Treatment

Rhadinodontoides nov.gen.

Type species: Rhadinodontoides rufiventris nov.sp.

D e s c r i p t i o n: ♀: Flagellum slightly lanceolate. Temple moderately and roundly narrowed behind eye. Clypeus rather large, moderately convex; apical margin sharp, rounded. Malar space about as long as width of mandibular base. Mandible slender and pointed apically, lower tooth not visible. Genal carina reaching hypostomal carina away from mandibular base. Collar without median keel. Epomia present. Notaulus impressed in frontal ¼ of mesoscutum. Scutellum moderately elevated, with lateral carina in basal half. Propodeum with elongate spiracles. Area basalis without distinct median tubercle. Area superomedia pentagonal; anterior transverse carina absent. Apical transverse carina without lateral apophyses. Hind coxa densely punctate, with apico-ventral scopa. Claws with rather long teeth in basal half. Areolet pentagonal; Vein 1cu-a postfurcal by 2× its width. Nervellus of hind wing slightly reclivous, intercepted in apical 0.7.

Metasoma strongly oxypygous. 2 nd to 4 th sternites with median folds. Postpetiolus without distinct dorsal carina, median field c. 2× wider than lateral fields, with longitudinal rugae and striae. Gastrocoelus distinctly impressed, with irregular ridges. Thyridium slightly oblique, very large, 2.0× wider than the interval. Ovipositor sheath widely reaching behind metasomal apex.

R e m a r k: This new genus resembles Rhadinodonta SZEPLIGETI and Monontos UCHIDA due to the apparently unidentate mandible. It differs by the striate postpetiolus, partly carinate scutellum, pectinate claws and very large thyridium. In the key for East Palaearctic Ichneumoninae ( TOWNES et al. 1965) its runs to Hymenura TOWNES , but differs by the different and unmodified structure of apical tergites and the pectination of claws.
