Description. For detailed description and illustrations see Armstrong (1949).

Size range. Males from Panama and Aruba 3.2 mm cl and 4.0 mm cl, respectively; female from Aruba 4.2 mm cl; specimens from Jamaica, Belize and Barbados (not measured) similar in size; type specimens from the Dominican Republic in the same size range, at 2.8–3.3 mm cl ( Armstrong 1949) .

Colour in life. Body, frontal appendages, walking legs and tailfan uniform wine-red; second pereiopods pale bluish, changing to pale orange distally; major and minor chelae dark red with brown or olive-greenish tinge ( Fig. 24 View FIGURE 24 ).

Type locality. Barahona, Dominican Republic .

Distribution. Western Atlantic: Bahamas [Damas and Anguilla Cays, Cay Sal Bank]; Caribbean Sea: Dominican Republic [Barahona], Cuba [Batabanó Gulf], Belize [Carrie Bow Cay], Jamaica [Discovery Bay], Aruba, Curaçao, Panama [ Isla Grande], St. Martin, Barbados ( Armstrong 1949; Lemaitre 1984; Duffy 1992; Martínez-Iglesias et al. 1996; present study; see map in Fig. 51 View FIGURE 51 ).

Ecology. Shallow areas of coral reefs, known depth range 0.5–14 m (present material in 0.5–1.5 m); in crevices of partly eroded corals; typically in heterosexual pairs.

Remarks. Synalpheus dominicensis is the only western Atlantic species of the genus with a row of spiniform setae on the merus of the third and fourth pereiopods ( Armstrong 1949). In the field, S. dominicensis can be easily recognised by its uniform, wine-red body colour, including on the ventral side ( Fig. 24 View FIGURE 24 ). The present records from Panama, St. Martin and Barbados expand the previously known range of S. dominicensis to the southwestern, northeastern and southeastern margins of the Caribbean Sea, respectively.
