A new species of the caridean
shrimp genus Periclimenaeus
is described from the Cabo Verde Islands, tropical eastern Atlantic. Periclimenaeus ramili sp. nov. is
morphologically most similar to the north-eastern Atlantic P. aurae dos Santos, Calado &
Araújo, 2008, the western Atlantic P.
pearsei (Schmitt, 1932), and particularly the eastern Pacific P. hancocki
Holthuis, 1951, all sharing many features, especially the reduced
incisor process of the mandible, the general shape of the second pair
of chelipeds and ambulatory pereiopods, and the telson armament. Based
on these features, a new species group is established here to include
these four species. Periclimenaeus
ramili sp. nov. can be readily distinguished from P. aurae and P. pearsei by the shape of the
dactylus of the first pereiopod chela. From P. hancocki,
the new species can be distinguished, among other features, by the
shorter rostrum armed with lower number of dorsal teeth, the relative
length of the scaphocerite to the antennular peduncle, and by the
slender distal articles of the third maxilliped. The new species is
also reported to excavate its own burrows for living inside its sponge
host, a behaviour previously unknown in species of the genus.
