Diagnosis.

Head and metasoma black, mesosoma dark green; female flagellum dark brown. Body size: 3.0-3.5 mm. Head shape in frontal view (Fig. 5A, B ) much wider than high. Head in lateral view unusually long, with distinct sulcus separating posterior eye margin from temple (Fig. 5D ). Clypeal margin (Fig. 5A, B ) truncate. Supraclypeal area (Fig. 5A, B ) transverse (more than 1.5 × as wide as high), sides not defined; in male without oval lateral impressions. Malar sulcus versus anterior margin of malar depression shorter. Frontal keels (Fig. 5A, B ) absent in female, poorly developed in male. Face between scrobes and eye (Fig. 5A, B ) smooth. Face between clypeus and eye (Fig. 5A, B ) smooth. Lateral ocellus small (OOL at least twice the largest ocellar diameter). Funicular segments in female (Fig. 5A ): most segments transverse. Male scape (Fig. 5B ) slightly widened distally; ventral pores on less than half scape length. Mesosoma (Fig. 5C ) narrow (more than 1.4 × as long as wide). Mesoscutum sculpture (Fig. 5C ) without smooth median tubercle; interspaces smaller than punctures, smooth. Scutellum hind margin (Fig. 5C ) without a double carina, without bilobed protruding projection. Prepectus (Fig. 5D ) wide, dorsal margin longer than pronotal collar; well defined anteriorly (i.e. suture with pronotum very distinct); all sides with punctures, central area smooth.

Material examined.

Austria: 1♂, " Austria inferior, Dürnstein, 1973. H. Aspock, ex Raphidia", "ex Nemeritis sp. in Raphidia ratzeburgi Brauer", "Perilampus Perilampus Bčk. ♂, Z. Bouček det. 1973" (NHMUK). Turkey : 1♀, "Prov. Bolu 75/03, Bolu-Abantsee , 950 m, 40°41'N, 31°25'E, 17.V.", "Iran-Anatolien Expedition 1975, H. & U. Aspock, H. & R. Rausch, P. Ressl ", "Perilampus Perilampus Bčk. ♀, Z.

Hosts.

Nemeritis sp. ( Hymenoptera : Ichneumonidae ) in Puncha (= Raphidia ) Puncha ratzeburgi (Brauer) ( Raphidioptera : Raphidiidae ) - new biological association. The female specimen listed above was glued near the remains of a raphidiopteran larva, but without additional information.

Distribution.

Slovakia. New to Austria and Turkey.

Comments.

Easy to distinguish from all other species due to its unusually large head (Fig. 5D ), with a conspicuous sulcus posterior to eye (Fig. 5A-C ).
