FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LI 1990 p. 123-126 A new genus of the family Encyrtidae from Tunisia (Hymenoptera) By Cs. THURÓCZY and V. A. TRJAPITZIN (Received January 9, 1990) ABSTRACT: A peculiar new genus and a new species of the family Encyrtidae are described from Tunisia. A remarkable character of this genus is an enlarged bilobed clypeus, vertical to the facial plane. The genus belongs to the subfamily Tetracneminae

. Encyrtidae is a big and economically important family of Chalcidoidea

. At present 211 genera and about 1280 species of encyrtida are known in the Palaearctic Region. Within the Chalcidoidea this family is comparatively well studied, so it is rather difficult to find a new genus in this zoogeographical region. For example, the famous cha^cidologist Dr. A. Hoffer (Prague), found during his three expeditions to Algeria only 2 new genera of encyrtids. So it was very interesting to discover a remarkable new genus of Encyrtidae in the collection of Hungarian Natural History Museum, Budapest. Gafsa gen.n. Female. Body (Fig.l) rather compact, not flattened. Head hypognathic (mouth directed beneath), short, compressed in anteroproximal direction. Frontovertex strongly transverse, slightly convex, its plane is almost perpendicular to the plane of facial region of the head. Anterior edge of frontovertex is somewhat rounded, hind one evenly concave, well pronounced but not sharp. Temples practically absent. Ocelli forming a strongly obtuse triangle. Eyes relatively short. Malar space (cheeks) rather long, almost straight. Genal suture present. Facial excavation very large and deep, its upper border near the anterior ocellus. Antennae inserted at the level of lower eyes' border, rather close together. Medial facial elevation keel-like, narrowing towards clypeus (Fig. 2). Clypeus unique in its structure among Encyrtidae: it is strongly developed, perpendicular to the plane of face,, and bilobed (having 2 well-pronounced teeth)(Figs 1-4). Mouth border with an lateral excavation on each side. Mandibles large, with 2 welldeveloped apical teeth. Antennae long. Scape long, linear; pedicel short, considerably shorter than the 1st funicular segment; funicle not broadening to its apex, all funicular segments longer than broad; clava only a little broader than funicle, suboval, truncated, 3-segmented (Fig.

5) . Thorax convex. Pronotum short, transverse. Mesoscutum transverse, without parapsidal linea

. Axillae narrow, their apices meeting. Scutellum moderately convex, subtriangular

, but its apex not pointed. Propodeum short. Fore wings somewhat shortened, with a broad infuscated transverse stripe in the middle. Subcostal cell moderately broad. Submarginal vein without a triangular expansion in its apical third. Marginal vein longer than broad; stigmal vein comparatively short, subsesslle, broadened at apex. Postmarginal vein well developed, not snorter than stigmal
