Synalpheus yano (Ríos and Duffy)


Synalpheus yano (Ríos and Duffy)  

Color plate 6 A, B

Material examined. Jamaica: non-ovigerous individual, ovigerous female ( VIMS 08JAM4801,02), 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. yano   is most commonly found in Lissodendoryx colombiensis   , but is also found in H. caerulea   and Calyx podatypa   de Laubenfels.

PLATE 7. A, Pseudoceratina (Aiolochroia) crassa   (08JAM 32), including an unidentified soft, filmy grey-brown sponge lining the canals, fore-reef (near M 1 channel marker), Discovery Bay, Jamaica. B, Auletta cf. sycinularia   (08JAM 27), external view, Dairy Bull Reef, Jamaica. C, Same, interior view. D, Agelas cf. clathrodes   (08JAM 61), external view, Columbus Park, Discovery Bay, Jamaica. E, Same, interior view. F, Agelas cf. dispar   (08JAM 82), interior view, Rio Buenos, Jamaica.

Distribution. Belize (Macdonald et al. 2006; Ríos and Duffy 2007); Jamaica (this study).

Remarks. Synalpheus yano   is 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.
