Poecilaemula signata is a species of harvestman in the family Cosmetidae found in Central America.

[1] It was transferred to the current name combination of Poecilaemula signata (Banks, 1909) by Roewer (1912) [see Etymology below].

In Roewer (1912) the name was written as Poecilaemula signatum.

Later the species name suffix was subsequently altered (inflected to the feminine for gender agreement with the genus) in Roewer 1923, but using a variant (mis)spelling of the genus as Paecilaemula signata, which was repeated by several authors.

The current formation as Poecilaemula signata was given in the extensive catalog of Laniatores by Kury 2003.
