03B68793FFFDEE50E102FB04FC63FA71.taxon	description	Araguaia River basin. Diploid number was 58 chromosomes and karyotype was composed of 20 metacentric, 18 submetacentric, 12 subtelocentric, and 8 acrocentric (Fig. 1 B). AgNO 3 staining revealed simple NORs allocated in the terminal region on the short arm of the submetacentric pair 24 (Fig. 1 B, in box). C-banding evidenced pale heterochromatin in terminal regions of almost all chromosome pairs (Fig. 1 E). 18 S rDNA-FISH confirmed previous finding by AgNO 3 staining, simple NORs on pair 24. 5 S rDNA-FISH detected these sites on short arm of the metacentric chromosome pair 3 (Fig. 1 H).	en	Santos, Dayane Petik dos, Felicetti, Denise, Baumgärtner, Lucas, Margarido, Vladimir Pavan, Blanco, Daniel Rodrigues, Moreira-Filho, Orlando, Lui, Roberto Laridondo (2021): Contributions to the taxonomy of Trachelyopterus (Siluriformes): comparative cytogenetic analysis in three species of Auchenipteridae.

03B68793FFFDEE50E2ECFD62FD57FB81.taxon	description	Doce River basin. Diploid number (2 n) was 58 chromosomes and the karyotype was composed of 18 metacentric, 20 submetacentric, 10 subtelocentric, and 10 acrocentric chromosomes (Fig. 1 A). AgNO 3 staining demonstrated simple NORs allocated in terminal region on the short arm of the submetacentric pair 23 (Fig. 1 A, in box). C-banding technique evidenced pale heterochromatin in terminal regions of almost all chromosome pairs (Fig. 1 D). 18 S rDNA-FISH confirmed previous findings by AgNO 3 staining and revealed these sequences only on pair 23. 5 S rDNA-FISH detected these sequences in three submetacentric pairs, on the short arm of the pair 10 and 13, and on the long arm of the pair 15 (Fig. 1 G).	en	Santos, Dayane Petik dos, Felicetti, Denise, Baumgärtner, Lucas, Margarido, Vladimir Pavan, Blanco, Daniel Rodrigues, Moreira-Filho, Orlando, Lui, Roberto Laridondo (2021): Contributions to the taxonomy of Trachelyopterus (Siluriformes): comparative cytogenetic analysis in three species of Auchenipteridae.

03B68793FFFDEE50E102FA55FC1AF8CC.taxon	description	Araguaia River basin. Diploid number was 58 chromosomes and karyotype was composed of 20 metacentric, 18 submetacentric, 12 subtelocentric, and 8 acrocentric (Fig. 1 C). AgNO 3 staining revealed simple NORs allocated in terminal region on the short arm of the submetacentric chromosome pair 23 (Fig. 1 C, in box). C-banding evidenced pale heterochromatin in terminal regions on almost all karyotype pairs (Fig. 1 F). 18 S rDNA-FISH also revealed only the pair 23 with these sites, corresponding to what was evidenced by the AgNO 3. 5 S rDNA-FISH probe detected these sites on the short arm of the metacentric pair 3 and on the long arm of the submetacentric pair 16 (Fig. 1 I).	en	Santos, Dayane Petik dos, Felicetti, Denise, Baumgärtner, Lucas, Margarido, Vladimir Pavan, Blanco, Daniel Rodrigues, Moreira-Filho, Orlando, Lui, Roberto Laridondo (2021): Contributions to the taxonomy of Trachelyopterus (Siluriformes): comparative cytogenetic analysis in three species of Auchenipteridae.
