Male

Unknown.

Host

Distribution

China (Henan, Shaanxi, Zhejiang).

Remarks

Phanerotomella atratoides sp. nov. is similar to P. atrata because of the angularly widened temple and the lateral border of the carapace in lateral view being convex. However, Phanerotomella atratoides can be distinguished from P. atrata by having a superficially punctate clypeus (distinctly punctate in the latter), POL 1.5 × as long as OD (1.0-1.1 × in the latter), OOL 3.4× as long as OD (3.9 × in the latter),

a reticulate-rugulose and matt scutellum (punctate and shiny in the latter), and the basal half of the flagellum yellowish brown and the apical half dark brown (flagellum black in the latter).
