Kontikia ventrolineata

Originally described as Geoplana ventrolineata by Dendy, this species was later transferred to the genus Parakontikia as its type-species. Parakontikia was differentiated from the closely related genus Kontikia by the lack of a penis papilla, which is present in Kontikia.^[7] However, a later analysis of specimens found in South Africa and England revealed that they matched the description of both Parakontikia ventrolineata and Kontikia mexicana and that both species differed solely by the presence of a penis papilla in the latter, with both color pattern and the internal structure being identical. As a result, both species were synonymized under the new combination Kontikia ventrolineata.^[3] However, despite this synonymization, the name Parakontikia ventrolineata is still widely used to refer to this species.^[8]

The complete mitogenome of Kontikia ventrolineata is 17,210 bp in length.^[8] and shows a cytochrome c oxidase subunit 2 gene unusually long, a characteristic shared with other members of the subfamily Rhynchodeminae.^[8][9]
