Type material examined: Paratype ♀ : “Paratype / Agadez, Aïr Sud, 525 m , 8.VIII / IFAN 1947, L. Chopard, A. Villiers / Lathrobium villiersi Cam. P. Type / M. Cameron Bequest B.M. 1955-147. / Pseudolathra villiersi (Cameron) , det. V. Assing 2012” ( BMNH ) . Comment: The original description of Lathrobium villiersi is based on a “Type à l’Ifan” from “Monts Tarraouaji ( 900 m . )” ( Cameron 1950 ) in the Air range in Niger . The aedeagus of the holotype was figured by Coiffait (1982b) . Additional material examined: Pakistan : 2 ♂♂ [1 slightly teneral], Baluchistan , Zhob valley , sand desert, 24.-25.VIII.2009 , leg. Gurko (cSch, cAss) ; 4 ♀♀ , Tribal Area , Sulaiman mts. , Drazinda tribal agency, 1700 m , 17.-21.VIII.2008 , leg. Gurko (cSch, cAss) . Yemen : 1 ♀ , Tihama , 3 km N Bayt al Faqih , 14°30'N , 43°13'E , 4.XI.1996 , leg. Hacker (cAss) . Diagnosis: In external characters highly similar to P. unicolor and P. himalayana ; reliably distinguished only by the male primary and secondary sexual characters: ♂ : sternite VII without distinctly modified pubescence, posterior margin almost truncate ( Fig. 25 ); sternite VIII of similar shape and chaetotaxy as in P. unicolor ( Fig. 26 ); aedeagus approximately 1.0 mm long, dorsal plate with slender and apically acute (ventral view) apical portion of distinctive shape ( Figs 27-28 ). Figs 20-28: Pseudolathra brevincisa ( 20-24 ) and P. villiersi from Pakistan ( 25-28 ): forebody ( 20 ); male sternite VIII ( 21, 26 ); aedeagus in lateral and in ventral view ( 22-23, 27-28 ); ventral process of aedeagus in ventral view ( 24 ); male sternite VII ( 25 ). Scale bars: 20: 1.0 mm; 21-28: 0.5 mm. Distribution and natural history: Pseudolathra villiersi was previously known from the Sahara and Saudi Arabia ( Coiffait 1982a , 1982b ). The above specimens from Pakistan represent a new country record and considerably expand the known distribution eastwards. The female-based record from Yemen is tentative and requires confirmation. The species appears to be adapted to arid habitats. One specimen collected in August is slightly teneral.
