Cydnus aterrimus (Forster, 1771)

Cydnus brunnipennis Fabricius, 1803 was erroneously synonymized with Macroscytus brunneus (Fabricius) by Fieber (1861a:: 362); then it was excluded from this synonymy by Signoret (1881e: 644). Reuter (1888a), who synonymized C. niger sinipes De Geer with Sehirus luctuosus, did examine De Geer’s type(s): sec. spec. typ.. Also Dolling et al. (1999), in their work about species described in Cimex, placed the unavailable name C.niger spinipes in synonymy with S. luctuosus.
