Comment | TANNER (1966) separated H. t. catalinae from H. torquata of the adjacent peninsula on the basis of the former having a single series of large dorsal spots, two rows of lateral spots, and a high number of ventral plus scutes (233-295). However, since these characters do not discretely diagnose catalinae GRISMER (1999) suggested to synonymize catalinae with H. torquata. MULCAHY (2008) considered catalinae as a valid subspecies (of Hypsiglena chlorophaea). Mulcahy et al. 2014 elevated Hypsiglena chlorophaea catalinae TANNER 1966 to full species status. Distribution: see map of subspecies in Mulcahy et al. 2014. Not in Sinaloa fide D. Mulcahy, pers. comm., 1 Feb 2020. |
