The sponge-dwelling snapping shrimps (Crustacea, Decapoda, Alpheidae, Synalpheus) of Discovery Bay, Jamaica, with descriptions of four new species Author Iii, Kenneth S Macdonald Author Hultgren, Kristin Author Duffy, Emmett text Zootaxa 2009 2199 1 57 journal article 10.5281/zenodo.189568 c668ee01-6eff-451a-9b96-be6f14b35edc 1175-5326 189568 Synalpheus androsi Coutière Figure 2, Color plate 1C Material examined. Jamaica : Non-ovigerous individual, ovigerous female ( VIMS 08JAM3301,02), fore-reef (near M1 channel marker), Discovery Bay, from canals of Hyattella intestinalis . 2 non-ovigerous individuals, ovigerous female ( VIMS 08JAM6501-03), Columbus Park, Discovery Bay, from canals of H. intestinalis . MaxCL ovigerous female: 4.55 mm . MaxCL non-ovigerous individual: 4.62 mm . Belize : Non-ovigerous individual ( VIMS 04CBC0402), Curlew Reef, Belize , from canals of H. intestinalis . Color. Transparent, faintly blue-violet; distal portion of major chela brown-green; embryos brownish or dark green (see Color plate 1C). Hosts and ecology. In Belize (Macdonald et al. 2006; Ríos and Duffy 2007 ), as well as in Jamaica (present study), S. androsi seems to be a pair-forming specialist inhabiting the canals of H. intestinalis . Distribution. Bahamas ( Coutière 1909 ); Belize (Macdonald et al. 2006; Ríos and Duffy 2007 ); Jamaica (this study). Remarks. The unique diagnostic structure of S. androsi , matching concave flexor surfaces of the carpus and merus of the 3rd pereopod, ( Coutière 1909 ) is not as evident in these individuals as in those from other regions (especially in regards to the carpus), but is still distinct enough to recognize this species (see Fig. 2 for a comparison of Jamaican and Belizean individuals).
