Genus Cebes Distant, 1916


Compiler and date details

4 April 2012 - Murray J. Fletcher

Introduction

This genus contains three mid brown, elegantly slender species distributed mainly in southeastern mainland Australia although Funkhouser (1951) lists Papua New Guinea for one of the species. Day (1999) indicated that the type species was set by "original designation". The only reference to a type species by Distant (1916) was in his description of the genus, where he noted that the posterior pronotal processes reached the "tegminal apices (at least, in type)". It is not clear to which of the two species he is referring to. The intimation is that he had only seen one of the species and this feature was apparent in that species at least. As one of the two species he included in the genus was described as new in that paper, Cebes godingi Distant, it is presumed that he had specimens of that species and it is to this that he appears to be referring as the "type". However, because of the doubt about his intention, the type species is here taken as having been set by the next available reviewer who was Goding (1939) who clearly stated that C. transiens (Walker) was the type species.

Diagnosis

Body elongate; tegmina about two and a half times as long as broad ("the third apical cell, very long and narrow, crossed by several transverse venules," Goding); pronotum centrally carinate, the anterior lateral processes triquetrous, conical, more or less directed outwardly and a little upwardly; posterior process tectiform, almost straight, slightly narrowed above scutellum, gradually acuminate to apex, curved downward, impinging on tegminal margin and reaching tegminal apices (at least, in type); ocelli above a line passing through the centre of the eyes, from which they are nearly as far apart as from each other (Distant 1916).

Day (1999) provided a comprehensive redescription of the genus.
