| Distribution | Lesser Antilles: Martinique Type locality: Unknown; restricted to Morne Capot, between Ajoupa-Bouillon and Le Lorrain, Martinique, by Lazell, 1964. |

| Diagnosis | Diagnosis (genus): Bothrops differs from other South American pitvipers in 50 mitochondrial characters (Table 4). In addition, Bothrops species generally have four palatine teeth, which is a morphological synapomorphy of the genus (B. moojeni and B. j South American genera by having higher numbers of ventrals (157–236 and 153–227, respectively, compared with 125–206), and by having the prelacunal fused to the second supralabial (also seen in Bothropoides jararaca, B. alcatraz, B. insularis, and in some Bothrocophias). Bothrops is distinguished from Bothriopsis in its brown to black coloration and lack of a prehensile tail, except for Bothrops osbornei and Bothrops punctatus with prehensile tails. These two Bothrops species occur west of the Andes, as opposed to Bothriopsis species that all range east of the Andes.araracussu have five; B. brazili and B. sanctaecrucis have three). Bothriopsis and Bothrops are distinguished from other South American genera by having higher numbers of ventrals (157–236 and 153–227, respectively, compared with 125–206), and by having the prelacunal fused to the second supralabial (also seen in Bothropoides jararaca, B. alcatraz, B. insularis, and in some Bothrocophias). Bothrops is distinguished from Bothriopsis in its brown to black coloration and lack of a prehensile tail, except for Bothrops osbornei and Bothrops punctatus with prehensile tails. These two Bothrops species occur west of the Andes, as opposed to Bothriopsis species that all range east of the Andes [from FENWICK et al. 2009]. |
| Comment | Venomous! Illustrations: see Lazell, 1964; Dowling, 1965; Pinchon, 1967; Gosner, 1987; Campbell and Lamar, 1989. Type species: Bothrops lanceolatus (Bonnaterre, 1790) is the type species of the genus Bothrops WAGLER 1824 (fide FENWICK et al. 2009). Species groups: Bothrops can be grouped into six evolutionary clades: B. alternatus clade, B. atrox clade, B. jararaca clade, B. jararacussu clade, B. pictus clade, B. neuwiedi clade, and B. taeniatus clade. For a phylogenetic analysis see Hamdan et al. 2019. Synonymy: Kaiser et al. 2013 considered the generic names Daraninus Hoser 2012, Jackyhoserea Hoser 2012 invalid and rejected their use instead of Bothrops. Conservation: one of the 30 most endangered viper species (Maritz et al. 2016). |
| Etymology | Named after Latin lanceolatus, a, um, ‘lanceolate’, lancehead shape. La Cepède (1789:121–122) called this species so because of the shape of the head (Fretey 2023). The generic name is derived from the Greek bothros, referring to the facial pit, and ops, meaning either ‘eye’ or ‘face’. It refers to the loreal pit between the nostril and eye, and names ending in this suffix are masculine. |
