Description

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]

Etymology

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]

Species

There are two described species in the genus Supramontana:[3]

Phylogeny

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.[1][4]

gollark: And you can verify that.
gollark: Unless it can somehow precommit to torturing the simulations.
gollark: If it values suffering for its own sake it might as well do it anyway, but I don't think doing the torturing would advance other goals.
gollark: If you ~~*do* pull it~~ leave it contained, I don't think it has any actual reason to torture the simulation, since you can't verify if it's doing so or not and it would only be worth doing at all if it plans to try and coerce you/other people later.
gollark: You can hash it on each end or something to check.
