COMMENTS: Tychus assingi sp. n. is similar to T. rhodopeus Besuchet & Sabella, 1999 , from which it is distinguished by the shape of the antennomere IV slightly wider than long and V as wide as long (IV and V distinctly longer than wide in T. rhodopeus ) and by the different shape of the ventral portion of the aedeagal median lobe.
