In the present study, we report the discovery of the poorly known striped ichthyophiid caecilian Ichthyophis longicephalus from three new localities, each in three southern Indian states; Karnataka, Kerala and Tamil Nadu. Present records and available information on this species enable us to revise its IUCN Red List conservation status from Data Deficient (DD) to Least Concern (LC).

Schneider’s Toad, Duttaphrynus scaber (Schneider, 1799) is known to be distributed over the coastal peninsular, northern parts of central India and northeastern states of India. However, despite the availability of multiple published reports, there are few verified records of its occurrence from central India. Herein, we present two records of D. scaber, one from the Vidarbha region of Maharashtra State, central India with morphometric data, another from northern Western Ghats, from the Goa region, with morphometric, as well as molecular, data. The site selection for dormancy, sympatric species, and microhabitat preferences during the breeding season of Duttaphrynus scaber is discussed.

Based on a collection of Kurixalus specimens collected from different localities in Mizoram State, we report the occurrence of Kurixalus yangi from the State. Species identification was confirmed based on morphology and molecular data (mitochondrial 16S rRNA marker gene sequence). In addition, we confirm the previous record of Kurixalus naso from the same region to be erroneous as it is in fact K. yangi. Herein, we reassess the systematic status of this montane population of Kurixalus from Northeast India and provide evidence for its distinction from Kurixalus naso sensu stricto, thereby reporting K. yangi as an addition to the amphibian fauna of Mizoram. This record represents the southernmost distribution of the species.

We provide an account on the distribution, morphology and biology of the Indian trinket snake, Coelognathus helena (Daudin, 1803) from Gujarat, India, and report the first record of the subspecies, Coelognathus helena nigriangularis Mohapatra, Schulz, Helfenberger, Hofmann, Dutta from the Gujarat state based on reptile surveys throughout the state. We show that our understanding regarding the morphology of this species is not fully known as our series of specimens shows a high range of 204–245 ventral scales in C. h. helena and 219–279 ventral scales, 78–98 subcaudal scales in C. h. monticollaris.
