Type locality: Devarayana Durga (13.371°N, 77.210°E; 1,060 m asl) in Tumkur district, Karnataka, India.  
Reproduction 
TypesHolotype: BNHS 3596, coll. K.G. Punith and Ashok
Kumar Mallik in June 2012.
Paratype: ZSI 13271 from South Arcot district, Tamil Nadu, India; Mus. Coll. Jaffa (also see Sclater 1891). 
DiagnosisDiagnosis: A species of Lycodon inhabiting the Deccan plateau of India, characterized by: small size (total length < 470 mm); scales smooth, in 16–17:17:15 rows, without apical pits; usually 9 supralabials (10, in one case); ventrals 181–201 (n = 9) angulate laterally; anal plate undivided; subcaudals 68–78 (84; n = 8), paired; loreal in contact with internasal, separate from eye; nasal not in contact with prefrontal; anterior pair of genials subequal to posterior pair; supraocular usually contacting prefrontal; preocular usually not contacting frontal (preocular separating frontal, prefrontal, and supraocular in one case); dorsum brown in adults and black in juveniles, with white cross bars. Due to the slender body and smaller head, the new species superficially resembles the genus Dryocalamus, its higher midbody scale rows (17) and lower ventral counts (181–201; avg. 190; n = 9) [vs. rows 13–15; ventrals 200+ in Dryocalamus, see Smith 1943] clearly indicate this species belongs to the genus Lycodon, even if Dryocalamus is regarded as a valid genus (Ganesh et al. 2020).
