Phylogenetic relationships of Mesocriconema xenoplax collected from Portugal (MG647831) and other geographical regions, based on the sequence alignment of the D2/D3 rDNA loci. The phylogram was generated using the maximum likelihood method based on the Tamura 3-parameter model with 1,000 bootstrap replications. Bootstrap values are indicated at the nodes. The analysis involved 27 nucleotide sequences. All positions containing gaps and missing data were eliminated. Evolutionary analyses were conducted in MEGA 6.
