Gusana is a genus of land planarians found in Chile.
Description
Gusana was defined as land planarians with a broad, leaf-like body that tapers very abruptly anteriorly, giving it a triangular anterior end. The cutaneous musculature, both ventrally and dorsally, is partially sunk into the mesenchyma. The sensory border forms a thick edge around the ventral margin of the anterior end and the sensory pits are internally branched, differently from what occurs in most Neotropical land planarians. The copulatory apparatus has a small intra-antral penis papilla and the female canal enters the genital antrum ventrally.
Species
The genus Gusana currently includes seven species:
- Gusana cruciata (von Graff, 1899)
- Gusana hualpensis Carbayo, 2022
- Gusana lata (von Graff, 1899)
- Gusana lujanae Almeida & Carbayo, 2022
- Gusana melipeucensis Almeida & Carbayo, 2022
- Gusana platei (von Graff, 1899)
- Gusana purensis Bolonhezi, Almeida & Carbayo, 2022
