Lithodes galapagensis n. sp. (Figs 7, 8) Material examined. Galapagos Archipelago: Johnson Sea-Link II Cruise station 3101, Cabo Douglas, Fernandina Island, 00° 17 ’ 30 ”S, 091° 39 ’ 36 ”W, 17.07. 1998, 648m: male holotype, CL 114 mm; female paratype, CL 84 mm, Seymour Island, 00° 21 ’ 42 ”S, 090° 15 ’00”W, 25.07. 1998, 740 m (all USNM 1122586). Etymology. This species is named after its type locality, the Galapagos Islands. Description of the holotype. Carapace roughly pyriform in outline (Fig. 7 d); as wide as long when measured at maximal width of carapace. Dorsal regions well defined; covered uniformly with small spinules more or less acute at apex, without setae (Fig. 7 b). Gastric region convex and slightly more inflated than branchial and cardiac regions. One pair of slender spines 7 mm in length, emanating from the mid part of this region — level with hepatic spines on lateral margin. Spinules sparse on apex of gastric region and very few around base of prominent spines. Cardiac region depressed and separated from gastric region by smooth, wide, and saddle-shaped groove. Cardiac region depressed anteriorly, and more inflated posteriorly around single pair of long, slender spines in this region. A pair of acute spinules directly anterior to this pair. Triangular cardiac region separated from branchial regions by grooves which converge posteriorly, and then diverge close to the margin to describe posterior of branchial regions. Branchial regions each with single long, slender spine at apex; a few large, acute spinules posteriorly. A pair of conical spines in intestinal region almost on posterior margin. Exterior orbital spine just surpassing length of eyestalks; anterolateral spine about equal in length or slightly smaller. Hepatic spines slightly inflated at base, with long slender spine reaching 20 mm. Two spines on anterior portion of each branchial lateral margin, and several much smaller, conical spines interspersed between them and on posterolateral margins. Rostrum with long, straight median ...
