背的软条 (总数) : 8; 臀鳍软条: 17 - 19; 脊椎骨: 46 - 49. Olyra saginata can be diagnosed from all species of the genus Olyra by the possession of the following unique combination of characters: interorbital distance 27.9-35.9% HL; 54-66 pored lateral line scales; body depth at anus 10.5-12.0% SL; length of adipose-fin base 17.3-22.4% SL; adipose fin separate from upper principal caudal-fin rays; post-adipose distance 11.8-14.3% SL; caudal peduncle length 14.8-17.7% SL; and caudal peduncle depth 7.8-8.9% SL (Ref. 96386).
Body shape (shape guide): elongated.
Found in a shallow stream with moderate to strong current and substrate composed of sand, pebble and rocks. Occurs in association with the following fish species: Badis spp. (Badidae), Rasbora rasbora (Cyprinidae), Garra spp, (Cyprinidae), Glyptothorax chimtuipuiensis (Sisoridae), G. caudimaculatus (Sisoridae) and Pseudolaguvia nubila (Sisoridae) (Ref. 96386).
