMAN (1910) recognized that the name Orgilus leucogaster is a simple misinterpretation of the original description and it belongs to the genus Microdus NEES within the subfamily Agathidinae. Eventually, the proper name of HOLMGREN'S species is as follows: Microdus leucogaster (HOLMGREN, 1868). Below the eight Orgilus HAL. species of the Indo-Australian Region are enumerated in alphabetical order completed with the citation of their original description : 1.

Orgilus sumatranus (ENDERLEIN), comb, n., 1912, Arch. Naturg., 78 A: 38, 9c/ (Eubadizon) — Indonesia (Sumatra). 6. Orgilus swezeyi FULLAWAY, 1956, Proc. Haw. ent. Soc, 16 (1): 41, 9 a* — Hawaii. 7. Orgilus szelenyii sp. n. 9 — Australia. 8. Orgilus turgus sp. n. rf — Sri Lanka. Orgilus moczari sp. n. 9 (Figs. 1-5) 9- Body 2.2 mm long. Head in dorsal view (Fig. 1) twice broader than long, temple behind eyes strongly rounded, occiput feebly excavated. Head in frontal view (Fig. 2) distinctly one-quarter broader than high, inner margin of eyes faintly diverging towards oral part, face also 1.5 times wider above than high. Distance between tentorial pits equals with that between one tentorial pit and nearest lower marginal point of eye. Malar space almost twice as long as basal width of mandible. Maxillar palp unusually long, in lateral view as long as height of head, filamentous; joints of labial
