A relatively small Temognatha with background colour varying from red to orange or yellow.
The type locality of this species is Gawler (about. 50 km N of Adelaide). The same author also described Stigmodera unicincta Saunders 1872, which is a synonym based on a Type specimen from Adelaide of the same species. The species is widely distributed but seldom collected.
| Legend | records | count of breeding adults, pupae and larvae |
| sites | count of major sites (unique 10 km grid cells +/- some distinct approximate localities) |
| adult | live = extracted alive; dead = extracted dead as intact or fragmentary remains; ex billet = reared and emerged from stored sections of host; ex pupa = reared from sampled pupa |
| pupa | extracted pupa; pupa ex larva = reared pupa from larva |
| larva | extracted larva (any stage including prepupa) |
| gall (only) | hatched or unhatched gall identified by form and position rather than contents |

A.M.P. Stolarski discovered the breeding records for this species in the upper South-Eastern region, with a reared adult and dead remains obtained from the stems of Slaty Oak-bushes (Allocasuarina muelleriana).
An amazing record from suburban Adelaide was reported by Asimakis Patitsas on iNaturalist who discovered a recently emerged individual on the trunk of a Sheoak (see images above) with a nearby exit hole bearing fresh frass. The tree was a planted Drooping Sheoak (Allocasuarina verticillata) approximately 5 years old (Patitsas, 2020, pers. comm.).
In September 2023 I discovered a yellow larva which I tentatively identified as this species in a small side branch of Drooping Sheoak Allocasuarina verticillata in the Adelaide foothills, and its identity was confirmed in May 2024 by its DNA barcode (mitochondrial CO1 sequence).
