Antenna II ventral margins of the 5th peduncular article and first 4-9 flagellar articles (other one or two articles with sparse plumose setae) densely covered with plumose setae (brush setae). Palp of maxilla I with median constriction. Coxal plate I sub-quadrate with distinctive cups; Gnathopod I, basis lacking distinct anterodistal lobe (hydrodynamic lobe). Gnathopod II, carpus lobe present in juvenile male and absent on adult male. Coxal plate V posterior lobe smaller than anterior lobe; Peraeopod V, basis rounded. Peraeopod VII slender, basis rounded. Uropod I, peduncle with one distomedial robust seta; rami subequal with 3-4 robust setae on outer ramous and 1-2 robust setae on inner ramus. Uropod II, rami sub-equal in length. Uropod III, outer ramus with 5-9 apical robust setae. Telson acute. Female. Description based on a 10.6 mm length specimen. Gnathopod I, basis with anterodistal lobe.</p><p>Distribution.</p><p>Northern, western, and eastern Atlantic coasts; north eastern Pacific coast.</p><p>Remarks .</p><p>The genus Ptilohyale includes 12 species: P. barbicornis (Hiwatari &amp; Kajihara, 1981); P. barnardi (Chevreux, 1925); P. bisaeta (Kim &amp; Kim, 1991); P. brevicrus Eun et al., 2014; P. crassicornis (Haswell, 1879); P. eburnea (Krapp-Schickel, 1974); P. explorator (Arresti, 1989); P. iole (Barnard, 1970); P. littoralis (Stimpson, 1853); P. plumulosus (Stimpson, 1857); P. ptilocerus (Derzhavin, 1937); P. tristanensis (Macnae, 1953) (Bousfield and Hendrycks 2002, Eun et al. 2014, Lowry 2010). Of these, the descriptions of three of the species showed characters not ascribable to Ptilohyale sensu Bousfield &amp; Hendrycks (2002). Ptilohyale barnardi (formerly Hyale barnardi) has brush-setae in antenna II that start at the 4th peduncular article (see Chevreux 1925, Fig. 4A); P. tristanensis (formerly Allorchestes tristanensis) (see Macnae 1953, Fig. 4B) and P. eburnea (see Krapp-Schickel 1974, Fig. 4C), do not have brush-setae in antenna II. The absence of some diagnostic character states makes us consider Ptilohyale barnardi, P. tristanensis, and P. eburnea as nomina dubia, and we encourage further investigations.</p></div>	https://treatment.plazi.org/id/6A235189B0DC5FE02B472636CF05344F	Public Domain	No known copyright restrictions apply.
