This species is endemic to northeastern Spain, where it is known from at least 15 caves. The current or potential threats at the known localities are uncertain and require research. The species is assessed as Near Threatened (NT B1a+2a) on the basis of the restricted area of occupancy and extent of occurrence.
|Range Description:||This species is known from 15-16 caves in the Sierra de Aramot and the Montes de Triano, Bizkaia, northeastern Spain (Gómez and Prieto 1983, Prieto et al. 2011, C.E. Prieto unpublished data 2017).|

|Population:||Due to the small size and subterranean occurrence of this species, nothing is known about the current population trend.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:|
This species is found in the interior parts of the cave (Prieto et al. 2011). Members of this genus are found on moist cave walls (Jochum et al. 2012).
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Use and Trade:||The species is not utilized.|
The type locality cave is in a mountain area, and whilst it is known by local people, it is only rarely visited by speleologists (C.E. Prieto pers. comm. 2016). Prieto et al. (2011) suggest that conifer afforestation around the type locality cave may result in changes to the interior conditions of the cave, but this requires further research and monitoring, and nothing is known of threats at the other caves where it is recorded.
|Conservation Actions:||The species has been assessed as Vulnerable (VU) in Spain (Verdú et al. 2011). Research has shown that this species has a much wider contribution and is not restricted to a single cave, the type locality. Monitoring of all cave environments is recommended.|
