Material examined. Jamaica: non-ovigerous individual, ovigerous female ( VIMS08JAM4801,02), Columbus Park, Discovery Bay, from canals of Hymeniacidon caerulea. MaxCL ovigerous female: 3.32 mm. MaxCL non-ovigerous individual: 3.75 mm. Color.Dull gold; darker in the distal portion of the major chela; embryos and ovaries brick red.
Hosts and ecology.This pair was found in the midnight-blue sponge Hymeniacidon caerulea. In Belize, S. yanois most commonly found in Lissodendoryx colombiensis, but is also found in H. caeruleaand Calyx podatypade Laubenfels. PLATE 7.A, Pseudoceratina( Aiolochroia) crassa(08JAM32), including an unidentified soft, filmy grey-brown sponge lining the canals, fore-reef (near M1 channel marker), Discovery Bay, Jamaica. B, Aulettacf. sycinularia(08JAM27), external view, Dairy Bull Reef, Jamaica. C, Same, interior view. D, Agelascf. clathrodes(08JAM61), external view, Columbus Park, Discovery Bay, Jamaica. E, Same, interior view. F, Agelascf. dispar(08JAM82), interior view, Rio Buenos, Jamaica.
Distribution. Belize(Macdonald et al. 2006; Ríos and Duffy 2007); Jamaica(this study).
Remarks. Synalpheus yanois another member of the morphologically similar complex of species that includes S. pandionis, S. dardeaui, and S. ul. It can be distinguished by its complete lack of a blade on the scaphocerite, and by the equally sized spines of the distal margin of the telson.
