Figures

Plate 1 issued from : E.L. Markhaseva in Zoosyst. Rossica, 1995, , 1994, 3 (2). [p.229, Figs. 1-2].
Female (from 13°21.6'N, 102°28.9'W): habitus (lateral); 2, Thoracic segment 5 and urosome (lateral, left side).

Nota : Cephalothorax 3.6-3.7 times as long as urosome. Rostrum absent. Points of thoracic segment 5 posterior corners exceeding posterior border of genital segment (dorsal and lateral view), directed slightly backwards (lateral view). P5 present, 2-segmented, rudimentary.
Plate 2 issued from : E.L. Markhaseva in Zoosyst. Rossica, 1995, , 1994, 3 (2). [p.230, Figs.3-7].
Female: 3, habitus (dorsal); 4, thoracic segment 5 and urosome (dorsal); 5, forehead (lateral); 6, right caudal ramus (dorsal); 7, Mx2.

Nota : Genital segment symmetrical. 4th and 5th endites of Mx2 with 1seta spine-like and spinulose ; 1st-4th endites apically with rows of thick sclerotized foliaceous spines (typical of the genus).
Plate 3 issued from : E.L. Markhaseva in Zoosyst. Rossica, 1995, , 1994, 3 (2). [p.231, Figs.8-11].
Female: 8a-b, A1; 9, Md (mandibular palp); 10, Md (gnathobase); 11, Mxp.

Nota : A1 24-segmented, with long setae, shorter than cephalothorax. Md palp base with 3 setae ; endopodite 1 with 2 setae, endopodite 2 with 7 setae. Mxp protopodite without digital sensory appendage distally (as in the type species of the genus, Farran 1905), but with 4 setae, otherwise the setation typical of Aetideidae
Plate 4 issued from : E.L. Markhaseva in Zoosyst. Rossica, 1995, , 1994, 3 (2). [p.232, Figs.12-15].
Female: 12, A2; 13, Mx1; 14, P1; 15, P2.

Nota : A2 exopod shorter than endopod ; exopodite 1-4 with 1 seta each, exopodite 7 with 1 medial and 3 terminal setae. ; endopodite 1 with 2 setae, endopodite 2 with 6 terminal and 1 posterior setae at external and 8 setae at internal lobe. Mx1 gnathobase with 9 terminal spines, 1 thin terminal seta, and 1 seta on the surface of the lobe ; 2nd and 3rd internal lobes as well as protopodite near endopod base with 4 setae each ; endopod and exopod with 11 setae each, external lobe with 7 setae. Each segment of exopod of P1 with external spine, endopod external lobe well developed, with rows of fine spinules apically. Exopodite 3 of P2 with serrated margin between 1st and 2 nd and 3rd external spines.
Plate 5 issued from : E.L. Markhaseva in Zoosyst. Rossica, 1995, , 1994, 3 (2). [p.233, Figs.16-17].
Female: 16, P3; 17, P4.

Nota : Posterior surface of endopodite 2-endopodite 3 of P4 covered with thin hairs.

Remarks

Mesopelagic (825 m), hyperbenthic.
According to Markhaseva (1995, p.233) the species is distinguished from the other species of the genus by the longer points of thoracic segment 5 posterior corners, presence of 1 seta at exopodite 1 of A2 (absent in other species), greater number of setae of Md palp, , serrated margin of P2 exopodite 3 between 1st and 2nd and 3rd external spines, and presence of a rudimentary P5. The species is similar to P. minor in the lack of the digital sensory appendage on Mxp protopodite
