In 1927, R. de Lessert considered Philaeus manicus to be the same species, making it a junior synonym of Pachypoessa albimana.

In 1987, Jerzy Prószyński further synonymized Pachypoessa albimana with Euophrys plebeja.

Philaeus manicus is treated as a separate species in the genus Nigorella, N. manica.

Euophrys plebeja is regarded as a doubtful name (nomen dubium).
