Wolfie Posted May 15, 2013 Share Posted May 15, 2013 I hope this is on the right board. I got these guys a couple of months ago under the name 'Madagascar Hissing Cockroach' which, I assumed, meant I was getting G. portentosa, but I've been looking at other people's hissers and I'm not sure, they look a different colour to the other G. portentosa I see, which are more yellowish-orange and black, whereas these are more reddish-brown and black, and really, rather beautiful creatures. Are they a different colour morph? A different species? Some kind of hybrid? Anyway, I took a photo to help, male is at the bottom, female at the top.

happy1892 Posted May 15, 2013 Share Posted May 15, 2013 I think Gromphadorhina oblongonata are red like that. Look at the pictures here. http://www.roachforum.com/index.php?showtopic=749 Quote Link to comment Share on other sites More sharing options...
wodesorel Posted May 15, 2013 Share Posted May 15, 2013 Hissers can vary a bit in color. Species are differentiated by the horns: http://www.roachforu...?showtopic=4356 Edit: NM.... There's a link to that photo in the topic happy provided. Quote Link to comment Share on other sites More sharing options...
Nicolas Rousseaux Posted May 16, 2013 Share Posted May 16, 2013 hi they LOOK like Gromphadorhina oblongonata, but I'm not sure they are. The only way to know their exact specie is to let a specialist look at the male pronotum... As wodesorel said, a same specie can show loads of diferent colours!

Wolfie Posted May 16, 2013 Author Share Posted May 16, 2013 Thank you for your help guys, I understand it's impossible to be certain. Whatever they are, they are gorgeous, I'm hoping if they breed the nymphs end up the same reddish colour, it's quite spectacular. Quote Link to comment Share on other sites More sharing options...
happy1892 Posted May 16, 2013 Share Posted May 16, 2013 Wolfie what do yours look like the most? Do yours look more like G. portentosa or G. oblongata from the pictures of the pronotum? Quote Link to comment Share on other sites More sharing options...
Wolfie Posted May 17, 2013 Author Share Posted May 17, 2013 It's hard to say for certain, but looking at my male's pronotum, the front edge, where you can see there's a kind of up-turn where the head is, the curve of that seems narrower and more pronounced in my male than that of G. portentosa in the images, with a lot more of those dimple-like bumps, and it just generally looks more 'streamlined' in shape. So if I was pressured into going for any of them, I'd say G. oblongata is the one he resembles the most. Quote Link to comment Share on other sites More sharing options...
