Diagnosis

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

Etymology

Named after the orange mesosoma; ‘ aurantium ’ is Latin for ‘orange’ and ‘soma’ is Greek for ‘body’.

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).
