Diagnosis.

Body length 4.3-13.0 mm; antenna with 21-26 segments, without pale band and slender medially, of male with linear tyloids (= elevated elongate areas) on 10th-16th antennal segments; supra-antennal elevations smooth or punctate, without depression dorsally, remain far separated from each other medially and without horizontal “shelf” between antennal bases; temple usually punctate or reticulate-punctate and moderately shiny; occipital carina ending at hypostomal carina at level of mandibular base; vertex flattened, without median depression dorsally; apical segment of labial palp widened and obtuse, more or less triangular; mandibles wide in anterior view and sublaterally attached to head; mesoscutum and scutellum distinctly punctate or rugose; metanotum at least partly convex latero-dorsally and often sculptured; vein 1-SR of fore wing medium-sized to long; fore wing often with subapical dark patch or large part of fore wing dark brown; triangular dorso-apical part of hind trochanter separated by an oblique groove; fore trochanter subparallel-sided and distinctly longer than hind trochanter; hind tarsus slightly or not modified; propodeal foramen more or less arched dorsally and often with a lamelliform carina; second sternite convex in lateral view (but less so in males), strongly sclerotized and frequently densely punctate, sometimes with a medio-posterior elevation but without pair of small teeth; basal half of third sternite flat, without a distinct ledge anteriorly; hypopygium of female pointing anteriorly toward second sternite or straight down or pointing posteriad; body variable, often moderately robust.

Biology.

Reared as hyperparasitoid of parasitoid wasps ( Ichneumonidae and Braconidae ) and parasitoid flies ( Tachinidae ) in lepidopteran or sawfly caterpillars, but some species are primary parasitoids of Pergid sawflies in Australia ( Raff 1934; Carne 1969; He and Chen 1986; Weinstein and Austin 1995; Carmean and Kimsey 1998; He 2004).

Distribution.

China, Russia, Mongolia, India, SriLanka, Thailand, Laos, Papua New Guinea, Myanmar, Malaysia, Indonesia, Japan. Before this study, 20 species of this genus have been described from China, with eight recorded from Yunnan. We describe here two species new to science from Yunnan. Until now, four species in this genus were only found in Yunnan.
