Diagnosis | Diagnosis: An old, isolated clade of relatively smallgrowing ratsnakes (total length 800 – 1000 mm) within the collective genus Elaphe auct. which branched off after the Rhadinophis and the Euprepiophis-Oreocryptophis clades (Burbrink and Lawson, 2007). From the latter two genera, it is distinguished by (1) a weakly (vs. markedly) concave frontal shield; (2) a consistently lacking loreal shield (present in Oreocryptophis and Euprepiophis, lacking only exceptionally in some E. mandarinus); (3) a dorsal head pattern of an anteriorly open Vor Y-shaped marking (vs. a posteriorly open V-shaped marking in Euprepiophis, or a longitudinal midline streak in Oreocryptophis); and (4) its hemipenis with a slightly expanded, calyculate and indistinctly asymmetrical apex (vs. subcylindrical, spiny and bilobed in Oreocryptophis, and distinctly expanded, spiny and asymmetrically bipartite in Euprepiophis mandarinus and perlaceus, subcylindrical in E. conspicillatus).

Comment | Synonymy: WERNER (1929) established Zamenis brachyura Günther, 1866 (currently Coronella brachyura) as the type species of Wallophis, and allocated also “Coronella (Wallophis) pulchra” to his new genus. Wallophis was revived in a non-peer reviewed journal (Litteratura Serpentium), without adequate justification (by Ken Welch) and is thus not recognized here. Coluber leonardi WALL 1921 is a synonym of Coronella bella STANLEY 1917 (= Elaphe bella) fide SCHULZ (2000). See SCHULZ et al. 2011 for a more extensive chresonymy. Maculophis BURBRINK & LAWSON 2007 is a nomen nudum fide BÖHME & DE PURY 2011. Type species: Coronella bella STANLEY 1917 is the type species of the genus Archelaphe SCHULZ, BÖHME & TILLACK 2011. Distribution: Not listed for India by Whitaker & Captain 2007. Schulz 2000 lists only China, Myanmar, and Vietnam as countries. Wallach et al. 2014 also list Laos and Nagaland in India. |
Etymology | Derived from the Greek word archaios (= old), archaic, in reference to the basal position of the Archelaphe clade in the phylogenetic tree of Elaphe auct. |
