Reason: This endemic species has a somewhat large Extent of Occurrence of 13,220km2 however, it has a very small Area of Occupancy of just 7km2 and it is only known from five occurrences in the state. Furthermore, the species has not been seen anywhere since 1962 and so it is unknown whether the species is even still extent. On the other hand this species is small, hard to identify, and has not been widely surveyed for and may be much more abundant than is currently known. The life history and threats to this species are also currently unknown. However, the rapid warming and drying is a threat to many other perdita species. As a result, this poorly known species is currently assessed as S1 in New Mexico. However, a reassesment should be done if more information becomes available.
