DistributionBangladesh, Iran, India (Gujarat, Rajasthan, Kerala, Madhya Pradesh, Odisha etc.), Nepal, Pakistan, Sri Lanka, possibly areas of Indochina

Type locality: Mainland India;  
Reproductionoviparous. Exhibits temperature‐dependent sex determination (TSD) fide Cornejo-Páramo et al. 2020 (and references therein). 
TypesHolotype: unlocated fide King & Burke 1989.
Holotype: BMNH 1947.3.6.36-37 ( [trigonops] 
CommentSynonymy: mostly after WERMUTH & MERTENS 1977.

King & Burke 1989 noted that the type locality was “restricted to Ganges by Lesson (1831: 305, not Lesson 1831: 121 which is a different publication)”. However, this is incorrect. Lesson 1831: 305 stated that “ "ce crocodile ne va jamais dans le Gange", which means that this species never enters the Ganges, so this is not a restriction of the type locality. (Note: Lesson 1831 is sometimes cited as 1834 because this work was published in sections until 1834).

The common name, “mugger” is a corruption of the Hindi word “magar”, meaning “monster of the waters”. 
EtymologyNamed after Latin palustris = marshy, swampy.
