The dimensions seem to be correlated with the salinity.
Report of this form off SW Ireland by I.C. Thompson (1903 a, p. 31) needs to be confirmed, as well as the form reported by Dakin & Colefax (1933, p.207) in Australia (New South-Wales).
Possible introduction in the Mediterranean from the Red Sea.
After Wellershaus (1969, p.273) the animals tend to reduce or loose spines on the abdominal segment 1 of the female: the spines cannot always be taken as a good character for identification since they are subject to reduction. In some females the segment 9 of A1 bears 1 or 2 small spinules near the distal margin on the posterior side. | | | Last update : 17/04/2020 | |
| | | | The species is not mentioned by Delalo (1966); I checked the list of species in table 4 p.69 of the russian text.
