Description

The tribe Pelmatoplaninini is defined as containing land planarians with a narrow body with tapered anterior end. The

eye An eye is a sensory organ that allows an organism to perceive visual information. It detects light and converts it into electro-chemical impulses in neurons (neurones). It is part of an organism's visual system. In higher organisms, the ey ...

s are numerous and clustered along the sides of the body on the anterior half, usually not extending behind the mouth. The

pharynx The pharynx (: pharynges) is the part of the throat behind the human mouth, mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates ...

in cylindrical and the creeping sole is narrow, occupying less than 25% of the ventral side. The cutaneous longitudinal

muscle Muscle is a soft tissue, one of the four basic types of animal tissue. There are three types of muscle tissue in vertebrates: skeletal muscle, cardiac muscle, and smooth muscle. Muscle tissue gives skeletal muscles the ability to muscle contra ...

s are very weak, not forming bundles. The parenchymal longitudinal musculature is very strong and forms an annular ring zone around the intestine. The copulatory apparatus has a well-developed penis papilla.
