Assessment Rationale:

Orthonychiurus azoricus is an Azorean-endemic species described from S. Miguel island (Azores, Portugal) (Jacquemart, 1974), at an unknown location. Possibly it has a very small Extent of Occurrence (EOO = 4 km²) and Area of Occupancy (AOO = 4 km²); but the present situation of this species needs to be further assessed, and further research is needed into its population, distribution, threats, ecology and life history. Conservation of native habitats and streams could potentially aid this species' conservation. Based upon the lack of data regarding this species population, distribution, threats and ecology, this species is assessed as Data Deficient (DD).

Geographic Range:

Orthonychiurus azoricus is an Azorean-endemic species that was described from S. Miguel island (Azores, Portugal) but without indication of the location (Jacquemart 1974). It was never found after its description and consequently there is no precise indication of its location.

Current Population Trend: Unknown 

Habitat and Ecology

The ecology and traits of this species are unknown. According to the description, this species was collected under rocks in the volcanic sediment of a dry stream bed, in an undisclosed location.

Systems: Terrestrial 

Major Threat(s):

A lack of information regarding the present status of this species or its original location precludes an assessment of potential threats. Nevertheless, it can be assumed that past human disturbance and land use changes might have affected this species. Additionally, this species might be affected by future habitat declines as a consequence of climate change (Ferreira et al. 2016) and increased droughts 

Conservation Actions

The species is not protected by regional law. The present situation of this species needs to be further assessed and further research is needed into its population, distribution, threats, ecology and life history. Conservation of natural habitats and streams could potentially aid this species' conservation.
