Fig. 10

Section of the Stevardiinae phylogeny showing the relationships in Diapomini (in part, continues in Figs. 8 and 9). ML tree obtained with RAxML. Single name labels several terminals when they lead to same nominal species. Type species of each genus are highlighted in green when sampled in this study. Red sperm symbols highlight taxa with insemination strategy, while blue sperm symbols highlight taxa known to have external fertilization. Sperm types are indicated by M1 – M3. Absence of any symbols next to taxon names indicates lack of knowledge about reproductive characters. Bootstrap values indicated with dots placed on internal branches according to inset caption. Section of the full topology shown on the left (shaded) is expanded on the right. Node 9 subtends Piabarchus distributed in Rio São Francisco basin and upper Paraguay (P. analis is type species). Node 10 subtends Piabina from the Rio São Francisco, upper Paraná and Paraguay basins (P. argentea is type species). Node 11 subtends Diapoma from the Paraná, Uruguay and coastal systems in southern Brazil (type species D. speculiferum)
