Synalpheus williamsi Ríos and Duffy  

Material examined. Jamaica: non-ovigerous individual ( VIMS 08JAM 6601), Dairy Bull Reef, from canals of Hymeniacidon caerulea   . Non-ovigerous individual, ovigerous female ( VIMS 08JAM6701,02), Dairy Bull Reef, from canals of Hymeniacidon caerulea   . MaxCL non-ovigerous individual: 2.95 mm. Color. Golden-brown; distal portion of major chela bright orange-red; ovaries and embryos green. Hosts and ecology. Synalpheus williamsi   was only found in the midnight-blue sponge Hymeniacidon caerulea   in Jamaica.

Distribution. Belize (Macdonald et al. 2006; Ríos and Duffy 2007); Jamaica (this study). Remarks. As has been mentioned in accounts of S. williamsi   from other regions (Ríos and Duffy 1999), individuals often have traces of dark blue in their gut, presumably from the pigment of their host sponge H. caerulea   .

PLATE 6. A, Synalpheus yano   ovigerous female (08JAM 4601) from Hymeniacidon caerulea, Columbus Park, Discovery Bay   , Jamaica. B, Synalpheus yano   non-ovigerous individual (08JAM 4602) from Hymeniacidon caerulea, Columbus Park, Discovery Bay   , Jamaica.
