Abstract
Pseudosida szalayi Daday, 1898 is redescribed on the basis on type material from Sri Lanka (Ceylon) and other materials from India, Bangladesh, Indonesia, East and South China, and Far East of Russia (Lower Amur River basin). The investigation of intraand interpopulational morphological variability has allowed coming to the conclusion about the conspecificity of specimens from different regions and occurrence of the only species, P. szalayi, in East and South Asia. The male of the species is described in detail for the first time. The first discovered northernmost localities of the species in the Lower Amur River basin are far separated from others and may have a relict status. While probably, only one species of the genus occurs in East and South Asia, the taxonomic status of African pseudosidas known under the names “P. szalayi” and “P. bidentata” remains uncertain.References
