Orphnus longicornis Frolov et Akhmetova

 

Diagnosis. Males of O. longicornis with well-developed head and pronotum armature can be separated by a very long, slender clypeal horn (almost 1.5 longer than head width) and a protruding, tubercle-shaped basal margin of pronotum. Males with less developed armature are similar to the males of O. luminosus Benderitter in habitus, punctation, and slight metallic tint of the body but they can be separated from the latter by the shape of the parameres which are longer, more curved downward, and more acute apically.
