Bruce, A.J. and Thomas M. Iliffe. 1992. Potamalpheops pininsulae sp.
nov., a new stygiophilic shrimp from New Caledonia (Crustacea: Decapoda: Alpheidae).
Stygologia, 7(4):231-242.
A new species of the alpheid shrimp genus Potamalpheops
Powell, 1979, P. pininsulae, is described and illustrated. This
shrimp is the first stygiophilic alpheid to be reported from the Indo-West
Pacific region, and only the second species of its genus from this area. The
shrimps were collected from a calcareous anchialine grotto on the Isle of
Pines, New Caledonia. The new species is closely related to the only other
Indo-West Pacific species, P. hanleyi Bruce, an inhabitant of
mangroves, rather than the troglobitic Central American species, P.
stygicola Hobbs, found in a freshwater cave in Mexico. P. pininsulae
is easily distinguished from all other species of the genus by its longer
rostrum armed with a ventral tooth. The key to the genus Potamalpheops
provided by Bruce (1991a) is revised to include P. pininsulae.
