|Comment||Diagnosis.—Corallus ruschenbergerii is easily distinguished from all other species of Corallus except C. grenadensis. The maximum number of dorsal scale rows in C. cropanii is fewer than 35 (38–48 in C. ruschenbergerii). Corallus annulatus, the only congener with which there is significant sympatry, has a maximum of 50–57 dorsal scale rows and only 79–87 subcaudals (94–115 in C. ruschenbergerii). Corallus caninus has a maximum of 63–77 dorsal scale rows, and 186–209 ventrals (250–272 in C. ruschenbergerii). With very few exceptions, C. hortulanus from mainland South America and Ilha Grande off southeastern Brazil have 50 or more maximum dorsal scale rows (individuals from Guyana, Suriname, Peru, and Bolivia rarely have 47 or 48) and color and pattern are extremely variable.|
Corallus from St. Vincent and the Grenada Bank are the shortest and most slender of the Neotropical tree boas, and this can be related to aspects of their ecology (see below). They exhibit great overlap in lepidosis with C. ruschenbergerii, but C. ruschenbergerii is much larger (maximum SVL in West Indian Corallus is 1625 mm), and C. grenadensis exhibits tremendous color and pattern variation. Despite the pattern variation in the West Indian populations, none of it duplicates that found in C. ruschenbergerii, with the exception of yellow-brown individuals that have no discernible pattern [from HENDERSON 1997].
Max. total length: 2.5 m.
