Introduction

The identity of this species is still uncertain. The species was transferred to Chidaea Emeljanov by Löcker and Holzinger (2019) but, since it is based on a single female in a genus for which male genitalia is critical for identification, it may eventually prove to be conspecific with either C. crassa Löcker and Holzinger or C. bobadeenensis Löcker and Holzinger, both of which are also known from the Sydney region and share the presence of dark tubercles along the forewing veins with those species.

Frons 1.2 x longer than wide; position of maximum width distinctly dorsad of frontoclypeal suture; lateral carinae of frons in facial view convex, rectilinear apically. Frontoclypeal suture strongly semicircular, bent upwards, median part just reaching lower margin of antennal scape. Median carina of post- and anteclypeus well developed. Rostrum reaching hind coxae. Thorax: Hind margin of pronotum acutely angled. Mesonotum with weakly developed median and lateral carinae. Forewing 3.3 x longer than wide; concavity at costal border absent; costal margin with 20–22 tubercles; fork of ScP+RA and RP at same level or slightly basad of fork CuA1 and CuA2; tubercles of forewing dark, distinctly contrasted to paler coloured veins; ScP+RA apically bifid; RP trifid; additional subapical cell between branches of MP1 and MP2 absent; MP1+2 trifid; MP3+4 trifid; 12 apical cells; 6 subapical cells.
