Type material

Holotype, ♂, AUSTRALIA, WA: Kununurra , 7.xii.1983 (A. Postle) ( ASCU HE 005978) , Paratypes, AUSTRALIA, WA: 1 ♂, Argyle Diamond Mine , ca. 110 km SSW Kununurra, 6.xii.1983 (A. Postle) ( WAMP), 1 ♂, same data, 9.v.1985 (A. Postle) .

Etymology

The Greek term ‘akantha’ means ‘thorn’. Named after the spinelike processes on the pygophore.

Colour

Body dark brown, carinae and pronotum paler; legs light brown; forewing hyaline colourless with indistinct brown marks along crossveins, veins light brown apically darker, tubercles slightly darker than veins, pterostigma light to mid brown; abdominal sternites light to mid brown.

Morphology

Body length: ♂ 4.0– 4.6 mm.

Head: Vertex (total length) 1.9–2.2 times longer than wide; basal emargination obtusely angled or rectangular. Postclypeus with well­developed median carina. Rostrum not reaching hind coxae.

Thorax: Hind margin of pronotum obtusely angled. Mesonotum with well­developed carinae. Forewing 3.4–4.1 times longer than wide; costa without tubercles; 8 apical cells.

Male genitalia: Anal tube as in Figs 33A–C; pygophore dorsolaterally on each side with long, outwardly curving, spinelike process as in Fig. 32N, genital styles with large spinelike process directed dorsad as in Figs 32Q–R, 33D. Aedeagus ( Figs 32N–P): Phallotheca with a long, strongly curved spine (a) arising ventrally; a long, strongly curved spine (b) arising dorsally; and a large sclerotised flap ventrally. Flagellum membranous, unarmed, very small.

Remarks

This species can be distinguished from all other Australian Pentastirini by the presence of a long dorsolateral, outwardly curving, spinelike process on each side of the pygophore (see Fig. 32N).
