Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/265983686/266019394

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.
