03BE8798FA23FFF9FC75FD2047D2FD9F.taxon	diagnosis	Diagnosis. Rhamdia branneri differs from the remaining Rhamdia species, with exception of R. voulezi, and Rhamdia cf. quelen from rio Tibagi by having both sides anterior and posterior of the pectoral-fin spine serrate in large dents (vs. slightly serrate in fine dents in Rhamdia cf. quelen). Rhamdia branneri is also distinct by its dorsal-fin length not reaching the origin of the adipose fin when adpressed (vs. adpressed dorsal fin reaching adipose-fin origin in R. voulezi and R. cf. quelen); maxillary barbel short not reaching the origin of adipose fin (vs. maxillary barbel long, surpassing adipose fin origin in R. voulezi and longer than the SL in R. cf. quelen); R. branneri dorsal profile straight between the snout and supraoccipital process and convex from this point to the dorsal fin insertion (vs. dorsal profile almost straight from tip of snout to dorsal-fin insertion in R. voulezi and R. cf. quelen). Ground color of preserved R. branneri specimens dark or light gray with few large spots and without small black dots over trunk (vs. ground color grayish on dorsum to light orange on abdomen in R. voulezi and dark brown spotted in R. cf. quelen); dorsal-fin without a hyaline horizontal stripe immediately dorsal to base (vs. a hyaline horizontal stripe higher to base of dorsal fin in R. voulezi and R. cf. quelen). Differs in corporal proportions from R. voulezi in the higher distance between dorsal and adipose fins; higher distance between adipose ending and caudal fin base; higher distance between orbit and opercular bone and larger scapular bridge width; R. branneri also differs in chromosome number and morphology: 2 n = 58 - 62 chromosomes, plus one submetacentric B chromosome and multiple NOR system (vs. 2 n = 58 - 60 plus one metacentric B chromosome and a simple nucleolus organizer region (NOR) in R. voulezi). Rhamdia branneri differs from R. voulezi, R. foina (Müller & Troschel, 1849) and R. itacaiunas Silfvergrip, 1996 by having 9 - 14 gill rakers (mode 10) on the first gill arch (vs. 9 - 14, 12 in mode in R. voulezi; 15 - 20 in R. foina and 5 - 7 in R. itacaiunas); differs from R. laukidi Bleeker, 1858 by having absence of a diagonal light bar from superior corner of operculum to base of pelvic fin; R. branneri also differs from R. xetequepeque, R. jequitinhonha Silfvergrip, 1996, R. muelleri (Günther, 1864) and R. poeyi Eigenmann & Eigenmann, 1888 by having shorter orbital diameter: 12.9 - 17.6 % of HL (vs. 12.1 - 20.2 % in R. voulezi, 30.5 - 36.9 % in R. xetequepeque, 20.4 % in R. jequitinhonha, 12.1 - 27.2 % in R. muelleri and 20.1 - 26.2 % in R. poeyi). Rhamdia branneri is further distinguished from R. jequitinhonha by their longer caudal peduncle (18.4 - 21.8 % SL vs. 16.3 %) and longer interorbital distance: R. branneri 30.1 - 41.8 % HL (vs. 29.8 - 39.9 % in R. voulezi, 24.2 % in R. muelleri) and by its shorter maxillary barbel length: 129.9 - 213 % in R. branneri (vs. 178.5 - 374.2 % in R. voulezi, and 73.9 - 129.0 % in R. muelleri). It differs from R. poeyi by strong and well developed serrae on both sides of pectoral spine (vs. serrae just on posterior margin of pectoral spine); R. branneri also differs by a rounded margin of lower lobe (vs. longer and pointed lower caudal fin lobe in R. poeyi).	en	Garavello, Julio Cesar, Shibatta, Oscar Akio (2016): Reappraisal of Rhamdia branneri Haseman, 1911 and R. voulezi Haseman, 1911 (Siluriformes: Heptapteridae) from the rio Iguaçu with notes on their morphometry and karyotype.
