Genus CALLIPALLENE Flynn, 1929 
(pro Pallene Johnston, 1837) 
Chelifore 2-jointed, chelate, opposed in front of proboscis. Oviger 
10-jointed, with spines on terminal joints. Propodus without large 
basal spines, auxiliary claws usually present. Trunk elongate, last 
two segments often coalesced, cephalic segment prolonged into a neck. 
Four species of this characteristic genus have been identified from 
western Atlantic waters. One of them is a deep-water species, while 
the other three have all been taken in surface tows at one time or 
another. Key to the species represented:

This is the smallest species of pycnogonid from the Woods Hole 
region. Although it is somewhat larger in extent than Tanystylum 
orbiculare, its body is smaller and the legs are so delicate that the 
animal looks smaller than it actually is. 
Callipallene brevirostris is one of the permanent members of the 
fauna of the Woods Hole region, although it was apparently not so
