Range Extent200,000-2,500,000 square km (about 80,000-1,000,000 square miles)
Number of Occurrences21 - 300
Rank Reasons
This species has a fairly broad range from Arizona, US, to central Mexico and is likely known from a large number of occurrences. Threats to this species are not known, however it may be affected by climate change.
Range Extent Comments
This species ranges from south-central Arizona, US, to Nayarit, Mexico, along the coastal plain.
Occurrences Comments
There are approximately 30 extant occurrences in Arizona and this species is known from several localities along the western coast of Mexico. It was recognized as distinct from G. olivaceae in 2012, therefore additional sampling is needed to understand species boundaries and determine the number of occurrences.
Threat Impact Comments
No major threats have been identified for this species. However global climatic changes can affect seasonal arid cycles in parts of its range and it may be vulnerability to environmental degradation (Wilson et al. (2013).
