Propodeum with pair of small tubercles latero-posteriorly (Fig. 10I); vein 1-SR+M slightly concave (Fig. 10G); vein r 1.3 × as long as vein r-m (Fig. 10G); mandible slender and inner tooth of mandible reduced, 0.4× apical tooth (Fig. 10D); length of fore wing 4.6 mm (Fig. 10G); scutellum largely punctate except basal reticulation and shiny (Fig. 10H); temple punctate and shiny (Fig. 10C); hind tarsus dark brown (Fig. 10F).

Distribution

China (Fujian, Guangdong, Guangxi).

Remarks

Phanerotomella aurantisoma sp. nov. is similar to P. digitata sp. nov. because of its having the antenna with a white band on 3 rd –5 th segments, mesosoma orange-brown and eye in dorsal view as long as temple. However, Phanerotomella aurantisoma can be distinguished from P. digitata by having the propodeum with a pair of small and blunt tubercles latero-posteriorly (distinctly larger and finger-shaped tubercles in the latter), a punctate and shiny scutellum (reticulate and matt in the latter), a punctate and shiny temple and face (rugulose and matt in the latter), a comparatively slender mandible and the inner tooth 0.4× as long as apical tooth (more robust and 0.5× in the latter).
