Scientific Name: Suboestophora altamirai Ortiz de Zarate, 1962
Taxonomic Notes: This species was originally described as Oestophora (Suboestophora) tarraconensis altamirai, dedicated to Carlos Altimira. Martínez-Ortí (1999) proposed to correct this mistake by naming this species as S. altimirai.

Suboestophora altimirai
was considered a subspecies of S. tarraconensis. Based on anatomical studies of the reproductive system, the taxon has been raised to the species level (Martínez-Ortí 1995).

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2011
Date Assessed: 2010-09-06

This species is endemic to Castellón province, Spain, where is has a restricted Area of occupancy (AOO = 400 km2) and Extent of occurrence (EOO = 2,000 km2). It is known from only two locations. The main past and current threats are fires, urban expansion (housing), widening of roads and deforestation for road and path construction. These threats are causing a decline in the quality and extent of parts of its habitat, but not a continuous decline across all of its habitat. In the future fires and housing could potentially significantly affect this species and it is therefore listed as Vulnerable (VU D2).
