Diagnosis. Genital morphology of both male and female A. orientalis sp. nov. resembles that of A. joergi Framenau, 2007 , but the abdominal pattern in the new species is less distinct. Instead of the typical Artoriopsis -pattern with black diamond and posterior light patch, the abdomen of A. orientalis sp. nov. is uniformly dark olive grey with pairs of faint light spots in the anterior half and a faint posterior patch ( Figs 7A View Figure 7 , 8A View Figure 8 ). The tegular apophysis is shorter in A. joergi than in A. orientalis sp. nov. and the latter much more rounded apically. The median septum of the female epigyne in both species is short, but A. orientalis sp. nov. lacks the distinct atria present in A. joergi .
Description. Male (based on holotype, AM KS.84526).
Prosoma, dorsal shield ( Fig. 7A View Figure 7 ). Dorsal profile in lateral view straight; dark brown, with indistinct light median band, that is lightest posteriorly, and distinct lateral bands; dense white setae in lateral bands, less dense otherwise.
Eyes. Row of AE procurved, narrower than row of PME.
Sternum ( Fig. 7B View Figure 7 ). Dark brown, slight dark and light discolorations centrally, 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; to promarginal teeth of equal size; two retromarginal teeth equal size.
Legs. Leg formula IV>I>II>III; dark brown, metatarsi and tarsi I-II and basal parts of femora I–III yellow-brown.
Pedipalp ( Fig. 7C,D View Figure 7 ). Tegular apophysis broadening apically, with but tapering sharp tip bent basally ( Fig. 7C View Figure 7 ); embolus almost straight, terminal apophysis forms a trough under the embolus ( Fig. 7E View Figure 7 ).
Opisthosoma ( Fig. 7A,B View Figure 7 ). Uniformly dark olive-grey, anterior half with two to three pairs of small light spots, indistinct light elongate patch in posterior half. Venter olivegrey, densely covered with silverish setae. Spinnerets light olive-brown.
Measurements. TL 4.7, PL 2.4, PW 1.5. Eyes: AME 0.07, ALE 0.07, PME 0.20, PLE 0.14. Row of eyes: AE 0.43, PME 0.58, PLE 0.67. Sternum (length/width) 1.4/0.9. Labium (length/width) 0.27/0.22.

Prosoma, dorsal shield ( Fig. 8A View Figure 8 ). As male, but median band more distinct.
Eyes. Row of AE procurved, narrower than row of PME.
Sternum ( Fig. 4B View Figure 4 ). Dark brown mottled, shiny; brown bristles that are longer and denser towards margins.
Labium. As male.
Chelicerae. Dark brown, with brown macrosetae; to promarginal teeth of equal size; three retromarginal, the apical very small.
Legs. Leg formula IV>I>II>III; colouration as male.
Opisthosoma ( Fig. 4A,B View Figure 4 ). As male, but indistinct lanceolate cardiac mark present in anterior half. Venter mottled olive-grey, some silverish setae and few brown bristles. Spinnerets light olive-brown.
Epigyne, ventral view ( Fig. 4C View Figure 4 ). Median septum forming a short lip.
Epigyne, dorsal view ( Fig. 4D View Figure 4 ). Spermathecal heads almost globular, spermathecal stalks forming a 180-degree bend.
Measurements. TL 4.9, PL 2.6, PW 1.7. Eyes: AME 0.07, ALE 0.09, PME 0.20, PLE 0.16. Row of eyes: AE 0.38, PME 0.65, PLE 0.76. Sternum (length/width) 1.2/1.0. Labium (length/width) 0.29/0.23. OL 2.4, OW 1.7. Legs: Lengths of segments (femur + patella + tibia + metatarsus + tarsus = total length): Pedipalp 0.80 + 0.40 + 0.30 + — + 0.60 = 2.10, I 1.55 + 0.75 + 1.05 + 1.05 + 0.75 = 5.15, II 1.50 + 0.75 + 0.85 + 0.90 + 0.70 = 4.70, III 1.40 + 0.65 + 0.70 + 1.15 + 0.65 = 4.55, IV 1.90 + 0.75 + 1.40 + 2.00 + 0.90 = 6.95.
Etymology. The specific epithet is an adjective in apposition derived from Latin, orientalis —eastern, and refers to the eastern Australian distribution of the species.
Natural history and habitat preferences. All specimens were collected during pitfall trap studies in November and December, suggesting spring- to summer maturity of A. orientalis sp. nov. Most records are from farm or irrigation areas, some records detail “roadside” as habitat. It appears that the species is common in somewhat disturbed, open areas.
Distribution. The species is only known from New South Wales ( Fig. 2 View Figure 2 ).
