Tree comparisons. (a) Interrelationships of investigated taxa obtained by pruning the phylogenetic tree of Kenaley et al. (2013). We further mapped our characters on this tree (tree length: 33). (b) Single most parsimonious tree obtained from an exhaustive search performed using the data matrix given in Table 9 and rooted on Sigmops elongatus (N = 1, tree length 28, CI = 0.79, RI = 0.65). Blue circles, synapomorphies; red circles, convergences; yellow circles, reversals
