Is it just me ....or does that have a good resemblense to a C. Gracilis. The subacular spine seems to be in most(if not all) Tityus spp., but not in all Centruroides spp. I wonder if it got its name from being in the U. S. and therefore classified as though. I think they might be very close in spp. types.

Mat,

I don't think a taxonomic error of that magnitude would be missed this long. While we tend to use some very crude methods of identification around here (proportions, colouration, major structures), taxonomists use minute detail to make these destinctions. Now some are even using genetic data to put together taxonomic relationships, though this hasn't been done that extensively with arachnids.

Cheers,
Dave

Hi Mat,

Yes, it does look alot like C. gracilis.

Cheers,

Just for the record, these pictures are copyrighted. I don't know what legally has to be done to post these, though it would be safer to just post a link. I'm not trying to give anyone a hard time, I just don't want arachnopets to get in trouble. I'm fairly sure that Jan does not have the rights to those images, so you'd have to ask the people who took them.

well thats the thing , all the pics of C . gracilis i`ve seen have much darker legs then that one in the scorp files, but others on that site resemble mine and that of this Tityus spp. . I`m no expert but i know there can be color morphs ....so whats the real differences ??

Hi Matt,

According to Scorpions of Medical Importance by Hugh L. Keegan, Tityus is similar in size, habits, and general appearance to Centruroides. However, there are no "supernumerary granules flanking the oblique, median rows of granules on the movable finger of the pedipalp." Tityus also has no less than 14 oblique rows of median granules, while Centruroides has no more than 9.

It also says that of Tityus, those that are dangerously venomous are Tityus serrulatus, Tityus bahiensis, Tityus trinitatis, and Tityus trivittatus. Also, subspecies T. t. charreyroni. He also mentions Tityus cambridgei.

Hope this helps you.

Best wishes,

Paul

Sorry Chis,

I really didnt know this, i´m not used to the terms of "Copyrighting"...
And I didnt pay attention on the detail...
Actually, I don´t know about this web rules...
sorry again...

[Reitz]

I wasn't trying to be mean. Honestly, don't worry about it. I just don't want arachnopets to get in trouble. It's not your fault, I just want to make sure that the moderators know what to do with them.

I'm actually waiting on a reply from the webmaster of TSF to see what he would like to be done.

Thanks,

Hey Thiago,

Basically "Copyrighting" has to do with ownership of a photo. It's bad netiquette as well as illegal to save a photo that you don't hold the copyright to and then post it somewhere else. As you can see, the pictures have been removed. Sorry about that.

Scott

 

[ThiagoMassa]

All right!

Thanks Scott, helped a lot! I´ll try to be more carefull.
Well, at least we have the link!


Back to my T. serrulatus, what should I put in its tank?
By now, his tank is like this...
Any suggestions?

Tityus serrulatus

Hi,

Here's some info for you on Tityus serrulatus, described by Lutz and Mello-Campos in 1922, from Scorpions of Medical Importance by Hugh L. Keegan:

"This species, generally considered to be the most dangerous scorpion in Brazil, occurs only in that country, where, according to Bucherl (1971), it is found in the states of Sergipe, Bahia, Minas Gerais, Espirito Santo, Rio de Janeiro, Goias and Sao Paulo.

In life, the cephalothorax and all but the last segment of the preabdomen vary in color from yellow to blackish brown with some dark marking on each segment. The last abdominal segment, the postabdomen and the appendages are pale yellow, except that the fingers of the pedipalp and the telson are reddish brown. The aculeus may be almost black. An important taxonomic characteristic is that the granules of the dorsal median keel on the third and fourth segments of the postabdomen are distinctly enlarged to form a serrated appearance when viewed laterally.

The medical importance of T. serrulatus stems from the toxicity of its venom plus its habits, which are similar to those of Centruroides sculputuratus in the United States. As a "domestic" species it is a frequent cause of scorpion sting. In some parts of Brazil it is exceedingly common. Bucherl (1971) wrote that during the period of 1949 to 1963 about 138,000 specimens of T. serrulatus were captured in four cities of Brazil and sent to the Instituto Butantan for venom research and antivenin production. In the areas where the species is found, various insecticides have been tested in control programs. Souza et al (1954) found lindane to be effective in scorpion control when it was used as a residual spray in and around buildings. Bucherl (1971) also found lindane to be effective but noted that contact with this insecticde excited the scorpions, making them more active and increasing the possibility of envenomation. Because of this, in later years, a 5% DDT emulsion was used in control programs.

Tityus serrulatus is unique in that, apparently, reproduction is entirely by parthinogenesis. A male of the species has never been found. Parthenogenetic birth in the laboratory was first described by Matthiesen (1962) and again by San Martin and Gambardella (1966). Bucherl (1971) found only females among over 60,000 specimens received at his laboratory. In addition, he found only ovaries in about 8,000 dissected specimens.

Adults of this species may attain a length of about 70 mm. Specimens supplied by Dr. Wolfgang Bucherl, were from the colony maintained at the venomous animals laboratory at the Instituto Butantan, Sao Paulo, Brazil."


Cheers,

Paul

(Not what you were asking, but I figured this information would be useful to you in identification/knowledge and for others on the forum)

 

[ThiagoMassa]

Uow!

Thats a lot of info there, thanks a lot Paul!

I live in the state of Distrito Federal, but its right in the midlle of the state of Goias. There was a time in my city when this scorp was a plague and that control mentioned on the text was made here. In a part of the city named Cruzeiro we had the most part of the scorps. Many people moved from their houses (apartments) couse of that. (Just adding local info!)

Now I know my scorp is the most dangerous here! hehehe :}


->:? I´m a beginner in scorps, but i´m really appreciating having one, how can I collect them wild, I mean, i don´t have that UV light and don´t now how expensive it is. What places should I look? How to collect them, do I have to use pincers (clips)?

->Where I find some caresheets of the T. serrulatus? And about the tank, I was think in put some substrate, wich sand (white, yellow, brown, red, black) is the best? Do I have to bake it or boil?

Thanks
Massa

 

[ThiagoMassa]

forgot...

about the water, i put a thin layer on a "cover, case"(don´t know the word, but you can see on the picture), it´s something about 5mm deep, and i´m sure that if the scorp fall into this it can easily get out. May I keep it there or replace it with cotton?

 

[ThiagoMassa]

Today my scorp ate a big fat cricket, almost its size! And I am very proud! Hhahahahahahahhahahahahhaha
In the pic we just see 2/3 of the cricket...
The criket was eaten upside down, that´s not a picture defect.
sorry about this but I´m really not used to see that kind of thing and I became excited! hahahahha

 

[ThiagoMassa]

:?
Is there any problem about to put pictures of mine on the page, and, is there any problem about to put so many pictures as I did?
If there is a number, how many pics may I put in the page? It´s just because I don´t write in english very well, and I don´t know the names of many things, so it´s more practical for me showing the pictures of my doubts, like the species, the tank...

I want to show a better pic of the tank to show the proportion of the scorp and the space it has, does it needs more space?


Thanks!
Massa

You can post as many of your picutures as you'd like.

As for collecting scorpions, be very careful. The ones in your area are very dangerous. You should probably get some tongs or 'pincers' to collect them, because you don't want to risk getting stung. In terms of where to look, the black light may no be necessary. You could probably just look around building overhangs, behind bark on trees and under rocks. They're nocturnal, but since the population is so high in your area you've still got a good chance of finding some during the day.

Your water source looks good. You don't want cotton in there because it is prone to bacteria.

Substrate should probably be potting soil, though others would know better than I. I *think* they need temps and humidity around 80, though get a second opinion on this.

The tank size looks fine.

Good luck,
Chris
