DiagnosisLength 3.80-4.30 mm, width 2.82-3.00 mm. Very similar to E. lituratus in general appearance and coloration. Head, pronotum, and scutellum black. Elytra yellowish testaceous to reddish brown, with a small, black apical patch. Ventral side black, except elytral epipleura yellowish brown. Male genitalia (Figs) and life stages as illustrated.

RemarksPriscibrumus lituratus and P. uropygialis belong to a complex of very similar species. Based on cytological studies on populations from India and Pakistan, Smith (1965) supposed that in the group lituratus, certainly, and in the group uropygialis, probably, five cytogenetically different (?sibling) species occurred together, some of them differing only in subtle physiological properties expressed in somewhat different ecological suitabilities.
