Holotype: ZMH R20170 [Epicrates cupreus var. concolor] 
DiagnosisDiagnosis: Distinguished from all continental species of Epicrates by having: (1) lateral stripe of the body with four scales width, (2) irregular lateral ocelli in juvenile and indistinct in adults specimens, (3) dorsal ground color yellow to light brown in juveniles and uniform brown in adults, with noticeable ontogenetic change of coloration. Additionally, E. maurus differ from E. cenchria, E. assisi, and E. alvarezi by having hemipenis length (in situ). 13 subcaudal scales long; from E. cenchria and E. alvarezi, by having barely conspicuous parietal crest and reduced alary process of vomer; from E. cenchria, by having ventral scales, 245; from E. crassus, by having subcaudal scales generally . 50. Refer to Tables 6–7 for additional diagnostic features of the continental Epicrates. 
CommentSynonymy mostly after PASSOS & FERNANDES 2008.

Habitat: in open areas (savannahs) in Suriname. Semi-arboreal (Harrington et al. 2018).

Distribution: Not in Nicaragua fide Sunyer & Martínez-Fonseca 2023 (checklist Nicaragua). 
EtymologyNamed after Latin maurus, Greek μαυρός, darken, black; also Moor; inhabitant of North Africa; from Mauritania. (GRAY 1849, Esteban Lavilla, pers. comm., April 2024)
