Species Authority: (Targioni-Tozzetti, 1881)
Common Name(s):
English – Southern Alpine Bush-cricket
Synonym(s):
Omalota apenninigena Targioni-Tozzetti, 1881
Taxonomic Source(s): Eades, D.C., Otte, D., Cigliano, M.M. and Braun, H. 2014. Orthoptera Species File. Version 5.0/5.0. Available at: Orthoptera.SpeciesFile.org.

Red List Category & Criteria: Critically Endangered (Possibly Extinct) B1ab(iii,v)+2ab(iii,v) ver 3.1
Year Published: 2016
Date Assessed: 2015-05-17
Assessor(s): Buzzetti, F.M., Hochkirch, A., Fontana, P., Kleukers, R., Massa, B. & Odé, B.

Justification:
The Southern Alpine Bush-cricket (Anonconotus apenninigenus) was described in 1881 on the basis of two specimens in the central Apennines, Italy. This species is assessed as Critically Endangered (Possibly Extinct) since it has not been found since 1881, despite intensive searches for it. In addition, its area of occupancy (AOO) and extent of occurrence (EOO) are both 4 km², it occurs at only one location, and there is an inferred continuing decline in the number of mature individuals and in the extent and quality of the habitat which was turned into forests after abandonment of pastures. However, this species might still be found in small patches of habitat and further research is recommended to clarify if the species is still extant.
Date last seen: 1881
Geographic Range [top]
Range Description: The Southern Alpine Bush-cricket is endemic to Italy, and is restricted to the central Apennines. This species is only know from two specimens collected in S. Ilario, La Consuma (Massa et al. 2012), and its area of occupancy (AOO) and extent of occurrence (EOO) are both 4 km².
Countries occurrence:
Native:
Italy (Italy (mainland))
Additional data:
♦ Estimated area of occupancy (AOO) - km2: 4
♦ Number of Locations: 2

Population [top]
Population: Only two specimens of this species have ever been collected. No further specimens have been collected since the species was described in 1881 despite searches for it. The overall population trend is therefore inferred to be decreasing.
Current Population Trend: Decreasing
Additional data:
Habitat and Ecology [top]
Habitat and Ecology: This species presumably lives in meadows.
Systems: Terrestrial
Movement patterns: Not a Migrant
Use and Trade [top]
Use and Trade:
This species is not utilised.
Threats [top]
Major Threat(s): The disappearance of this species has probably been caused by land use changes. Its habitat has completely been destroyed by transformation into forests after abandonment of pastures. Climate change might also have promoted its disappearance. Taking into account the extent of the destruction of its habitat and the restricted distribution of the species, it is considered to occur at only one location.
Conservation Actions [top]
Conservation Actions: There are no specific conservation measures in place for this species, and it does not occur in any protected areas. There have been substantial surveys to rediscover this species, but further searches should be carried out, as it might still survive in small patches of habitat.
