Selenops arikok Crews, 2011: 16 , figs 1–2, 177 (♀).

Type material: Holotype (designated by Crews 2011): female, 12°29.356’N, 69°55.461’W, near Gran Tonel in valley Rooi Coashati, Arikok National Park, Aruba, 16 October 2004, S. Crews, F. Franken ( EME sel_068, but see Remarks).

Other material examined. See Crews (2011).

Diagnosis. Selenops arikok can be differentiated from other members of the S. isopodus group by the copulatory ducts which extend laterally beyond the sclerotized portion of the epigynal plate after curving dorsally around the secondary spermathecae ( Fig. 23 ). Additionally, the secondary spermathecae are anterior of the primary spermathecae, whereas they are even with or posterior of them in the other species ( Figs 22, 25, 28–29 ).

Description. See Crews (2011).

Distribution. Aruba ( Fig. 60 ).

Life history and habitat preferences. Collected under rocks, bark, and debris on the ground, both near to and distant from human dwellings. The egg sac is a flat, white disc attached to the substrate and guarded by the female ( Fig. 1 ). As in other selenopids, the female lays from 25– 50 eggs. The habitat from which this species was collected is dry thornscrub ( Fig. 56 ).

Remarks. These samples are apparently misplaced. The type, as well as an immature, stated to be in EME (Crews 2011) could not currently be located. Also, a second adult female and immature stated to be in CAS (Crews 2011) cannot be located. The illustrations are derived from Crews (2011). The specimen identified as S. arikok by Galvis and Flórez (2015) is actually S. isopodus ; thus, S. arikok is endemic to Aruba. The male of this species remains unknown.
