Xylomedes rufocoronata (Fairmaire, 1892)

( Figs 18–19 )

Published records. 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.
