Hosts. Solitary larval entoparasitoids (koinobiont) of mainly leaf-mining moths from the genera Coleophora Hübner (Coleophoridae); Parornix Spuler, Phyllonorycter Hübner (Gracillariidae); Leucoptera Hübner, Lyonetia Hübner (Lyonetiidae); Bohemmania Stainton, Ectodemia Busck, Stigmella Schrank, Trifurcula Zeller (Nepticulidae); Tischeria Zeller (Tischeriidae); Rhopobota Lederer (Tortricidae) (Lepidoptera).
diagnosis
Diagnosis of the genus. Head weakly transverse (dorsal view). Occipital carina distinct and complete, joined below with hypostomal carina. Vertex reticulate-punctate, often with transverse striae at least posteriorly. Ocelli small, arranged in triangle with base distinctly larger than its sides. Eye with dense and long setae. Frons not or only weakly concave. Clypeal and malar sutures deep and complete. Clypeus usually straight in lower margin. Antenna relatively long, rather thickened, usually setiform. Scape long and wide, 1.5 – 2.0 × longer than its maximum width; pedicel short. First flagellomere longer than second flagellomere. Flagellomeres in apical half of antenna usually longitudinal or subsquare, rarely weakly transverse. Mesosoma relatively short. Mesoscutum densely and distinctly punctate-reticulate, high and curvedly elevated above pronotum. Prescutellar depression short, crenulate. Prepectal carina absent. Precoxal sulcus distinct, rather wide, long, sinuate, entirely crenulate. Propodeum medially with high and curved transverse carina, rarely also with areas delineated by distinct carinae, mainly wide rugulose-reticulate, sometimes almost smooth between carinae. Fore wing with large pterostigma. Radial vein (r + 3 - SR) with one or two abscissae, first abscissa (r) (if present) very short; distal 0.3 – 0.5 of radial vein desclerotised and transparent; arising from pterostigma separately from first radiomedial vein (2 - SR), however sometimes first radiomedial vein (2 - SR) arising from short first abscissa of radial vein (r) closely to pterostigma. Discoidal (discal) cell large, anteriorly usually sessile, but rarely subpetiolate near parastigma. Recurrent vein (m-cu) postfurcal to first radiomedial vein (2 - SR). Mediocubital vein (M + CU 1) distinctly curved towards longitudinal anal vein (1 - 1 A). Brachial (subdiscal) cell widely open distally; most part of second abscissa of longitudinal anal vein (2 - 1 A) and brachial vein (CU 1 b) absent. In hind wing, radial (marginal) cell widened distally, without additional transverse vein (r). First abscissa of mediocubital vein (M + CU) distinctly longer than its second abscissa (1 - M). Nervellus (cu-a) strongly desclerotised and transparent. Hind coxa elongate and wide; hind femur wide. Hind tibia distinctly clavate. Claw small and weakly curved. Metasoma depressed dorsoventrally, entirely or almost entirely smooth, with immovably fused first to third tergites, posterior tergites rather distinctly protruding behind third tergite. First tergite without dorsope and carinae. Both first sutures absent, or if sometimes present, then very fine and smooth. Ovipositor sheaths weakly widened distally.
