pamphorum Marcus 
Mello-Leitéo (1945) has proposed another Brazilian species, 
Pycnogonum leticiae, which is very close to if not indentical with 
pamphorum. The only noteworthy difference seems to be the presence 
of a small tubercle just behind the ocular tubercle in leticiae.

Pycnogonum littorale is one of the characteristic denizens of the 
North Atlantic littoral. On the coast of the United States it is found 
from Eastport, Maine, to Long Island Sound. The local bathymetric 
range is from shore line to 810 fathoms. Although Stephensen listed 
Barbados for this species, it is not represented in the museum collec-
