Type species. Oisedicus maginus sp. n. Diagnosis. Head arcuately curved ventrad. Lateral portion of pronotum distinctly widened. Fore wing with stem Sc+R forked at ½ from base. Hind wing with common stem Sc+R+CuA; vein CuA visible, as long as terminals R1 and Rs. Remarks. This genus differs from other genera by a unique combination of characters: stem Sc+R forked at ½ from base; hind wing with common stem Sc+R+CuA as long as terminals R1 and Rs. From the recent genus Aleurodicus it differs by antennae 8-segmented (7-segmented in Aleurodicus ), and hind wing venation (short common stem of Sc+R and CuA, shorter than terminals R1 and Rs in Aleurodicus ). Oisedicus and Aleurodicus are somewhat similar in the late forking of the fore wing Sc+R+CuA stem. Etymology . Generic name is a combination of the name of the river Oise and suffix ~ dicus (from the generic name Aleurodicus ). Gender masculine.
