Spathula is a genus of dugesiid triclad. Its species are found in Australia and New Zealand.
Until 1977, Spathula was ranked as a subgenus of Dugesia . [1] The name of the genus derives from the Latin spathula, meaning "broad, flat piece".
Specimens of this genus have a triangular head. [2] Along with this, the genus was originally defined as planarians with "one atrium (undivided) around the penis, into which opens the bursa stalk" and numerous testes. [3]
The following species are recognised in the genus Spathula [4]
Dugesia is a genus of dugesiid triclads that contains some common representatives of the class Turbellaria. These common flatworms are found in freshwater habitats of Africa, Eurasia, and Australia. Dugesia is best known to non-specialists because of its regeneration capacities.
Planariidae is a family of freshwater planarians.
Romankenkius is a genus of freshwater planarian in the family Dugesiidae.
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms.
Dugesiidae is a family of freshwater planarians distributed worldwide. The type genus is Dugesia Girard, 1850.
Girardia is a genus of freshwater planarians belonging to the family Dugesiidae.
Schmidtea is a genus of freshwater triclads. Species of the genus Schmidtea are widely used in regeneration and developmental studies.
Dendrocoelidae is a family of freshwater tricladida flatworms that has a holarctic distribution.
Dugesia notogaea is a species of dugesiid triclad that inhabits freshwater bodies of north Queensland, Australia.
Maricola is a suborder of triclad flatworms including species that mainly inhabit salt water environments. However, some species are also known from freshwater or brackish waters.
Dugesia aenigma is a species of dugesiid triclad that inhabits freshwater bodies of Cephalonia, Greece.
Kenkiidae is a family of freshwater triclads. Their species can be found sporadically in caves, groundwater, and deep lakes in Central Asia, Far East and North America.
Girardia tigrina, known as the brown planarian or the immigrant triclad flatworm, is a species of dugesiid native to the Americas. It has been accidentally introduced into Europe and Japan.
Cura is a genus of freshwater flatworm (triclad)s belonging to the family Dugesiidae.
Weissius capaciductus is a species of dugesiid triclad found in Australia. It is the only species in the monotypic genus Weissius.
Dimarcusidae is a family of triclads found mostly in freshwater habitats of caves, although at least one species, Rhodax evelinae, occurs in surface waters. Currently the family contains only seven species distributed in five genera, although the total number of species is thought to be much higher.
Neppia is a genus of dugesiid triclad that is found in South America, Subantarctic region, Africa, Tasmania and New Zealand.
Reynoldsonia reynoldsonia is a freshwater dugesiidae triclad found in Australia. It is the only species in the genus Reynoldsonia. It was named in honor of Professor Trefor B. Reynoldson.
Cura pinguis is a species of dugesiid triclad found in Australia and New Zealand.
Bothrioplana is a genus of freshwater flatworms, the sole genus in the family Bothrioplanidae and order Bothrioplanida.
