Distribution: BOETTGER 1892 reported this species from Aden (Yemen) which may be a misidentification.
Synonymy: ladacensis has been considered a color pattern variation of rhodorachis ever since J. Anderson (1895) recognized that this species had already been described by Jan in 1865 (fide RASTEGAR-POUYANI et al. 2008). Listed as synonym of Platyceps rhodorhachis by WALLACH et al. 2014: 566.
Anderson (1871) described this taxon as “pale olive brown, marked on the anterior half of the body by broad brown dorsal bands only a little darker than the general colour of the snake, distinct near the anterior part of the body, but obscure behind.” The ventrals were described as “pale yellow,” and dorsal scales had two apical pores. The type specimen had 102 pairs of subcaudal scales.
