( Figures 1A–D View Figure 1 , 2A–G View Figure 2 )

Description

Body large, distinctly elongate and slender, length (from apex of vertex to tip of forewings): male (n = 9), 6.5–6.9 mm; female (n = 3), 8.7–9.0 mm.

General colour reddish brown, vertex, pronotum and scutellum covered with fuscous punctures, anterior margin of tylus and median carina of pronotum black, scutellum with median line suffused with yellowish white; head beneath reddish brown, frons suffused with dark brown, antennal sockets, scape and pedicel reddish brown; rostrum with apical segment dark brown; thorax beneath pale yellowish with pleurae partly brownish; legs pale yellowish, claws brownish, tips of spines on hind tibiae and tarsi black; forewings ( Figure 1A–D View Figure 1 ) reddish brown, the extreme costal area, a small costal marking beyond middle, a relatively large subtriangular costal marking at subapical one-third, whitish; some indistinct spots scattered on clavus and corium, the subapical area of calvus and the cellar areas at apical one-fifth very pale whitish; hindwings pale brown, covered with brown hairs, veins brown; abdomen fuscous with segmental margins ochraceous.

External structure as in the generic description. Head ( Figures 1A,C View Figure 1 , 2B View Figure 2 ) maximum width (including eyes) 3.7–4.0 times as long as median length. Vertex ( Figures 1A,C View Figure 1 , 2B View Figure 2 ) with a distinct median carina, median length 0.4–0.5 times as long as length of pronotum medially. Frons ( Figures 1B,D View Figure 1 , 2A View Figure 2 ) in the males very strongly compressed and depressed laterally, thin in lateral view, median longitudinal carina distinct. Pronotum ( Figures 1A,C View Figure 1 , 2B View Figure 2 ) with median longitudinal carina reaching to posterior margin of pronotum, median length 0.5–0.6 times as long as maximum width.

Male genitalia with pygofer ( Figure 2C View Figure 2 ) high, wider ventrally than dorsally, anterior and posterior margins nearly straight and quadrate in lateral view. Basal anal processes ( Figure 2C,E View Figure 2 ) elongate, slender and curved, inner margins without fine spines. Subgenital plates ( Figure 2C,D View Figure 2 ) relatively elongate, apically parabola-like. Genital styles ( Figure 2C,D,F,G View Figure 2 ) relatively elongate and slender, broad mesially, narrowed to apex over distal one-third, apically bidentate. Aedeagal shaft ( Figure 2C,G View Figure 2 ) short and broad, straight, with a gibba-like process on anterior edge subapically in lateral view, the process with its semicircular outer edge covered with fine spines; gonopore dorsal.

Material examined

Holotype. Male, [ Australia, Queensland] 6.4 km west of Paluma, Qld , 900 m, 25 April 1969 (I.F.B. Common & M.S. Upton) ( ANIC).

Paratypes. [ Australia, Queensland] six males, three females, same data as holotype ( ANIC) ; two males, Mt Edith, 29 km northeast of Atherton , Q., 1020 m above sea level, 18 March 1964 (I.F.B. Common and M.S. Upton) ( ANIC) .

Etymology

This new species is named for the presence of a gibba-like process on the anterior edge of the aedeagal shaft subapically in lateral view ( Figures 2E–G View Figure 2 ).

Distribution

Australia (Queensland).

Remarks

This is the largest species currently known in the genus. It can be easily distinguished from other known species in the genus by its largest size, more elongate and slen- der body ( Figure 1A–D View Figure 1 ) and the male genital structure, especially the aedeagal shaft with a gibba-like process on anterior edge subapically in lateral view ( Figure 2C,G View Figure 2 ). Externally this species is similar to A. leiala Kirkaldy , but differs from the latter in its vertex, pronotum and mesonotum covered with fuscous punctures, pronotum with the median longitudinal carina black, and the scutellum with median line suffused with yellowish white, in addition to the differences in the body size and the male genital characters mentioned above.
