Rank Reasons

This species is endemic to New Mexico where it apparently occurs in a limited number of occurrences.

Range Extent Comments

This species is an endemic to New Mexico, USA, and known from north west of Sante Fe in the Jemez Mountains and Sulphur Springs area to the southwest to the Alamo Heuco Mountains in Hidalgo County (NHNM 2022, Wallace 2021). The range extent is approximately 86,000 km2 based on known records as of November 2022, including historical records.

Occurrences Comments

There are four mapped occurrences and eight other known locations of this species (NHNM 2022). Further surveys of suitable habitat are likely to result in some more occurrences.

Threat Impact Comments

The general threats for this species in Lang (2000 and 2005) are listed as: natural system modification (fire and deforestation), energy production and mining, transportation and service corridors (road and building construction) and residential and commercial development. The impact and scope of these threats are unknown.
