Together with the dorsal zigzag Vipera latastei latastei also exhibits a series of round blotches on both flanks along the body. Each one of these blotches coincides with an interior edge of the zigzag pattern and they are of the same colour as the zigzag, only less contrasted. In the females these blotches are barely noticeable. In the intersection of the dorsal scales with the ventrals a second row of smaller and duller blotches can be observed, these coincide with the outer edges of the zigzag pattern.

Head: The colour of the head is usually very similar to the ground colour. Males tend to have a more ornate head than females, although the two characteristic crescent moon shaped marks at the back of the head are normally present in both sexes.

The postocular stripe on each side of the head begins at the eye and extends backwards touching the posteriormost supralabials. In some specimens it may extend along the sides of the body reaching the second or the third of the side blotches, drawing a well defined and elongated band.

Vipera latastei latastei males exhibit almost invariably two small dark triangular markings on the supralabial scales on both sides of the head.
The first marking is centred on the suture between supralabials 2 and 3, while the second marking is centred on the suture between supralabials 4 and 5. Females very rarely exhibit these supralabial markings.


Pholidosis: Dorsal scale rows number 21 (rarely 19 or 23). Males have between 130 and 142 ventrals, the average being 136 ventrals. Females have between 131 and 144 ventrals, with an average of 137.
