Type material.

Holotype female: ranger's station at entrance to Loma de Isabel, Puerto Plata, Dominican Republic, 19°46'41.9"N, 70°42'01.1"W, 7.X.2006, ~96 m, on S. Crews, trees at night, under bark, SCC06_068 (EME sel_606).

Other material examined.

DOMINICAN REPUBLIC: Puerto Plata: same data as holotype, 2♀, 3. imm. (MNHNSD sel_598, CAS sel_600-601, 603-605).

Etymology.

This species is named in honor of Kelvin Guerrero for all of his work on the biodiversity of arthropods of the Dominican Republic, and is to be treated as a noun in apposition.

Diagnosis.

This species is most similar to Selenops baweka sp. n., but can be separated having the genital opening nearly straight, differently shaped spermathecae, and a very small posterodorsal fold (Figs 137-138). Males unknown.
