DistributionMexico (E Coahuila, C/N Nuevo Leon)

lateralis: Type Locality: San Diego, Duval County, Texas, in error; the species is restricted to Mexico. The type probably came from somewhere in Nuevo León (BELL et al. 2003)

Type locality: Santa Catarina, Nuevo León  
Reproductionoviparous 
TypesLectotype: USNM 2739b, selected from a series of 9 specimens under the same number, by Smith (1939); Lieut. Darius Nash Couch collector, April 1853.
Holotype: USNM 14741, a typical S. couchi, collected by W. P. Taylor; given as USNM 2739 by Dickerson 1919: 468 [lateralis] 
DiagnosisDiagnosis: Smith 1939: 240 
CommentDistribution: Not listed by CROTHER 2000, 2017 for the USA.

Type species: Lysoptychus lateralis is the type species of the genus Lysoptychus COPE 1888

Synonymy: Lysoptychus was not recognized by herpetologists and Cope’s specimen has been referred to Sceloporus couchii Baird (type,,fromSanta Catarina, Nuevo Leon, Mexico) (Stejneger and Barbour, 1917, Check List, p. 53). 
EtymologyThis Latin noun in the genitive singular honors Lieut. Darius Nash Couch (1822-1897), the collector. See Conant 1968 for more biographical details.

lateralis: The Latin adjective lateralis, "of the side," probably was based on the very prominent lateral dark and light stripes.
