Conglobating Slaters

Non-convex endoantennal rolling isopods with short thickset antennae. Dorsal surface with prominent ornamentation. Frontal shield raised from vertex of head. Pleopods loose and overlapping with five pairs of pseudotracheae. Telson hourglass, uropod protopod long and tapering to distal margin.

This group includes all species that cannot be placed in any other genus of armadillid slaters.

Dorsoventrally flattened animal with prominent ornamentation. Frontal shield extending forward and uropod protopod much reduced in size.

Dorso-ventrally flattened with limited capacity for conglobation; light in colour with brown pigmentation on the pleon and pereonite 1.

Epimera horizontal. Schisma absent on the pereonal epimeron 1. Four pairs of pseudotracheae. Peopod exopodites 1-4 interlocking, 5th hidden by 4th. Uropod protopodite flattened and acute. Pleotelson hour-glass-shaped.

Convex with endoantennal conglobation ability. Pleopods 1 to 4 interlocking and interdependent, pleopod 5 covered by pleopod 4. Schisma present on posterior corner of pereonite 1.

Convex with endoantennal conglobation ability. Pleopods 1 to 4 interlocking and interdependent, pleopod 5 covered by pleopod 4. Schisma absent on posterior corner of pereonite 1. Frontal shield not divided by a transverse groove.

Frontal shield simple and raised from vertex of head (in WA species). Pereonal epimera 1 without schisma, but with simple endolobe on pereonal epimera 1 separated from lateral border. Pleopods wide and not interlocking or interconnected. Uropod protopods longer than wide.

Very small highly convex animal without pleopodal lungs and uropod exopodites.

Highly convex animal sometimes with dorsal setae. Thickened ventral margin of pereonal epimara 1, often with Sulcusmarginali. Peronite 1 with schisma Pereonal epimera 2 with well-developed tooth-like lobe. Telson not hourglass shaped with distal portion subrectangular.

Generally highly convex tiny animals with reduced or lacking pigmentation and with small or without eyes.
