Comments. Spassky & Shnitnikov (1937) described a new subspecies for the population of Dictyna latens occurring near Almaty (“ D. latens Fabr. mutabilis, forma nova”). According to Spassky and Shnitnikov (1937), this population differs from the nominotypical subspecies by the highly variable dorsal abdominal pattern and intensity of colour. No differences have been found in the copulatory organs. Specimens from East Kazakhstan exhibited also variability in the dorsal pattern and the intensity of colour. Specimens examined from Europe also show this variability in pattern, and vary from completely black to whitish with black folium.
Direct comparison of East-Kazakhstan specimens with those from Ural or Azerbaijan has revealed no differences in structure of the copulatory organs, as well as in any somatic characters. Therefore, we synonymize D. latens mutabilis with the nominotypical subspecies.
Note. Dictyna latens mutabilis has been overlooked by arachnologists therefore it was not mentioned in Roewer’s catalogue (Roewer 1942) and subsequent catalogues of Brignoli (1983), Platnick (1993, 1997 and internet versions from 0 to 15, 2000–2014) and World Spider Catalog (2014).
Distribution. This species is known from the Iberian Peninsula (Helsdingen 2014) to East Kazakhstan Area (present data).
