Diagnosis | Diagnosis (genus): The genus is characterized by a fused prefrontal shield.
Diagnosis. Chersodromus liebmanni can be distinguished from all Mexican species of snakes by having combination of prefrontals fused into single scale; postocular fused with supraocular; dorsal scales keeled in 17 rows at midbody, unreduced posteriorly; supralabials 7, third and fourth entering orbit; infralabials 7–8, usually 1– 5 contacting anterior chinshields (5 narrowly); mental contacting anterior chinshields; venter cream colored. This species may be distinguished from all species of Chersodromus, except C. rubriventris, by having the postocular fused with supraocular; from C. rubriventris by having 17 scales around body (vs. 15), ventral surface uniformly cream (vs. bright orange) (Table 1). Ninia diademata Baird & Girard (1853) might be confused with this species, and they are sympatric at some localities in Oaxaca and Veracruz. Ninia diademata differs from Chersodromus in having paired prefrontals shields, 19 strongly keeled dorsal scale rows, and two postoculars, larger body size (reaching at least 330 cm TL), and more slender tail. |
Comment | Synonymy after PETERS & OREJAS-MIRANDA 1970. Dixon & Ketchersid (1969) synonymized Schmidtophis with Chersodromus. According to Canseco-Márquez et al. 2018, Zweifel (1954), described C. nigricans from Guerrero, however, Scott (1967) placed this name into the synonymy of Tropidodipsas annulifera.
Type species: Chersodromus liebmanni REINHARDT 1861 is the type species of the genus Chersodromus REINHARDT 1861.
Mimicry: Chersodromus liebmanni mimicks Micrurus elegans (TORRE-LORANCA et al. 2006).
Distribution: Guatemala fide PETERS & OREJAS-MIRANDA 1970, but not in Guatemala fide KÖHLER 2008.
Conservation: IUCN category: least concern (LC) |
Etymology | The generic name comes from the Greek words cherso, meaning "earth," and dromus, meaning "a runner." |
