Gusana (flatworm)
''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 reproductive system of planarians, 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'' *''Gusana hualpensis'' *''Gusana lata'' *''Gusana lujanae'' *''Gusana melipeucensis'' *''Gusana platei'' *''Gusana purensis'' References
