Before this study, 83 species in the genus ''{{Taxon name|Megischus}}'' were known worldwide, of which 3 species were known from China. In this paper, these three species of the genus are listed from China. A key to species of the genus ''{{Taxon name|Megischus}}'' from China is as follows:

''{{Taxon name|Megischus}}'' specimens are still poorly collected. The known diversity in China compared with the diversity outside China is low and higher numbers of species can be expected.

Taxonavigation

Ordo: Hymenoptera
Familia: Stephanidae

Name

Megischus Brullé, 1846 – Wikispecies link – Pensoft Profile

Diagnosis

Medium to large size. Temple without pale yellowish streak behind eye. Pronotum robust without transverse protuberance. First subdiscal cell of fore wing comparatively narrow basally, approximately as wide as first discal cell or narrower; vein 1-SR of fore wing differentiated with first discal cell present because of presence of vein 1-SR+M; vein 1-M and vein 2-SR straight or nearly so. Hind wing without trace of vein cu-a. Hind coxa without dorsal tooth; hind femur with two distinct teeth; hind tibia narrowed basally and inner side usually with wide sub-medical depression, evenly rounded ventrally and without oblique striae or rugae on the outer sides; hind tarsus with three tarsomeres. Sternite I not differentiated from tergite I. Tergite I 4.2–17.6 × as long as its apical width, cylindrical, distinctly longer than tergite II; tergite II more or less petiolate and sculptured basally. Ovipositor sheath with ivory subapical band.

Distribution

Cosmopolitan. The distribution of Chinese species is illustrated in Fig. 20.

Note

Megischus specimens are still poorly collected. The known diversity in China compared with the diversity outside China is low and higher numbers of species can be expected.
