Etymology. The specific name comes from the Latin word comminus (near, hand to hand), referring to the proximity of ITA to RTA, adjective.

Diagnosis. This species can be easily distinguished from other members of this genus by: ITA being very close to RTA, the copulatory ducts ox-horn-shaped anteriorly.
