Abundant remains of the cyrtosymboline Osmolskabole neptis and "Osmolskabole prima" were recovered from the middle Famennian of the Moravian Karst (Czech Republic). They reveal that the two morphologies supposedly characterizing the two taxa are in fact two extremes of a morphological continuum. This suggests that “O. prima” is a subjective junior synonym of O. neptis. An almost complete articulated specimen of this species indicates that the 10 thoracic segments probably characterized early cyrtosymbolines, confirming that they belong to the Proetidae. A possible evolution of the Phillipsiidae from the Proetidae via the Cyrtosymbolinae is also discussed. .
