"The Cave Shrimps of the Philippines"

Abstract - The diversity of cavernicolous shrimps of the Philippines is reappraised on the basis of recent as well as old collections. This study shows that the subterranean shrimp fauna of the Philippines is represented only by the family Atyidae, with 11 species in 5 genera--Antecaridina, Jolivetya, Edoneus, Halocaridinides, and Caridina, belonging to three subfamilies--Typhlatyinae, Caridellinae and Atyinae. Nine stygobiont species and 2 stygoxene species are recorded. Of these, five are new to science and four are recorded from the Philippines for the first time. Results of morphological comparisons suggest that the subterranean shrimps of the Philippines might have multiple origins. Three hypothetical origin pathways are proposed. Morphological illustrations are provided. The adaptations of these shrimps to these subterranean habitats and their possible speciation are discussed. -- http://rmbr.nus.edu.sg/bejc/archive/tanngcai.html
