| Diagnosis | Diagnosis (tribe). A group of relatively small-sized (<550mm SVL), slender, lizard-eating dipsadid snakes restricted to the Darien of Panama and northern Andes of South America, diagnosable from all other similar or related species by possessing fused prefrontals and either an expanded intervertebral scale row (Diaphorolepis) or expanded zygapophyses and neural spines in adults (Emmochliophis and Synophis; Pyron et al. 2016).

| Comment | HILLIS 1990 incorrectly identified a Diaphorolepis wagneri as D. laevis. Type species: Diaphorolepis wagneri JAN 1863 is the type species of the genus Diaphorolepis WERNER 1901. WERNER 1901 states that JAN did not describe the genus and that the name was a nomen nudum. Type genus: Diaphorolepis Jan 1863 is the type genus of the tribe Diaphorolepidini Pyron et al. 2016 which contains Diaphorolepis Jan, 1863, Emmochliophis Fritts & Smith, 1969, Synophis Peracca, 1896. Note that "Diaphorolepidini was already described by Jenner, 1981" but her Diaphorolepidini is not an available nomen fide Pyron et al. as it was described in an unpublished PhD thesis. Taxonomy: Diaphorolepis Jan, 1863 is also the type genus of the tribus Diaphorolepidini Jenner, 1981. The tribe name has also been spelled ‘Diaphorolepini’ by Sheehy (2012), but Diaphorolepidini is the correct spelling. Pyron et al. 2015 restricted the Diaphorolepidini to the genera Diaphorolepis, Emmochliophis, and Synophis, compared to the original description (Jenner 1981), which included Atractus, Chersodromus, Crisantophis, Elapomorphus, Enulius, Gomesophis, Pseudotomodon, Ptychophis, and Sordellina. Habitat: not arboreal (Harrington et al. 2018). |
| Etymology | The species is most likely named after Moritz Wagner, not after Johann Andreas Wagner as stated in Boelens et al. (2011) [Bauer 2013, HR 44: 703]. The genus was named after the Greek diaphoros for “differentiated” and lepis for “scales,” likely referring to the enlarged vertebral scale row as compared to the rest of the dorsal scales. |
