FIGURE 18 in Nebria tenuicaulis sp. nov., a sympatric species with Nebria sadona ohdaiensis Nakane, with studies on the phylogeny of the subgenus Sadonebria Ledoux & Roux (Coleoptera: Carabidae)

FIGURE 18. Phylogeny and possible character evolution of the subgenus Sadonebria, based on single most parsimonious tree obtained by the equal­weighting analysis. Numerals below branch indicate bootstrap value (where>50%) and Bremer support (in parentheses). Numbers in the squares indicate characters in Appendix 2, and numbers above the squares indicate character­state changes. Black squares indicate unambiguously optimized characters. White squares indicate characters optimized with ACCTRAN and DELTRAN optimizations (marked with '(a)' and '(d)', respectively).
