Yunnanilus jinxiensis is a new member of the Yunnanilus pleurotaenis group. It can be distinguished from all other congeners in this group by the following characters: body entirely covered by scales, except between pectoral fins and pelvic fins; lateral line present, with 15–20 pores; dorsal fin with 8 branched rays; pectoral fin with 13–14 branched rays; the air bladder has two chambers, the anterior ones into bony capsules and a large free posterior chamber, filling body cavity; caudal fin slightly emarginated; body depth 3.9–4.6 times the standard length (SL); head length 4.1–4.4 times SL; caudal peduncle depth 7.5–9.0 times SL; eye diameter 5.5–6.7 times the head length (HL); interorbital width 2.2–2.4 times HL.
