Species Pseudochirella accepta - Plate 1 of morphological figuresissued from : E.L. Markhaseva in Proc. Zool. Inst. RAN, St. Petersburg, 1996, 268. [p.256, Fig.202].
Female (from NW Pacif.: Kuril Trench). Ce: forehead (lateral); CP4: coxopod of P4 (portion).

Species Pseudochirella accepta - Plate 2 of morphological figuresissued from : J.A. Zvereva in Crustaceana, 1976, 31 (2). [p.201, Figs.1-12].
Female (from S Bering Sea): 1, habitus (dorsal); 2, idem (right lateral side); 3, rostrum (frontal view); 4, A2; 5, Mx2; 6, Mxp; 7, P1; 8, P2; 9, P3; 9a, detail of terminal spine of P3; 10, P4; 11, inner edge of coxopod of P4; 12, genital somite (ventral).

Nota: Head without crest; 4th and 5th thoracic segments separate. Rostrum short, stout, non-bifid. A1 longer than the cephalothorax, reaches the distal margin of th 2nd urosomal segment. The inner ramus of A2 is about half the length of the external ramus. Urosome 4-segmented, covered with dense seta; every segment bears spinules on its distal margin. Genital segment asymmetrical (when observed from the right and above a swelling is visible; when seen from the left side a lobe with a forwardly directed spine is to be seen; the ventral prominence is rounded).

Species Pseudochirella accepta - Plate 3 of morphological figuresIssued from : E.L. Markhaseva in USSR Acad. Sci., Zool. Inst., Explor. Fauna Seas. Marine Plankton, 1989, 41 (49). [p.53, Fig.20].
Female: Thoracic segment 5 and genital segment.
Nota from the key:
1 - Genital segment asymmetrical.
2 - Both left and right thoracic posterior corners without spines.
3 - Thoracic posterior corners triangular shape (lateral view).
4 - Genital segment with protuberance present in its anterior part..

Geographical distribution of P. accepta .
1: present occurrences (black circle).
Kuril-Kamchatka Trench, S Bering Sea, Aleutian Trench.

Type locality: 55°05'N, 171°06'E.
N: 3
(37) F: 7,6-7,2; (261) F: 7,6; {F: 7,20-7,60}

For Zvereva (1976, p.201) the species is closely related to P. pustulifera Sars (1905) and P. tuberculata Tanaka (1957).
