Originally described as Secotium arizonicum and also known as Endoptychum arizonicum. Possibly a complex of cryptic species (Loizides et al. 2020).

This species appears to be seems restricted to xeric regions of North America. Small population, many records old and localities should be revisited. No data on population trends.  Potentially belonging to a complex of cryptic species. Suggested assessment: DD

Recorded from dry and xeric areas in the United States (Arizona, Texas). and Mexico. Reports from Argentina and Italy need to be verified. An eDNA sample submitted to GenBank under this name from Kazakhstan does not fully match the type sequence of C. arizonicum.  It could be assumed that its distrubution is restricted to arid regions of N. America.

No data on current trends. 112 records in GBIF database. However many of the records are old.

Dry grazed grassland, xeric sandy habitats and arid steppe vegetation.

Old records should be reviewed and localities revisted to get a clearer picture of threats and trends. Loizides et al (2020) reports the presence of two unnamed sister clades indicating a complex of cryptic species. This complex should be resolved using molecular and morphological methods.
