| Comment | Synonymy partly after PETERS & OREJAS-MIRANDA 1970. Dixon 1983 placed Erythrolamprus oligolepis in the synonymy of Liophis reginae semilineata but CUNHA & NASCIMENTO 1993 revalidated it as Leimadophis oligolepis. Habitat: forest |
| Etymology | Named after Greek oligos (ὀλίγος), little, small, insignificant + Greek lepis (λεπίς), scale; epithelial debris (Esteban Lavilla, pers. comm., April 2024) |
