Description. For detailed description and illustrations see Duffy (1998); see also Ríos & Duffy (2007).

Size range. Colony members, 2.5–2.8 mm cl; female, 3.1 mm cl.

Colour in life. Semitransparent with pale yellowish tinge; ovaries and fresh eggs pale yellowish-pinkish ( Fig. 21 View FIGURE 21 ); also see colour photograph in Ríos & Duffy (2007).

Type locality. Carrie Bow Cay , Belize .

Distribution. Western Atlantic: Caribbean Sea: Belize [Carrie Bow Cay], British Virgin Islands [ Virgin Gorda], Panama [Bocas del Toro, San Blas Islands] ( Duffy 1998; Ríos & Duffy 2007; present study; see map in Fig. 51 View FIGURE 51 ).

Ecology. Shallow reef-rubble and associated habitats rich in sponges, depth range 2–20 m ( Duffy 1998); obligate symbiont of several demosponges: Agelas clathrodes , Hyattella intestinalis , Hymeniacidon sp. , Lissodendoryx cf. strongylata , and Niphates amorpha ( Duffy 1992, 1998; Ríos & Duffy 2007); living in social groups of several dozen to more than 80 individuals (= colony members), with only one or a few ovigerous females ( Duffy 1998; Ríos & Duffy 2007).

Remarks. The most important distinguishing character of S. chacei is the presence of two rows of gambarelloid setae on the minor cheliped ( Duffy 1998; Ríos & Duffy 2007). This socially living species is presently not known from outside the Caribbean Sea.
