Axianassa jamaicensis Kensley & Heard, 1990  

( Fig. 6 View FIGURE 6 )

Axianassa jamaicensis Kensley & Heard 1990   : 566, fig. 6.

Material examined. 1 female (cl 7.3 mm), MZUSP 34098, Caribbean coast of Panama, Isla Grande, southwestern coast, subtidal sand-mud flat near sea grass beds, in burrow, 0.5–1.5 m, coll. A. Anker, J.F. Lazarus, T. Kaji, 27.iii.2015.

Description. See Kensley & Heard (1990); colour photographs are provided in Fig. 6 View FIGURE 6 .

Colouration. Creamy yellowish or pinkish, with pale reddish chromatophores arranged in a characteristic pattern on carapace and each abdominal somite; chelipeds hyaline-white with large reddish or pinkish areas, especially dorsally; inner organs pale yellow-orange ( Fig. 6 View FIGURE 6 ).

Distribution. Western Atlantic: Jamaica (Montego Bay) and Panama ( Isla Grande) ( Kensley & Heard 1990; present study).

Ecology. Intertidal and shallow subtidal (less than 1.5 m) sand flats with fine sand and mud component; in burrows in muddy sand.

Remarks. Axianassa jamaicensis   was hitherto known only from the male holotype from Montego Bay, Jamaica ( Kensley & Heard 1990). The single female from Isla Grande thus represents the second record of A.

jamaicensis   since the original description of the species and also the first record for Panama. The chelipeds of the Panamanian female are noticeably weaker ( Fig. 6 View FIGURE 6 B) compared to those of the holotype male ( Kensley & Heard 1990: fig. 6 A), a sexual dimorphism typical of most, if not all species of Axianassa   .
