Synalpheus corallinus Macdonald, Hultgren & Duffy 2009

Synalpheus corallinus Macdonald, Hultgren & Duffy, 2009 (Figs. 11, 12) Material examined: Pernambuco — Continental Shelf off Recife: 1 M, 27.ii.2018, 8°13′33.0′′S 34°37′40.3′′W, 50.6 m depth, in sponge, MOUFPE 21814; 1 M, 27.ii.2018, 8°13′52.1′′S 34°37′41.2′′W, 51.8 m depth, in sponge, MOUFPE 21812. Description: Macdonald et al. (2009). Distribution: Jamaica (Discovery Bay) and Brazil (Pernambuco) (Macdonald et al. 2009; this study). Ecology: In sponges, associated with H. intestinalis (Macdonald et al. 2009); in heterosexual pairs; 50.6–51.8 m (Macdonald et al. 2009; Anker et al. 2012; this study). Sampled at the continental shelf off Recife (all lots cited above) in association with sponges, on coral rubble and algae bottom. Remarks: S. corallinus is part of the S. brooksi complex (morphological differences regarding other species of the complex were discussed by Macdonald et al. 2009, Tab. 3, p. 12, Figs. 5–9). Our material agrees well with the description provided by Macdonald et al. (2009) (for comparison, see description and figures in Macdonald et al. 2009 and Figs. 11, 12 herein). The present study provides the first information regarding depth range for the species (50.6–51.8 m), as well as the first record of the species beyond its type locality (Discovery Bay, Jamaica), significantly expanding its known distribution.
