Description. Male (holotype from Barmah State Forest, Victoria; WAM T65677):
Prosoma, dorsal shield. Dorsal profile straight in lateral view; shiny dark brown to black; very indistinct darker radial pattern (Fig. 13); narrow light median band; covered with sparse black setae, white setae in median band and between PE; black macrosetae around eyes, in particular PE.
Eyes. Row of AE procurved and shorter than row of PME.
Sternum. Shiny dark brown to black; black setae which are denser and longer towards margins.
Labium. Dark brown; front end truncated and white.
Chelicerae. Brown­black; covered with black setae which are densest and longest basolaterally; three promarginal teeth, the median largest; three retromarginal teeth of similar size.
Pedipalps (Figs 15–18). Prolateral tegular lobe longer than the triangular, membranous tegular apophysis; embolus long and slender, in resting position sitting in cavity of terminal apophysis; terminal apophysis with two lateral tips (Fig. 18).
Opisthosoma. Very dark grey; light median longitudinal band with a cover of white setae; otherwise sparse black setae (Fig. 13). Venter grey, slightly lighter than dorsally, covered with silver­grey setae. Spinnerets black.
Legs. Leg formula VI>I>II>III; coxae distally yellow­brown, femora black, femora II–IV with basal yellow annulation that increases in width from leg II–III; tibiae brown with central light annulation; metatarsi and tarsi brown. Spination of leg I: femur: 2 dorsal, 1 apicoprolateral; patella: 1 apicodorsal; tibia: 2 ventral pairs, 1 retrolateral; metatarsus: 3 ventral pairs.
Female (paratype from Lake Eppalock, Victoria; WAM T70050):

Distribution. South­eastern Australia, including New South Wales, South Australia and Victoria (Fig. 21).
Life history and habitat preferences. Anomalosa oz sp. nov. appears to prefer similar habitats to A. kochi, such as creek banks and the borders of lakes and dams. For example, I have caught this species, including females carrying eggsacs, running in cracked mud with rocks near the water of Lake Eppalock in Victoria. Other habitat descriptions include grassy areas and open woodland. Anomalosa oz sp. nov. was frequently caught in pitfall traps during a survey of Victorian Box­Ironbark woodlands (E ucalyptus microcarpa, E. polyanthmos, E. melliodora, E. goniocalyx, E. sideroxylon, E. tricarpa) by the Museum Victoria. One record from Castle Creek in Victoria (MV K8114) supports at least temporary web­building behaviour, since the spiders were caught in sheetwebs in an ephemeral wetland.
Most spiders, males and females, where caught in pitfall traps exposed in November and December. Occasional records are from February, April and August.
