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.[1]
