Supramontana is a genus of land planarians from South America.
The genus Supramontana is characterized by the presence of a cephalic retractor muscle not associated with cephalic glands. This muscle is similar to the one found in the genera Issoca and Luteostriata , but in Supramontana the organ lacks cephalic glands, which are present in the other two genera. [1]
The copulatory apparatus of Supramontana has a permanent penis papilla and a long common ovovitelloduct. [2]
The name Supramontana comes from the Latin words supra (on the top) and montanus (of the mountains). It is a reference to the type-locality of Supramontana irritata , the city of São Francisco de Paula, in Southern Brazil, whose previous name was São Francisco de Paula de Cima da Serra (on the top of the mountains). [2]
There are two described species in the genus Supramontana: [3]
A molecular study on the phylogeny of the subfamily Geoplaninae nested the genus Supramontana inside the genus Luteostriata. The two genera formed a monophyletic clade with the genus Issoca . [4] The clade is supported by at least one synapomorphy, the presence of a cephalic retractor muscle derived from the longitudinal cutaneous ventral musculature that anteriorly dissipates by detaching its fibers, making them open in a fan-like fashion towards the body margins.
