Application of taxonomy exclusively based on external morphology, molecular phylogeny and noninvasive anatomical investigation using micro CT scanning together is effective in resolving systematic problems, such as cryptic species. The external morphology, skull osteology and molecular phylogeny of Baran’s black-headed dwarf snake, Rhynchocalamus barani, and a subspecies of the Palestine kukri snake, Rhynchocalamus melanocephalus, were examined. Considerable osteological and molecular differences indicate that the genus Rhynchocalamus is paraphyletic. As a result, Baran’s black-headed dwarf snake should be referred to a monotypic genus, Muhtarophis gen. nov. Based on morphology and molecular data, R. satunini, previously known as a subspecies of R. melanocephalus, should be assigned the rank of species.

Derivatio nominis. The new genus is named after Prof. Dr. Muhtar Baþoðlu, the first Turkish herpetologist, together with ophis, i.e., snake; the gender is masculine.
Etymology. The new species is in dedication to Prof. Dr. İbrahim BARAN of the University of Dokuz Eylül, İzmir, to acknowledge his prolific and uninterrupted contribution to the herpetology of the Turkey.
Distribution. Muhtarophis gen. nov. is endemic to Turkey. It is only recorded in Hatay Province, Turkey.
