Type material

Holotype female: Hellshire Hills, St. Catherine Parish, Jamaica, ‘A2 Depression', (iguana site), 17°51'59.3"N, 76°57'54.0"W, ~275 m, 3.VI.2006, S. Crews, under bark, SCC06_031 (EME sel_383). Paratypes: Male, same data as holotype (EME sel_384).

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).
