G. sanniolus reaches sexual maturity in eight months and produces a single clutch per year.[4]

Subspecies

Two subspecies are recognized as being valid, including the nominotypical subspecies.[2]

  • Geophis sanniolus neilli Henderson, Hoevers & Wilson, 1977

Etymology

The subspecific name, neilli, is in honor of American herpetologist Wilfred T. Neill.[5]
