Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(v) ver 3.1
Year Published: 2013
Date Assessed: 2009-11-16
Assessor(s): Fitz Maurice, B, Sotomayor, M., Fitz Maurice, W.A., Hernández, H.M. & Smith, M.
Reviewer(s): Chanson, J.S. & Goettsch, B.K.
Facilitator/Compiler(s): Hilton-Taylor, C.
Justification:
As far as is known, this species has a very small extent of occurrence, certainly less than 100 km² and its area of occupancy may only be a few square kilometres. The species is very attractive and is highly sought after by collectors, although part of the population grows in inaccessible areas. Given its small range, the threat of collection, and that it is known from a single location, it is listed as Critically Endangered. If the population in the future is found to be more extensive and not as threatened, a lower category of threat may be warranted.

Geographic Range [top]

Range Description:This species is endemic to Mexico, and is found only in the southeastern part of the state of Coahuila on the Sierra Madre Oriental at elevations of around 2,000 m asl. The species is known only from two collections from the same location (Taylor 1985; note Taylor treats this incorrectly as two localities).
