Researchers have described a brand new species of snake from the genus Calamaria. The Calamaria genus is comprised of 66 acknowledged species of dwarf, burrowing snakes. The brand new species, Calamaria mizoramensis sp. nov (proposed “Mizoram Reed Snake”) was found in Mizoram State, India. Mizoram sits at an elevation of 670 to 1,295 meters.
The burrowing snake species was present in montane evergreen forests within the state and provides to the variety of herpetological findings within the space that contains an Indo-Burma biodiversity hotspot. The researchers say the herpetofauna in Mizoram state at the moment contains 169 species, together with 117 reptiles and 52 amphibians.

Calamaria mizoramensis Description
Calamaria mizoramensis is genetically various from its congeners from a distance of 15.3 p.c, the researchers say. It’s totally different from its congeners by its “8-11 enlarged maxillary enamel; rostral greater than broad; prefrontal shorter than frontal and contacting the primary two supralabials; psychological not involved with anterior chin shields; dorsal scales in 13-13-13 rows, clean all through; a single preocular and postocular; 4 supralabials, with the 2nd and three rd ones contacting the attention; 5 infralabials; six scales surrounding the paraparietal; 147-175 ventrals; 13-27 paired subcaudals; a comparatively brief tail (10.3-13.1% in males, 4.7-6.5% of complete size), thick and practically cylindrical, terminating in an obtuse tip; darkish brown to blackish-brown, with three to 6 longitudinal rows of barely paler or dark-edged scales forming vague stripes of variable readability alongside the physique and a faint pale nuchal ring; a yellow ventral floor with darkish outer corners on the ventral scales; and a broad, distinct median black stripe on the ventral floor of the tail,” the researchers wrote of their paper and as described within the summary detailing the brand new species.
The researchers performed DNA evaluation to substantiate Calamaria mizoramensis as a brand new species. The snake is blackish-brown in coloration on its dorsal aspect and yellow on its ventral aspect with a darker stripe from the second subcadault to the tip of the tail. It options six longitudinally stripes operating alongside its physique. The male holotype had a complete size of 251mm whereas the feminine had a complete size of 259 mm. The researchers say the coloration of the snake supplies nice camouflage within the leaf litter habitats the place the snake can typically be discovered.
The snake is within the household Colubridae. An summary of the paper describing the brand new species, “A brand new species of the genus Calamaria H. Boie in F. Boie, 1827 (Squamata: Calamariidae) from Mizoram State, India” might be learn on the ResearchGate web site.
