DistributionMexico (Veracruz, Chiapas, Oaxaca, Yucatan, Campeche, Quintana Roo, Puebla), Guatemala, Honduras, El Salvador, Belize

Type locality: “Mexico”; restricted to “Tehuantepec, Oaxaca” by SMITH & TAYLOR 1950 [Sphaeriodactylus inornatus PETERS 1874]  
TypesSyntypes: USNM 6572 etc.
Lectotype: ZMB 36187, designated by HARRIS & KLUGE 1984 [Sphaeriodactylus inornatus PETERS 1874] 
DiagnosisDiagnosis: The combination of lacking moveable eyelids, having the dorsal surface of the head covered with granular scales, having the claws displaced laterallybytheexpandeddistalsubdigital lamellae, and having superciliary spines distinguishes Sphaerodactylus glaucus from all other Honduran lizards, except the remaining Sphaerodactylus. Sphaerodactylus glaucus is the only Honduran mainland species of the genus with smooth dorsal scales of equal size (McCranie 2018: 113). 
CommentDistribution: Not listed for Costa Rica by KÖHLER (2000).

Types: Harris & Kluge 1984: 32 conclude that USNM 6572 is the holotype of S. glaucus and that USNM 62995-96 and MCZ 13570 are not types, but rather the "several specimens" later referred to by Cope (1866:125). 
EtymologyThe name glaucus is Latin (bluish green or gray) and was used by Cope (1866a: 192) for his color description of the dorsal surfaces of the holotype as ‘‘greenish stone color or glaucus.’’
