Figure 4 in The mid-Cretaceous †Lepiceratus Gen. nov. and the Evolution of the Relict Beetle Family Lepiceridae (Insecta: Coleoptera: Myxophaga)

Figure 4. Strict consensus tree of four most parsimonious trees obtained by analysis of morphological characters of Myxophaga with NONA (tree length 177 steps; consistency index ¼ 0.76; retention index ¼ 0.89); problematic †'Haplochelus' and † 'Lepichelus' excluded. Bremer support value indicated beneath branches; unambiguously optimized character changes plotted along the internodes (black circles indicate unique character changes; white circles indicate parallelisms or reversals; character numbers are above circles; character states are below circles). Examples of extant and extinct myxophagan beetles are illustrated on the tree, from upper left: †Lepiceratus ankylosaurus sp. nov.; Lepicerus mumia; Lepicerus bufo; Sphaerius acaroides; Hydroscapaha natans; and Satonius stysi.
