Etymology.

The specific epithet refers to the indigenous name of the indigenous people that once inhabited several Caribbean islands, including the ones where this species is found. It is to be treated as a noun in apposition.

Diagnosis.

The females of Selenops kalinago sp. n. can be separated from all other species by the shape of the epigynal plate, the small, slit-like genital opening, and internally, the very long sperm ducts and small spermathecae (Figs 143-144). The males can be separated from all other species by the long, thin, finger-like median apophysis (Figs 145-146).

Remarks.

There is variation in the coloration of these species as some specimens are light and others are dark. There are also slight differences in the dorsal pattern of the abdomen.

Natural history.

This species has been collected from under the bark of Campeche, Bursera , Psidium , bay, sea grape, and other trees with loose bark in dry coastal forests from sea level to 300 m elevation (Figs 191, 204). Egg sacs are single, flat, white discs, attached under bark and guarded by the female, often with a light cocoon of silk around the female and the egg sac.

Distribution.

Known from the islands of Antigua, Guadeloupe, including Les Saintes, and Montserrat (Map 14).
