| Diagnosis | Diagnosis: Adult specimens of Stenocercus diploauris can be easily distinguished from all known species of Stenocercus by having a C-shaped nuchal mite pocket around the oblique fold, posteriorly limited by the antehumeral fold (Fig. 4). However, among the 69 currently known species of Stenocercus, S. diploauris resembles S. formosus Tschudi, 1845, and S. ochoai Fritts, 1972, by the combination of the following characters: (1) imbricate scales on the posterior surface of thighs, (2) well developed postfemoral mite pocket, (3) antehumeral and oblique neck folds, and (4) absence of posthumeral mite pocket. The new species can be distinguished from S. ochoai and S. formosus by having dorsal and lateral nuchals similar in size and the presence of longitudinal neck fold, in the former species lateral nuchals are smaller than dorsal nuchals and the longitudinal neck fold is absent. Furthermore, S. diploauris differs from S. formosus (character state of latter in parenthesis) by having three whorls per autotomic segment (four), smooth dorsal head scales (keeled), and fewer scales, 50–61, around midbody (74–82) (Venegas et al. 2020). |
| Comment | |
| Etymology | The specific epithet “diploauris” is a noun (in apposition) in the nominative singular and derives from the Greek word diploos (= double) and the Latin word auris (= ear). It refers to the depression on both sides of the neck of the new species, appearing like a second tympanic opening. |
