YEMEN : SANA’ A GOV.: 2 JJ, 1 spec. , Sana’a city, Bait Baws, 15°16.3ʹN , 44°12.1ʹE , 2410 m , tank, 6.xi.2010 , J. Hájek leg. ( NMPC ). Habitat. It was collected in muddy littoral of a tank ( Fig. 5 ). Distribution. Species widely distributed in eastern and south-eastern Africa (cf. BISTRÖM 1988 ). Another species – Uvarus occultus ( Sharp, 1882 ) – was described from Saudi Arabia, and may represent its junior synonym. However the single known specimen of U. occultus differs from U. peringueyi in slightly bigger and broader body and in almost uniformly ferruginous colouration of the dorsal surface ( HÁJEK & BISTRÖM 2009 ). First record from Yemen .
