Description. See Felder & Manning (1986).

Color in life. Previously reported as uniformly pink or pale red due to diffuse red chromatophores throughout body, most densely in the antennular and antennal peduncles and tail fan; chelae hyaline-white; walking legs transparent (see Anker 2011: fig. 22). Specimens from Florida closely matched this description ( Figs. 2a, b View FIGURE 2 ). The specimen reported from Panama was semi-transparent with much more diffuse, orange-tan chromatophores ( Fig. 2c, d View FIGURE 2 ). The lower density of chromatophores in this specimen is likely due to smaller body size.

Type locality. Ft. Pierce, Florida, USA .

Distribution. The Atlantic coast of USA and Caribbean Sea: Atlantic coast of Florida and Florida Keys ( Felder & Manning 1986; present study), Caribbean coasts of Panama ( Anker 2011; De Grave & Anker 2017; present study), and Venezuela ( Vera Caripe et al. 2021).

Ecology. Obligate burrow cohabitant of unknown burrowing hosts in shallow fine-sediment habitats such as seagrass flats. Vera Caripe et al. (2021) hypothesized that the large body size of this species suggests that its host is likely to be a large sized callianassid species or stomatopod, but this is yet to be confirmed.

Remarks. The specimens listed above all closely agree with the type description of F. chacei ( Felder & Manning 1986) and previously published illustrations of Panamanian specimens ( Anker 2011). The single specimen listed above from Panama is the smallest individual of this species reported to date (cl 4.3 mm), but this specimen had developed appendices masculina on the second pleopods, suggesting it is an adult.
