Enochrus (Lumetus) cf. quadrinotatus (Guillebeau, 1896)

Material examined. Oman, Wadi Muqshin, 19°35′07″N 54°53′03″E, 108 m, iv.2011, S. Carranza leg.: 1 ♁ 1 ♀ (♁ used for DNA extraction, voucher No. IBE-RA490/IBE-RA553, sequences published in ARRIBAS et al. 2014; PALLARÉS et al. 2017).

Notes. Species new for the Arabian Peninsula. The studied specimens were tentatively identified as E. quadrinotatus in ARRIBAS et al. (2014) and PALLARÉS et al. (2017), described from Syria, although it would be necessary to study the type material of this species to confirm the identification.According to the molecular data the species belongs to the E. bicolor complex, being sister to a clade including E. falcarius Hebauer, 1991 , E. segmentinotatus (Kuwert, 1888) , E. risii Arribas & Millán, 2013 and E. cf. turanicus Schödl, 1998 ( PALLARÉS et al. 2017). The male genitalia and external morphology are clearly different from E. sinuatus d’Orchymont, 1937 (see SCHÖDL 1998) which was recorded from the UAE by FIKÁČEK et al. (2010).
