  Type species:

   Macroceratogonia aurea Kirkaldy, 1906 by monotypy.

Introduction

This monotypic genus was described from the wet tropics of North Queensland and, subsequently, also recorded in New Caledonia when Evans (1974) synonymised the New Caledonian Petalocephala aurescens Distant with the Australian M. aurea. Its subfamilial affinities are currently uncertain.

Diagnosis

Pronotum, clavus, etc, finely punctured. Head slightly declivous; vertex at base less than ½ the width of the pronotum apically; lateral margins keeled, diverging somewhat sinuately, the vertex being thus wider at apex than at base and nearly as long as wide; apical margin slightly rounded; basal ¾ narrowly sulcate, anterior fourth transversely somewhat sinuately impressed; immediately below the impression and a little nearer to the middle line than to the lateral margins are the conspicuous ocelli. The crown is separated from the frons by a narrow, well marked, continuous channel. The antennae are situated almost at the antero-lateral angles, first segment small, rounded bulbous, second small cylindric, seta enormously long, much longer than the entire body. Frons narrow, and curves from the insertion of the antennae; clypeus elongate, parallel-sided; lorae curved exteriorly, not reaching the apical margin of the face, extending basally beyond the clypeus. Pronotum rounded anteriorly, lateral margins posteriorly divergent, posterolateral angles rounded, posterior margin subtruncate. Tegmina with 2 discoidal and 2 subapical cells, the exterior discoidal being undivided up to the apical cells. Appendix present. Wings with supernumerary cell (Kirkaldy 1906).
