Baja Sur Ground Snake

Subgenus Procinura
Sonora mosaueri
Stickel 1938
Near Loreto, Baja Sur, Mexico. September 13, 2015.

At the time this snake was detained and photographed, it resided in Sonora semiannulata, and I just took a couple one-off voucher photos. In 2018, Sonora was elevated to a ‘supergenus’ containing Chilomeniscus, Chionactis, and Sonora as subgenera. Sonora mosaueri is genetically closest to the file-tailed ground snake (Sonora aemula) in Sonora. For more information, see:
