Figure 6. Most-parsimonious tree (part two) from the EW analysis showing character state changes. Black rectangles represent unique changes and white rectangles represent homoplastic ones. Character numbers are indicated above branches and the corresponding state changes below the branches. Asterisks indicate type species of the genus. The position of Colletes clypeonitens is doubtful (see text). The Colletinae shown are (from top to bottom) Hemicotelles ruizii, C. cyanescens, C. nigritulus and C. slevini.
