Oliarus alexanor Kirkaldy nom. dub.

( Figs 10E–H)

Oliarus alexanor Kirkaldy, 1906: 399 .

Type material

Syntype, ♂ or ♀ (abdomen missing) (examined), AUSTRALIA, Qld : Cairns, viii.1904 ( BPBM) .

Colour

Body mid brown to dark brown, carinae paler; legs light brown; forewing hyaline colourless with brown marks along crossveins, veins light brown, tubercles and pterostigma mid brown.

Morphology Body length: 5.0 mm (gender unknown since abdomen of specimen is missing).

Head: Vertex (total length) 1.8 times longer than wide; basal emargination obtusely angled to rectangular. Postclypeus with well­developed median carina.

Thorax: Hind margin of pronotum obtusely angled. Mesonotum with evanescent median carina and well­developed sublateral and lateral carinae. Forewing 3.3 times longer than wide; costa without tubercles; 8 apical cells.

Male genitalia: Unknown (only known specimen is lacking its abdomen).

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 . Because of the absence of male specimens this species cannot be reliably identified. For this reason O. alexanor is regarded as a nomen dubium.
