New Eurycotis, Mahogany Pics, & Edrotes Larvae!

Here I get to showcase a new addition to the US hobby, one of two Eurycotis species collected from Golfito, Costa Rica. One species is small, red, and I suspect is E.biolleyi, and I've unfortunately not had much luck with my starter group of those... The species I'm showing off today is about twice as large, much darker, and I've actually had great success breeding them so far. I'm not sure what species they may be, for now I am referring to them as Eurycotis sp. "Golfito, Costa Rica - Dark" for now.

I have them set up in a moderately ventilated enclosure with a thin layer of coco fiber substrate, topped with eggcrates and paper towel rolls for hides. I am keeping them humid, at around 80-85F, and am feeding them dog food and fruits. 

Here are some pictures of an adult female:

They have proven to be both rather prolific, and not too aggressive or sensitive to crowding. They seem to be a good beginner Eurycotis species, and I hope they will catch on in the hobby!

I got some decent pictures of my Gromphadorhina portentosa "LLE Mahogany" recently, it's hard to capture their coloration accurately on my camera, but this is about as close as I can get!

Truly one of the most hardy hisser lines I've ever worked with, these are really slept on in the hobby!

I was recently sent some Edrotes ventricosus from Palm Desert, CA. These are a true psammophile, with very short lived adults (by Tenebrionid standards at least, a mere few months). Adults will seemingly only oviposit in very fine sand substrate, very few people have recorded getting eggs or larvae from theirs. I have succeeded in getting both now, and I'm hoping to rear said offspring to adulthood with any luck!

The breeding setup is a well ventilated enclosure with a couple inches of fine sand substrate, topped with some eggcrate pieces for the adults to hide under. I'm keeping a third of the substrate moist, the rest dry, and have them at around 80-85F°. I'm feeding them dog food and fish pellets.

So far the larvae seem to spend most of their time in the drier parts of the substrate, very much like Triorophus larvae (which are in the same tribe). That being said, they do seem to have some die offs if the enclosure dries out completely between waterings. They are growing rather fast, and don't seem terribly cannibalistic. Hopefully they'll be relatively easy to rear in a communal setting, as I've been doing with their close relatives Triorophus... 

Anyways, here are some pictures of the adults, and perhaps the only pictures of Edrotes larvae on the internet?

Adults

Larva

A very typical Pimeliinae build for the larvae, with that long and slender morphology reminiscent again of other Edrotini like Triorophus, and the relatively closely related Coniontini. Hopefully I can rear them to maturity successfully! 🤞 

Anyways, that does it for today, thanks for reading, hope everyone enjoyed, and I'll see y'all in the next post! 😉

A Proposal for the Use of Nothotaxa for Hybrid Hissers

Last year, Brandon Maines gifted me a group of hisser hybrids he had made between Gromphadorhina portentosa "LLE Mahogany" and Princisia vanwaerebeki "Tiger". The original cross was between a male Tiger and a female Mahogany, the resulting offspring have proven rather virile and have mostly adopted the coloration of their mother, which makes sense genetically.

However they have some distinct differences to the trained eye, mostly visible in the males. Said "Tiger Hog" males (Tiger Hog being the name Brandon has coined for this project), often have a shallow pronotum notch (a feature of Princisia), and much paler abdomens than normal Mahogany males do. Their thoracic coloration is different from Mahoganies as well, and the lateral margins of the thoracic pads of both males and females are more heavily curved than in portentosa (again more in line with Princisia morphology). Unfortunately other than the aforementioned thoracic pad differences, female "Tiger Hogs" look very very similar to pure "Mahogany" females. So I would not trust the average person to be able to reliably tell these apart from pure Mahoganies, which makes me very hesitant to ever part with any of these... at least, not without some more genetic foolery.

Now is perhaps the best time to share a dream of mine... a world in which designer hisser hybrids are as carefully bred and maintained as us enthusiasts do the pure species. Not just the random, mislabeled mutts we currently have circulating in the hobby (most of which are nade by accident), but purposely made hybrids, interspecies and intergeneric crosses, line bred for specific traits and labeled very meticulously and distinctly so as to avoid confusion and mixing with other stocks my accident. 

To further that end, among many other things we are gonna need some new naming conventions... I propose that we steal the horticulturist notion of nothospecies and nothogenera, made up species and genus names for specific hybrid mixes. The cacti hobbyists' method of nothogenera in particular is what I would like to adopt. 

A nothospecies is a name for an interspecies cross within a single genus. For example, the resulting offspring to come from crossing Gromphadorhina portentosa to G.oblongonata could be considered a nothospecies. A nothogenus would be an intergeneric cross, like a Gromphadorhina species to Princisia, or Princisia to Aeluropoda, etc..

These names are not completely without rules and guidelines for creation, there are in fact some conventions to keep in mind;

• It is generally recommended that for nothogenera, it be a combination of the two genera names involved in the cross, to make it more clear and helpful for understanding what genetics are at play.
• For naming nothogenera, when combining the genera names of the parents involved, the sexes of the parents used in the cross does matter, as the binomial name of the female in the cross gets first priority. So for example, if it was a male Princisia crossed to a female Gromphadorhina, you would name the resulting nothogenus "Gromphcisia". Whereas when crossing a male Gromphadorhina to a female Princisia, that resulting nothogenus would be named "Princorhina" or something similar.
• A hybrid name does not necessarily refer to a morphologically distinctive group, but applies to all progeny of the parents, no matter how much they vary. For example, the nothospecies name Gromphadorhina portengonota would be applied to all progeny from the cross Gromphadorhina portentosa × Gromphadorhina oblongonota, and those hybrids' resulting progeny, as well as from crosses of any of the progeny back to the parents (backcrossing). This can encompass a wide range of morphology and coloration differences between different line bred strains, all of which may have different strain names, but would still be considered the same nothospecies.
• Once a nothogenus or species has been initially created and named, anyone replicating said cross afterwards should adhere to said names, otherwise things would get way too confusing. We don't need a million different nothotaxa names for the same cross, even if they look a little different, you would just put a new strain name after the binomial one.
• When it comes to naming nothospecies, the rules are a little more lax. Obviously it should be latinized, unlike a simple strain name, and it's advised you attempt to incorporate the names of both parents, either their binomial names or the strain/locality names, again to make clearer what the cross is and to adequately describe the animal in question. 
• Random, accidentally created hisser mutts that can not be properly lineage traced should not be given nothotaxa names. Rather, just call them Gromphadorini sp. "Hybrid" or plain old "Hisser Mutts".
• Lastly, it should be noted that when it comes to making strain names, more research and attempts need to be made to verify whether hybrid lines can truly be line bred for specific traits, and so one should refrain from creating a new commercial strain name for specific line bred traits until said line breeding has proven true (backcrossing is a different story, since that will almost certainly affect genetics in a noticeable way). That being said, strain names even just for personal use when attempting to create new lines are still very important to use to help differentiate the different lines being created/isolated and to avoid accidental mixing, lest you accidentally mix some cultures up and undo generations of line breeding/crossing.

Hopefully that all made some sense, and explains where I'll be coming from with these naming conventions for now on. 😅

So, all that being said, we are going with the nothospecies and strain name Gromphcisia mahoganitigris "Tiger Hog" for this particular cross. Gromphcisia obviously being the combination between Gromphadorhina and Princisia, and mahoganitigris being a more fanciful combination of the scientific names of Swietenia mahagoni (West Indian Mahogany) and Panthera tigris (Tiger), obviously in reference to the strain names of each of the parent hissers. And then the strain name for this particular line, "Tiger Hog", obviously again a reference to the strain names "Mahogany" and "Tiger". 

Other named strains may eventually be isolated and line bred from this one or subsequent backcrosses, but they would all still be classified as Gromphcisia mahoganitigris, just with different strain names afterwards.

Anyways, without further ado, here are some pictures of these "Tiger Hogs", and a male G.portentosa "LLE Mahogany" for comparison:

"Tiger Hog" Males

Female "Tiger Hog"

"Tiger Hog" Pair

Tiger Hog male (Top) vs Mahogany male (Bottom)

Tiger Hog male (Bottom) vs Mahogany male (Top)

Pretty right? But still superficially very similar to pure Mahoganies... which is why I've taken a "Tiger Hog" female and paired her with a Tiger male, to introduce more Tiger genes into the line. She's already given birth, and with these extra Tiger genetics (and perhaps some line breeding), I will do my best to create a more refined "Super Tiger Hog" line that looks more like a half/half mix of these two species.

And, as a reminder, they would be named Gromphcisia mahoganitigris "Super Tiger Hog"; again the nothospecies name would not change because it is merely a backcross, but a new strain name can be used for a sufficiently different looking line.

Hopefully the nothotaxa convention I've outlined here (again, an already existing framework I've just stolen from horticulture hobbyists) will catch on, and hopefully we can enter an era of purposely made, fancy line bred hisser hybrids that are not only labeled correctly, but maintained in a manner consistent with that of pure hisser stocks. If done right, we could have more diversity in our hobby hissers, rather than less, but if rampant mislabeling and accidental crossing ensues, we could end up losing a lot of unique stocks, both pure stocks and line bred hybrid strains... so we have to be careful here, very careful.

Anyways, that does it for this post, thanks to anyone who read my rambling LOL. 😆 If anyone has any corrections, objections or suggestions, feel free to leave them in the comments below! Hope everyone enjoyed, and I'll see you all next post! 😉 

New Roaches & Some Roachy Updates!

My Blaberus sp. ""Pico Bonito, Honduras" have been absolutely booming lately, and I finally got some decent shots of an adult female that I wanted to show off here.

A nice sized, prolific Blaberus species, hardy too. I hope we get an accurate species ID/description for these one day.

---

I got some Panchlora cf. nivea "Little Manatee River, FL" from Tennyson a while back that have finally started breeding well for me. They are a nice, vivid green species, larger than the sp. "hobby" by quite a bit as well. So they may be true nivea, though they just as easily could be another misidentified species introduced there.

I have them in a moderately ventilated setup with a couple inches of coco fiber and coco coir chunks as the substrate. I keep them humid, at around 80-85F, and am feeding them dog food and fruit as the staple diet.

Here are some pictures of an adult female:

I really love the variety of Panchlora spp. we are getting into the hobby lately, would love to see some more of the fancy ones from Central/South America entering culture in the future.

---

I also got some Gromphadorhina portentosa "UCR" from Tennyson, a supposedly pure line that has at the very least been cultured for many years in a lab without any additional bloodlines being added to them. They are average sized for portentosa, and have rather average, if slightly dull coloration as well, thought they are a bit more variable than say, the "1972 Cleveland" stock.

I have them in a well ventilated setup with a thin layer of coco fiber substrate topped in eggcrates and bark hides. I am keeping a quarter of the setup humid, the rest dry, and am feeding them dog food and fruits as the staple diet. The colony sits at around 80-85F, and they are breeding like, well, roaches. So definitely one of the more prolific portentosa lines.

Here are some pics of an adult pair:

I would love to see some genetic analysis and comparison between these and other US hobby portentosa stocks, though that seems like wishful thinking for now...

---

I finally reacquired some Gyna centurio from Spencer Thornton in a trade, along with some other goodies I'll post about in the future. Been a while since I kept these, but needed to get some to complete my Gyna collection. 😂 Now I have them all muahahahah... 😈

Anyways, fairly simple setup for these, a moderately ventilated setup with an inch or so of coco coir substrate, kept on a 60/40 humidity gradient (erring on the humid side). Keeping them at around 75-80F, and am feeding them dog food and fruit as their staple diet.

Here are a few pictures of an adult female:

I had forgotten how pretty females of this species were... 😍

---

Lastly, my Gyna bisannulata continue to explode for me, and I decided to get some somewhat better pictures of an adult female as well, so here ya go.

A beautiful species, once nearly unattainable here in the US (and from what I hear, still quite uncommon overseas). Glad they are making a comeback in the hobby, they are such a pretty, ornately patterned species, and a hobby classic rare species.

Anyways, that does it for this post! Thanks for reading everybody, hope you enjoyed, and I'll see ya'll in the next post! 😉
