| Comment | Subspecies: PETERS 1957 doubts the validity of Corallus annulatus colombianus (RENDAHL & VESTERGREN 1941) [fide STIMSON 1969]. Corallus annulatus blombergi (RENDAHL & VESTERGREN 1941) is now treated as valid species. Note that this species is quite variable with grayis, brownisch, and redish forms (WIRZ 2004). Distribution: not in Ecuador (fide TORRES-CARVAJAL, pers. comm., 13 Feb 2012). See also MCDIARMID et al. 1999. Reproduction: viviparous Etymology: Named after the diminutive form (“annul-”) of Latin “anus” = ring. Diagnosis: Corallus annulatus is distinguishable from members of the C. hortulanus complex (C. cookii, C. grenadensis, C. hortulanus, C. ruschenbergerii) by the combination of presence or absence of nasal contact (usually contact in C. hortulanus complex, usually not in C. annulatus) and number of sub-caudals (94–137 in C. hortulanus complex, 79–88 in C. annulatus). It is distinguishable from C. cropanii on the basis of maximum number of dorsal scale rows (<35 in C. cropanii, 50–57 in C. annulatus), and from C. caninus by the maximum number of dorsal scale rows (63–77 in C. caninus), and ventrals (251–268 in C. annulatus, 186–209 in C. caninus). It differs from C. blombergi in dorsal ground color (usually beige to red-brown in C. annulatus, usually milk chocolate brown to rich dark brown in C. blombergi); dorsal blotches 6–12 (usually 9–10) scales wide at midbody in C. annulatus [6–9 (usually 7–8) in C. blombergi]; central area of dorsal blotches more or less same shade as dorsal ground color in C. annulatus (distinctly paler than dorsal ground color in C. blombergi); infraloreals + loreals usually 8–9 in C. annulatus (usually 6 in C. blombergi); anterior edge of splenial hooked in C. annulatus (gradually tapering anteroventrally in C. blombergi); and coronoid in contact with the angular in C. annulatus (separated in C. blombergi) [HENDERSON et al. 2001]. |
