Neighbour-Joining (NJ) tree for 16 species-level lineages within the ' revolutum ' group of Echinostoma based on the mitochondrial gene nad 1: Clade A. Based on a 475-nt fragment of nad1. Outgroups: Echinoparyphium aconiatum and Hypoderaeum conoideum. Numbers represent node supports from NJ and Bayesian inference (50% majority rule consensus tree) analyses (only values greater than 70 and 0.95, respectively, are shown). The newly-sequenced European isolates are shown in red; stars indicate adult isolates from natural infections. Sequence identification is as in GenBank, followed by a letter: D, Detwiler et al. [16,17]; G, Georgieva et al. [19]; K, Kostadinova et al. [28]; M, Marcilla et al. (unpublished); M & B, Morgan & Blair [14,26]. The scale-bar indicates the expected number of substitutions per site.
