NOTES: Sciapus is known from the Nearctic, Palearctic, and Oriental realms ( Bickel, 1994). In the Palearctic region, species of this genus are found in abundance in dry sandy areas and dry forests (Pollet, unpubl. data). Most species occur on tree trunks and other vertical surfaces, whereas other species are mainly soil­dwelling in dry habitats like coastal dunes and dry heathland. Two species, S. pallens and S. wiedemanni , occur in both the Nearctic and Palearctic regions. The distribution of S. wiedemanni suggests accidental human introduction.
