Description: Colour. Frons, vertex, pronotum, mesonotum, legs green. Spines on legs black. Eyes black fading to brown in older specimens. Forewings green, with four small dark brown spots along medial vein, large brown distorted spot midway along clavus ( Fig. 2 c), apical cells with dark brown along posterior edge. Hindwings smoky white

Body length. ɗ 5.9–7.0 mm, Ψ 6.7–7.5 mm

Head. Vertex projecting approximately half eye length beyond eyes, and with distinct median longitudinal carina. Frons widest at midpoint with dorsal margin approximately two-thirds width of widest point. Frontoclypeal suture obscure.

Thorax. Pronotum extending slightly beyond anterior margin of eyes, hind margin angulately emarginate. Forewings with 14–16 apical cells, one row of subapical cells, and pterostigma of reticulate veins two rows deep, with 4–5 cells in 2nd row. Hind-tibial apical spines in two distinct rows, with 10 and 7 spines ( Fig. 3 c).

Male genitalia. Anal tube relatively uniform in width throughout ( Figs. 6 d, e). Medioventral pygofer process shaped into three peaks, median longest ( Fig. 6 b). Parameres with ventral surface smooth ( Fig. 6 b), dorsal surface twisted and with disc-like flange lined with marginal setae ( Fig. 6 a). Aedeagal appendages expanded at posteriorly, and dorsoventrally flattened ( Figs 6 a, c). Dorsal lobe of phallobase greatly expanded, extending almost to apices of appendages and enveloping aedeagal appendages to meet ventral lobe ( Figs 6 a, c). Ventral lobe of phallobase high, enveloping anterior half of appendages ( Figs 6 a, c). Lateral lobes absent.

Remarks: The male genitalia are very different from those of other species within the genus, especially in the length of the dorsal lobe of the phallobase, lack of lateral lobes, and the shape of the aedeagal appendages. Anabunda minuta appears restricted to coastal regions in far northern New South Wales and southern Queensland, within dune systems, rainforest, and wetter open forests ( Fig. 1 ).

Etymology: Named after the species’ smaller size than all other described Achilini species from Australia.

Common name: Delicate green fungus bug
