Description
The genus ''Kontikia'' includes planarians of elongate body, with a creeping sole that occupies one to two thirds of the body width. The mesenchymal musculature includes well-developed longitudinal muscles forming a ring zone around the intestine.
The
copulatory apparatus may or may not have a distinct penis papilla, depending on the degree of contraction of the reproductive structures.
This led to an initial classification of specimens without a distinct penis papilla in another genus, ''Parakontikia''.
