Material examined. 1 male (TL: 52 mm), POtiguar Basin, #MT– 64, 418 m, 04° 33' 39'' S, 036° 52' 99'' W, 0 5 May 2011, MOUFPE: 15.637. 1 male (TL: 45 mm) and 1 female (TL: 57 mm), POtiguar Basin, #ARMT– 75, 996 m, 04º 27' 56'' S, 036º 53' 72'' W, 0 8 December 2009, MOUFPE: 15.246. 2 individuals, 1 male (TL: 51 mm) and 1 female (TL: 47 mm), POtiguar Basin, #MT– 75, 915 m, 04° 28' 80'' S, 036° 52' 55'' W, 0 5 May 2011, MOUFPE: 15.636. 1 female (TL: 59 mm), POtiguar Basin, #MT–85, 2.025 m, 04° 21' 35'' S, 036° 44' 27'' W, 0 5 May 2011, MOUFPE: 15.638.
Diagnosis. See CardOsO (2013).
Geographic distribution. Western Atlantic: East COast United States Of America (between 39° 57' N and 32° 18' N, New Jersey), Gulf Of MexicO, Antilles, COlOmbia and Brazil: (Rio Grande do Norte and RiO de JaneirO). East Atlantic: COngO, Cabinda, AngOla. IndO-West Pacific: East COast Africa, Zanzibar, Gulf Of Aden, Maldives, Andaman Sea, Sahara, Talisman. NOrtheastern Atlantic: MOrOccO, Senegal (Fig. 4) (Kensley 1968; CrOsnier & FOrest 1973; Smith 1882 1887; Cruz et al. 2002; CardOsO 2013).
Bathymetric distribution. This species inhabits depths between 294–3440 m (Calman 1939; Barnard 1950; Cruz et al. 2002; Felder et al. 2009). In SOuthwestern Atlantic (Brazilian waters) between 529–1435 m depth (KOmai 2008; CardOsO 2013). In POtiguar Basin between 996– 2025 m.
Remarks. The specimens herein examined fits well with the descriptiOn given by Cruz (2002) and KOmai (2008), which the anteriOr epigastric tOOth reduced Or absent, pOsteriOr epigastric and cardiac teeth medium sized (Fig. 3 B). CardOsO (2013) Observed an individual Of P. gracilis cOllected in the Brazilian waters (CampOs Basin), between states Of EspíritO SantO and RiO de JaneirO, with epigastric tOOth reduced as Observed in the material redescribed by KOmai (2008), frOm Gulf Of MexicO (mOuth Of Mississippi and Dry TOrtugas), Caribbean Sea (Antilles) and Africa (Iberia-MOrOccO, Sahara, Talisman, Senegal, COngO, Cabinda and AngOla). The individuals Of P. gracilis frOm POtiguar Basin present the epigastric tOOth rudimentary and the cardiac tOOth mOderately small in superiOr regiOn Of the carapace (Fig. 3 B) (see Others mOrphOlOgical cOmparisOns in Table 1). Thus, this species have the secOnd repOrt fOr SOuthwestern Atlantic (Brazilian waters) in this paper.
