ResumoDoesburg's hypothesis or eight mimetic complexes in the Neotropical Dysdercus species (Pyrrhocoridae), based on shared forewing coloration, is reanalysed. The complex or sim lar and sympatric species which works to deter predators should be distinguished from a complex which has been evolved to deter them. To be considered mimetic, consequently, a complex should comprise species that (a) are actually aposematic, (b) have apomorphic coloration, (c) do not have an exclusive common ancestor (are non-monophyletic), and (d) are actually sympatric. If the assumed mimetic complex does not pass all tests for mimesis, the hypothesis that it has been evolved under pressure or «mimesis-forming selection» is round to be false, regardless or the present ecological function or the complex. By historical-ecological analysis, the hypothesized mimetic origin of all but two of Doesburg's complexes is disproved
