Pachygrapsus corrugatus (von Martens, 1872) (Figures 1a–d, 14f, 15f) Grapsus ( Leptograpsus ) corrugatus von Martens, 1872: 107, pl. 4, fig. 8, 8b [type locality: Cuba]. Pachygrapsus corrugatus — Kingsley, 1880: 200 (key). — Rathbun, 1918: 252, pl. 160, fig. 4 (Cuba); 1933: 89 (Puerto Rico). — Chace & Hobbs, 1969: 167 (Virgin Is.). — Manning, 1963: 159–160 (Bahamas). — Holthuis et al. , 1980: 46 (St Paul's Rocks). — Manning & Chace, 1990: 66, fig. 43 (Ascension I.). — Melo, 1996: 452, fig. 1 (Brazil); 1998: 499 (Brazil). Type material Three females and one male in alcohol with the label " Leptograpsus corrugatus , collector Gundlach, Cuba " (ZMB 3702). These are not indicated as types but many types in this collection are not marked as such (C. O. Coleman, pers. comm.). The smallest specimen (ZMB 3702) is a male approximately 12 x 14 mm, probably the specimen that is described in von Martens (1872: 107). It is herein designated as lectotype and the remaining three females are the paralectotypes. Material Examined West Atlantic . Virgin Is. : St. Croix, on coastal rocks Judith Fancy Bay, coll. H. A. Beatty, 1935–1936, 1 ov. F. 13.6 x 15.2 mm (USNM 72340). Bahamas , Treasure I., Salt Cay, Chaplin­Bahama collection, stn 247, south shore of western tip, coll. J. C. Briggs et al ., 14 August 1955, 1 M 15.4 x 17.3 mm (USNM 122786). South Central Atlantic . Ascension I. : south of Collyer Point, intertidal rocky flat around blow­hole adjacent to Cable and Wireless Beach, hand and poison, coll. R. B. Manning, 25 May 1971, 1 M 8.6 x 10.2 mm (USNM 252325). Diagnosis Very similar to Pachygrapsus fakaravensis (see diagnosis and remarks for that species). The two species differ by the striation of the abdomen, which is less pronounced in P. corrugatus than in P. fakaravensis . Measurements: medium size; carapace of specimens examined ranging from 8.6 x 10.2 to 15.4 x 17.3 mm. For Ascension I., Manning & Chace (1990: 66) indicated a smaller cl, ranging from 3.2 to 8.5 mm. Distribution West and south central Atlantic : Brazil, Bahamas, Cuba, Puerto Rico, the Virgin Is., St. Paul's Rocks, Ascension I. Habitat Intertidal rock pools often around algae. : Published as part of Poupin, Joseph, Davie, Peter J.
