Etymology. The name refers to the pale creamish colouration of the head, wings and parts of abdomen (clarus lat. = pale, clear).

Differentiation. Closely related to P. piperinus Redtenbacher, 1906 and P. horridus (Gray, 1835). From P. piperinus it can be distinguished by the paler colour of the tegmina and alae as well as the shorter mesosternum in the ♂♂, which is less than 1.5x longer than wide (more than 1.5x longer than wide in piperinus). From P. horridus it can easily be distinguished by the transverse black bands on the abdominal sternites and the much different pattern of the metasternum.

Description. ♂ (Figs. 46 b, 47 b, 48–49). Of moderate size (body length 53.0– 56.1 mm) and fairly robust for the genus, the mesonotum transverse and scarcely longer than the pronotum, the head bearing several prominent granules and abdominal terga VI–X with distinct lateral lobes. All lateral margins of body segments and all legs densely covered with long pale setae. General colouration of dorsal body surface and dorsal surface of legs pale brown or creamish white. Vertex creamish white with some black speckles. Antennae dark greyish brown. Pronotum and mesonotum creamish white. Tegmina and costal area of alae creamish white in the basal half and with dark greyish brown markings in the apical half. Tip of costal area of alae of pale creamish white with a few dark patterns. Anal area of alae transparent with fine brown veins. Ventral side of head and thorax yellowish to pale brown, metasternum with a U-shaped black band along the margins, which is interrupted in its centre. Abdominal sternites yellow, II–VIII having broad transverse black bands. Poculum flat with rounded posterior margin, dark brown at the base with yellow to orange margin. Front- and hind legs mid brown, mid legs of pale drab to white colour.
