DistributionNavassa Island

Type locality: Navassa Island.  
TypesHolotype: UMMZ 73630 
DiagnosisDESCRIPTION: Size small (SVL in males to 63 mm, in females to 53 mm); lateral postmentals 1/2-3/4 as wide as first infralabial, in contact with midline of mental; fourth finger lamellae 16-22; fourth toe lamellae 17-26; "friction pads" on 3 fingers and 2 outer toes. Dorsal pattern develops from juvenile dorsal "ladder"; dorsum tan, gray, yellow-brown to brown, with 6 wide, tan crossbands; dark stripe bordered with light margin from snout, across eyes, to sacrum in male and to shoulder in female; tail with about 9 narrow, dark crossbands, followed by light bands of same width; underside of tail dark (males), white (females); juvenile (SVL 20 mm) with 7 pinkish diamonds between neck and sacrum, 10 on tail; dark stripe from snout crossing eye and then broken to outline diamonds; general juvenile appearance decidedly checkered in contrast to "striped" adults; iris brown (from Schwartz & Henderson 1991: 360).

Diagnosis: “Aristelliger cochranae can be distinguished from the larger members of the genus (A. georgeensis, A. bechti, A. lar, and A. praesignis) by having multiple small, asymetrical adhesive plates adjacent to the claw on the digits rather than a single one on each manus and pes (see Nomenclatural History). This species may be distinguished from the other small member of the genus (A. barbouri) by the number of dorsal cross-bands, the number of loreal scales (generally > 15 in A. cochranaeand <16 in A. barbour), and the presence of a dark, sagittal longitudinal stripe running from the snout to the shoulder (absent in A. barbour).” (Lynxwiler & Parmerlee 1993)
