Oliarus talunia Kirkaldy nom. dub.

( Figs 13A–D)

Oliarus talunia Kirkaldy, 1906: 398 .

Type material Syntype, ♀ (examined), AUSTRALIA, Qld: Cairns , viii.1904 ( BPBM) .

Colour

Body including legs pale yellow except for light brown mesonotum; forewing hyaline white with brown marks along crossveins and apices of apical veins; veins white, tubercles mid to dark brown (contrasting with veins).

Morphology

Body length: ♀ 5.3 mm.

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

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

Male genitalia: Unknown (only known specimen is a female).

Remarks

The narrow vertex and the chaetotaxy of the hind leg (2 lateral spines on the tibia, 7 apical teeth on the 1 st tarsomere, and 5 apical teeth on the 2 nd tarsomere) verify the placement within the genus Oliarus sensu Emeljanov. The pale yellow colour except for a light brown mesonotum, mid brown tubercles, and brown marks along crossveins and apices of apical veins, together discriminate this specimen from all other Australian Pentastirini . Whether this represents the typical coloration of this species or is an artefact cannot be determined because only one specimen is currently available. For this reason and because of the absence of male genitalia, O. talunia is regarded as a nomen dubium.
