Diagnosis | Diagnosis: “Sordellina punctata can be recognized by having (for additional characters, see Hoge and Romano, 1978; Miranda and Fernandes, 2012): (1) usually eight supralabials; (2) 17/17/17 dorsal scale rows, with no apical pits; (3) head dark brown in dorsal view with supralabials mottled with white or yellow; (4) dorsum uniformly dark brown to black; (5) hemipenis slightly bilobed, the lobular region covered by papillae with little or no tissue interconnection; (6) 11–14 prediastemal maxillary teeth and two postdiastemal teeth; (7) dorsolateral crests of the parietal conspicuous and smoothly tapered in the posterior region, close to the contact with supraoccipital (Figures 4F, 5F).” (Abegg et al. 2022) |
Comment | Synonymy that of Hoge 1958 and PETERS & OREJAS-MIRANDA 1970. BOULENGER (1890) thought that Xenodon punctatus is a member of Pseudoxyrhopus and its origin is from Madagascar. Note that Amaral described Sordellina pauloensis as a new species in two independent papers, published in 1923 and 1926. Distribution: One record from Mato Grosso do Sul is doubtful (Miranda & Fernandes 2012). See map in Nogueira et al. 2019. Type species: Sordellina brandon-jonesii Procter 1923 = Xenodon punctatus PETERS 1880: 221 is the type species of the genus Sordellina PROCTER 1923. |
Etymology | Probably named after the white spots on many scales, at leas tin some specimens. |
