  Type data:

   Holotype BPBM No.1101 ♂ (coll.: i.1905, A. Koebele; holotype by monotypy), Mittagong, New South Wales.

Introduction

This species is very similar externally to Gaetulia chrysopoides (Walker) and there may well be specimens of this species misidentified in collections as G. chrysopoides. The only known locality where G. koebelei has been recorded is within the distribution of G. chrysopoides. The main difference between the two species is in the size and shape of the parameres and in the small process on the outer apical angle. Muir (1924) states that the two species also differ in colour and size although he does not give comparative details.

Diagnosis

Light brown, the carinae of head and thorax lighter. Tegmina hyaline, clear, veins dark brown, a light brown spot at apex of costal cell and another at apex of anal area of wings which are otherwise clear hyaline with brown veins. Width of vertex about twice the length in middle, apex slightly angularly produced, base widely angularly emarginate, a very faint carina down middle. Width of frons subequal to length in middle, base subequal to apex in width, slightly widest slightly before apex, sides straight to near apex then slightly curved, median longitudinal carina distinct; clypeus with median carina but no lateral carinae. Pronotum short, anterior margin produced into base of vertex, posterior margin widely angularly emarginate. Mesonotum with three carinae. Costal area with fourteen crossveins; apex of costal cell slightly enlarged. Sc + R fork and Cu fork about level, M fork slightly more distad, apical crossveins gradate, not forming a continuous line. The genitalia are very near to G. chrysopoides (Walker), but the genital styles are larger, wider, and have the outer margins straight; the outer apical angle is produced into a bifurcate process like a pick. Male — Length, 5.3 mm; tegmen 7.3 mm (Muir 1924).
