Figure 9 in A Heterolepidoderma and Halichaetoderma gen. nov. (Gastrotricha: Chaetonotidae) riddle: integrative taxonomy and phylogeny of six new freshwater species from Central Europe

Figure 9. SIMMAP reconstruction of the absence/presence of a lateral denticle in chaetonotids based on 10 000 stochastic character maps simulated under the ARD model. Although the absence of lateral denticles is conditionally connected with the loss of spines, this side spine structure is not developed in any spined member of the Heterolepidoderma s.l. clade. Relative proportions of character states were mapped onto the best scoring ML tree.
