Etymology: Schistura: Greek, schizein = to divide + Greek, oura = tail; an allusion to forked caudal fins (Ref. 45335); scripta: Name from Latin 'scripta' meaning ‘written words’, referring to the pattern of bars on the side of the body of this species resembling alphabetical characters.

This species is distinguished from its congeners from Sri Lankan and peninsular India by the following characters: lateral line incomplete with 53-76 pores, ending beneath the dorsal-fin base or slightly beyond; post-dorsal bars 7-13; D 7½ branched rays; no axillary pelvic lobe; absence of a suborbital flap (Ref. 127984).

This species is known only from its type locality, a stream about 3-4 m wide, flowing through the palm-oil plantations of Nakiyadeniya Estate in an unprotected area of the Gin River basin, elevation ca. 80 m above sea level and where the substrate consists of small boulders and pebbles. It prefers the faster-flowing regions of the stream and was observed with Garra ceylonensis, Rasbora dandia, Belontia signata. It appears to be locally abundant when sampled during a relatively dry period in December 2017 and about 100 adults, including several gravid females, were observed in a stretch of approximately 50 m along the length of the stream. Schistura notostigma was recorded in similar habitats sampled in Udugama about 8 km from the type locality of S. scripta and as presently understood, these two species do not co-occur (Ref. 127984).
