Moir, Melinda L. & Fletcher, Murray J., 2006, Two new species of Anabunda Emeljanov (Hemiptera: Fulgoromorpha: Achilidae) from Australia, Zootaxa 1328, pp. 39-50 : 41

Genus Anabunda Emeljanov

Anabunda Emeljanov, 2005: 30 .

Type species: Anabunda retortinervis Emeljanov, 2005 , by original designation.

Description: Colour. All species are predominantly green, fading to yellow in pinned specimens.

Body length. ɗ 5.9–10.9 mm, Ψ 6.7–13.4 mm

Head. Vertex rounded anteriorly and slightly concave, extending no more than one eye’s length in front of eyes. Vertex approximately half as wide as long. Frons approximately four times as long as wide with lateral and median carinae strongly elevated. Frontoclypeal suture not distinct, arching to form inverted U-shape with median point reaching lower margin of antennal scape.

Thorax. Pronotum rounded, projecting anteriorly to approximately anterior margin of eyes, bearing distinct median carina and two lateral carinae, these not reaching posterior margin. Mesonotum with three distinct longitudinal carinae; lateral carinae interrupted at approximately one-third length. Forewings with 16–20 apical cells and 1–4 rows of subapical cells. Vein CuA2 strongly recurved in all species except Anabunda minuta .

Male genitalia. Nomenclature follows Fennah (1945). Anal tube with terminal segment diamond-shaped and fringed with setae ( Figs. 4 e, 5e, 6e). Aedeagus with two appendages, generally tubular. Dorsal lobe of phallobase reduced to two small spines in all species except Anabunda minuta , where greatly expanded.

Distribution: Australia (NSW, Qld) ( Fig. 1 ).

Remarks: Anabunda can be distinguished from Rhinochloris by the latter’s having the head anteriorly sharply acute, usually forming a narrow horn. Species of Rhinochloris also have 3–4 spines on the hind tibia whereas Anabunda and Epiona have only one. Species of Anabunda and Epiona are generally more similar to each other but can be differentiated by the anterior margin of the pronotum, which is rounded in Anabunda and angulate in Epiona . The distal position of the single lateral hind-tibial spine places Anabunda in the tribe Achilini of the subfamily Achilinae (see Fletcher 2004).
