Most parsimonious tree for subgeneric relationships of Zethus recovered from New Technology Searches using Implied Weights with k = 14.067383. Numbers below nodes indicate GC values of Symetric Resampling. Terminals labeled in current classification. Z. (Z) = Z. (Zethus); Z. (Zds) = Z. (Zethoides); Z. (Zcl) = Z. (Zethusculus). Shaded clades indicate newly proposed classification.
