摘要
Maritrema corai n. sp. is described based on material from the intestine of the white ibis Eudocimus albus (L.) (Threskiornithidae) in Mexico. The new species can be distinguished morphologically from all congeners by the unique combination of the following morphological features: a very long cirrus sac attenuated distally [cirrus sac to body length ratio 1:0.90-1.29 (mean 1:1.07)]; a large, elongate-oval seminal receptacle, located dorsally between the cirrus sac and ovary; and long, filiform, unarmed, evaginable cirrus. Phylogenetic analyses of 28S ribosomal DNA (rDNA) sequences for the new species and for Maritrema spp. and Microphallus spp. depicted strong support for the two genera (excluding Microphallus fusiformis) and revealed close relationships between Ma. corai n. sp. and the clade formed by Maritrema novaezealandense Martorelli, Fredensborg, Mouritsen & Poulin, 2004, Maritrema heardi (Kinsella & Deblock, 1994) and Maritrema cf. eroliae.
