Figure 2 in Molecular phylogeny supports invalidation of Didelphodiplostomum and Pharyngostomoides (Digenea: Diplostomidae) and reveals a Tylodelphys from mammals

Figure 2. Phylogenetic interrelationships among eight species of Alaria (syn. Pharyngostomoides) based on BI analysis of partial 28S rDNA gene sequences. BI posterior probability values lower than 80% are not shown. The new sequences generated in this study are indicated in bold. The scale bar indicates the number of substitutions per site. Biogeographical realm and family of definitive host from which specimens were collected are provided when possible; the information on biogeographical realms and families of definitive hosts is provided only for taxa confirmed with sequence data. Abbreviations of biogeographical realms: N, Nearctic; P, Palaearctic. Abbreviations of family of definitive host: Can, Canidae; Fel, Felidae; Mep, Mephitidae; Mus, Mustelidae; Pro, Procyonidae. ‡ All collected specimens are immature.
