Issue
Mitochondrial D-loop sequences used in a molecular phylogeny of Hypostomus and related genera by Montoya-Burgos and Weber (in press, fig. 2; EMBL/GenBank AJ318350). Biology: collected in transparent water, substrate composed by large rocks on fine sand, clay or shingle. No aquatic vegetation but leaves and dead woods. Water characteristics: depth of water: 20-200 mm., temperature 25-26°.
