Eoligiiscus tarraconensis is an extinct species of woodlouse, the only species in the genus Eoligiiscus.

It was found preserved in amber at the Peñacerrada I amber site in Burgos, Spain.

The preserved specimens date from Late Albian period.

[1] The genus name comes from Eos, the Greek goddess of dawn; the related genus Ligia; and the Greek suffix -iskos, commonly used in wooldlouse genera names.

The species epithet comes from Roman province Hispania Tarraconensis; the site where the woodlouse was found lies within the historical boundaries of that province.
