New Therea species could be coming to US hobby

I've been hearing rumors lately that a new species of Therea is coming to the US hobby. It is rumored to be Therea bernhardti, and is apparently already (rarely) available in Europe. There's also this image that I have seen (I didn't find the image, that credit goes to HisserDude!) of a mystery Therea sp: http://www.karaczany...um.pl/therea-sp

I've also seen a few dealers list "black underwing domino cockroaches" as T. bernhardti. What do you guys think of these rumors? Is the USA getting a new roach, or is this all wishful thinking and hot air?

The species in the link is not T.bernhardti, it is an unidentified species. The species pictured has a squiggly line in between two dots, which does not match any other species currently kept. Hopefully they make their way into the US hobby!

T.bernhardti seems to be identical to T.petiveriana except for the black underwings. All the T.petiveriana in the hobby may actually be T.bernhardti. Here is a link from the same site for T.bernhardti: http://www.karaczany.terrarium.pl/therea-bernhardti

Ok, thanks for clearing that up. I thought it was strange that there was that mysterious link you posted, and there were the "black underwing" dominoes. If everything we thought was T. peterivana is actually T. bernhardti, then what does the true T. peterivana look like?

I don't know, maybe similar to T.bernhardti but with clear wings? Someone should take a look at their "T.petiveriana" and see if they have clear or black underwings. I would, but none of mine are adults yet!

By the way if anyone was interested, here is the description for Therea bernhardti: http://www.schaben-s...cont=bernhardti It even says at the bottom that T.petiveriana is probably not in culture.

I'm curious about who's making this rumor. As far as I know Jorg (person who originally had this species) lost his culture, and it seemed that other people who've received them didn't do well. Did some random guy secretly kept this species hidden from other hobbyist and has just began releasing them back into the hobby?

Are you talking about T.bernhardti, or the unidentified species in the first link? Pannaking22 said on Arachnoboards that he had friends who said they may know of a fourth species that may be in culture, but that it was just rumblings.

I personally think that all the Therea petiveriana in the hobby are in fact Therea bernhardti, and now that people are labeling them as such, confusion has arisen for those unaware of the taxonomic changes and they think we have gained a fourth species when in reality we still only have three. There is that one unidentified species in the first link but that seems to be kept only by that one person in Europe, not anyone in the US.

We should start an unofficial little study here. It wouldn't be very scientific, and I doubt any serious entomologists (other than myself lol) would take any notice of this, but we could still learn something. If you own any, check the underwings of your dominoes. If they are black, you can say you have T. bernhardti. If the underwings are transparent, or another color, you can say you have T. peterivana.That way we can see which people/ dealers have the true dominoes, and which have the black underwing dominoes.

Yes, anyone who has adult domino roaches, please check the underwings! We need to know! I need to know! :lol:

Just because the spots are a little different doesn't make it a different type of cow (not necessarily anyway).
 
Here's a new one:

Therea still petiveriana

Aww, that sucks. Hopefully it will show up again. :(

I think we all have petiveriana. http://cockroach.speciesfile.org/Common/basic/ShowImage.aspx?TaxonNameID=1178148&ImageID=205983

Is that one of your specimens? If it's not, then we could all still have T.bernhardti. Someone needs to look at the underwings!

Yes, I saw that. I don't think that the claim of it being T. peterivana is correct. If anything it is a morph of T. olegrandjeani.

It is a color form of T. petiveriana and its offspring can look normal. Just like yellow lurida and black hissers, an unusual color form within a colony does not become a new species. I did not think anyone would be confused by the name still petiveriana.If you look at the CSF photo link posted earlier from a specimen holding you will see T. petiveriana have black underwings so you're placing a lot of stock in the wrong feature.

I think Peter would be happy to see you named a roach after him.
