On a collection of freshwater shrimps (crustacea decapoda caridea) from the philippines, with descriptions of five new species

Abstract

The study deals with a small collection of epigean and hypogean freshwater shrimps made by an Italian speleological expedition in 1991 in various localities of the Philippine Archipelago, and deposited in the Natural History Museum of the University of Florence, Italy. The collection contains 15 species of caridean shrimps in three families. The Atyidae are represented by nine species from three genera: Atyopsis Chace 1983, with one species; Caridina H. Milne Edwards 1837, with seven species, including three new species and two new records for the Philippines; and Parisia Holthuis 1956, with one new species. The Palaemonidae are represented by five species, all of them belonging to the genus Macrobrachium Bate 1868. The Alpheidae are represented only by one new species in the genus Potamalpheops Powell 1979. Detailed descriptions are provided for all new and rarely reported species; taxonomic discussions are provided for all species. © 2004 by the Society of Vertebrate Paleontology.
