Reason: Ceryonis meadii alamosa also known as the Alamosa Satyr is found in a small range in and around Colorado's San Luis Valley south to the Taos plateau. This taxas population size and trend are unknown however some estimates indicate that the parent species may be declining. This taxa has a very small Extent of Occurrence (EOO) and Area of Occupancy (AOO) however, these may be underestimated due to a lack of surveying and poor phenotypic differentiation. This species has several potential threats, the most prevalent of which is climate change. However, the species is also threatened by invasive species, grazing, and fire suppression. Being all in one valley this taxa exists in just one occurrence where one drought could affect the entire area at once. As a result, this butterfly is currently assessed as S1 in New Mexico however, with so many things still being unknown about this species a reassessment should be done if more information becomes available.

Ecological Factors
Specificity: Narrow. Specialist or community with key requirements common.	Range Extent: <100 square km (less than about 40 square miles)
Occurences: 1 - 5	Population Size: Unknown
Area of Occupancy: In New Mexico there is currently only one known occurrence record which was made at the Chaua Lama Overlook on the east side of the Rio Grande Gorge along the Chiflo trail. However, this subspecies is poorly phenotypically differentiated and recorded and may be more widespread than is currently thought.	Threat Summary: N/A
