Acta Zoologica Hungarica 37 (1 2), pp. 1 19 (1991) A SYNOPSIS OF PERILAMPUS LATREILLE WITH DESCRIPTIONS OF NEW GENERA AND SPECIES (HYMENOPTERA, PERILAMPIDAE), II* Q. Argaman Ministry of Agriculture, Department of Plant Protection and Inspection, P. 0. Box 78, IL-50250 Bet Dagan, Israel (Received 14 November 1989) The previously published Part I. thereby completed with additional new generic diagnosis, descriptions of new species, and a checklist of the species names in alphabetic order indicating the actual generic names in brackets. Genus Pondoros gen. n Type-species: Perilampus tristis Mayr, 1905. Size of both sexes small to moderate. Head thickset, transverse, usually bulky, with sharply protuberant scrobal ridge; occasionally, however, lenticular, with the front flat and almost in one plane with anterior margin of eye; accordingly, the scrobal cavity deep or shallow. Vertex narrow, acute, to moderately flat behind median ocellus, but always with a median longitudinal furrow extending from median ocellus down on the occipital declivity up to the foramen magnum, and bottom of which dehcately transversally septate. Head without scrobal carina, scrobal ridge of vertexo-orbital type, strongly diverging and almost transversally reaching inner eye orbit just before of lateral ocellus, the ridge often hard in males of batavus-group. Ocellar triangle only moderately flattened. Adorbital sulcus of inner orbit shallow; of outer orbit deep and rather sharp, and frequently become distended as temples inflated and dilated at lower half of eye (Figs 147 148). Malar sulcus deep, as long as front margin of malar cavity. Scape of A slightly dilated and flattened on its apical half. Clava of ÿ with straight sutures, without large sensorial groove, at most a flat, ovoidal area microsetulose on last claval segment. - Middle of pro notai disc narrow, its sides moderately wide; as broad or broader than prepectal triangle; its posterior margin blade-like, its antero-lateral margin not emarginate. Prepectus entirely consolidated to lateral pronotal panel, with a large impunctate stripe contiguous from middle of prepectal triangle to the panel (Fig. 111). Inner half of scapulae polished. Scuto-scutellar groove enlarged behind, longitudinally foveolate, base of scutellum narrow to acute. Axillula triangular in shape. Propodeum with plical carina well developed, strong and complete. Mesosternum keel-shaped and with no horizontal pad in front of mid coxae (in species-group tristis), although often (in species-group batavus) the second transverse crest also present but situated high on the inesosternal declivity and not in same plane with the precoxal keel; however, occasionally (in species-group politifrons), the pad distinctly horizontal, wide and bicarinulate. Abdominal petiole transverse and provided dorsally by a scale-like tubercle. Second tergite of abdomen practically glabrous, third tergite with no microsculpture. Colouration near exclusively melanistic, very rarely slightly metallic. Remarks — As resulted from the short diagnosis of above, the genus Pondoros contains some heterogeneous elements, but I find it undesirable to subdivide them into more genera. The genus is natural otherwise, and despite * I. part in Acta Zool. Hung. 1990 36 (3—4): 189 — 263. 1 Acta Zool. Hung. 37, 1991 Akadémiai Kiadó, Budapest MAGYAR TUDOMÁNYOS AKADÉMIA
