Última A new species of Acestridium Haseman, 1911 (Loricariidae: Hypoptopomatinae) from the Eastern Amazon basin, Brazil Neotropical Ichthyology Rodriguez,Mónica S.; Reis,Roberto E.. Acestridium triplax, new species, is described from the Amazon River basin in Pará State, Brazil. The new species can be distinguished from all its congeners by having one series of middle abdominal plates between the lateral abdominal plates (vs no abdominal plates between the lateral abdominal plates).

Ano: 2007 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252007000400001 Phylogenetic relationships of the species of Acestridium Haseman, 1911 (Siluriformes: Loricariidae) Neotropical Ichthyology Rodriguez,Mónica S.; Delapieve,Maria Laura S.; Reis,Roberto E.. A phylogeny of the species of the loricariid genus Acestridium and relevant outgroups is presented based on a parsimony analysis of 52 unweighted and unordered morphological characters. Acestridium is diagnosed as monophyletic based on the possession of the 17 exclusive synapomorphies. Two primary trees were found, and the strict consensus among those alternative trees resulted in the following relationships: ((A. dichromum + A. triplax)(A. gymnogaster + A. scutatum + (A. discus (A. colombiensis + A. martini)))). Acestridium was found to be sister to Niobichthys with this clade subsequently the sister-group to Oxyropsis + Hypoptopoma.

Ano: 2015 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252015000200325 Taxonomy of Ixinandria Isbrücker & Nijssen (Loricariidae: Loricariinae) based on morphological and molecular data Neotropical Ichthyology Rodriguez,Mónica S.; Cramer,Christian A.; Bonatto,Sandro L.; Reis,Roberto E.. The genus Ixinandria was described in 1979 to include I. steinbachi from the upper río Juramento in northern Argentina and I. montebelloi from the upper río Bermejo in southern Bolivia. We used a multivariate morphometric analysis (Principal Components Analysis) and a molecular comparison of the Cytochrome Oxidase I gene to investigate variation among distinct populations from the known distribution range of both species. We conclude that the populations are not significantly distinct and do not deserve separate species recognition, and we place I. montebelloi in the synonymy of I. steinbachi.
