Type locality: 27.4337° N, 34.1510° E. | | | | N: | 1 | | | | Lg.: | | | (1234) F: 1,05- 1,09; M:: 1,00-1,03; {F: 1,05-1,09; M: 1,00-1,03} | | | | Rem.: | Collected from the sandy bottom of a fissure (3-5 m deep) connected with the sea. For Zagami & al. (2019, p.281) this species appears closely related to P. ammophila and P. platysoma, with which it shares the following combination of characters:
- 4th and 5th pedigerous somites completely fused wit dorsolateral processes and rounded postero-lateral lobes;
- Male left P5 with short endopod.- Both 3rd exopodal segments of the male P5 carry a long a stout terminal process completely incorporated into segment.
This combination of characters is unique among Paramisophria species. | | | Dernière mise à jour : 19/06/2023 | |
