***Xerapoa*** is a [genus](/source/Genus) of [land planarians](/source/Land_planarian) from Brazil.

## Description

The genus *Xerapoa* includes small-sized land planarians with subcylindrical body and anterior end raised. Usually the sensory pits of the anterior region open at the tip of small papillae. The ovaries are located more posteriorly in the body, close to the pharynx, when compared to other genera of the subfamily [Geoplaninae](/source/Geoplaninae), in which the [ovaries](/source/Ovary) are closer to the anterior end. The creeping sole is considerably thin, occupying about one third of the ventral side.[1]

## Etymology

The name *Xerapoa* comes from [Tupi](/source/Tupi_language) *xerapoa* (sharp-pointed), referring to the spiny aspect of the anterior end in species with sensorial papillae.

## Species

The genus *Xerapoa* includes four described species:

- *[Xerapoa hystrix](/source/Xerapoa_hystrix)* Froehlich, 1955
