Name

Selenops arikok Crews, 2011 sp. n.Wikispecies linkZooBank linkPensoft Profile

Type material

Holotype female: near Gran Tonel in valley Rooi Coashati, Arikok National Park, Aruba, 12°29.356'N, 69°55.461'W, ~96 m, 16.X.2004, S. Crews, F. Franken, under bark, SCC04_045, (EME sel_068).

Other material examined

ARUBA: Bringamosa, house of R. Croes, 12°29.547'N, 69°58.077'W, 14.X.2004, S. Crews, under rocks, with egg sacs, SCC04_041, 1♀, 1 imm. (CAS sel_069-070); Luela, shooting range, 12°29.023'N, 69°57.778'W, ~30 m, 15.X.2004, S. Crews, under piece of wood, SCC04_044, 1 imm. (EME sel_072).

Etymology

The specific epithet refers to the type locality, Arikok National Park, and should be treated as a noun in apposition.

Diagnosis

This species is most similar to Selenops curazao and Selenops isopodus, but can be distinguished by the more quadrangular and more hyaline median field than Selenops curazao, and unlike Selenops isopodus, the median field is not completely enclosed anteriorly. The shape of the epigynal plate and the internal copulatory organs also differ significantly (Figs 1–2). Males unknown.

Remarks

Even though only two adult female specimens have been collected, some variation is seen in the shape of border of the median field of the epigynum. In the holotype it is wider anteriorly, and more quadrangular in general, while in the other specimen, the median field is more rounded, and not wider anteriorly than it is posteriorly.
