Redescription of five species of Athelginae Codreanu & Codreanu, 1956 (Isopoda, Bopyridae), with new localities and new hosts

Abstract All members of the Athelginae are abdominal parasites of paguroid crabs. Five species of athelgines from the Florida Museum of Natural History are reported here, three from new localities and hosts. Allathelges pakistanensis Kazmi & Markham, 1999 is recorded from Oman, from the type host. Athelges caudalis Barnard, 1955 is recorded from the Philippines from a new host, Calcinus latens (Randall, 1840). Parathelges sp., closely resembling the Atlantic species P. tumidipes Markham, 1972, is recorded from the Federated States of Micronesia from Clibanarius corallinus (H. Milne Edwards, 1848). New specimens of Pseudostegias dulcilacuum Markham, 1982 and Parathelges aniculi (Whitelegge, 1897) are recorded from Thailand and the Philippines from known hosts. Keys to species of Pseudostegias, Parathelges and Athelges are provided, and recorded hosts and localities of all species of Athelges and Parathelges are summarized.
