| Distribution | Ecuador (Amazonas) Colombia Type locality: “America meridionale”. |
| Reproduction | oviparous |
| Types | Holotype: MRSN (= MSNTO = MZUT) R257 |
| Diagnosis | Diagnosis (genus): Colubrid snakes with keeleddorsal scales, without apical pits, arranged in 23 to 21 rows anteriorly, normally, but not always (with the loss of the 4th row or its fusion with the 5th) diminishing in number to 2l or 79 at midbody and to 21, 19 or 17 at the vent; keels, less strongly developed in the lateral rows of scales,may be lacking on those contiguous to the ventrals. Anal plate and prefrontal undivided, loreal present or absent, nasal single or divided. Hypapophyses present on vertebrae throughout the trunk. The hypapophysis extends to an apex that projects beyond the centrum; preygapophyses and postzygapophyses greatly expanded and united, thus forming parallel lateral edgeson the vertebrae. On the vertebrae of adults the neural spine is expanded and flamened, with a median groove on a crest that extends forward to paired extremities projecting above the zygosphene. Maxillary teeth 27 to 27, two or three at the rear slightly enlarged but not separated by a diastema. Hemipenis extending to level of 6th or 7th caudal, distally bifurcate, the division of the sulcusat the level of the 4th or 5th caudal. Spines in approximately six rows, enlarged and hook-like near the base, but diminishing in size distally, and replaced by calyces with crenulated edgeson the lobes. Pupil round. [BOGERT 1964: 515] |
| Comment | Synonymy: Amaral (1929) considered the holotype of Synophis bicolor (at the time the only known specimen from the only known species) to be synonymous with Diaphorolepis wagneri. Diet: gymnophthalmid lizards (Pyron et al. 2016). Type species: Synophis bicolor PERACCA 1896 is the type species of the genus Synophis PERACCA 1896. S. bicolor was split into 4 species by TORRES-CARVAJAL et al. 2015. |
| Etymology | None given by Peracca (1896); the Greek “syn-” means “with” or “together” and ophis means “snake”. The species name is presumably from the Greek bi-color for “two colors,” referring to the dark dorsum and light venter. Some dictionaries called this species “Two-colored Fishing Snake” but there is no evidence this species eats fish (Pyron e al. 2016). |
