Eoligiiscus , new genus

TYPE SPECIES: Eoligiiscus tarraconensis , new species .

DIAGNOSIS: Sex unknown. An oniscidean with the following unique combination of characters: Body size small (<2 mm), oval, with pleon not abruptly contracted; dorsal surface moderately convex, with epimeral plates only moderately prominent, smooth. Cephalon broad, not sunk into first pereonite. Eyes large and convex (with at least 10 ommatidia). Antenna rather stout, short, with flagellum composed of only four articles. Pereopods all alike, slender and cylindrical, armed with short thick spines; dactylus hirsute, with two claws; dactylar setae unbranched, quite short. Uropod greatly elongate, distinctly surpassing length of pleon; protopod long and stout, not produced inside pleotelson, with endopod and exopod inserted at same level; endopod and exopod styliform, exopod only slightly longer and stouter than endopod, each with a single apical spine.

ETYMOLOGY: The new genus group name is a combination of Greek Ἠώς ( Eos ), goddess of the dawn; Ligia Fabricius , type genus of the family; and the Greek suffix - iskos, a diminutive commonly applied as a suffix to woodlice generic names (as in Oniscus : itself a combination of Greek ὄνος [onos], meaning, “woodlouse”), and - iskos). The gender of the name is masculine.
