NOTES ON THE MURAENID GENERA STROPHIDON, LYCODONTIS, SIDEREA, THYRSOIDEA, AND PSEUDECHIDNA, WITH A REDESCRIPTION OF MURAENA-THYRSOIDEA RICHARDSON, 1845

Type species for the muraenid genera Strophidon, Lycodontis, Siderea, Thyrsoidea, and Pseudechidna have been erroneously indicated in past l iterature, as well as in recent keys to genera of the Muraenidae. The history of the generic names is reviewed, and type species found to be the following: Strophidon (type species Strophidon longicaudata McCle lland); Lycodontis (Strophidon literata McClelland); Siderea (Muraena siderea Richardson); Thyrsoidea (Muraena thyrsoidea Richardson); and P seudechidna (Muraena brummeri Bleeker). Brief diagnoses are given for genera as currently applied. The type specimens for Muraena thyrsoidea Richardson and Muraena prosopeion Bleeker are redescribed.
