MaxCL ovigerous female: 4.14 mm. MaxCL non-ovigerous individual: 3.17 mm.

Color. Translucent orange; distal portion of major chela brighter orange; embryos and ovaries pale green.

Hosts and ecology. In Jamaica, we have found S. regalis   exclusively in Hyattella intestinalis   , typically at depths exceeding 6 m. In Belize, the only other known locality of S. regalis   , they are commonly found in Xestospongia   spp. in addition to H. intestinalis   .

Distribution. Belize ( Duffy 1996 a, d, Macdonald et al. 2006; Ríos and Duffy 2007); Jamaica (this study).

Remarks. Synalpheus regalis   is distinguishable from its close relative, S. elizabethae   , by the possession in non-ovigerous colony members of abdominal pleura (pleura 3–5) that are rounded ventrally versus the ventrally pointed pleura possessed by S. elizabethae   ( Fig. 10 View FIGURE 10 ). Similarly to the S. elizabethae   found here, S. regalis   individuals in Jamaica lack a secondary spine on the major chela protuberance ( Fig. 10 View FIGURE 10 ).
