03F187D1FFBD93515642A12CFA52F980.taxon	description	Hoplias malabaricus from the Araguaia River basin The specimens collected in São Miguel do Araguaia had 2 n = 42 chromosomes (18 m + 24 sm) and FN = 84 in both males and females, with no chromosome heteromorphism related to sex. Heterochromatin was found distributed in the pericentromeric and terminal region in several chromosomes of the complement. Submetacentric pair 10 clearly stood out, with a large band in the pericentromeric region; pairs 14 and 20 had conspicuous bands in the terminal region of the long arm, which were co-localized with the Ag-NORs (Fig. 1 d, e, f). FISH with the 5 S rDNA probe revealed only one small metacentric pair (n 8) labeled in the interstitial region of the long arms (Fig. 2 d). 18 S rDNA sites were labeled in three pairs of submetacentric chromosomes: one large pair (n 10) in the region near the centromere and two smaller pairs (n 14 and 20) in the terminal region of the long arms. Moreover, only one of the homologues of pair 10 had an extra site, which was in the terminal region of the long arm (Fig. 2 e). FISH with the 5 S Hind III satellite DNA probe identified eight chromosome pairs with sites in the centromeric region: two metacentric pairs (n 1 and 5) and six submetacentic pairs (n 10, 11, 12, 15, 16 and 21) (Fig. 2 f). Hoplias malabaricus from the basin of the Xingu River The specimens collected from the tributaries of the Sete de Setembro River had 2 n = 42 chromosomes (20 m + 22 sm) and FN = 84 for both males and females, with no heteromorphic sex chromosome system. C-banding revealed pericentromeric bands in nearly all the chromosomes as well as small terminal bands on some pairs. Silver nitrate staining revealed three chromosome pairs (n 4, 9 and 15) withAg-NORs (Fig. 1 g, h, i). FISH with the 5 S rDNA probe revealed only one metacentric pair (n 8) labeled in the interstitial region of the long arms (Fig. 2 g). 18 S rDNA sites were labeled in the terminal region of the long arms in three pairs of chromosomes: two metacentric pairs (n 4 and 9) and one submetacentric pair (n 15) (Fig. 2 h). FISH with the 5 S Hind III satellite DNA probe identified 10 chromosome pairs with sites in the centromeric region: four metacentric pairs (n 1, 5, 7 and 10) and six submetacentric pairs (n 11, 12, 13, 16, 17 and 19) (Fig. 2 i).	en	Blanco, Daniel Rodrigues, Lui, Roberto Laridondo, Bertollo, Luiz Antonio Carlos, Margarido, Vladimir Pavan, Filho, Orlando Moreira (2010): Karyotypic diversity between allopatric populations of the group Hoplias malabaricus (Characiformes: Erythrinidae): evolutionary and biogeographic considerations.
