Distribution. Bahamas (Garth 1978), Gulf of Mexico (Felder et al. 2009), Colombia (Cruz Castaño & Campos 2003; Monroy López & Solano 2005), Curaçao, Venezuela (Vera-Caripe et al. 2017) and Brazil (Paraíba, Pernambuco, Alagoas, Bahia, São Paulo) (Gouvêa 1986; Melo 1998; Nogueira et al. 2015). Brazilian oceanic islands: Fernando de Noronha Archipelago, Rocas Atoll (Fausto-Filho 1974; Alves et al. 2008; Bouth et al. 2011) and Trindade and Martin Vaz Archipelago (present study).
Ecological notes. Relatively little is known about the biology and ecology of Teleophrys pococki. This species has been reported associating with many different substrata, including coral reef and dead coral (Rathbun 1924a; Vera-Caripe et al. 2017), Mussismilia corals (Bahia, Nogueira et al. 2015; Trindade Island, see under material examined), under stones (Garth, 1978), and more commonly associating with macroalgae such as Centroceras sp., Ceramium sp., and Chaetomorpha sp. (Gouvêa, 1986; Monroy López & Solano, 2005). In Trindade, T. pococki decorates itself by attaching green and red algae to the carapace and legs whose lamelliform lobes on P2–P5 facilitate fouling accumulation (Fig. 24B, F, G). The association with the sea urchin Tripneustes ventricosus (Lamarck) (Monroy López & Solano 2005; Vera-Caripe et al. 2017) and Echinometra lucunter (Linnaeus) (Hayes et al. 2016) is probably occasional. Teleophrys pococki and Mithrax forceps are the commonest spider crab species in Trindade and Martin Vaz, where males, ovigerous females and juveniles have been found together in macro- and calcareous algae in tide pools and occasionally hard corals down to 22 m. It has been reported as prey for Octopus insularis juveniles in the Rocas Atoll (Bouth et al. 2011).
Remarks. Two species of Teleophrys have been recorded from the Brazilian coast, T. pococki and T. ornatus (type locality: Mayaguez Harbor, Puerto Rico). The specimens from Trindade and Martin Vaz are confidently referred to T. pococki on the account of the carapace approximately as broad or broader than long, and P2–P5 cristate dorsally only (Fig. 24A, C–E) (vs carapace distinctly longer than broad and P2–P5 cristate dorsally and ventrally in T. ornatus) (Fig. 25B).
Developing specimens tend to have more granular carapace and spiniform anterolateral teeth (Fig. 24E, 25A), which become smaller and develop into rounded, low tubercles in grown specimens (Fig. 24A, C). Mature females have translucid pleonal somites 4–6 (Fig. 24C).
Upon examination, the ovigerous female MZUSP 16706 from the northeastern coast of São Paulo previously identified as T. ornatus (Alves et al. 2006; Alves et al. 2012b) proved to belong to T. pococki.
Materials of T. ornatus previously recorded from Brazil (not available to us) were obtained from the Fernando de Noronha Archipelago (1 juvenile male dredged between 13–36 m reported by Miers, 1886: 89, pl. 10, figs 3a, b, as Mithrax sp. See Rathbun 1925; 1933) (Fig. 25B, C), and from Salvador (Bahia) (Gouvêa, 1986). However, Gouvêa’s (1986) illustrations of the lamelliform lobes on P2 suggest that all his specimens actually belong to T. pococki. Pocock’s (1890: 508) Mithrax (Teleophrys) cristulipes from Fernando de Noronha actually refers to T. pococki (see Rathbun 1925).
The date of publication of Teleophrys pococki is 1924, not 1892 as in Ng et al. (2008).
