Description

Glareadessus stocki Wewalka & Biström, 1998

Published records. WEWALKA & BISTRÖM (1998); ALARIE & WEWALKA (2001) (description of the larvae).

Material examined. Loc. 2: 1 spec. (used for DNA extraction, voucher No. IBE-RA103); Loc. 5: 1 spec.; Loc. 6: 1 spec.; Loc. 8: 10 spec. (1 ♁ used for DNA extraction, voucher No. IBE-RA707); Loc. 12: 3 spec; Oman, Sayq, 23º04′32″N 57º37′42″E, 1958 m, 9.x.2005, S. Carranza, E.N. Arnold & D. Donaire leg.: 1 spec.

Notes. The species was described from material collected with Bou-Rouch water pumps in the gravelly shore of wadis, “ 75–100 cm under the surface” (WEWALKA & BISTRÖM 1998). Due to its uniformly pale colour, body shape and habitat it was considered to be a subterranean species, being even described as “stygobiont” despite the presence of well developed eyes and wings (ALARIE & WEWALKA 2001). According to our observations the species inhabits the gravelly shores of wadis, mostly in residual pools, in which it could be found on the surface or just a few centimetres below the first layers of gravel. Likely due to the temporality of these habitats the species retains good flying abilities and well developed eyes, in contrast to other species with a similar appearance and habitat in the western Mediterranean, such as Graptodytes fractus (Sharp, 1882), or some populations of G. ignotus (Mulsant & Rey, 1861).
