 Issued from : E.L. Markhaseva in USSR Acad. Sci., Zool. Inst., Explor. Fauna Seas. Marine Plankton, 1989, 41 (49). [p.52, Fig.10]. Female: Thoracic segment 5 and genital segment. Nota from the key: 1 - Genital segment symmetrical. 2 - Thoracic posterior corners segment 5 ± asymmetrical. 3 - Corners of thoracic segment 5 not in expansion, rounded, with 1 sine on the right side. 4 - Genital segment length nearly as long as wide. Nota Female: Complement from Markhaseva (1996, p.293): Cephalothorax about 4.5 times longer than urosome. 5th thoracic segment asymmetrical; with spine on the right. Genital segment symmetrical, barrel-like. Urosomal segments covered with hairs. A1 reaching the distal border of anal segment. Exopod of P1 3-segmented, with indistinct separation between exopodal segments 1 and 2. Endopod of P2 2-segmented. Coxopodite of left P4 with 12 spines, right with 9 spines.

Geographical distribution of P. vervoorti.
1: from Tanaka, Omori, 1969; 2: present occurrence. |
| | | | Loc: | | | Japan (Izu), Mariana Trench.
Type locality: Japan (Izu region). | | | | N: | 3 | | | | Lg.: | | | (111) F: 5,71; 5,66; {F: 5,66-5,71} | | | | Rem.: | bathy & abyssopelagic.
Markhaseva (1996, p.294) remarks that Tanaka & Omori (1969) noted close connection between this species and P. vervoorti Vervoort, 1949, but distinguished the species in segmentation of P2 endopod (1-segmented in P. semispina vs 2-segmented in P. vervoorti), in highter number of spines on coxopodite of P4 (7-8 in P. semispina vs 9-12 in P. vervoorti), in different proportion of endopod and exopod of A2 (exopod 1.2 times endopod in P. semispina), and in different arrangement of hairs on genital segment. | | | Last update : 30/01/2015 | |
