Typton carneus Holthuis, 1951 View in CoL

( Figure 16 View FIGURE 16 )

Typton carneus Holthuis 1951: 162 View in CoL [in part], pl. 51, figs. a, e, k, l.

Material examined. Brazil, Ceará: 1 female, MZUSP 28192, Cascavel, Praia da Caponga, rocky intertidal, in sponge Tedania ignis (Duchassaing & Michelotti) , coll. P. Pachelle & C. Licarião, 04.vi.2011 [fcn PP 11-005]; 2 females, LIMCE-UFC 689, same collection data [fcn PP 11-004].

Comparative material. Typton distinctus Chace, 1972 . Brazil, Rio de Janeiro: 1 female, MZUSP 31506, Arraial do Cabo, Praia do Forno, “Transect 1”, no further data.

Distribution. Western Atlantic: USA (western Florida), Bahamas, Cuba (Los Arroyos), Mexico ( Bahía de la Ascensión), Haiti ( Tortuga), Barbuda, Tobago and Brazil (Fernando de Noronha, Ceará, Paraíba, Pernambuco) ( Vieira et al. 2012; present study).

Remarks. Typton carneus appears to be most closely related to another western Atlantic species, T. distinctus Chace, 1972 ( Figure 17 View FIGURE 17 ). The latter species is known from two other Brazilian states, Pernambuco and Rio de Janeiro ( Pachelle et al. 2015), but has not yet been found in Ceará. The distinguishing characters between the two species involve the shape of the rostrum and second pereiopod carpus, as well as the orientation of the major cheliped dactylus ( Chace 1972; Pachelle et al. 2015). These differences, discussed in Pachelle et al. (2015), are illustrated in Fig. 16 View FIGURE 16 ( T. carneus ) and Fig. 17 View FIGURE 17 ( T. distinctus ) to enable an easier identification of the Brazilian material.
