Maximum-likelihood tree using cytochrome c oxidase subunit 1 mitochondrial DNA (cox-1 mtDNA) region encompassing Metastrongyloidea helminths. Dirofilaria immitis and Onchocerca lupi were rooted as outgroups. Sequences obtained from the study are highlighted in red. Nucleotide sequences downloaded from the GenBank are indicated with accession number, species name, and country. Bootstrap values are shown at the nodes. The best-fit model was the transition model considering the base frequencies, invariable sites, and discrete Gamma model with four rate categories (TIM + F + I + G4)
