Diagnosis.

This species is most similar in habitus to Selenops bocacanadensis sp. n., but the females can be easily distinguished by the copulatory organs in that in Selenops insularis the genital openings occur along a small v-shaped opening (Figs 119-120). The male is most similar to Selenops trifidus , but can be distinguished by the copulatory organs in that the dorsal branch of the RTA of Selenops insularis widens distally, and is longer anteriorly, and the MA is slender throughout (Figs 121-122).

Remarks.

It is likely this species isn't established in Jamaica, as both records were from Kingston, a major shipping port, and are quite old. Recent searching in Jamaica turned up no specimens of this species. Muma (1953) mentioned that the females of this species are variable, but he did not elaborate. There is some variation in size in both males and females, but none was noticed in the copulatory organs of the many specimens examined. Muma (1953) suggested that some variants may be females of Selenops trifidus . Given the isolation of that species on Navassa Island, I believe this to be unlikely.

Natural History.

This species is very common and widespread. From historical records, it seems to travel easily on bananas. It is found under bark and rocks, in houses, on plants, often occurring in areas with other species of Selenops (Figs 189, 206). The female guards the white, disc-shaped egg sac. One egg sac had 87 eggs and never hatched. Another egg sac had 42 offspring inside.
