Description

The genus Tasmanoplana is characterized by having an elongate, subcylindrical body that is flat ventrally. The creeping sole occupies more than two thirds of the body with. The eyes are small and arranged along the body margins in a single row from the anterior to the posterior end. The parenchymal musculature includes very strong and compact longitudinal fibers forming a ring around the intestine. The copulatory apparatus has a small penis papilla and a diverticulum ventral to the female atrium that opens into the copulatory canal.[1]

Etymology

The word Tasmanoplana is a combination of Tasmania, the island in which Charles Darwin collected the first specimen of the genus, and Latin plana, flat.[1]

Species

The genus Australoplana includes the following species:

  • Tasmanoplana balfouri (von Graff, 1899)
  • Tasmanoplana comitatis (Dendy, 1915)

gollark: My OS, obviously the best one, potatOS, runs on ANYTHING with ANY I/O which doesn't immediately crash!
gollark: I mean, that actually has a window manager and multitasking and stuff.
gollark: What's *not* novel, though? ANOTHER useless GUI thing because you want it to look "more like Windows" or something.
gollark: No, that would actually be novel.
