Distribution. Russia ( Kuznetsov 1977a) and Turkey (this paper).

Remarks. Stigmaeus solidus was known only from Russia ( Kuznetsov 1977a). This is the second record of this species. In the description given by Kuznetsov (1977a), the dorsum was without eyes and post-ocular bodies, but the presence of these structures was confirmed by Dr. Aleksandr Khaustov ( Ukraine), who examined the holotype of S. solidus ( Figure 23 A).
