The new genus Shuyushka gen. nov. is proposed and includes three species: Shuyushka achachay gen. et sp. nov., S. moscai gen. et sp. nov. and S. wachi gen. et sp. nov. Finally, five species are described in the genus Patrera Simon, 1903: P. hatunkiru sp. nov., P. philipi sp. nov., P. suni sp. nov., P. shida sp. nov. and P. witsu sp. nov.
