I have been looking at this sighting, its unlike any other sightings on CNM. At first I was thinking Periplaneta americana but on looking through Rentz I think it may be a Neotemnopteryx sp. (N.bifurcata or N.fulva). (A Guide to Cockroaches of Australia p231-232. If anyone is willing I would appreciate some feedback on this possible ID. @Illilanga @RogerF @youning @KimberiRP

I don't know. Maybe @Tapirlord could clarify that. It is reported as 25-50mm, a large range.

Thanks for the size update Tapirlord. That's a reasonably large cockroach. A. periplaneta can be 30-50mm. Rentz says of Neotemnopteryx that they are "larger than many other blattellines" which is a bit vague, but I could possibly infer this means over 25 or 30mm?
The more I look at this sighting, and of examples of American cockroach, and of Neotemnopteryx on the internet and in Rentz, the more I think that this specimen doesn't show typical pronotum patterning of A.periplaneta, but does show subtle markings common in Neotemnopteryx, especially some specimens of N.fulva.
I also find it unlikely (but not impossible) that A.periplaneta, which loves basements, sewers and kitchens would be found in the middle of Bluetts block, it is not a cold loving species. Also, there are no reports of this species on ala, although local pest companies do list them as one of the possible pest cockroach species in Canberra. Nevertheless, this is a much more likely habitat for Neotemnopteryx, and the pronotum markings makes me think it is this Genus.
Any thoughts? @RogerF @illilanga @Youning

When new species are proposed, I think we should check/confirm with Dave Rentz and Youning Su

@RogerF could you contact them?
The more I compare this sighting with the species in question the more convinced I am, but it would be good to have an expert opinion to confirm.
A sighting on North Coast Nature Map I think is also Neotemnopteryx Neotemnopteryx sp. (genus) (Cockroach)
