Assessment Rationale:

The Gran Canaria Bush-cricket (Evergoderes cabrerai) has not been found since 1966 despite searches during the last years. It is only known from one locality (Barranco de Agaete, Gran Canaria), but its habitat is unknown. A continuing decline has probably affected the number of mature individuals, and the number of locations has been estimated as one. The species is therefore assessed as Critically Endangered (CR). While it is possibly extinct, further searches are planned for the future.

Geographic Range:

The Gran Canaria Bush-cricket is endemic to the Barranco de Agaete, Gran Canaria (Canary Islands) (Bland et al. 1996).

Biogeographic Realms:

The species has not been found since the mid-1960s, and it is not clear if it is extinct. Despite the fact that recent searches have been undertaken (H. López pers. comm. 2011, A. Miller pers. comm. 2013, D. Margaritis pers. comm 2014), no individuals have been found. The population trend is assumed to be decreasing.

Habitat and Ecology

The habitat of this species is unknown, but it may have occurred in bushes or trees.

Major Threat(s):

The reasons for its decline are unknown, although it may have been possibly caused by human land use and rural development. It may also be affected by the increasing frequency of wildfires or by landslides. Based on any of these threats, the species is present in only one location.

Conservation Actions

There are no conservation actions in place for this species, and the area is not protected. An intensive search for this species would be necessary to clarify if it may have survived in small patches of the barranco. If the species is rediscovered, its ecology needs to be studied in order to apply the most appropriate habitat management. Further research is also needed on its population size and trends and threats to the species
