Description. Habitus similar to P. piguensis ( Figs. 17 –19). Length 1.12–1.57 mm. Color yellow with olive tonalities. Pubescence as for P. piguensis ( Fig. 2 ).

Head longer than P. piguensis (length/width = 1.27–1.45), constricted medially, and narrowed on the posterior part, forming a clearly visible neck ( Fig. 17 ); mouthparts similar to P. piguensis .

Pronotum (Fig. 20) transversal (length/width = 0.78–0.89), similar in shape to P. piguensis .

Elytra longer than P. piguensis (length/width = 4.01–4.19), four times longer than wide (Fig. 19); basal edge of elytral humerus almost perpendicular to median line, in form of angle of 90° (Figs. 21 and 22).
