Alaria、Didelphodiplostomum和Pharyngostomoides是已知寄生于哺乳动物终末宿主的双殖吸虫属。尽管最近有许多分子系统发育研究的diplostomids，有限的DNA序列数据可从diplostomids寄生在哺乳动物。在此，我们提供了第一个28 S rDNA和cox 1 mtDNA序列的形态鉴定，成人标本Didelphodiplostomum和Pharyngostomoides。新产生的28 S序列被用来推断这两个属的系统发育之间的相互关系，在其他主要谱系的diplostomoideans。根据28 S序列和形态学资料的分析，我们认为咽口类（Pharyngostomoides）是Alaria的次异名，而Didelphodiplostomum是Tylodelphys的次异名。模式种为Alaria procyonis，模式种为Pharyngostomoides adenocephala和Pharyngostomoides dasyuri。十一月，腺头状海蛞蝓nov.和Alaria dasyuricomb. nov.;将模式种Didelphodiplostomum variabile和Didelphodiplostomum nunezae转入Tylodelphysasvariabiliscomb。nov.和Tylodelphys nunezaecomb.此外，Alaria ovaliscomb. Nov.（以前包括在Pharyngostomoides）恢复和转移到Alariaspp的形态学研究的基础上，良好的固定，成人标本和比较的cox 1DNA序列。根据形态学的回顾，恢复了双口门属。
Alaria,DidelphodiplostomumandPharyngostomoidesare among genera of diplostomid digeneans known to parasitize mammalian definitive hosts. Despite numerous recent molecular phylogenetic studies of diplostomids, limited DNA sequence data is available from diplostomids parasitic in mammals. Herein, we provide the first 28S rDNA andcox1mtDNA sequences from morphologically identified, adult specimens ofDidelphodiplostomumandPharyngostomoides. Newly generated 28S sequences were used to infer the phylogenetic interrelationships of these two genera among other major lineages of diplostomoideans. The phylogeny based on 28S and a review of morphology clearly suggests thatPharyngostomoidesshould be considered a junior synonym ofAlaria, whileDidelphodiplostomumshould be considered a junior synonym ofTylodelphys.Pharyngostomoides procyonis(type species),Pharyngostomoides adenocephalaandPharyngostomoides dasyuriwere transferred intoAlariaasAlaria procyoniscomb. nov.,Alaria adenocephalacomb. nov.andAlaria dasyuricomb. nov.;Didelphodiplostomum variabile(type species) andDidelphodiplostomum nunezaewere transferred intoTylodelphysasTylodelphys variabiliscomb. nov.andTylodelphys nunezaecomb. nov.In addition,Alaria ovaliscomb. nov.(formerly included inPharyngostomoides) was restored and transferred intoAlariabased on a morphological study of well-fixed, adult specimens and the comparison ofcox1DNA sequences amongAlariaspp. The diplostomid genusParallelorchiswas restored based on review of morphology.
