***Timyma*** is a [genus](/source/Genus) of [land planarians](/source/Land_planarian) from Chile. It is the sole genus of the subfamily **Timyminae**.

## Description

The genus *Timyma* includes planarians of elongate body and spatula-like anterior end. Although most land planarians native from South America have dorsal testes, *Timyma* has ventral testes, which at first suggested that it is related to the [Australasia](/source/Australasia) species of the tribe [Caenoplanini](/source/Caenoplanini).[1] However, the longitudinal cutaneous musculature of *Timyma* is very weak, differently from other genera in this tribe.[2] However, molecular studies confirmed that it is more closely related to other land planarians in South America, having a sister-group relationship with the subfamily [Geoplaninae](/source/Geoplaninae).[3] The [copulatory apparatus](/source/Reproductive_system_of_planarians) lacks adenodactyls and a permanent penis papilla.

## Species
