| Popis: | Pachycheles crassus (A. Milne-Edwards, 1869) Porcellana (Pachycheles) crassa A. Milne-Edwards 1869: 128, pl. 26, fig. 12. Pachycheles crassus.��� Haig 1957b: 5; Haig 1960: 141, fig. 4, pl. 31, fig. 1; Haig 1968: 57, 68; Gore 1982: 8; Werding & Haig 1982: 65. Material examined. None. Previous records from Panama. A. Milne-Edwards (1869); Haig (1960); Gore (1982). Distribution. East Pacific: Mexico, Panama (Panama Canal area, Las Perlas Is.) and Colombia (Haig 1960; Gore 1982). Ecology. Intertidal and shallow subtidal, presently known depth range: 0���8 m; typically in crevices of rocks and coralline algae (Haig 1960; Gore 1982). Remarks. Pachycheles crassus resembles the western Atlantic P. ackleianus in having the carapace transversely elongate; the P1coarsely granular; the telson composed of five plates; and the pleon without pleopods in males. However, in P. ackleianus, the P1 are less swollen than in P. crassus and possess a distinct tubercle near the base of the pollex (absent in P. crassus); the granules of the P1 tend to form longitudinal rows instead of being evenly distributed as in P. crassus; and the P2���P4 meri are covered with scattered setae, whilst being mostly glabrous in P. crassus (Haig 1960).
