Reproduction | oviparous |
Types | Holotype: MNHN-RA 6203, male, collected by Dr. Viguier. |
Diagnosis | The characters that Peters (1960a) used to distinguish D. viguieri and D. gracilis (e.g., preocular presence/absence, number of postoculars) are known to be highly variable intraspecifically within Dipsas. Peters (1960a: 52) considered the two perhaps only ‘‘subspecifically distinct’’ and otherwise noted (Peters, 1960a: 48) that ‘‘The characters separating [Dipsas gracilis] and D. viguieri are comparatively weak ones. . . .’’ Thus, specimens of D. viguieri will key out to D. gracilis with the key in Cadle 2005. |
Comment | Synonymy partly after PETERS & OREJAS-MIRANDA 1970. Dipsas gracilis and D. viguieri are not distinguishable according to CADLE (2005) and Harvey (2008). Habitat: fully arboreal (Harrington et al. 2018). |
Etymology | named after the collector of the types, Dr. Viguier. |
