Pachycheles crassus (A. Milne-Edwards, 1869) View in CoL

Porcellana (Pachycheles) crassa A. Milne-Edwards 1869: 128 View in CoL , pl. 26, fig. 12.

Pachycheles crassus View in CoL .— 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) .
