, we limit our discussion to two characters; discussion on telson setae is provided above. The most common setal pattern of dactyli of pereopods III–VII consists of tiny seta and spiniform seta at the base of nail. Additional spines may appear, but the pattern of appearance differs from species to species: in some cases these extra spiniform setae are present on all pereopods, or only on dactyls III–IV, sometimes only on dactyls V–VII, VI–VII or exclusively on dactyls VII. In addition, pereopods III–IV are morphologically different from pereopods V–VII. Different setal patterns and overall appendage morphology implies that evolution of seta on pereopods III–IV differs from evolution of pereopods V–VII. This is the reason why we treat the “same” dactylar pattern as two independent characters. On the other hand, lumping different patterns of setal patterns on pereopods V–VII may be an oversimplification; however, the comparative aspect of the study is not weakened.
