Antenna approximately 2.1 mm long and slender; antennomere III approximately 3 times as long as broad; IX distinctly oblong. Coloration of body pale-reddish.

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 mm long 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).

Eyes rather large, distinctly longer than postocular region in dorsal view. Antennae longer ( 1.4 mm ) and more slender ( Fig. 1 ); antennomere III approximately twice as long as broad; IV-V approximately 1.5 times as long as broad. Pronotum more convex in cross-section and less strongly narrowed posteriorly ( Fig. 2 ). Head and pronotum with dense punctation; interstices on average narrower than diameter of punctures ( Fig. 2 ). ♂: sternite VIII with larger and deeper posterior excision ( Fig. 4 ); aedeagus with slightly asymmetric and much less acute apex in ventral view; internal sac with large sclerotized spine ( Fig. 5 ).
