Two new species of Glyptothorax (Teleostei: Sisoridae) from central Vietnam.Abstract
Two new species of Glyptothorax are described from the rivers draining the Annam Cordilleras in central Vietnam. Glyptothorax filicatus n. sp. is distinguished from congeners in Indochina in having a diverging pattern of striae running along the edges of the central depression in the thoracic adhesive apparatus, and a combination of the following characters: dorsal spine length 13.7–15.1% SL, pectoral fin length 21.5–21.9% SL, length of adipose-fin base 13.3–15.0% SL, depth of caudal peduncle 8.4–8.8% SL, body depth at anus 15.1–16.0% SL, snout length 48.0–52.9% HL, eye diameter 8.9–9.9% HL, anterior nuchal plate strongly demarcated in beige and caudal peduncle with a pale vertical band. Glyptothorax strabonis n. sp. is distinguished from congeners in Indochina in having a very small eye (6.2–6.5% HL), and a combination of the following characters: length of caudal peduncle 20.5–21.2% SL, depth of caudal peduncle 7.5–9.2% SL, body depth at anus 13.7–20.9% SL, head width 17.9–18.8% SL, presence of 14–16 serrae on posterior margin of pectoral spine, and coloration consisting of a dark-brown body with indistinct pale mid-lateral and mid-dorsal stripes.
