Oniscidae

 Hanoniscus sp., from Bennelongia.

Belongs within: Crinocheta.

The Oniscidae are a group of terrestrial isopods with a well-developed frontal line across the head. Members of the genus Oniscus have a flattened, elliptical body with prominent anterolateral processes on the head and an elongate telson (Muchmore 1990).

Characters (from Vandel 1973): Cephalon with strongly marked frontal line, with three projecting frontal lobes, one medial and two lateral; supra-antennal line generally well developed, sometimes reduced or absent. Pleurepimeres with ovoid glandular fields, usually small in size, rarely elongated. Pleon continuing directly into pereion without interruption; neopleura large, spreading, falciform. Antennal flagellum consisting of three articles. Endite of maxilliped without penicil. Genital apophysis simple, not bifurcated.
