B. Werding, DESCRIPTION OF A NEW PORCELLANID, PETROLISTHES-GERTRUDAE FROM THE SOUTHEASTERN CARIBBEAN-SEA (CRUSTACEA, DECAPODA, PORCELLANIDAE), Proceedings of the Biological Society of Washington, 109(2), 1996, pp. 306-310
A new species of the genus Petrolisthes Stimpson, 1858, P. gertrudae,
from the West Indies is described. The new species belongs to a group
of Petrolisthes species characterized by the complete lack of spines o
n the carapace and pereopods 1-5. The new species can be easily distin
guished from other species of that group by the convex shape of the ca
rpal lobe of the chelipeds, and by the pubescence which covers the out
er margins of the chelae.
