BC1087DEFFAB1E08FF69F58B9ADDF822.taxon	diagnosis	Diagnosis. Calamaria mizoramensis sp. nov. can be distinguished from all other species congeners by the combination of the following morphological characters: 8 – 11 enlarged maxillary teeth; rostral higher than wide; prefrontal shorter than frontal and contacting the first two supralabials; mental not in contact with anterior chin shields; dorsal scales in 13 – 13 – 13 rows, smooth throughout; a single preocular and postocular; four supralabials, with the 2 nd and 3 rd ones contacting the eye; five infralabials; six scales surrounding the paraparietal; 147 – 175 ventrals; 13 – 27 paired subcaudals; a relatively short tail (10.3 – 13.1 % in males, 4.7 – 6.5 % of total length), thick and nearly cylindrical, terminating in an obtuse tip; dark brown to blackish-brown, with three to six longitudinal rows of slightly paler or dark-edged scales forming indistinct stripes of variable clarity along the body and a faint pale nuchal ring; a yellow ventral surface with dark outer corners on the ventral scales; and a broad, distinct median black stripe on the ventral surface of the tail.	en	Lalremsanga, Hmar Tlawmte, Malsawmdawngliana, Fanai, Bal, Amit Kumar, Vabeiryureilai, Mathipi, Hruaia, Vanlal, Korolev, Alexey M., Vogel, Gernot, Poyarkov, Nikolay A., Nguyen, Tan Van (2026): A new species of the genus Calamaria H.

BC1087DEFFAB1E08FF69F58B9ADDF822.taxon	description	Description of the holotype (Figs. 2 – 3). Specimen MZMU 3744 is in excellent condition. Body slender, cylindrical (SVL 220 mm); tail short, thinner than body, uniformly cylindrical in its anterior portion and abruptly tapering toward the tip; tail tip obtusely pointed (TaL 31 mm, TaL / TL 12.4 %). Head small and elliptical in dorsal view (HL 6.6 mm, HW 4.4 mm); eye small and round (ED 1.2 mm), smaller than the eye-nostril distance (EN 1.7 mm). Head scalation (Fig. 3). Rostral broader than high (RT-w 1.4 mm, RT-h 1.6 mm), its dorsal portion visible from above approximately half the length of the prefrontal suture (Fig. 3 B). Prefrontal shorter than the frontal, not entering the orbit, and in contact with the 1 st and 2 nd supralabials (Fig. 3 A). Frontal hexagonal, longer than wide (FT-l 2.7 mm, FT-w 2.1 mm) (Fig. 3 B). Paraparietal surrounded by six scales (Fig. 3 A). One preocular on each side, higher than wide, slightly taller than the postocular but shorter than the eye diameter (Fig. 3 A). One postocular on each side, also higher than wide. Nasals divided, small, barely surrounding the nostrils, bordered by the rostral, prefrontal, and 1 st supralabial (Fig. 3 A). Four supralabials on each side; the 2 nd and 3 rd enter the orbit; the 4 th is the largest (relative size: 4> 2> 1> 3). Five infralabials on each side; the first three pairs contact the anterior chin shields; the 1 st pair meet at the midline; the 4 th is the largest. Anterior chin shields are longer than wide, pentagonal, and meet at the midline (Fig. 3 C). Posterior chin shields are shorter, in contact anteriorly and separated posteriorly by the first gulars. Mental triangular, not in contact with the anteriorly, chin shields (Fig. 3 C). Body scalation. Dorsal scale rows 13 – 13 – 13 throughout, all smooth. Dorsal rows reduce as follows: to 11 rows above the second subcaudal, to six rows above the 7 th and 9 th subcaudals, to five rows above the 28 th subcaudal, and to four rows above the last six subcaudals. Ventrals 149, with two preventrals; subcaudals 25, all paired, the first pair not in contact. Cloacal plate undivided. Dentition. Maxillary teeth modified (enlarged), 9 on each side (9 / 9). Hemipenis. Hemipenis short, bilobed, and weakly calyculate (Fig. 2 H – I); lobes moderately expanded, rounded distally. Sulcate view (Fig. 2 I) with shallow sulcus spermaticus running medially along the truncus and bifurcating towards the apex of each lobe; calyces poorly developed, restricted to apical portions of lobes. Asulcate surface (Fig. 2 H) smooth, lacking prominent ornamentation; proximal portion of organ narrow and unadorned. Colouration (Fig. 2). In life, the dorsal surface of the head, body, and tail is blackish-brown, with six narrow and slightly distinct longitudinal stripes running along the body. These stripes are formed by six longitudinal rows of slightly paler or dark-edged scales, most prominent on the dorsolateral region; a bright vertebral stripe visible in Fig. 2 A is a photographic artefact .. The nuchal ring is narrow and pale yellow, extending from the posterior margin of the parietals to approximately the level of the fourth ventral scale; it is distinct but incomplete dorsally. The eye is black. The supralabials are dark brown with lighter mottling, while the ventral surface of the head is yellow with scattered dark speckles, particularly on the infralabials and anterior chin shields. The ventral surface of the body is uniformly yellow, with dark pigmentation confined to the outer margins of the ventral scales, forming a narrow lateral line. The underside of the tail is yellow with a prominent median dark stripe extending from the second subcaudal to the tip. In preservative, the overall colouration is slightly faded, but the dorsal stripes and nuchal ring remain clearly visible. Variation (Figs. 4 – 5). Variation in measurements and scalation of the type series is summarised in Table 3. The largest male is the holotype (MZMU 3744) with a total length of 251 mm, while the largest known specimen overall is a female paratype (MZMU 869), reaching a TL of 259 mm. Sexual dimorphism is evident in several characters. Females possess significantly more ventral scales (VEN 166 – 175) than males (VEN 147 – 155), but fewer subcaudal scales (SC 13 – 15 in females vs. 22 – 27 in males). Tail proportions also differ markedly between sexes: adult males have relatively longer tails (TaL / TL ratio 10.3 – 13.1 %), whereas adult females have shorter tails (TaL / TL ratio 4.7 – 6.5 %). Colour variation. The dorsal surface of the body and tail is dark brown to blackish-brown, with six narrow longitudinal stripes formed by lighter and darker scale margins; these stripes are especially distinct on the dorsolateral rows. Nuchal ring pale yellow to cream, variably developed among individuals ranging from complete and prominent (e. g., Figs. 5 C – D) to incomplete or faint (e. g., Figs. 5 E – F). Head uniformly dark dorsally, with subtle mottling on the supralabials; eye large and black. Ventral surface bright yellow to cream, immaculate or with faint dark margins on outermost ventral scales, forming a narrow line along each side in some specimens. The tail underside has a pronounced dark median stripe extending from just behind the cloaca to the tip, contrasting with the yellow background. Variation in dorsal hue among individuals ranges from reddish-brown (Fig. 5 B) to glossy bluish-black (Fig. 5 E), possibly influenced by lighting or preservation state. The overall colouration provides effective camouflage in leaf litter habitats.	en	Lalremsanga, Hmar Tlawmte, Malsawmdawngliana, Fanai, Bal, Amit Kumar, Vabeiryureilai, Mathipi, Hruaia, Vanlal, Korolev, Alexey M., Vogel, Gernot, Poyarkov, Nikolay A., Nguyen, Tan Van (2026): A new species of the genus Calamaria H.

BC1087DEFFAB1E08FF69F58B9ADDF822.taxon	etymology	Etymology.

BC1087DEFFAB1E08FF69F58B9ADDF822.taxon	biology_ecology	Natural history, distribution, and conservation status (Figs. 8 – 9). Calamaria mizoramensis sp. nov. is currently known with certainty only from Mizoram State, India, with confirmed records from four districts: Aizawl, Mamit, Saitual, and Kolasib. Its occurrence in other parts of India remains unverified; however, it is likely to be present in adjacent states such as Manipur, Nagaland, and Assam. A possible extension into the Chittagong Division of Bangladesh cannot be ruled out, but this requires further confirmation (Poyarkov et al. 2023; T. V. Nguyen, pers. obs.). The species appears to be a nocturnal, semi-fossorial snake inhabiting humid, forested environments (Fig. 8) in hilly regions of Mizoram State and likely neighbouring areas, including the Lushai, Naga, and Chin Hills. It is known to occur at elevations ranging from 670 to 1,295 m asl. Although ecological data are limited, Calamaria mizoramensis sp. nov. has been recorded from multiple localities (Fig. 9), and no major anthropogenic threats have been identified across its known range. Based on currently available information and following the IUCN Red List Categories and Criteria, we tentatively assess the species as Least Concern (LC), as it is known from several localities across Mizoram state with no major anthropogenic threats identified (IUCN 2025).	en	Lalremsanga, Hmar Tlawmte, Malsawmdawngliana, Fanai, Bal, Amit Kumar, Vabeiryureilai, Mathipi, Hruaia, Vanlal, Korolev, Alexey M., Vogel, Gernot, Poyarkov, Nikolay A., Nguyen, Tan Van (2026): A new species of the genus Calamaria H.
