Everyone can do extensive ID research. You don't have to be a ranger! Haha. But really good to have one more species resolved in PN. Thousands more to go.

Finally got the species! This is a Hemithyrsocera vittata.

I went through all the 70 Hemithyrsocera species on cockroach.speciesfile.org and turns out only Hemithyrsocera vittata matches the distribution which includes both Thailand and Peninsular Malaysia where the "Gold-bordered Cockroach" occur. Seems like in quite a lot of website they have also correctly identify this species.

Hi everyone, this species is actually NOT a Hemithyrsocera histrio. I used to think this is a Hemithyrsocera histrio too but then I finally found the real Hemithyrsocera histrio. Here is my spotting for comparison:
https://www.projectnoah.org/spottings/28...

I notice that a lot of photographs in the Internet are indeed misidentified and are called Gold-bordered Cockroach. However, if you look closely at the specimen photos of this species, you can actually see the difference in the antennae - being feathery and having a white middle part. On the thorax you can also see an extra line in the middle.

Valid specimen photos are available on cockroach.speciesfile.org:

The distribution info also does not support it. When I first saw the distribution info of the Hemithyrsocera histrio which includes Borneo, I was surprised as there are a lot of photos of this "Gold-bordered Cockroach" on the Internet but none are actually from Borneo. From the available photos of the Gold-bordered Cockroach, it seems that it is distributed only from Thailand to Peninsular Malaysia which does not match the wider distribution of the real Hemithyrsocera histrio then.

Thank you for the ID suggestion, StefanPhalagorn and bayucca. I changed the scientific name to 'Hemithyrsocera histrio'.

Thoshimi, there is no doubt about the scientific correct and updated name of your nice cockroach. It is indeed Hemithyrsocera histrio with Gold-bordered Cockroach as common name. Hemithyrsocera lateralis is a junior synonym of Hemithyrsocera histrio, so not really wrong but outdated. For the correct completion of our and others database I suggest that you change the scientific name to Hemithyrsocera histrio, despite all the clowns in the circus of Project Noah, which spend a lot of their time to look for the correct ID for you and all other people on Project Noah.

You may add Hemithyrsocera lateralis being a junior synonym of Hemithyrsocera histrio in the description section.

Hemithyrsocera lateralis / Blatta lateralis Serville, 1838 is synonymous with Hemithyrsocera histrio (Burmeister, 1838).

It's Hemithyrsocera histrio (Burmeister, 1838), junior synonym: H. lateralis (Serville, 1838)
