WRANIK (2003) : 355, 449 (without precise data); GEIS (2015) : 95 (Hadiboh, wadi Ayhaft, Lahas, Nogid, wadi Fa’roh). Material examined ( 2 spec. ). YEMEN : SOCOTRA ISLAND: Wadi Es Gego, 12°28′18″N 54°00′34″E , 300 m , 13.v.2004 , 2 spec. , A. Reiter leg. ( NMPC ). Remark. Two Socotran females have been compared to abundant continental material from Tunisia , Ethiopia , Kenya , Yemen and Oman . The specimens from Socotra showed the greatest resemblance to those from Oman , but differed from all in having distinctly longer and more erect pilosity of the basal part of the pronotum and – to a lesser degree – the elytral truncation. Geographical element and distribution. Palaearctic element. Inhabitant of semi-desert areas surrounding the northeastern part of the Sahara; occurs from Tunisia through Egypt to Ethiopia and Kenya southward; and Saudi Arabia , Yemen and Oman eastward. Like in the case of Phonapate nitidipennis , it was probably introduced to Socotra with timber from nearby lands where – especially in Yemen and Oman – it is relatively common.
