| Distribution | SE Mexico (Chiapas, Pacific versant of the Isthmus of Tehuantepec, Oaxaca, Jalisco). Type locality: Chihuitan, Oaxaca. |
| Reproduction | oviparous |
| Types | Lectotype: USNM 30310 (given as type by Smith & Taylor 1945, although there is a syntype, USNM 30311, too, which was interpreted as lectotype designation by Wallach et al. 2014). Other specimens: KU, UIMNH, FMNH, AMNH, UMMZ |
| Diagnosis | Diagnosis (genus): apparently not available; Cope described S. leucostomus as new species of a monotypic genus, so he did not provide a genus diagnosis. Gaige described the only other species in the genus as Eurypholis mayae, that is, in a different genus. Rossman & Schaefer 1974 moved Opheodrys mayae to Symphimus, without providing a revised diagnosis of the genus. Additional details (2178 characters) are available for collaborators and contributors.
