Vidthayanon and Kottelat 2003
Holotype: NIFI 3148 217mm SL. Paratypes: NIFI 3149 (13 specimens, 37.1-103.9mm SL), NIFI 3076 126.7mm SL, NIFI 3143 9 (4 specimens, 40.1-120.0mm SL), CMK 16876 77.5mm SL.
Known only from the type locality: Tham Phra Wang Daeng cave, Thung Salaeng Luang National Park, Phitsanulok Province, Thailand (16o40’41”N, 100o41’24”E). This species coexists with Schistura spiesi (Balitoridae).
Lives throughout the length of the cave, often found in large numbers in deep pools. Food probably consists of plant matter and detritus, together with bat guano.
Despite a thorough review Vidthayanon and Kottelat (2003) were unable to provide details of the of possible relationships of this species.
TLO [VU D2:3.1:2011]
(Vidthayanon, C. 2011. Neolissochilus subterraneus. The IUCN Red List of Threatened Species 2011: http://dx.doi.org/10.2305/IUCN.UK.2011-1.RLTS.T180812A7652344.en. Downloaded on 04 July 2017).
This fish is known only from subterranean streams in Tham Phra Wangdaeng cave, Pitsanulok Province in Thailand, within the Chao Phraya basin. It is assessed as Vulnerable (D2) as it is only known from a single location and it is potentially threatened by tourism developments at the site, as well as by upstream agricultural pollution. Further research into the species' current distribution and population trends is needed.
However, Smart (in Vidthayanon and Kottelat, 2003) suggests that the population may be declining, and gives several reasons for this including drought and anthropogenic influences. Taking this into account it seems likely that CR B1ab(i, ii, iii, v) + 2ab(i, ii, iii, v) is a sensible current assessment. As in the description of the hypogean Cottus bairdi-cognatus complex, it is encouraging to see discussions of conservation status at the outset of the knowledge of a species.
As above only.
