An examination of the aedeagus of the holotype, however, revealed that  S. nidicolarepresents a distinct species and that it is conspecific with  S. splendidulus(BOHÁý 1988), which, accordingly, is synonymised with  S. nidicola. The forebody and the male sexual characters of the holotypeof  S. nidicolaare illustrated in Figs 2-6. For comparison see the illustrations of the holotypeof  S. splendidulusin ASSING (2008a). 1978-10-30 ZIN V. Kastcheev V. I. Gusarov & V. Assing 7 1052 2 holotype 1978-10-30 ZIN V. Kastcheev V. I.
