Vidthayanon and Jaruthanin 2002
Holotype: NIFI 3131 75.21mm SL (male). Paratypes: NIFI 3132 (3 specimens) 37.45 – 49.56mm SL.
Known only from the type locality: Phu Tham Nam, Ban Don Yom, Khammouan karst, Laos PDR (18o45’-18o30’N, 104o45’-105o00’E). Waltham and Middleton (2000) provide details of the Khammouan karst.
The type specimens, and some others, were collected in deep and shallow waters 600m from the cave entrance. A second species has also been observed in this cave, possibly Troglocyclocheilus khammouanensis. If confirmed this will be another case where two troglomorphic fishes co-exist in one cave.
No details available.
TLO [VU D2:3.1:2011]
(Vidthayanon, C. 2011. Schistura kaysonei. The IUCN Red List of Threatened Species 2011: http://dx.doi.org/10.2305/IUCN.UK.2011-1.RLTS.T180902A7654836.en. Downloaded on 14 July 2017). This fish is only known from subterranean streams in caves in Kham Muan Province, Lao PDR. Given the single location, the nature of the hydrological system, and the likely limited extent of occurrence, the species is assessed as Vulnerable (D2). Current and potential threats are tourism development and degradation of the surrounding watershed and water quality.
