Cockroach sp. ID? Too big for discoidalis, too light for cranifer.

These picture isn't the best, I know. I used a camera phone and these little fellas don't like to co-operate when it come to photographs.

My idea is cranifer. The roaches have got many colorvariations. Biggest patches or colour is darkest or lihgest. This is a stupid idea but may atropos.

Just read this on blaberus.com after your suggestion:

Blaberus atropus -- Coming 2006
$15 for 10
B. atropus are found throughout Central America and West Indies. This species ranges in size from 38-48mm. This is the most variably colored of all the blaberus. Most are darker in color similar to death heads, but about 20% will resemble fusca or discoids. This species is not related to the crosses of craniifer/fusca that are on the market. These roaches usually reach adulthood in 3-5 months and then will live another 12-24 months. Both males and females have wings, but this is a non-climbing\flying species

Myne are too big for astropus but having read that "crosses of craniifer/fusca that are on the market" bit I think that might be my answer. Cranifer, but not pure bloods. Thanks for the help.

The first picture almost looks like it could be a male B.dubia, but then again, I do have problems seeing the picture clearly.

Nah, I've kept dubai's before. The males and females have wings and aren't as golden-orange in colour.

Your help is much appreciated, thank you.

Those are the same hybrid as bug chick's below (they're actually direct relatives as all the 'hybrids' came from the same place). Sorry, the first pics threw me off.

I've had the oppurtunity to compare these to discoids and they were a fair bit bigger. I can only assume I've got some sort of cross breed.

If they were craniifer hybrids, I think you would be finding that the adults look really different from each other. Some would resemble craniifers and some would show heavy fusca influence. For example, here are two adults I pulled from the same colony. The darker one is a lot bigger and bulkier.

Okay, here's a few more dodgy photos, I dunno how much help they'll be. They vary in appearance but not so much in size. I guess it's possible that what I compared them to weren't discoids but some even smaller, similar species.

Your second batch of pics tells me I was wrong and it looks like you have the fusca/craniifer 'hybrid' 'cross'. The roaches you have originally came from Roachman in New York.
*Yes, sorry they should be a bit bigger than any discoid.

Thanks alot. That'd explain it then - not quite one thing or the other.
