摘要

To date, the only species of leech reported from the American Alligator, Alligatormississippiensis is Placobdellamultilineata. Seven specimens of a previously undescribed species of Placobdella were collected from the feet and lower jaw of a single female alligator from the Pascagoula River Wildlife Management Area, George County, Mississippi. The new species was named Placobdellasiddalli Richardson & Moser, sp. n., in honor of the contributions of Dr. Mark Siddall to our understanding of the biology of leeches. Placobdellasiddalli Richardson & Moser is similar to other papillated members of the genus Placobdella, but differs from Placobdellaali Hughes & Siddall, 2007, Placobdellarugosa (Verrill, 1874), Placobdellamultilineata Moore, 1953, and Placobdellapapillifera (Verrill, 1872) in coloration, papillation, ventral striping, and in the possession of a relatively large caudal sucker. In addition, molecular comparison of 626 nucleotides of CO-I between the new species and other papillated leeches (P.ali, P.multilineata, Placobdellaornata, P.papillifera, P.rugosa) revealed interspecific differences of 14.0?￠????18.0% (88?￠????113 nucleotides).
