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.

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).

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

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.

Distribution map of Paracomantenna wishnerae by geographical zones

| | | Loc: | | | E Pacif. (off E Clipperton Is.) | | | N: | 1 | | | Lg.: | | | (259) F: 2,6-2,55; {F: 2,55-2,60} | | | Rem.: | 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 | | | Last update : 14/02/2020 | |
