Dorsum. Propodosomal shield with three pairs of setae. A pair of eyes located between setae ve and sci. Apodemal marking absent. Setae sce located on auxiliary shields. Central shield with three pairs of setae. Setae d 2 located on marginal shields and setae e 2 located on lateral zonal shields. Intercalary shield divided, with setae f 1. Suranal shield entire, with two pairs of setae. Dorsum with reticulum. vi, sci and h 1 faintly spinulate distally. Setae h 2 faintly spinulate. Other dorsal body setae flagelliform.

Venter. Setae c 2 placed on humeral shields. Coxisternal shields separated, bears three pairs of setae. Aggenital shield with three pairs of setae. Surfaces of coxae, coxisternal and aggenital shields with reticulum. Contiguous genital and pseudanal covers bearing four pairs of setae (g 1, ps 1, ps 2, ps 3).

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).
