Tree obtained from the cladistics analysis of Ateralphus and related genera, Alphus and Exalphus. Only unambiguous transformations are shown. A and B show the differences between the two most parsimonious topologies. Bootstrap (gray box) and Bremer support (white box) are indicated below each node. Clades are illustrated by the following species: Alphus similis Martins, 1985; Grandateralphus variegatus comb. n.; Ateralphus subsellatus; and Exalphus leuconotus.
