Stenaelurillus setosus is a possible species of jumping spider from Myanmar and Thailand.

[2] Stenaelurillus setosus was regarded as a nomen dubium (dubious name) by the World Spider Catalog as of January 2021[update].

On the opisthosoma there is a wide transverse whitish band at the front and a narrower one near the spinnerets.

[1] The genus name, Philotherus, was taken from Ancient Greek Φιλόθηρος ("fond of hunting"), taken from Persian mythology according to Thorell.

In 1981, Jerzy Prószyński transferred it to the genus Stenaelurillus, but regarded it as a nomen dubium (dubious name).
