DistributionNE Brazil, E Venezuela, Guyana, Suriname, Trinidad

Type locality: Agua Preta, Estado Pará, Brazil  
Reproductionoviparous 
TypesHolotype: USNM 158103, male (not 1581103 as in original description) 
DiagnosisDiagnosis. Chironius cochranae can be distinguished from its congeners by the following characteristics: (1) dorsal scale row arrangement is 12-12-10 in females, 12-12-8 in males (Fig. 4); (2) preocular single; (3) postoculars, two; (4) loreal present, single, rectangular; (5) temporals 1 þ 2; (6) supralabials 9, with fifth and six or four-six bordering orbit; (7) 10 lower labials, with first six in contact with chin shields; (8) ventrals 163–173 Trinidad (mainland 178–196) both sexes (9) paired subcaudals 156–172 both sexes, Trinidad (mainland 180– 199) both sexes; (10) juveniles brown with subtle transverse bands and a pale vertebral stripe; (11) adults dark blue-grey to black, first dorsal scale row olive-green with a dull yellow smudge; (12) vertebral stripe present between the keels on the paravertebral scales; (13) apical pits large and prominent on dorsal scales behind the head, and on the paravertebral scales and adjacent scales; (14) the first row of dorsal scales are quadrangular. Pale crossbands may be present on the otherwise brown dorsum of the anterior body in juveniles (Fig. 5). (Jadin et al. 2024)

CommentSynonymy: Chironius cochranae was described from a holotype from northeastern Brazil, near Belem and paratypes from Guyana and Suriname. However, one of the paratypes (AMNH 6801 from Guyana) was later found to be C. exoletus by Dixon et al. (1993). Abuys (1982) recognized C. cochranae as a subspecies of C. multiventris. This was followed by Dixon et al. (1993), who recognized four subspecies using morphology within C. multiventris: C. m. cochranae, C. m. foveatus, C. m. multiventris and C. m. septentrionalis. Dixon et al. (1993) assigned specimens from northeastern Brazil, Guyana and Suriname to C. m. cochranae. A phylogenetic analysis based upon Chironius morphological data provided by Dixon et al. (1993) was used as the basis for resurrecting C. cochranae (Hollis, 2006). Klaczko et al. (2014) synonymized C. cochranae with C. multiventris based on morphology, but the holotype of C. cochranae was not included in their study, nor were specimens from the type locality, nor any specimen from Guyana or Suriname. Jadin et al. 2024 resurrected cochranae from the synonym of multiventris. 
EtymologyNamed after Doris Cochran, American herpetologist at the USNM.
