Antenna approximately 2.1 mmlong and slender; antennomere III approximately 3 times as long as broad; IX distinctly oblong. Coloration of body pale-reddish. Body, particularly abdomen, with coarse and dense punctation. Sinai Peninsula( Map 1).............. .........................................................................................................  P. schatzmayri(KOCH)  - Distinctly smaller and more slender species; body length <7.0 mm; length of forebody < 2.5 mm. Antenna < 1.5 mmlong and less slender; antennomere III at most twice as long as broad; IX at least as broad as long..........................................................................2   2 Body dark-brown. Eyes small, shorter than postocular region in dorsal view (ASSING 2012: figure 11). Antenna shorter ( 1.2 mm) and less slender (ASSING 2012: figure 10); antennomere III approximately 1.5 times as long as broad; IV-V indistinctly oblong. Pronotum somewhat flattened and distinctly narrowed posteriorly (ASSING 2012: figure 11). Head and pronotum with moderately dense punctation; interstices on average broader than diameter of punctures. ♂: sternite VIII with very small posterior excision (ASSING 2012: figure 13); aedeagus symmetric and apically very acute in ventral view; internal sac without large sclerotized spine (ASSING 2012: figures 14-15). Socotra Island( Yemen) ( Map 1).....................................................................  P. socotranusASSING  - Body pale-reddish.

Pronotum more convex in cross-section and less strongly narrowed posteriorly ( Fig. 2).
