Etymology.

Species name is a patronym in honour of Mr Graham Milledge, the Collection Manager of the Australian Museum, Sydney, for his support of this and many other of the present authors’ studies on Australian spiders.

Diagnosis.

Males of Artoria grahammilledgei sp. n. are most similar to those of A. terania sp. n., but the tegular apophysis of Artoria grahammilledgei sp. n. is lobed apically (Fig. 22I) (while not as elongated as in A. slatyeri sp. n. (Fig. 36C)), whereas it is truncated in A. terania sp. n. (Fig. 39E). The epigyne’s atrium is almost rectangular about as wide as long with two concave lateral edges and huge spermathecae (Fig. 22G, H).

Description.

Male (based on holotype, AM KS127756).

Total length 5.8.

Prosoma. Length 3.3, width 2.5; carapace light yellow-brown with dark radial pattern and black V-shaped pattern between cephalic and thoracic region; indistinct and irregular broad lighter central band (Fig. 22A); sternum pale, margin dusted dark grey (Fig. 22B).

Eyes. Diameter of AME: 0.14; ALE: 0.13; PME: 0.41; PLE: 0.32.

Anterior eye row. Slightly procurved, evenly spaced.

Chelicerae. Dark brown.

Labium. Dark brown, with lighter anterior rim (Fig. 22B).

Pedipalp coxae. Dark brown, with lighter anterior rim (Fig. 22B).

Legs. Light yellow brown with slightly darker annulations. (Fig. 22A).

Opisthosoma. Length 2.5, width 1.8; dark grey with light anterior cardiac mark and light grey irregular pattern mainly in anterior half (Fig. 22A). Venter dark grey with lighter pattern laterally (Fig. 22B); spinnerets dark grey.

Pedipalps. Tibia longer than broad; cymbium tip without macrosetae (Fig. 22E, F); dorsal scopula patch present; tegular apophysis distally widely scooped, basally narrowed to 1/2, pro- and retrolateral tip pointed not reaching margin of cymbium (Fig. 22E); palea about twice as long as wide; basoembolic apophysis triangular, about as long as broad; embolus, widely semicircular; terminal apophysis broad, deeply indented tips rounded (Fig. 47J).

Female (based on AM KS9756).

Total length 6.9.

Prosoma. Length 2.8, width 2.0; carapace and sternum colouration as male (Fig. 22C, D).

Eyes. Diameter of AME 0.12, ALE 0.14, PME 0.37, PLE 0.29.

Anterior eye row. Slightly procurved.

Chelicerae, labium, pedipalp coxae, legs and opisthosoma. Opisthosoma length 4.1, width 2.7; otherwise as male, but opisthosoma pattern more obscure (Fig. 22C, D).

Epigyne about as long as wide, with rectangular atrium (Fig. 22G); spermathecal heads huge, globular touching anteriorly, spermathecal stalks attached ventrally (Fig. 22H).

Life history and habitat preferences.

Habitat descriptions on collection labels with Artoria grahammilledgei sp. n. suggest the species to be a woodland and forest dweller in litter, i.e. 'dry sclerophyll forest’, ' Angophora costata woodland ridge top’, ' Eucalyptus botryoides - Allocasuarina torulosa open forest’ and 'litter & soil beneath Casuarina '.

Mature male Artoria grahammilledgei sp. n. have been found almost throughout the year, except November, February and March with two distinct activity periods in April and July. Mature females have been found in all months with a first peak from April to August, and a second in November. A female with eggsac was found in October/November and females with spiderlings in January, April, November and December. Therefore, the species appears largely autumn to winter mature, but with wide seasonal variation in relation to its reproductive behaviour.

Distribution.

In NSW, Artoria grahammilledgei sp. n. appears common east of the Great Dividing Range but has also been found along its west (Fig. 23). The species is also known from Queensland (V.W. Framenau, unpublished data).
