Kenkiidae is a family of freshwater triclads. Their species can be found sporadically in caves, groundwater, and deep lakes in Central Asia, Far East and North America.
Kenkiidae species have the testicles situated anterior to the pharynx, feature also common in the Dugesiidae and Planariidae. They have an anterior adhesive organ. The inner muscles of the pharynx are divided in two layers. Kenkiidae species are not pigmented and they used to be blind.
Kenkiidae is the sister group of the family Dendrocoelidae. Both families have an apomorphic anterior adhesive organ.
