Type material: Deliochus humilis : Syntypes (1F, 1Juv): Australia, Queensland, Brisbane ( MG22569 ) ( ZMUH, examined). Araneus favorabilis : Holotype (1F): Australia, Queensland, Gordonvale , -17.081, 145.791 *, 9.ix.1912, W.J. Rainbow, holotype ( AM KS6518 , examined) GoogleMaps .

Diagnosis: Males can be distinguished from congeners by their shorter embolic serrations; D. zelivira has longer, more separated hooks and D. idoneus seems to lack them. Females have epigynal flaps directly posterior to the copulatory opening rather than lateral or posterior-lateral ( Figs 31D, 32E–G). Both males and females lack the dark marking where the pars cephalica and pars thoracica meet.

Abdomen 1.80 long, 1.34 wide, 1.30

high, light brown with two longitudinal yellowish white stripes of guanocytes; venter light brown. Palp ( Figs 31E–I, 33E–I) typical for Deliochus , with short tibiae (<1/2 length of cymbium) and numerous short embolic barbs-like serration on both sclerotized embolic shaft and sperm duct distally. Variation: Females’ (N = 4) total length 6.96–7.59; carapace length 2.56–3.62, width 1.81–2.41, height 0.64–1.26; abdomen length 3.42–4.49, width 2.64– 3.81, height 2.78–3.91; sternum length 1.23–1.69, width 1.01–1.32. Males’ (N = 3) total length 1.29–3.05; carapace length 1.19–1.61, width 0.99–1.09, height 0.44–0.58; abdomen length 1.30–1.80, width 0.99–1.34, height 0.92–1.30; sternum length 0.71–1.16, width 0.66–0.95.

Natural history: Half and full eunuchs and copulatory plugs formed from broken emboli are common. Cohabitation of males and females in web-adjacent leaf retreat observed.
