Genus Sternaulopius Fischer, 1965

Sternaulopius Fischer, 1965: 311; Wharton, 2006: 317. Type species (monobasic and by original designation). Sternaulopius bisternaulicus Fischer, 1965.

Diagnosis.

Below precoxal sulcus with a distinct and sculptured second sulcus (= sternaulus; Figs 39 , 50 ); malar space largely smooth, in East Asian species deeply impressed (Figs 43 , 54 , 56 ); mandible gradually widened basally and without basal lamella; occipital carina absent medio-dorsally; medio-posterior depression of mesoscutum present as small point-like depression (Afrotropical spp.) or part of notauli and medium-sized (Asian spp.; Fig. 40 ); propodeum coarsely reticulate-rugose (Figs 45 , 51 ); dorsope of first tergite deep ( van Achterberg 1993, pl. 36) or shallow (Asian sp.; Fig. 41 ); setose part of ovipositor sheath 0.3–1.0 × as long as first tergite.

Distribution.

Palaearctic [ Japan (new record); China (Jilin)], Oriental [ China (Sichuan)] and Afrotropical ( Burundi, Cameroon, Democratic Republic of Congo, Kenya, Madagascar) regions. The European records concern Biophthora Foerster, 1863 and Sternaulopius s. str. has not yet been found in Europe.
