Description
This dataset contains the digitized treatments in Plazi based on the original journal article Chandramouli, S. R., Gokulakrishnan, G., Sivaperuman, C. (2020): Status and distribution of the little-known and elusive Nicobarese worm lizard Dibamus nicobaricum (Fitzinger in Steindachner, 1867) (Squamata: Dibamidae). Bonn zoological Bulletin 69 (1): 131-140, DOI: 10.20363/BZB-2020.69.1.131, URL: dx.doi.org/10.20363/bzb-2020.69.1.131 Abstract.
Field surveys were carried out to record the elusive and little-known fossorial Nicobarese worm lizard Dibamus nicobaricum (Fitzinger in Steindachner, 1867) on seven of the 23 islands of the Nicobar archipelago. It was recorded from three new localities, two in Great Nicobar and the other from Teressa Island, extending the northern and southern boundaries of its distribution significantly. One of the individuals, a subadult male recorded during this study happens to be the smallest one ever recorded, measuring just 70 mm SVL.

A predictive distribution model was developed based on the geo-coordinates of its occurrence with a reliable prediction of 25–100% probability on islands of the central and southern group of the Nicobar archipelago, diminishing to 12–25% on Car Nicobar, situated to the north. The Area Under the Curve (AUC) of the model was 0.907, indicating a reliable prediction. Status of D. nicobaricum was assessed for the first time as per the IUCN guidelines which reveal that it has to be considered as an endangered species based on its narrow distribution range.
