Figs 25–26

Diagnosis

Propodeum with pair of distinctly large and finger-shaped tubercles latero-posteriorly (Fig. 26I); vein 1-SR+M strongly concave (Fig. 26G); vein r 0.9× shorter than vein r-m (Fig. 26G); mandible more robust and inner tooth of mandible longer, 0.5× as long as apical tooth (Fig. 26D); length of fore wing 5.5 mm (Fig. 26G); scutellum densely and rather finely reticulate and matt (Fig. 26H); temple rugulose and matt (Fig. 26C); hind tarsus white (Fig. 26F); metasoma black except first tergite orange brown (Fig. 26J).

Etymology

Named after a pair of distinctly finger-shaped tuberculate corners of the propodeum postero-laterally; ‘ digitus ’ is Latin for ‘finger’.
