It is characterized by having 10 to 15 dark spots above the light dorsolateral band, from the area of the tympanum to the beginning of the tail. This differentiates it from the similar species Teius suquiensis, which has between 16 and 22 dark spots above the light dorsolateral band.

Identification Key for Teius:

1a) Above the light longitudinal dorsolateral band, there is a series or row of irregular dark spots, often anastomosed, that generally cannot be counted with certainty. Adult males with a bright blue belly: Teius teyou.
1b) Above the light longitudinal dorsolateral band, there are individually recognizable dark spots, generally rectangular, square, or triangular in shape, which can be relatively easily counted: 2)
2a) 10 to 15 dark spots along the light dorsolateral line, counting from the region above the tympanum to the base of the tail: Teius oculatus (both males and females can be observed).
2b) 16 to 22 dark spots along the light dorsolateral line, counting from the supratympanic region to the base of the tail: Teius suquiensis (only parthenogenetic females).
