Specimen measurements are listed in Table 1 in Reynolds et al. 2016. Specimen squamation on the right side is as follows: 278 ventrals, 83 subcaudals, 14 supralabials, 1 loreal, 1 preocular, 1 suborbital, 4 postoculars, and 2 supraoculars. Paratype. MCZ R-193528. An adult male, obtained 21 October 2015. Found at night moving horizontally 2 m high on a B. simaruba branch. Specimen measurements are listed in Table 1. Specimen squamation on the right side is as follows: 278 ventrals, 83 subcaudals, 13 supralabials, 1 loreal, 1 preocular, 1 suborbital, 4 postoculars, and 1 supraocular. Preocular and sixth supralabial scales on the left side of the head are malformed, as is the fifth supralabial on the right side of the head.|
|Comment||Definition. A species of Chilabothrus boid snake possessing the following characteristics: silver to tan dorsal background coloration with or without scattered dark brown scales, which appear either individually or in small clusters; a reduced to absent dorsal pattern consisting of faint light-gray elongate dorso- ventral blotching, occasionally no pattern is obvious; pure cream-white ventral scales; a single loreal scale; ventral scale count ranging from 275 to 282; subcaudal scale count ranging from 82 to 91; a low number (11–12) of supralabials; 9–10 circumorbitals; largely arboreal substrate use; phylogenetic distinctiveness at mitochondrial locus CYTB consisting of . 3% pairwise divergence from other Bahamian Chilabothrus species.|
Habitat: This species is apparently largely arboreal, and has been found in Coco- thrinax argentata and B. simaruba.
|Etymology||The species name, argentum, is the nominative Latin word for silver, referencing the silver coloration of the first specimen encountered in July 2015 as well as its location in a silver palm (Cocothrinax argentata) when encountered.|
