Two most parsimonius cladograms produced by the cladistic analysis of Paramisophria species.
Nota: Paramisophria species fall broadly into 4 groups, which are essentially simolar to the grouping proposed by Jaume & al. (2000).
The 1st group contains P. giselae, which differs from other species by the presence of a distal seta on the 1st praecoxal endite of Mx2.
The 2nd group contains P. japonica, which differs from the other congeners by having basal seta on tMx1 and an inner subapical seta on the endopod of female P5.
The 3rd group includes P. fosshageni, P. itoi0, P. galapagensis, P. intermedia, P. platysoma and P. bathyalis.
The 4th group includes P. ammophila, P. cluthae, P. variabilis, P. reducta, P. mediterranea and the two new species P. sinjinensis, P. koreana.
The topology of two parsimonius trees differed only in the positions of P. ammophila and P. cluthae relative to P. sinjinensis and P. koreana. P. ammophila clustered with two new species as a sister group (fig.12 A), by the absence of a seta on Mx1 coxal endite and the presence of a single copulatory pore ventrolaterally on the right side of the genital double-somite. This node is tentative, because there is no information on female P. sinjinensis.. However, the two new species also showed a sister-group relationship with P. cluthae (Fig.12 B), by the absence of a left endopod on male P5. The two new species appear to be relatively recent offshoots, because the male appendages exhibit a more apomorphic state (characters differing from an ancestral condition).
