“…The Brazilian fossil from the Mio-Pliocene ( † Paleohoplias assisbrasiliensis) belonging to the family Erythrinidae demonstrates how old this group of Neotropical teleost fish is (Gayet et al, 2003), existing for at least five million years. This observation, together with a host of other important characteristics of H. malabaricus, such as (a) broad geographic distribution in the hydrographic basins of South America , (b) the formation of isolated populations in the same hydrographic basin due to geological events (formation of waterfalls, large rapids or lakes), (c) …”

“…Erythrinidae is a small family of Neotropical teleost fish, widely distributed throughout South America, currently made up of three genera -Hoplerythrinus, Erythrinus and Hoplias -and an extinct genus -Paleohoplias assisbrasiliensis (Gayet et al, 2003). Hoplias is the most widely spread genus on the South American continent, comprising two large groups: H. malabaricus and H. lacerdae.…”

Three populations of the group Hoplias malabaricus from the hydrographic basins of the São Francisco, Araguaia/Tocantins and Xingu Rivers in Brazil were analyzed using classic cytogenetic methods (Giemsa staining, C-banding and Ag-NORs) and molecular methods (fluorescent in situ hybridization with 18S rDNA, 5S rDNA and 5SHindIII satellite DNA probes). The chromosome markers allowed the characterization of these populations as belonging to karyomorph A and the detection of inter-population divergences. These differences likely stem from different evolutionary histories resulting from geographic isolation between populations associated to the dispersive mode of these organisms, reinforcing genetic diversity in the group Hoplias malabaricus.Três populações do grupo Hoplias malabaricus das bacias hidrográficas dos rios São Francisco, Araguaia/Tocantins e Xingu foram analisadas citogeneticamente utilizando-se métodos clássicos (coloração com Giemsa, bandamento-C e Ag-RONs) e moleculares (hibridização in situ fluorescente com sondas de rDNA 18S, rDNA 5S e DNA satélite 5SHindIII). Os marcadores cromossômicos foram fundamentais para a caracterização destas populações como pertencentes ao cariomorfo A e para detecção de claras divergências interpopulacionais. Estas diferenças são provavelmente oriundas de diferentes histórias evolutivas do isolamento geográfico entre as populações associado ao modo dispersivo destes organismos, reiterando a diversidade genética do grupo Hoplias malabaricus.

-A new species of turtle, Stupendemys souzai, is based on one incomplete humerus and additional material from several outcrops of the Solimões Formation in the state of Acre. Diagnostic features of the species include the humerus noticeably less massive than in Stupendemys geographicus, the thick curved margin of the nuchal and peripheral 1 plates, the femoroanal sulcus located very anteriorly on the xiphiplastral plate, the posterior lobe of the plastron short and broad and the centrum of cervical vertebrae relatively narrow and excavated laterally.
