  1. Salut Cedric

    Oui, j'habite en France (proche de Genève) et je serais intéressé aux Blaberus colloseus, B. fusca et Pycenoscelus hemapterus (ça dépends un peu de ma femme ;) ). Bon, au moment c'est trop froid de penser à un échange... (Short translation for the other members: It's freeeezing cold here around!)



  2. Hi Zephyr

    You did it!

    Are these just "raw" genitalia or did you prepare them somehow? Roth discoloured them with a base (was it 10% sodium/potassium hydroxide?)...

    I don't have an opinion right now but I miss the whole rest of the genitalia. Where are these spikes and the fine membrane also used by Roth for the identification?

    You know, only one individual doesn't make the whole species; there are always variations not only in size, shape and colour of the "outer roach-surfaces". But on the other hand, two different genitalia from one strain might as well be a hint for hybridisation...



  3. Every G. grandidieri picture I ever saw looked absolutely the same like G. portentosa on my computer screen, just with that uniform dark brown. I do have some individuals beneath my G. portentosa looking pretty much the same *LOL*. Some say that here in Europe we have the G. portentosa color-morph 'G. grandidieri', the true G. grandidieri (maybe), and G. portentosa 'Black' (and presumably no one who can tell them apart).... it's a mess and that's why I ask for holotype photos and original descriptions with sketches.

    Or maybe someone skilled will paint me a 'comic' :D , but black&white please!

    Uppsss... and I fround the "True" G. grandidieri photos of wild living specimens on the blattodea species file site.

  4. Hi Orin

    That's the one photo I found :D .

    I know that P. vanwaerebeki is believed to be a local form of G. portentosa (quod es demonstrandum) but this is not my real issue. Besides, I know that no one could ever find a difference in male genitalia.

    I wonder whether there are such photos or sketches for the other Gromphadorhina sp. like G. oblongata and G. grandidieri maybe even in direct comparison with G. portentosa.



  5. Hi

    I wonder whether there are photos of the different Gromphadorhina sp. available online. I just could find the one of G. portentosa.

    And are there original descriptions available (I love these old ink drawings, they say more than photographs) or a listing of the differences as originally stated?

    I do have pretty much of a difficulty to see the species differences (color excluded!) even though I know them (some) in theory*.

    A rough sketch indicating exactly the important ones would help me too.

    * These bumps/dimples, the 'pinched together' pronotum, setae, horn angle etc. but I just can't see it clearly (either I need new glasses, I'm just stupid, or I only have G. portentosa or some kind of hybrids).



  6. Hi Mark

    The guy renaming the domino roach cultured here in Europe (User Lucihormetica if I remember correctly) does genitalia dissections in general. I don't know whether he did it in the particular case because the report is not yet freely available (therefore I didn't read it).

    You might send him a PM?



  7. Hi Ann & Rob

    Well, mine love more or less all roaches, including A. tesselata and G. portentosa (where you shouldn't feed the adult males!!!).

    I also have P. nivea but in my opinion the aren't worth it as adult Beardie food... too small sized ant too complex to breed.

    Greetings from Switzerland


  8. Hi

    Well, if the air inside is 90°F, the bottom will be even some degrees warmer and then your ootheca just dry out and if they would hatch, the young nymphs would die of thirst soon. (If you mean 90°C it would be much too hot and 90°R would be far too cold :lol: !)

    Keep them at 75-80°F (maximally 85°F).

    Shelfordella lateralis (syn. B. lateralis) is for two reasons one of the favorite feeder species: The don't climb glass and they already reproduce at room temperature. It's not a (sub-)tropical species like most other roaches kept in captivity and therefore don't need such high temps; constantly 90°F would even kill most of these.



  9. Do another search, Calypso isn't listed under that common name, though a few other like Paphiopedilum are. Your orchids are great though I've always been most interested in the various slippers. Nice photos, did you take them all yourself in the wild?

    Well... obviously Google doesn't know everything... Now I found the Pink Lady's Slipper (Cypripedium acaule) as possible species -> it's not only the roaches where scientific names are favorable :D !

    Paphiopedilum would also sound reasonable (when judging a small picture) if it would be native to the US (Wikipedia tells me they are not *lol*). I just found out that translating slipper into one of the possible German words gives Frauenschuh, the German expression for these kind of orchids.

    Besinds: The only "Frauenschuh" native to Switzerland is Cypripedium calceolus, a relatively rare species but if you happen to find one, you'll for sure find dozens nearby.

    Yes, that are photos I took on two trips here in Switzerland and the orchids are native ones.

    Neottia nidus-avis and especially Gymnadenia conopsea are pretty common in the mountains herearound.

  10. And a Coeloglossum sp., likely C. viride.

    One advantage of living in Switzerland seems to be that in terms of orchids we have the bigger biodiversity, such big, that I can't attach another (the last) photo I took of a C. viride with a different color :D .
