Assessment Rationale:

The Canarian Crevice-cricket occurs under stones in the forest zone of Tenerife and La Palma (Canary Islands, Spain). The species occurs in protected areas, but it is difficult to find because it lives under stones and does not produce any sound. Therefore, there is insufficient knowledge of its population size or trend. The extent of occurrence (EOO) is c.3,500 km². As the species is flightless and subpopulations appear to be small, the population is considered severely fragmented. The species is therefore assessed as Near Threatened as it nearly meets the thresholds for a threatened Category.

Geographic Range:

The Canarian Crevice-cricket is endemic to Tenerife and La Palma (Bland et al. 1996), where it mainly occurs at higher elevations in forested areas. Its extent of occurrence (EOO) is c. 3,800 km².

There is no information available on the population size and trend of the species. The species is flightless and subpopulations appear to be small, and may go extinct with a reduced probability of recolonization. The population is therefore considered to be severely fragmented.

Habitat and Ecology

The species has mainly been found in forests, where it lives under rocks and debris.

Major Threat(s):

Natural threats to this species are active volcanism and landslides, but threats from human activities are unknown.

Conservation Actions

There are no specific conservation actions in place for this species, although it occurs in protected areas throughout its range. There is a need for research on its taxonomy, population trends and ecology.
