Etymology

The specific name, jarrovii, is in honor of Henry Crécy Yarrow (November 19, 1840 – July 2, 1929), an American ornithologist, herpetologist, naturalist, and surgeon.[2][3]

Geographic range

S. j. jarowii is found in the United States in the states of Arizona and New Mexico, and it is found in Mexico in the states of Chihuahua, Durango, Sonora, northern Tamaulipas, and western Zacatecas. The subspecies S. j. lineolateralis is found only in Mexico in the states of Durango and Zacatecas).[2]

Habitat

The preferred natural habitats of S. jarrovii are forest and rocky areas.[1]

Description

S. jarrovii grows to a snout-to-vent length of 10.5 cm (4.1 in) with keeled scales and a crosshatch-patterned torso. Its coloration includes tints of pink, green, blue, and copper. The top of the head is dark gray. Males have a blue throat and a blue belly. A complete black collar with a white inferior border distinguishes this lizard from similar species.[4]

Reproduction

S. jarrovii is viviparous.[2]

Subspecies

Two subspecies of S. jarrovii are recognized as being valid, including the nominotypical subspecies.[2]
