CommentFor illustrations see Boulenger, 1885 (as Diploglossus striatus); Cochran, 1941 (as C.costatus); Grant, 1951 (as C. costatus); Schwartz, 1964 d.

Synonymy: Cochran (1941) synonymized Comptus stenurus with Panolopus costatus, along with numerous other species; however, this taxonomic action was not retained in later works (Schwartz 1970).

Subspecies: previous subspecies have been elevated to full species or synonymized with C. weinlandi.

Similar species: Comptus stenurus and C. weinlandi cannot be distinguished based on morphological characters; however, both of these species are morphologically distinct from their closest relatives (C. arboreus and C. alloeides, respectively). (Schools & Hedges 2024)

Type species: Diploglossus stenurus COPE 1862 (1863): 188 is the type species of the genus Comptus SCHOOLS & HEDGES 2021. Content. Three species: Comptus badius, C. maculatus, and C. stenurus.

Type species: Celestus striatus is the type species of the genus Celestus GRAY 1838: 288 (fide PETERS & DONOSO-BARROS 1970). Content (Cestesus s. str., fide Schools & Hedges 2021): 11 species: Celestus barbouri, C. crusculus, C. duquesneyi, C. fowleri, C. hewardii, C. macrolepis, C. macrotus, C. microblepharis, C. molesworthi, C. occiduus, and C. striatus.

Higher taxa: Celestus is here assigned to Diploglossidae based on the paraphyly within Anguimorpha in Zheng & Wiens 2016. Most other recent authors included the genus in Anguidae: Diploglossinae.

Conservation: While SCHOOLS & HEDGES 2021 considered Celestus striatus to be a valid species, it’s possible that the species has already gone extinct.

Habitat: Comptus and Panolopus have both ground and tree-adapted ecomorphs (Schools et al. 2022).

EtymologyNamed after Greek stenos = narrow, and possibly Greek oura = tail, for the relatively thin tail, Latinized to stenurus.
