Additionally, new morphological and morphometric data are provided for two previously described species from Europe, P. brevicauda (Kotlan, 1928) Paramonov, 1952 and P. clavus (von Linstow, 1901) Sudhaus and Furst von Lieven, 2003. A phylogeny including these four species was inferred from a dataset including 26 ribosomal protein-coding genes, sequences of which are original for P. bulgaricus n. sp. and P. clavus. Relationships support a radiation of all sequenced European Pristionchus species from a single, gonochoristic common ancestor, and current knowledge of species ranges supports "western" and "eastern" clades. Similar diagnostic morphologies reflect the close relationships among the new and recharacterized species, especially P. bulgaricus n. sp., P. brevicauda, and P. clavus, although mating tests as well as genetic and phylogenetic separation support their identities as unique species. Our results show that Pristionchus species in Europe are more diverse than typological characters suggest, and thus biological and molecular profiling will be essential for future delimitation of Pristionchus species from the region. | | Free Keywords: | biogeography; gonochorism; hermaphroditism; morphology; morphometrics; phylogeny; ribosomal protein genes; taxonomy | | External Publication Status: | published | | Document Type: | Article |
