CommentSynonymy that of PETERS & OREJAS-MIRANDA 1970. Trachyboa nests within Tropidophis and was thus synonymized with it (Zaher et al. 2024)

Type species: Trachyboa gularis PETERS 1860 is the type species of the genus Trachyboa PETERS 1860, now a synonym of Tropidophis fide Zaher et al. 2024.

Habitat: partly arboreal (Harrington et al. 2018).

Abundance: Rare. This is one of the species called 'lost' and 'rediscovered' by Lindken et al. 2024. 
EtymologyNamed after Latin gularis, pertaining to the throat, neck or gullet. [“...eine gefleckte schwarze Querbinde von dem vordersten Frenalschild ausgehend, umgibt das Kinn vor der Kinnfurchengrube, eine zweite Binde geht vom unteren Augenrand aus und stößt V-förmig mit der der anderen Seite hinter der Kinngrube zusammen, und eine dritte dieser parallellaufend geht hinten vom Auge vor dem Mundwinkel an die Kehle...“]. (from Esteban Lavilla, pers. comm., May 2024)
