Types

Holotype: IHB 2016092883 74.6 mm SL. Paratypes: IEBR 2884–5 50.7 and 54.4 mm SL, IHB 2016092886–8 3 specimens 61.8–69.0 mm.
SL

Distribution

Known only from the type locality: Hang Va Cave, Phong Nha-Ke Bang National Park (Son River basin) at Tan Trach Commune, Bo Trach District, Quang Binh Province, Central Vietnam. (17o29’29’’N, 106o17’06’’E).

Habitat

Collected from a small vadose pool with a muddy substrate. Up to 30 individuals observed. The troglobitic shrimp Macrobrachium phongnhaense (Decapoda: Palaemonidae) is found in the same cave and is probably part of the food supply for the fishes (Do and Nguyen 2014).

Systematics

Speolabeo is currently placed in the tribe Labeonini in the subfamilly Labeoninae (Tan and Armbruster 2018) but it is by no means certain that this will remain the case. A morphological analysis by Tao et al. (2018) suggests that the, currently, congeneric Speolabeo musaei may be more closely related to species in the genera Bangana and Altigena (also within the Labeonini) than it is tlo S. hokhanhi. There is a sugestion that the tribal placement may be wrong  and that molecular evidence would be valuable in this regard.
