Notes
References:
The distribution map on this page is referred to as the 2024 distribution map.
Usually only species from North America north of Mexico are added to SINA. This species, only known from Baja California, Mexico, has been added because it was part of a large revision of the Aglaothorax genus that was added to SINA in late 2025, early 2026.
All records are from Cole et al. (2025). [tmy 11 January 2026]
