Scientific Details

Head laterally expanded, its posterior part immersed in first pereonite. Eyes lateral, week. First antennae larger than or almost as large as second antennae, with single or two-segmented flagellum. Coxal plates marked off dorsally only on last three pereonites. Maxillipeds with four-segmented palp. Pereopods 1-3 subchelate but article 6 not swollen. Pereopods 4-7 not especially long, dactyls present. Remaining pereopods may have the dactyl absent or reduced to a very short spine. Pleon of 3 free sornites, plus pleotelson. Uropods biramous.

General Description

White body tapers to an acute pleotelson and has sculptured rows of knobs. The uropods are underneath and enclose the gills. The eyes are weak black spots on the broad head. Up to 11 mm long.

Biology

The southern chaetiliid lives on the surface of sand between 4 and 100 m depth in southern Port Phillip Bay and Bass Strait. Nothing is known of the biology of this species. It belongs to one of the valviferan families (like Idoteidae and Arcturidae) whose uropods form a chamber enclosing the fragile gills. Like many crustaceans living in course sands the legs are very spiny.

Habitat

Intertidal sediments, depths of 4-100 m.
