Anzoplana is a genus of land planarians from Australia, currently comprising a single species, Anzoplana trilineata. [1]
The genus Anzoplana includes land planarians of the tribe Anzoplanini that have a small and robust body, with mouth just behind the mid body and gonopore closer to the mouth than to the posterior end. The mesenchymal longitudinal musculature is weak, not forming clear bundles, but forming a weak ring zone around the intestine and a well-developed subneural plate. The copulatory apparatus has an eversible penis, without papilla, and adenodactyls. [1]
The name Anzoplana comes from ANZ, a traditional abbreviation for Australia and New Zealand, combined with Latin plana, flat. [1]
The flatworms, flat worms, Platyhelminthes, or platyhelminths are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates, and have no specialised circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both ingestion and egestion ; as a result, the food cannot be processed continuously.
A planarian is one of the many flatworms of the traditional class Turbellaria. It usually describes free-living flatworms of the order Tricladida (triclads), although this common name is also used for a wide number of free-living platyhelminthes. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers. Some species are terrestrial and are found under logs, in or on the soil, and on plants in humid areas.
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.
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms.
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", a highly ciliated region on the ventral epidermis that helps them to creep over the substrate. Native to Asia, several species are invasive to the United States, Canada, and Europe. Some studies have begun the investigation of the evolutionary ecology of these invasive planarians.
Cura is a genus of freshwater flatworm (triclad)s belonging to the family Dugesiidae.
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. Members of this family are sometimes referred to as the Neotropical land planarians. However, one species, Obama nungara has been introduced in Europe.
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity.
Caenoplana is a genus of land planarians from Australia and New Zealand.
Arthurdendyus is a genus of land planarians from New Zealand. It was erected in 1999 and includes the invasive species Arthurdendyus triangulatus, known as the New Zealand flatworm.
Anzoplanini is a tribe of land planarians in the subfamily Rhynchodeminae.
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.
Marionfyfea adventor is a species of land planarian described in 2016 from specimens found in the United Kingdom, the Netherlands and France. However, since the species belongs to the genus Marionfyfea, of which the species are known only from subantarctic islands off New Zealand, it is probably an introduced species in Europe.
Australoplana also known as Australian flatworm is a genus of land planarians from Australia and New Zealand.
Timyma is a genus of land planarians from Chile. It is the sole genus of the subfamily Timyminae.
Reomkago is a genus of land planarians from Australia.
Fletchamia is a genus of land planarians from Australia.
Pelmatoplaninini is a tribe of land planarians in the subfamily Rhynchodeminae.
Eudoxiatopoplana is a genus of land planarians from New Zealand, currently comprising a single species, Eudoxiatopoplana bilaticlavia, that occurs in Stewart Island. It is the sole genus of the tribe Eudoxiaotopoplanini.
Argaplana is a genus of land planarians, the only member of the tribe Argaplanini in the family Rhynchodeminae. It contains the sole species Argaplana ranuii. It is native to New Zealand.
