- Trimeresurus sabahi sabahi Regenass & Kramer, 1981 – northern Borneo (Malaysia)
- Trimeresurus sabahi toba David, Petri, Vogel & Doria, 2009 – Sumatra
IUCN treats these as full species, respectively Trimeresurus barati,[5] Trimeresurus buniana,[6] Trimeresurus fucatus,[7] and Trimeresurus toba,[8] restricting Trimeresurus sabahi to the nominotypical subspecies.[1]
Description
editAdults may attain a snout-vent length (SVL) of 62 cm (24 in).[9]
Dorsally, it is uniform green, without crossbars. Ventrally it is pale green. There is narrow bicolor stripe on the first one and a half dorsal scale rows. In males this stripe is rust-colored or red below, and it is white above. In females it is yellow or white. The iris of the eye is red or orange in adults of both sexes, but in young specimens may be yellowish-green. There are no markings behind the eye.[9]
The scalation includes 21 (23) rows of dorsal scales at midbody, 149–157/148–156 ventral scales in males/females or 148–159 in general, 72–76/59–65 subcaudal scales in males/females, and 9–11 supralabial scales (9–10 with the third being the largest).[4]
Habitat
editIn Borneo, it inhabits mountainous regions at altitudes from 1,000 m (3,300 ft) to 1,150 m (3,770 ft), where it is commonly found on branches of shrubs and other low vegetation.[9]
Reproduction
editThe reproductive biology of this species is unknown.[9]
