Remarks. Currently, four species of Pylaemenes are recognized in Vietnam. A key to the females of the genus is provided. The female of P. abramovi sp. nov. is unknown and not sufficiently provided in the key. A key to the males of the genus is not provided because the males of P. konkakinhensis sp. nov. and P. guangxiensis (Bi & Li, 1994) are unknown.
