Diagnosis. Tympanopleura longipinna can distinguished from T. atronasus and T. cryptica on the basis of its much longer anal fin (32-42 anal-fin rays vs. 23- 30). Tympanopleura longipinna is further distinct from T. atronasus in having more pectoral-fin rays (10-13 vs. 7-9), more gill rakers on the first arch (19-25 vs. 14-18), fewer preanal vertebrae (13-15 vs. 16-19), more total vertebrae (40-43, mode 43 vs. 39-43, mode 41), fewer pleural ribs (4-5 vs. 7-8), greater distance from pelvic- to adipose-fin origin (37.6-45.1% SL vs. 31.2-38.1%), longer anal-fin base (33.9-39.9% SL vs. 22.1-27.6% SL), and a generally lighter overall pigmentation pattern on the head, dorsum, and sides of the body, lacking the characteristic dark patches of melanophores concentrated on the flanks above the anal-fin base, the chin, and streaks in each caudal-fin lobe usually present in T. atronasus . Tympanopleura longipinna further differs from T. cryptica in having a greater number of pectoral-fin rays (10-13, mode 11 vs. 8-10, mode 9), fewer preanal vertebrae (13-15, mode 14 vs. 14-15, mode 15), more total vertebrae (40-43, mode 43 vs. 38-41, mode 38), shorter preanal length (49.7-57.6% SL vs. 59.6-66.0% SL), shorter prepelvic length (38.8-48.4% SL vs. 48.3-53.6% SL), greater distance from dorsal- to adipose-fin origin (46.5-54.0% SL vs. 33.9-46.7% SL), longer anal-fin base (33.9-39.9% SL vs. 24.4-30.3% SL), slightly smaller eye diameter (11.6-18.5% HL vs. 16.7- 25.6% HL), and a generally lighter pigmentation pattern on the head, dorsum, body, and fins. Tympanopleura longipinna differs from T. brevis in having an overall greater number of anal-fin rays (32-42, mode 37 vs. 31- 36, mode 33) and total vertebrae (40-43, mode 43 vs. 38- 41, mode 40), greater distance from pelvic- to adipose-fin origin (37.6-45.1% SL vs. 31.2-38.3% SL), shorter pectoral-fin spine (15.9-18.2% SL vs. 19.1-24.4% SL), longer anal-fin base (33.9-39.9% SL vs. 26.6-33.9% SL), shorter head length (25.2-29.7% SL vs. 29.7-35.6% SL), and usually lighter pigmentation pattern on the head, dorsum, sides of the body, and fins ( vs. diffuse, dark tan to brown pigment extending well below the lateral line and paired fins with dark membranes). Tympanopleura longipinna differs from T. piperata in having a greater number of pectoral-fin rays (10-13, mode 11 vs. 6-10, mode 9), more gill rakers on the first arch (19-25, mode 23 vs. 16-23, mode 19), fewer preanal vertebrae (13-15, mode 14 vs. 14-16, mode 15), more total vertebrae (40-43, mode 43 vs. 39-41, mode 40), greater body width at the pectoral-fin origin (21.1- 25.7% SL vs. 16.8-20.0% SL), smaller eye diameter (11.6- 18.5% HL vs. 24.3-35.7% HL), gas bladder with two short posterior diverticula ( vs. diverticula absent), and lack of a dense band of pigmentation on the base of the caudal fin. Tympanopleura longipinna differs from T. rondoni in having more anal-fin rays (32-42, mode 37 vs. 28-37, mode 31), fewer gill rakers on the first arch (19-25, mode 23 vs. 24-33, mode 29-30), fewer preanal vertebrae (13-15, mode 14 vs. 14-16, mode 15), more total vertebrae (40-43, mode 43 vs. 38-42, mode 40), shorter predorsal length (29.5- 36.1% SL vs. 35.2-47.4% SL), greater distance from dorsalto adipose-fin origin (46.5-54.0% SL vs. 38.1-46.8% SL), longer anal-fin base (33.9-39.9% SL vs. 23.1-32.5% SL), a cordiform gas bladder with two short posterior diverticula ( vs. gas bladder elongated antero-posteriorly and with two longer, recurved posterior diverticula), and an overall light pigmentation pattern on the head, dorsum, sides of body, and fins ( vs. dark pigmentation over most of body and fins with prominent spots or mottling).
