Hydroglyphus farquharensis (Scott, 1912)

Material examined. Oman, Wadi Muqshin, 19°35′07″N 54°53′03″E, 108 m, iv.2011, S. Carranza leg.: 6 spec. (1 ♀ used for DNA extraction, voucher No. IBE-RA491).

Notes. New for the Arabian Peninsula. The species was described from the Seychelles, and has been recorded (under different synonyms) from Madagascar and southern and eastern Africa ( BISTRÖM 1986). Externally the species is very similar to H. signatellus (Klug, 1834) , although the male genitalia is very characteristic ( BISTRÖM 1986). It is thus likely that some of the records of H. signatellus from the Arabian Peninsula may actually correspond to this species. The species was found in a saline source in the desert, close to the border with Saudi Arabia (S. Carranza, pers. comm. 2018).
