Figure 14 - Schematic of inferred evolutionary relationships of the Parvocythere species. Triangles coloured in gray indicate each group of species. Species in blackly closed squares indicate them classified into each group. The characters of antennula, antenna and male copulatory organ are represented in the blackly closed balloons and under-lined characters are novel ones. Evolutionary change is represented in an open balloon. The species in the second step of Group N have only one of the reductive states: reductive one of two antennal distal claws or one of pared male copulatory organ (with an asterisk "*").
