Genus Leptoiulus Verhoeff, 1894

A large genus of over seventy described species which is almost exclusively European. Several subgenera have been denoted, and very many subspecific and infrasubspecific names have been suggested which are not listed here. Our interpretation of the species and names should, despite the valuable help of J.-P. Mauriès, be regarded as a preliminary one, to be tested by future revisionary work.
