Resolving species boundaries in Mediterranean Xiphinema (Nematoda: Longidoridae) through multivariate morphometrics and multilocus profiling: four new species and two cryptic complexes
By integrating multivariate morphometrics and multilocus molecular profiling of 50 *Xiphinema* populations from the Mediterranean Basin, this study resolves species boundaries through the description of four new species, the identification of two cryptic complexes, and the expansion of available genetic resources.
