Artoria myallensis sp. n. Figs 29 E–H, 34 Myall Lakes Runner

Material examined.

Holotype male, Myall Lakes (32°26'S, 152°24'E, New South Wales, AUSTRALIA), September 1922, A. Musgrave (AM KS84055).

Other material examined.

Known only from holotype.

Etymology.

The specific name is an adjective in apposition derived from the type locality, Myall Lakes.

Diagnosis.

Males of A. myallensis sp. n. differ from all other Artoria by the deeply indented, three-lobed tegular apophysis (Fig. 29G). It appears most similar to A. belfordensis sp. n. (Fig. 9E), but it does not have the drawn out and pointed bases of the basoembolic apophysis of that species.

Description.

Male (based on holotype, AM KS84055).

Total length 3.9.

Prosoma. Length 2.2, width 1.5; carapace greyish with slightly dark radial pattern; indistinct lighter marginal band and v-shaped central band constricted between PME (Fig. 29E); sternum light brown, dusted dark grey (Fig. 29F).

Eyes. Diameter of AME: 0.10; ALE: 0.09; PME: 0.28; PLE: 0.21.

Anterior eye row. Slightly procurved, evenly spaced.

Chelicerae. Light brown.

Labium. Medium brown, with lighter anterior rim (Fig. 29F).

Pedipalp coxae. Medium brown, with lighter anterior rim (Fig. 29F).

Legs. Yellow-brown, with darker annulations; metatarsi and tarsi less annulated, lighter (Fig. 29E).

Opisthosoma. Length 1.7, width 1.2 dark grey with light yellow-brown anterior cardiac mark and light irregular pattern (Fig. 29E). Venter light brown with sparse darker pattern (Fig. 29F); spinnerets pale.

Pedipalps. Pedipalp globular, tibia as long as broad; cymbium tip with cluster of disto-ventral macrosetae (Fig. 29G, H); dorsal scopula patch sparsely present, short; tegular apophysis distally wide, deeply indented, basally narrowed to 1/3, retrolateral part widely scooped with two tips not reaching margin of cymbium (Fig. 29G); basoembolic apophysis about as long as broad, broadly rounded; not visible and not dissected as the holotype has only one pedipalp (Fig. 29G).

Female unknown.

Life history and habitat preferences.

Habitat preferences of A. myallensis sp. n. are not known. The holotype was found at the beginning of spring (September).

Distribution.

Artoria myallensis sp. n. is known only from the type locality, the coastal Myall Lakes in the southern NSW North Coast (NNC) IBRA region (Fig. 34).
