Leptalpheus forceps Williams 1965: 194 View in CoL , figs. 1, 2.

Material examined. Brazil, Ceará: 1 male (?) (heavily damaged specimen), LABOMAR-UFC 444, Fortaleza, Barra do Ceará, Rio Ceará estuary, coll. J. Fausto Filho, 23.i.1968; 1 male, 1 ov. female, OUMNH.ZC.2012-10- 0 0 27, Trairí, Rio Mundaú estuary, sand-mud flat, suction pump, in burrow of Lepidophthalmus siriboia Felder & Rodrigues, 1993 , coll. A. Anker & P.P.G. Pachelle, 26.ix.2011 [fcn 11-113].

Distribution. Western Atlantic: USA (North Carolina to Florida), Gulf of Mexico and Brazil (Ceará, Paraíba, Sergipe) ( Christoffersen 1998; Riul et al. 2008; Felder et al. 2009; present study).

Remarks. Leptalpheus forceps may be more common in Ceará, but is difficult to collect, due to its small size (total length typically less than 10 mm) and extremely cryptic lifestyle, i.e. association with the burrows of the ghost-shrimp Lepidophthalmus siriboia (see below).
