Mitogenomic phylogenies suggest the resurrection of the subfamily Porrocaecinae and provide insights into the systematics of the superfamily Ascaridoidea (Nematoda: Ascaridomorpha), with the description of a new species of Porrocaecum

^aThe forward strand is marked as “+” and the reverse strand is marked as “−”
^bPositive number in the “Gap or overlap” column indicates the length of the intergenic sequence, with negative numbers indicating the length (absolute number) that adjacent genes overlap (negative sign)
