Abstract: Glyptothorax rhadinus can be distinguished from Mekong congeners by its very slender TAA (width 1.9–2.2 times in its length vs. 1.1–1.9) and a combination of characters in colour pattern, thoracic adhesive apparatus (TAA) morphology, nuchal plate shape, and morphometry. Habitat: The Stung Prek Thnot is a small river about 30–100 m wide, with a substrate of sand mixed with silt and moderate to slow flow. At the time the ZRC and CMK paratypes were collected, the river had dried up into a small trickle in the main channel discharging into a series of pools of varying sizes no more than 70 cm deep (J. Bohlen, pers. comm.), (Ng & Kottelat, 2025). Etymology: The specific name rhadinus: The specific epithet is the Latinised from of the Greek paôrvôç, meaning slender. The name refers to the very slender TAA of this species. Remarks: previously confused with G. fuscus and G. lampris, and comparisons with these two species are provided (Ng & Kottelat, 2025). |
