Other material examined.

JAMAICA: St. Catherine Parish: same data as types, 2♀, 4 imm. (IJNHM sel_376-380, 382). St. Thomas Parish: near 12 mile Bull Bay on left side of road, heading east, 17°55'32.5" N, 76°38'31.0" W, ~118 m, 5.VI.2006, S. Crews, I. Wilmot, under bark, SCC06_034, 1♀, 2♂, 2 imm. (CAS sel_387-391).

Etymology.

This species is named in honor of the Wilmot family for their hospitality and preservation and expansion of Jamaican culture. It is to be treated as a noun in apposition.

Diagnosis.

Females can be differentiated from other species by the sinuous margin and epigynal pockets (Figs 103-104) and males can be separated from other species by the conductor and thornlike medial branch of the RTA (Figs 105-106).

Natural History.

This species has been found in dry forests under bark of Bursera , sea grape and on tree trunks at night. The female guards the white, disc-shaped egg sac. One female made an egg sac before 5.VI.2006, and spiderlings hatched, but stayed in the egg sac until 17.VI.2006. One was observed attacking a termite and then rejecting it. A pseudoscorpion was also found inside of an abandoned egg sac (Fig. 188)

Distribution.

Endemic to Jamaica and known from the southeast coast (Map 11).
