Key to the Oriental species of Atopotrophos

1 Scutellum forming apical tooth ( Fig. 3D, F ). Malar space rather short (0.15–0.23 × basal mandible width) ( Fig. 3B ), antenna with 33–35 flagellomeres.............................................................................. 2

– Scutellum not forming apical tooth ( Fig. 4 ). Malar space longer ( Fig. 5A ). Antenna with less than 33 flagellomeres....... 3

2 Malar space 0.23 × basal mandible width ( Fig. 7B ). Postscutellum lacking apical tooth (7D). Area basalis weakly represented by wrinkles, area superomedia 1.5 × its width ( Fig. 7E ). T1 6 × posterior width ( Fig. 7G ).................... A. spiniger

– Malar space 0.15 × basal mandible width ( Fig. 3B ). Postscutellum forming apical tooth ( Fig. 3D ). Area basalis defined by distinct carina, area superomedia 2.1 × its width ( Fig. 3E ). T1 7 × posterior width ( Fig. 3J )............ A. bubeng sp. nov.

3 Clypeal margin medially truncated............................................................ A. hunanensis

– Clypeal margin medially concave ( Fig. 5A )................................................................ 4

4 Antenna with some white flagellomeres. Frons and clypeus polished. Face and scutellum black. T1–6 mostly black with yellowish hind margins....................................................................... A. fukienensis

– Antenna lacking white flagellomeres ( Fig. 4 ). Frons and clypeus matt, finally and densely punctate ( Fig. 5A ). Face and scutellum reddish-yellow ( Fig. 5A ). T1–6 light brown ( Fig. 4 )................................................ A. chinensis
