Type­locality. “ Mexico.” The type locality of R. guttulatum Cope is “Vera Cruz.” Distribution. Known only from Mirador, Veracruz, Mexico, ca. 1150 m elevation. Species group. chalybeus ( Downs 1967) .

Systematic references. Wagler (1830), Peters (1859), Cope (1885), Günther (1893), Boulenger (1894), Cope (1900), Amaral (1929), Slevin (1939), Smith (1941a), Downs (1967).

Remarks. Smith (1941a) placed Rhabdosoma guttulatum Cope in synonymy with G. chalybeus , as R. guttulatum agrees with the descriptions of G. chalybeus supplied by Wagler (1830) and Peters (1859). Downs (1967: 36–40) tentatively accepted this concept of G. chalybeus while detailing the confusing taxonomic history of this species.
