Recurvidris glabriceps

Nothing is known about the biology of .

Identification
Zhou (2001) - Resembles Recurvidris pickburni, but differs from the latter in the following characters: 1) head smooth and shining, not reticulate; 2) Petiole with a long anteroventral process; and 3) propodeal spines stout. The shape of the mandiblar teeth of the two species above can distinguish from all the known species in the Oriental and Indo-Australian regions.

Distribution based on Regional Taxon Lists
