Propsilocerus Kieffer, 1923 shares morphological synapomorphies with Prodiamesinae

Abstract

In their comprehensive analysis Cranston et al. (2012) quite unexpectedly recovered a monophyletic Orthocladiinae, except that Propsilocerus Kieffer, 1923, was recovered as a representative of Prodiamesinae. In this short communication I show that Propsilocerus shares morphological synapomorphies with other Prodiamesinae – namely (i) an indirect tracheal connection of the pupal thoracic horn to the adult spiracle and (ii) a parallel-sided rami of female gonapophysis IX.
