| Diagnose |
Exostoma tenuicaudata is distinct from its congeners by having an elliptical adhesive pad medially between the anterior margin of the snout and the mid-upper lip margins, further connected posteriorly by a fleshy pad up to the mid-upper lip, and a more slender caudal peduncle (3.6-4.7% SL or 13.8-17.2% CPL). It further differs from its congeners by the following combination of characters: snout length 60.2- 61.8% HL; interorbital width 24.4-26.4% HL; interdorsal distance13.0-13.5% SL; caudal peduncle depth 3.6-4.7% SL and 13.8-17.2% CPL; CPL 26.3-28.0% SL; prepectoral length 16.8-18.9% SL; predorsal length 34.9-39.0% SL; prepelvic length 42.4-44.6% SL; preanal length 68.1-70.1% SL; length of adipose-fin base 30.8-32.9% SL; length of dorsal-fin base 7.9-10.8% SL; length of anal-fin base 3.9-5.3% SL; caudal-fin length 14.3-19.4% SL, maxillary barbel 63.5-72.1% HL, nasal barbel 19.9-26.3% HL; eye diameter 10.0-16.0% HL; pectoral-fin rays 11-12; and adipose-fin not confluent with dorsal-fin base (Ref. 105469). |
