Synalpheus androsi Coutiere 1909

Synalpheus androsi Coutière, 1909 (Fig. 4) Material examined: Maranhão—Turiaçu: 1 M, Nordeste Expedition II, St. 111/112, MOUFPE 12510; Pernambuco—Continental Shelf off Recife: 1 M, 1 OV, 10.v.2018, 08°23′04.3′′S 34°40′07′′W, 80.0 m depth, in sponge, DZ / UFRGS 7050; Bahia — Salvador: 1 M, Almirante Saldanha Expedition, St. 1981, 23.ix.1968, 13°48.5′S 38°48.5′W, 49.0 m depth, MOUFPE 9212. Description: Coutière (1909), Ríos & Duffy (2007), Anker & Pachelle (2014). Distribution: Bahamas (Andros Island), Belize (Carrie Bow Cay), Jamaica, Barbados and Brazil (Maranhão, Pernambuco, Bahia and Espírito Santo: Vitória-Trindade chain) (Coutière, 1909; Dardeau 1984; Coelho et al. 2006; Ríos & Duffy, 2007; Macdonald et al. 2009; Hultgren et al. 2011; Anker & Pachelle 2014; this study). Ecology: In association with sponges [e.g., Aiolochroia crassa (Hyatt, 1875), Hyattella intestinalis Lamarck, 1814, Hymeniacidon caerulea Pulitzer-Finali, 1986]; solitarily or in heterosexual pairs; 14– 80 m (Anker & Pachelle 2014; Ríos & Duffy, 2007; this study). Sampled at the continental shelf off Recife (DZ/UFRGS 7050) in association with an unidentified sponge. Remarks: Synalpheus androsi can be identified by the distinct morphology of the third pair of pereiopods, which display a noticeable concavity on the flexor margins of the merus, carpus, and propodus (see Fig. 4B) (Coutière, 1909; Ríos & Duffy, 2007). This study extends the known bathymetric range of the species from 55 m (Anker & Pachelle 2014) to 80 m.
