DOMINICAN REPUBLIC: Independencia: La Descubierta, El Azufrada, north side of Lago Enriquillo, 18°33.751'N, 71°41.853'W, -15 m, 26.XI.2004, S. Crews under rocks along trail to lake, SCC04_084, 2♂, 1♀ (EME sel_188, 190, MNHNSD sel_189).

Diagnosis.

Females can be separated from other species by the squarish lateral lobes, the sinuous opening which extends the width of the epigynal plate, and the internal genitalic structures; the sperm ducts and spermathecae are very small and simple (Figs 151-152). Males can be distinguished from other species by the c-shaped distal end of the conductor and the ventrally projecting large MA (Figs 153-154).

Remarks.

The leg formulae are different than those given by Alayón-García (1992). This is likely due to variation, and thus attests to the problem with using leg formulae for classification purposes in this genus. This species appears to be most similar to the Cuban endemic, Selenops vinalesi, along with Selenops alemani , Selenops submaculosus , Selenops simius , and Selenops morro sp. n., the latter being the only species of the aforementioned that occurs on Hispaniola.

Natural history.

Collected from under rocks in dry forests.

Distribution.

Known only from the Dominican Republic on the island of Hispaniola (Map 13).
