( GCRL 3049 View Materials ), MAFLA station 2424, 29°13´N 85°00´W, 27 m, medium sand, coll. coarse sand, coll. 1975, det. Heard & Sieg, 1983 GoogleMaps ; 3 spec. ( GCRL 3051 View Materials ), MAFLA station 2529, 29°55´N 86°06´W, 38 m, coarse sand, coll. 1975, det. Heard & Sieg, 1983 GoogleMaps ; 15 spec. ( GCRL 3045 View Materials ), MAFLA station 2530, 29°51´N 86°06´W, 41 m, medium sand, coll. 1976, det. Heard & Sieg, 1983 GoogleMaps ; 2 spec. ( GCRL 3043 View Materials ), MAFLA station 2748, 27°37´N 83°53´W, 50 m, coarse sand, coll. 1976, det. Heard & Sieg, 1983 GoogleMaps ; ~ 35 specimens (adult males, females, juveniles, mancas, Fig. 1A), Culebra Island, Puerto Rico, 28 m, coll. 2003; 1 ovigerous female and 2 adults ( MZUSP 19692 View Materials ) .

Diagnosis (adult). Rostrum rounded. Pleotelson broader than long. Antennule inner flagellum with two articles. Pereopod 1 dactylus with three ventral teeth associated with short spinule. Dactylus of pereopods 1–6 with distal recurved curled sensory setae.

Type locality. Ponta dos Calderos e a Ilha Redonda , Brazil ( Fig. 97 View FIGURE 97 ) .

Geographic Distribution. Brazil, Caribbean Sea ( Puerto Rico), NW Atlantic (South Florida), eastern Gulf of Mexico ( Fig. 97 View FIGURE 97 ).

Remarks. Examination of new material and MAFLA material extends this species range into the Caribbean Sea ( Puerto Rico) and the eastern Gulf of Mexico. This species can easily be distinguished from its only other congener P. mirabilis and is unique among tanaidaceans in having curled sensory setae on the dactylus of the pereopods (Fig. 99C). Examination of mancas (postembryological instars with incompletely developed postcephalic appendages) revealed the presence of exopodites on the last two pereopods. This is the first published account of this occurring in a species of Psammokalliapseudes and might be a synapomorphy of the family. We confirm the presence of this character in a species of Hemikalliapseudes (unpublished data), the first report of this occurring in the Hemikalliapseudinae . The only other group of tanaidaceans reported to have this character is the subfamily Pseudosphyrapodinae in the family Sphyrapodidae (Guţu and Heard, 2002).
