Sudasinghe, Hiranya, Kottelat, Maurice & Pethiyagoda, Rohan, 2025, The collection of Sri Lankan freshwater fishes reported on by Pieter Bleeker (1863) (Osteichthyes: Cyprinidae, Danionidae, Nemacheilidae), Zootaxa 5647 (5), pp. 461-468 : 465

Schistura notostigma

( Figure 2a–d )

Material. Syntypes, RMNH.PISC.2709.A , 54.0 mm SL; RMNH.PISC.2709.B , 54.8 mm SL; and RMNH.PISC.2709 . C, 43.3 mm SL .

For metric and meristic data, see Table 1 .

Differentiation. The syntypes of Schistura notostigma are consistent with the conception of this species by Sudasinghe (2017, 2018) from the south-western river basins of Sri Lanka, from the Kelani to the Nilwala. It differs from S. madhavai Sudasinghe, 2017 by possessing 6–7 (vs 8–9) postdorsal bars and having the width of interspaces and bars subequal (vs. interspaces much narrower than bars); and from S. scripta Sudasinghe, 2018 , by possessing 28–30 (vs 53–76) lateral line pores, and 6–11 (vs 11–20) total bars on the side of the body.
