Any idea as to id?

99% sure it's Rhyparobia.

I'm not familiar with any species in that genus other than maderae, sp. "Malaysia", and grandis, but although it doesn't appear to be any of those I wouldn't rule out maderae. An excellent find, however! Unfortunately it looks like a male (if those are two small segments at the end of the underside of the abdomen) but finding a female shouldn't be too difficult since you know they're in the area! :)

Oh what I'd give to have exotic roaches flying into my house...

I would presume that both sexes occupy the same environment. To the extent of my knowledge the females of all members of the genus are also fully winged and depending on whether or not they're gravid they will possibly also be able to fly. The nymphs (if this is indeed maderae) will be a gray-ish color and should be present near the adults.

Hi, unfortunately we do not have a local agriculture station with knowledge about insects. Around here(to most people) a beetle is a beetle, and a cockroach is a cockroach. Our agricultural centres aren't much better. I will see if I can track down a specialist in our native species, but responses are usually slow. That is a large part of why I utilize the forums. Thank you for the suggestion, though

I agree, wholeheartedly! One more specimen flew into my lounge tonight, and it is somewhere in here. I just hope that I can find it!

He is currently sharing a naturalistic enclosure with an Oxyhaloa deusta specimen, and some unidentified roaches.

I'm hoping very hard that I'll find a female.

I'm very sorry that I haven't gotten around to taking photos yet. Things suddenly became very busy around here. But, I am quite certain that I do have a pair. The one is lighter than the other, and earlier the one was stroking the other with its antennae. Possibly, I think, courting behavior. I am also happy to report that my Oxyhaloa deusta have begun breeding.

Thank you, truth be told, i just haven't managed to keep the cockroaches upside down long enough so I can take pictures, and they don't climb the glass. Any suggestions for getting good pictures of their undersides? oh, and if I place them in the fridge for a few minutes so they fall asleep long enough for me to take photos of their undersides will that have any negative side effects? Thank you so much for your interest, and for helping me so much.

When I need picture of the underside, I use to keep the roach between two fingers in one hand, and to take a picture with the other hand. The method with the fridge can work, but some species don't support it, and most females will abort their ootheca by this way, it's why I don't use it.

No problem for the help, I'm happy to be useful, cockroaches are so amazing, it's wonderful to talk with other enthusiasts!

Thank you for the ideas, and tips. Sadly, :( I lost one of these cockroaches, and I had to release the other one because it wasn't eating. I have, however, found another very interesting species. I will post photos soon. :lol:
