Introduction

This tribe was revised by Löcker et al. 2006 and the Australian fauna was increased from 7 to 27 genera and from 9 to 60 species. It is distributed primarily in Australia with an additional two species in New Caledonia.

Diagnosis

Gelastocephalini are characterised by the following combination of characters: absence of a median ocellus; a single distinct transverse carina between vertex and clypeus; hind tibia with six (rarely five or seven) apical teeth separated into two groups by a gap (diastema); the outermost spine of the outer group being larger than the second and third spine; spines of the inner group short, not levelled basally with outer group, but still extending as far as the first spine of the outer group; 2nd hind tarsomere triangularly shaped, apical teeth (except for the external ones) reduced, bearing platellae; absence of wax plates in ovipositor; male pygofer with triangularly shaped (angle >60°) ventromedian process, sometimes truncated apically. The short male anal style, entirely concealed by the edge of the 11th segment is seen as a synapomorphy for the tribe Gelastocephalini. (Löcker et al. 2006)
