TypesHolotype: IBSP (= IB) 23397. 
DiagnosisDiagnosis: Bothrops moojeni is distinguished from all congeners and from species of Bothrocophias and Bothriopsis by the following combination of characters: (1) lacunolabial present; (2) dorsal keels nontuberculate; (3) infralabials and gulars immaculate; (4) canthorostrals absent; (5) subcaudals divided; (6) ventrals 179–210 and subcaudals 44–70 (Campbell and Lamar 1989); (7) loreal subtriangular; (8) canthals narrow and separated by 4–7 scales; (9) internasals in contact (33%, 9) or separated by 1–2 scales; (10) postocular stripe absent or dark brown to gray and narrow: less than one temporal high; (11) dorsum gray to brown, pattern of subtriangular blotches; venter cream with very diffuse if any pigmentation except on edges; distinctive wavy occipital stripe extending onto neck (Harvey 2005: 19) 
CommentVenomous!

Synonymy: May be conspecific with B. atrox.

Distribution: See map in Harvey 2005: 14 (Fig. 9). See map in Nogueira et al. 2019. 
EtymologyNamed after Dr. Joao Moojen de Oliveira (1904-1985), a Brazilian zoologist who collected extensively from the 1930s to the 1950s.
