Male. Same as female.
Biology. Unknown.
Distribution. India (Arunachal Pradesh).
Etymology. The species is named after the type locality.
Comparative diagnosis. This new species comes close to C. (P.) gravenhorstii (Nees) in having body length less than 5 mm and yellowish legs. It differs from the latter by the following differences, 31 antennomeres and longer than body (29 antennomeres, as long as body in C. (P.) gravenhorstii ), carapace slightly narrowed apically (distinctly narrowed apically in C. (P.) gravenhorstii ).
