off Cape Verde Is., off E Azores, W Medit. (Gulf of Annaba)
N: 3
(139) F: 1,27-1,05; (700) F: 1,36-0,93; M: 1-0,89; {F: 0,93-1,36; M: 0,89-1,00}

According to Boxshall (1977, p.130) this species is closely related to O. obscura Farran, 1908 but it can be distinguished from it by the structure and armature of P4.
