Synalpheus hoetjesi Hultgren, Macdonald, & Duffy 2010 View in CoL

Material examined. Barbados: 2 ovigerous females, 8 non-ovigerous individuals ( VIMS 08BR6701–5, 8, 12, 6801), Cement Factory, from Hyattella intestinalis . 1 non-ovigerous individual ( VIMS 08BR6401), Harrison’s Point reef, from Hyattella intestinalis . 1 non-ovigerous individual, 1 ovigerous female ( VIMS 08BR9603–4), Thunder Bay, from Agelas clathrodes . Largest ovigerous female, CL 3.84 mm, largest non-ovigerous individual, CL 3.26 mm.

Color. Semitransparent with dull brown major chelae; females with dull olive to orange ovaries and brownish to yellowish-orange embryos.

Hosts and ecology. In Barbados, Synalpheus hoetjesi was collected in the sponges Hyattella intestinalis and Agelas clathrodes ; it also occurs in the sponges Hyattella intestinalis , Xestospongia proxima , and X. subtriangularis in Curaçao (Hultgren et al. 2010).

Distribution. Curaçao (Hultgren et al. 2010); Barbados (this study); Caribbean Panama ( Hultgren & Duffy 2011).

Remarks. The Barbados specimens of Synalpheus hoetjesi were similar in morphology to type specimens from Hyattella intestinalis in Curaçao and grouped with these specimens in phylogenetic trees based on DNA sequences (Hultgren et al. 2010; Hultgren & Duffy 2011). They can be distinguished from the related S. ul Rios and Duffy by the relative width of the distal telson spines (medial spines distinctly thicker than lateral spines in S. hoetjesi , similar in thickness in S. ul) and relatively larger body size (CL = 3.29 MM ± 0.144 SE for S. hoetjesi vs. 2.37 mm CL ± 0.107 for S. ul), and from S. pandionis by the development of the scaphocerite blade (generally absent or vestigial in S. hoetjesi vs.>40% of the length of scaphocerite spine in S. pandionis ).
