Revision of the cyprinid genus Discogobio Lin, 1931 (Pisces: Teleostei) from the upper Red River basin in Wenshan Prefecture, Yunnan, China, with descriptions of three new species

Full Paper


The species of the genus Discogobio (Teleostei: Cyprinidae) inhabiting the Wenshan prefecture (branches of upper Red River) of Yunnan Province, China are reviewed. The authors recognize four species from the prefecture, Discogobio antethoracalis n. sp., Discogobio propeanalis n. sp., Discogobio poneventralis n. sp., and D. yunnanensis. D. antethoracalis and D. propeanalis had previously been identified as Discogobio brachyphysallidos. D. antethoracalis can be distinguished from D. brachyphysallidos by the following characters: snout rounded, not projected (versus slightly pointed, projected); head length 17.5–20.6% of SL (vs. 20.8–22.8); prepectoral length 16.3–18.3% of SL (vs. 19.1–22.0); interorbital width 52.5–60.9% of head length (vs. 44.7–50.0); anus to anal-fin origin distance 25% posterior end of pelvic-fin base to anal-fin origin distance (versus less than 25). D. propeanalis can be distinguished from D. brachyphysallidos by the following combination of characters: interorbital width greater than half of head length (versus less than half); pelvic-fin extending beyond anal-fin origin (versus not reaching anal-fin origin); anus closer to anal-fin origin, anus to anal-fin origin distance less than 25% posterior end of pelvic-fin base to anal-fin origin distance (versus more than 25%). D. poneventralis, with a small oral sucking disc (its posterior edge not reaching vertical of anterior margin of eye) is similar to Discogobio longibarbatus and D. macrophysallidos, but distinct from them in the following characters: rostral barbels equal to eye diameter (versus twice as long as eye diameter in D. longibarbatus); maxillary barbels not reaching posterior margin of oral sucking disc (versus beyond in D. longibarbatus); mid-ventral region anterior to pelvic-fin insertion scaleless (versus scaled in D. macrophysallidos); prepelvic length 57.1–58.1% of SL (vs. 52.4–55.6 in D. macrophysallidos); pectoral-pelvic length 40.8–41% of SL (vs. 32.6–35.9 in D. macrophysallidos); head length 17.5–18.4% of SL (vs. 19.8–21.8 in D. macrophysallidos); and snout length 44.9–47.2% of HL (vs. 48.9–55.4 in D. macrophysallidos).
