Phimochirus occlusus ( Henderson, 1888) View in CoL : 1 female, sl 3.6 mm ( USNM 265211 ), Caribbean Sea, British Virgin Islands, 18°40’N, 64°51’W, R/V “ Caroline ”, Johnson-Smithsonian Deep-Sea Expedition, P.

Type locality. West GoogleMaps of Tortuga Island, 10°57’N, 65°52’W, Venezuela, between 69 and 155 m.
Distribution. Bermuda, Strait of Florida, Caribbean Sea of Puerto Rico, north coast of Venezuela ( McLaughlin, 1981b), Curaçao and Brazil (off Espírito Santo, Trindade Island, this study), between 38 and 268 m.
Remarks. The specimen here reported from Trindade Island is assigned to Phimochirus , whose diagnostic characters ( McLaughlin 1981b) are readilly reconized in the Brazilian material, namely, 11 pairs of biserial gills, crista dentata of the third maxilliped with one accessory tooth, propodal rasp with one row of corneous scales ( Fig. 26F View FIGURE 26 ), presence of a well-developed preungual process ( Fig. 26F View FIGURE 26 ), and females with first pleopod paired and modified as gonopods.
Phimochirus leurocarpus superficially resembles P. occlusus ( Henderson, 1888) , from which it can be readly distinguished by the presence of a row of spines on the ventral margins of dactyls of the ambulatory legs ( Fig. 26 View FIGURE 26 B– D), such spines are absent in P. occlusus . This is the first record of P. leurocarpus from the southwestern Atlantic ( Brazil), hence extending its distribution southward to around 20°S. The species was previously known only from the type material from Straits of Florida and Venezuela, and a few additional specimens from Bermuda and Puerto Rico. Here, we also recorded a specimen from Curaçao.
