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 1996a , 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 ). Similarly to the S. elizabethae found here, S. regalis individuals in Jamaica lack a secondary spine on the major chela protuberance ( Fig. 10 ).
