Identification

-level identification requires examination of male genitalia and specific external morphological features; a diagnostic key is available for distinguishing the seven species. The four species in the vinctus-group (P. capicolus, P. reductus, P. vinctus, and P. guttus) are particularly difficult to separate without genital dissection and detailed comparison.
