Distribution. Western Atlantic: southeastern coast of United States (North Carolina to Florida), Gulf of Mexico, Caribbean Sea, to Santa Catarina, Brazil. Depth: 11 to 1020 m.
Color ( Fig. 1 View FIGURE 1. A E). Shield, pleon, and fourth and fifth pereopods light orange. Ocular peduncles white with dark orange band basally. Right cheliped with coloration on dorsal (outer) surface of chela variable: white with dark orange band on dactyl and fixed finger, or white dark orange along midportion of palm from bases of fingers to proximal palm ridge; proximal surface of chela dark orange; merus and carpus white with prominent dark orange patches on dorsal, lateral and mesial surfaces. Left cheliped: chela white with dark orange proximally; merus and carpus white with wide dark orange band. Ambulatory legs (second and third pereopods): dactyl white with light orange proximal portion; propodus white with dark distal orange band; carpus white with distal and proximal dark orange bands.
Remarks. Although Pylopagurus discoidalis has been abundantly reported in the temperate to tropical western Atlantic (McLaughlin & Lemaitre 2001, 2003), its southern limit of distribution was previously known to be near the Equator, off the coast of Amapá, Brazil. The extent of the southernmost limit of this species was only recently discovered by Nucci & Melo (2011), who reported specimens from Amapá to Santa Catarina, Brazil. The materials reported herein from off Rio Janeiro, add more records of this species from its southern limits, and confirms that this species is common along almost the entire Brazilian coast.
The coloration of Pylopagurus discoidalis has been documented almost exclusively based on specimens that have retained color patterns after preservation. Until the present report, no photographs of live specimens of this species were available. The remarkable color photograph included herein ( Fig. 1 View FIGURE 1. A E), was taken of three specimens inhabiting scaphopod shells, collected in Curaçao during a Curasub dive and brought to the surface where they were kept alive in aquaria.
