DistributionUSA, Mexico (S Texas from Devils River and Starr County to C Tamaulipas and Nuevo León, Coahuila)

Type locality: Monterrey, Nuevo León.

cariniceps: Tamaulipas; Type locality: 8.1 km NE Gómez Farías, Rancho Pano Ayuctle along Río Sabinas.

plioporus: Gulf coast of Mexico from S Tamaulipas, Veracruz, Tabasco, southward to Petén, Guatemala. Type locality: Four miles east of Encero, Veracruz.  
Reproductionviviparous (ovoviviparous) 
TypesSyntypes: ANSP 11304-11305 (also given as USNM 31373-31377 but not in USNM catalog), collected by E. D. Cope
Holotype: UMMZ 101537 [cariniceps] 
DiagnosisDiagnosis (plioporus). Similar to serrifer serrifer, differing in average femoral pore count, the count on each thigh 9 to 14, average 11.9 (on both thighs, 20 to 27, average 23.8); dorsal scales smaller, average 31.7 (Smith 1939: 212). 
CommentSynonymy: MARTINEZ-MENDEZ & MENDEZ DE LA CRUZ 2007 synonymized Sceloporus serrifer plioporus with Sceloporus cyanogenys (although Wiens et al. 2013 say they did not). The original morphological difference between putative populations of S. s. plioporus and S. cyanogenys, was the divided supraoculars scales in the latter (Smith 1939). However, on closer inspection, these differences are not supported (Olson, 1987) because the percentage of individuals with divided supraoculars scales increases northwardly.

Distribution: endemic to Mexico fide Johnson et al. 2017, but reported from Texas by Dixon 2000 (map 66A). Not in Yucatan state (Mexico) according to GONZÁLEZ-SÁNCHEZ et al. 2017. Distribution: Not listed for San Luis Potosí by Lemos-Espinal et al. 2018 (checklist SLP).

Hybridization: C. serrifer and S. (s.) cyanogenys intergrade (OLSON 1987). 
EtymologyNamed after the Latin noun cyaneus "deep blue" and the Greek noun genys "jaw or chin" refer to the blue throat of males.

The subspecies plioporus was named after the Greek adjective plio, "more," and noun porus, "pore," refer to the larger number of femoral pores in this subspecies than in S. s. serrifer.
