Type: article
Abstract: Freshwater shrimps of the family Atyidae of New Guinea, including those from the Indonesian province of Papua, the Aru Islands, and the country of Papua New Guinea, are reviewed. A taxonomic synopsis is given to the 35 species identified so far, including two new species, namely Caridina iriana and C. yapenensis. Six species are recorded for the first time from New Guinea, namely Caridina mertoni, C. neglecta, C. brevicarpalis, C. endehensis, C. appendiculata, and C. cf. sikipozo. Seven landlocked species are found to be endemic to New Guinea, namely C. demani, C. cognata, C. fecunda, C. rouxi, C. buergersi C. elisabethae, and Parisia holthuisi. Biogeographically, apart from 11 species endemic to New Guinea, the majority of the amphidromous atyid shrimp species are found to be either restricted to the Island Chain of West Pacific (8 species) or restricted to the Indo-Australian Archipelago region, with New Guinea/Solomon Islands being the eastern and India/Sri Lanka being the western limits of their ranges (8 species), and five are restricted to the West Pacific, with Sulawesi/Philippines their western limit. Only three species are widely distributed in the Indo-West Pacific region. Descriptions/diagnoses for the new, taxonomically important or poorly known species, taxonomic discussions, habitat and distribution information for all species are presented.
