Pimea monticola is characterized by an expanded anterior end with a musculo-glandular organ in the form of an adhesive pad. The cutaneous longitudinal musculature is partially insunk into the mesenchyma and originates a retractor muscle associated to the musculo-glandular organ. The mesenchymal musculature is weak. The copulatory apparatus lacks adenodactyls and has an intra-antral penispapilla.
