Fig. 4A–C

Holotype. Female , Canberra, c. 10–12 mi South (c. 35°18'S, 149°08'E, Australian Capital Territory, AUSTRALIA), 5–7 December 1969, H. Evans, A95, A96, spider wasp prey (AM KS.86418).

Other material examined. Only known from female holotype.

Diagnosis. Artoriopsis mulier sp. nov. is most similar to Artoriopsis eccentrica Framenau, 2007 , specifically in the shape of the epigyne. However, the median septum differs in both species widening slightly anteriorly in A. mulier sp. nov. and bulging centrally in A. eccentrica .

Description. Male unknown.

Female (based on holotype, AM KS.86418).

Prosoma, dorsal shield ( Fig. 4A ). Dorsal profile in lateral view straight; brown, with distinct light median and lateral bands; median band slightly broadening anteriorly, dense white setae in median and lateral bands, less dense otherwise; two bristles below AE.

Eyes. Row of AE slightly procurved, narrower than row of PME.

Sternum ( Fig. 4B ). Dark brown, shiny; brown bristles that are longer and denser towards margins.

Labium. Dark brown, shiny; front end truncated and white.

Chelicerae. Dark brown, with brown macrosetae; three promarginal teeth, the median largest; three retromarginal teeth of almost equal size.

Legs. Leg formula IV>I>II>III; yellow brown with dark annulations, particularly on femora.

Opisthosoma ( Fig. 4A,B ). Colouration poorly preserved, but apparently with typical Artoriopsis -pattern, i.e., black diamond-shaped mark centrally that is cut through by light lanceolate cardiac mark; posteriorly with rectangular light patch. Venter olive-brown. Spinnerets light olive-brown.

Epigyne, ventral view ( Fig. 4C ). Median septum narrow and slightly widening anteriorly.

Epigyne, dorsal view. Not examined, as only known from holotype.

Legs. Leg formula IV>I>II>III; yellow brown with dark annulations, particularly on femora.

Measurements. TL 5.9, PL 2.7, PW 1.9. Eyes: AME 0.13, ALE 0.09, PME 0.29, PLE 0.22. Row of eyes:AE 0.49, PME 0.70, PLE 0.90. Sternum (length/width) 1.3/1.0. Labium (length/width) 0.43/0.40. OL 2.7, OW 2.2. Legs: Lengths of segments (femur + patella + tibia + metatarsus + tarsus = total length): Pedipalp 0.55 + 0.40 + 0.40 + — + 0.85 = 2.20, I 1.60 + 0.75 + 1.00 + 1.05 + 0.75 = 5.15, II 1.50 + 0.75 + 0.90 + 0.90 + 0.70 = 4.75, III 1.40 + 0.75 + 0.90 + 1.05 + 0.60 = 4.7, IV 2.25 + 0.85 + 1.30 + 1.75 + 0.90 = 7.05.

Etymology. The specific epithet is a noun in apposition derived from the Latin mulier —woman, and refers to the fact that only a single female of this species is known.

Remarks. Whilst it remains possible that the female of A mulier sp. nov. is conspecific with A. lacustris sp. nov. or A. murphyi sp. nov., somatic details, specifically the patterns of the dark leg annulations do not match with either species.

Natural history and habitat preferences. Habitat preferences of A. mulier sp. nov. are elusive, as the holotype was found as prey of, based on the collection label, a “spider wasp”, possibly a member of the family Pompilidae Latreille, 1804 .

Distribution. Only known from the holotype female collected near Canberra, Australian Capital Territory ( Fig. 2 ).
