Ogyrides alphaerostris ( Kingsley, 1880)

( Figure 13 )

Ogyris alphaerostris Kingsley 1880: 420 , pl. 14, fig. 7.

Material examined. Brazil, Ceará: 1 ov. female, MZUSP 27614, Icapuí, Praia de Tremembé, sand-mud flat, among sea grass beds, in burrow, suction pump, coll. P.P.G. Pachelle & C.B. Mendes, 19.viii.2012 [fcn PP 12-029]; 3 females, MZUSP 32730, Paracuru, Praia da Pedra Rachada, sand-mud flat, in burrows of Callichirus major ( Say, 1818) , suction pump, coll. P.P.G. Pachelle, 11.viii.2014.

Distribution. Western Atlantic: USA (Virginia) to Brazil (Amapá, Pará, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Bahia , Rio de Janeiro, São Paulo, Paraná, Santa Catarina, Rio Grande do Sul); Eastern Pacific (?): Mexico (Baja California and Sinaloa) ( Carvacho & Olson 1984; Hendrickx 1993; Christoffersen 1998; Ferreira & Sankarankutty 2002; Coelho et al. 2006; Almeida et al. 2013a; present study).

Remarks. The specimens from Ceará agree well with the diagnosis of Ogyrides alphaerostris provided by Williams (1984), differing only in the second article of the antennular peduncle being about three times the length of the third (vs. about 2.5 times in Williams’s illustrations). All specimens from Ceará have a small spiniform seta on the distolateral margin of the antepenultimate article of the third maxilliped, as illustrated for the eastern Pacific O. wickstenae Ayón-Parente & Salgado-Barragán, 2013 and also present in the Ceará material of O. hayi Williams, 1981 (see below); whether the specimens from the eastern USA also have such a spiniform seta remains unknown. Our specimens also bear five to eight post-rostral teeth on the carapace, thus falling into the reported variation range of the species ( Williams 1984). Noteworthy, some specimens were extracted from burrows of the large ghost-shrimp, Callichirus major . The identity of the eastern Pacific material of O. alphaerostris needs to be confirmed.
