Key to the species of phupanensis species group

1. Protibiae unidentate (Fig. 39); serration on lateral margins of pronotum poorly developed (Fig. 35); mesometasternal process weakly produced beyond mesocoxae (Fig. 38); lobes of parameres nearly rounded at apex not sharply pointed at ends in dorsal view (Fig. 44).......................... ..

– Protibiae bidentate (Figs. 29, 69); serration on lateral margins of pronotum distinctly developed (Figs. 27, 65); mesometasternal process produced beyond mesocoxae (Figs. 30, 67); lobes of parameres nearly straight at apex, slightly pointed at ends in dorsal view (Figs. 43, 70).................................................................................... 2

2. Pronotal surface sparsely setose (Fig. 65); antennal club more than 3.5 times longer than of basal segments; mesometasternal process produced beyond mesocoxae, surface with long and dense hairs posteriorly (Fig. 67); ventroapical process of parameres indistinct without protuberance on top of right paramere in lateral view (Fig. 71); parameres as in Figs 70, 71 and Keith (2008, figs. 15–16)...................................................................
