Species[1] | |
Apodera is a genus of
protists belonging to the family Hyalospheniidae, a group of shelled amoebae. Their shells, or tests
, are lageniform with a clear constriction that separates the neck from the body.
Characteristics
Apodera are
euglyphid amoebae. This is a common trait among the Hyalospheniidae, to which Apodera belongs.[2] In particular, Apodera shells are uniquely distinctive by the presence of a clear, deep constriction that separates the neck from the body.[1][3]
Systematics
Apodera is a
Phylogenetic analyses also support a close relationship with Alocodera and Padaungiella, where Apodera is the sister group to a clade containing these two genera.[3]
There are four species of Apodera:
- Apodera angatakere (Brehm 1928) Mitchell, Blandenier & Duckert 2021
= Nebela penardi Brehm 1928
Found in peatlands of New Zealand, the shell has a distinctive hollow keel.[3]
- Apodera crenata Jung 1942
Problematic species with no bibliographic record after its first publication, although morphologically well defined and different from the type species by its curved shell and small size. Found only in Chile on Sphagnum mosses.[1]
- Apodera vas (Certes 1889) Loeblich & Tappan 1961
= Nebela vas Certes 1889
= Nebela goudinii Gericke 1932
= Apodera vas Jung 1942 nomen nudum
The type species, found in mosses such as Sphagnum, litter and organic soil. Its distribution is much wider than other species, with records from North America, South America, Oceania, Africa and Indonesia. A different form Apodera vas f. reticollaris was described by Jung in 1942, but it has not been proven with molecular methods.[1]
- Apodera wellingtonia Decloitre 1964
Rare and problematic species, found only once in two habitats. It was found in puddles of melting snow, and near rotten wood in wet lichens, in the island of Tasmania.[1]
