Abstract |
The isopod genus Echinozone is defined by a row of spines
on the anterior margins of the pereonites, mainly pereonites
1 4 . Some species of this genus for instance Echinozone
quadrispinosa (Beddard, 1886), E. spinosa Hodgson, 1902
and E. spicata (Hodgson, 1910), appear quite similar at first
glance, especially in the pattern of the spines on the dorsum
of the body. The variability of this character has led to E.
spinosa being regarded as E. spicata, and E. quadrispinosa
being synonymized with E. spinosa (Amar &Roman, 1973).
A study of the type material has shown this latter attribution
to be incorrect. The Occurrence of this genus in Antarctica
is summarized for the first time and a key to the Antarctic
species is presented. |
