(Figs. 2 D, 8 A, B) Four specimens morphologically consistent with Maculabatis gerrardi were examined. These came from landing sites in Pukulam (SL- 9) and Puttalam (SL- 15) in the North Western Province and fish markets in Munai (SL- 40) and Kotaddi (SL- 58) at Point Pedro in the Northern Province. Two (SL- 9 and SL- 58) were immatures and two (SL- 40 and SL- 15) were mature. The latter mature specimen had already been processed for sale and consisted solely of the right side of the disc. Both immature specimens were morphologically consistent with the immature specimen from Malaysian Borneo used as the reference specimen for M. gerrardi (BO- 163; JQ 519087) in our analysis; both specimens possessed a few white spots on the dorsal surface of the base of the tail grading into alternating black and white bands throughout the length of the tail. Both of the mature specimens exhibited sparse, small white spots restricted to the posterior margin of the disc and pelvic fins, typical of adults of M. gerrardi. All four specimens from Sri Lanka grouped in a tight cluster with the reference specimen of M. gerrardi. They differed from one another by 0 – 3 bp and from the reference specimen by 5 – 6 bp. This species has previously been referred to as Himantura gerrardi (Gray) (e. g., De Bruin et al. 1995; Morón et al. 1998; De Silva 2006). That name has been updated here to reflect current nomenclature (Last et al. 2016).
