The female is distinguished from its congeners by an appendage on the apical margin of T5 which overhangs the cavity of T6. The male is characterised by a step-like broadening of the deep emargination of T7. It shares this trait with P. deserticolum sp.n., which is distinguished by several colour traits such as a yellow preoccipital band (lateral maculations in P. wahrmanicum ) or L-shaped anterolateral yellow band on scutum (black in P. wahrmanicum ).

Female ( Figs 13-14 View Fig View Fig ). 4-6 mm. Head: Clypeus creamy white, bell-shaped, broader than long (1.5-1.6 as long as broad at the broadest point); shining and with large punctures at base, matt and with smaller punctures towards apex; clypeus somewhat retracted apically; posterior margin emarginate with dense white pubescence; broad black longitudinal band in the centre (this band not reported by Mavromoustakis from Negev material); mandible light yellow with five dark brown teeth; supraclypeal area with large punctures and shining interstices (as base of clypeus); lower paraocular area and lower half of upper paraocular area creamy white; creamy white genal stripe almost reaching mandible and upper end of eye; margins of the macula sometimes tinged with red-brown; preoccipital ridge rounded, little concave in dorsal view; antenna black, reddish-brown underneath.

Mesosoma : Scutum black, densely punctate, shining; pronotal lobe black at base, creamy white distally; high lamella; scutellum widely rounded in dorsal view, angulate in lateral view; black with creamy white posterior side; axilla black anteriorly, creamy white posteriorly.

Metasoma: Metasoma barrel-shaped to rotundiform; terga shining; discs with scattered punctures, often separat- ed by up to three puncture diameters; depression with finer and denser punctation; marginal zone impunctate and curled upwards (best seen in lateral view); marginal zone broader in the middle than laterally; T2 longer than neighbouring terga; T1-T5 each with a creamy-yellow strip nearly reaching the middle; the stripes attenuated in the middle; depressions red-brown, sometimes tinged with yellowish-brown; marginal zone brownish semi-transparent; T5 with a produced narrow and short appendage in the middle; T6 broad, creamy white with black margins, strongly depressed; apical margin truncate with a small emargination in the middle; T5 with its appendage overhanging the cavity of T6.

Male ( Figs 13-14 View Fig View Fig ). 6-8 mm. Head: Clypeus, supraclypeal area, lower paraocular area and lower part of upper paraocular area pale yellow; gena with yellow stripe not reaching mandible; apical margin of clypeus truncate; mandible pale yellow with scattered punctation, tridentate with dark brown teeth; entire face with long silvery-white pubescence nearly reaching anterior ocellus; antenna as in female.

Mesosoma : Scutum with pale yellow stripe on each side of the middle above ( Mavromoustakis 1953). This stripe is absent in material from Algeria. Yellow stripe on scutellum sometimes broken in the middle. Mesosoma otherwise as in female.

Metasoma: T1-T5 similar to female; T6 laterally bulging; T7 yellow, long with deep median emargination; anterior part of emargination U-shaped, but step-like widening of opening (see also drawing in Mavromoustakis 1954a); transparent marginal area; punctation of T7 sparse; S 3 with specialised hairs with hooked apices; apical margin of S 6 wide-angled triangular; genitalia as in Fig. 3 View Fig .

Biology. All material was collected in March and April.

Distribution ( Fig. 15 View Fig ). Hoggar Mountains in Algeria (details see under Material), Negev in Israel (Ein Gedi, 31°27’N 35°23’E, and Wadi Fukra, c. 30°57’N 35°03’E) ( Mavromoustakis 1953), and central SAudi Arabia (Riyadh region).
