Assessment Notes
Justification
Stalpersia orientalis is known from its description in 2001 in the Sikhote-Alin Nature Reserve in Russia but has not been recorded since. Further research and targeted search efforts are needed to better understand its ecology, potential distribution and estimate the current population size. For now, the species is assessed as Data Deficient (DD).
Taxonomic notes
Stalpersia orientalis was described in 2001 as the type species of the monotypic genus
Stalpersia, based on morphological characteristics (Parmasto 2001).
Geographic range
It is known from the Sikhote-Alin Nature Reserve in Far East Russia (Parmasto 2001).
Population and Trends
Stalpersia orientalis was described based on specimens collected in 1987 and 1990 in two sites within the Sikhote-Alin Nature Reserve, but there have been no records of it since. It is not clear whether it is potentially rare, under-recorded or possible confused with other species, so it is not possible to estimate the population size and trends without further records or targeted search efforts.
Population Trend: Unknown
Habitat and Ecology
Specimens were found on forest litter in an
Abies forest and on rotten wood in a floodplain deciduous forest. Parmasto (2001) notes that
Stalpersia orientalis could be a mycorrhizal species, but this has not been confirmed.
Threats
Threats to this species are unknown.
Conservation Actions
Targeted search efforts and research into its ecology are needed to estimate the population size and potential distribution. A taxonomic review, namely through molecular analysis, could be useful to confirm its placement as a monotypic genus.
