( Figure 10 a-c) Philanthus coarctatus Spinola, 1839: 486 , ♀, ♂.

Diagnosis

Small species, with pale areas of body in female whitish to yellowish white ( Figure 10 (c)), and clear yellow in male ( Figure 10 (a,b)); clypeal moustache in male long, extended throughout the whole apical margin of clypeus, meeting in the middle ( Figure 10 (a)); dorsal area of propodeum smooth and shiny, with median rugose suture ( Figure 10 (b)); T3 black in both sexes, with lateral very narrow yellow streak preapically in male ( Figure 10 (b)), and irregular whitish markings in female ( Figure 10 (c)), with microsculpturing between punctures resulting in its dull appearance ( Figure 10 (b,c)).

Records from Saudi Arabia

Hofuf, Jeddah, Riyadh ( Gadallah et al. 2013), Jazan (present study).

General distribution

Chad, Ethiopia, Iran, Iraq, Israel, Italy, Jordan, Mali, Niger, North Africa, Oman, Palestine, Saudi Arabia, Sudan, Turkey, United Arab Emirates, Yemen.

Comments

Characters of this species agree with Guichard’s key (1994a, couplet 7); however, in our specimens T3 is almost black, but with small whitish spots at very postero-lateral margin in female, and very narrow yellow streak on lateral sides preapically in male. They differ from the North African specimens of de Beaumont (1949) in having T1 shiny black with two large sub-basal whitish lateral markings in female, and a large medial yellow band in male (T1 ferruginous in de Beaumont 1949).
