DiagnosisOriginal description (COPE 1885): Scales of the back in nearly parallel series, twelve of them equaling the length of the head, keeled and mucronate. Two canthal scales. Anterior frontal not longitudinally divided. Supraoculitr scales in two larger rows, of which the inner contains four or five scales, and the outer three or two shorter ones. One parietal scale. All the head scales smooth. Scales of sides equal dorsals, their keels directed upwards and backwards; those of belly smaller and entire. Thirteen femoral pores. Color above bluish olive, with numerous small irregular black spots. A vertical black spot rises vertically from the shoulder, and is separated from that of the opposite side by a space equal to its length. Inferior surfaces brassy, the sides blue-tinged in front of the groin; chin blue; no black collar on throat or nape. Two black bands, separated by a brown one on the posterior face of the thigh.
Length of head and body to vent, M. .040; length of head to line of auricular meatus, .0ll; length of posterior leg, .030; of posterior foot, .016; of tibia, ,008. 
CommentSynonymy: Has been synonymized with S. formosus smaragdinus by SMITH 1939. Not listed for Mexico by KÖHLER (2000).

Group: S. formosus group (sensu lato, fide PÉREZ-RAMOS & SALDAÑA DE LA RIVA 2008) 
EtymologyThe Latin taenia, "band" or "ribbon", and the Greek kneme, meaning "leg between knee and ankle", refer to the "two black bands, separated by a brown one, on the posterior face of the thigh." The chosen Greek word for the species name is incorrect, but immutable.

hartwegi: The Latin nominative singular noun honors the late Norman E. Hartweg, former staff member at the University of Michigan Museum of Zoology, who worked extensively on the herpetology of Oaxaca and Chiapas.
