Newzealandia is a genus of land planarians from the New Zealand.
Species of Newzealandia are characterized by a copulatory apparatus that lacks a penis papilla and has a series of accessory glands embedded into the wall of the atrial cavity. [1] Those glands are similar to the adenodactyls found in the closely related genus Artioposthia , the main difference being that adenodactyls project into the atrial cavity. [2]
The name Newzealandia comes from New Zealand, the country in which the species of the genus are found.
The genus Newzealandia includes the following species:
The New Zealand flatworm is a large land flatworm native to New Zealand. It can vary from 5 mm in length when hatched to approximately 17 centimetres (6.7 in) in mature adults.
Bipalium is a genus of large predatory land planarians. They are often loosely called "hammerhead worms" or "broadhead planarians" because of the distinctive shape of their head region. Land planarians are unique in that they possess a "creeping sole" on their ventral side. Several species are considered as invasive to the United States and to Europe. Some studies have begun the investigation of the evolutionary ecology of these invasive planarians.
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region.
Luteostriata is a genus of land planarians from Brazil characterized by a yellow body with dark longitudinal stripes.
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity.
Choeradoplana is a genus of land planarians from South America.
Caenoplana is a genus of land planarians from Australia and New Zealand.
Arthurdendyus is a genus of land planarians from New Zealand.
Marionfyfea is a genus of land planarians from Antarctic Islands off New Zealand. However, a species has been described from specimens found in Europe, probably introduced.
Anzoplana is a genus of land planarians from Australia, currently comprising a single species, Anzoplana trilineata.
Australoplana also known as Australian flatworm is a genus of land planarians from Australia and New Zealand.
Kontikia is a genus of land planarians native from islands in the Indo-Pacific region, but several species have been introduced elsewhere.
Timyma is a genus of land planarians that currently contains a single species, Timyma juliae. The species was found in Chile, but its anatomic features indicate that it is probably introduced in South America, being native from somewhere in the Pacific.
Pimea is a genus of land planarians that currently contains a single species, Pimea monticola, from the central highlands of New Caledonia.
Artioposthia is a genus of land planarians from the Australasian and Indo-Pacific countries. Several species have also been introduced in Europe.
Coleocephalus is a genus of land planarians that currently contains a single species, Coleocephalus fuscus, from the Enderby Island, New Zealand.
Reomkago is a genus of land planariansş from Australia.kşizsö
Fletchamia is a genus of land planarians from Australia.
Lenkunya is a genus of land planarians from Australia.
Geobenazzia is a genus of land planarians that currently contains a single species, Geobenazzia tyrrhenica, found in Elba, Italy.
