In EASIN is considered cryptogenic. As far as I know it is known from California (Pacific Ocean). If records for the W Atlantic are lacking, I would suggest to include it among aliens.

Pherusa brevituba Soule 1951 was indeed described from California, where it is now well-known. In 2005 it was reported from the Mediterranean (Ustica, Sicily) by Chimenz & d'Hondt (2005). These authors apparently regard it as an alien species. This assumption is warranted as it is apparently not known from other European locations. Furthermore, a phylogenetic argument is that no other European Pherusella species are known. P. flabellaris is a Pacific species as well (China Sea) and P. tubulosa is reported to be cosmopolitan (Chimenz Gusso et al., 2004), possibly as a result of introductions to other regions.
