    Taxonomic Updates, Information and ID Keys For Scorpions

    This sticky will be devoted to the posting of updates and changes to taxomic nomenclature and identification of scorpions. The reason I am doing this it to make an attempt to keep all this information in one easy-to-find place.

    Please keep all comments and discussion strictly to the taxonomic posts. I will attempt to moderate this thread quite strictly to keep the fluff to a bare minimum and will delete all posts not directly relevant to the information that will end up here. I ask everyone to do their part and not post OT in this thread.

    To reiterate. This is not a thread for posting keeping conditions, enclosure information or behavioral information. This is strictly meant to be a scientific information thread devoted to the taxonomic classification and identification of scorpions.

    As I have little time to search through the Scorpion forum for other information previously that may be relevant to this thread; I would ask that if any of you guys come across taxonomic information or a species ID key already posted in the Scorpion Forum that you PM me with a link to the pertinent post and I will move or copy it to here.

    Lastly; When posting new information here please label your post title with species/genus/famliy information to further cross referencing and make it easier to use the search function. Also, reference somewhere in the body of the post who made the new re-classification or ID key.

    Thanks

    here's some of my previous posts:

    The family name Liochelidae is changed to Hemiscorpiidae. Hemiscorpiidae
    includes the same genera and species as Liochelidae + the genus
    Heteroscorpion from Urodacidae.

    The family Urodacidae is abolished, and Heteroscorpion is transfered to
    Hemiscorpiidae and Urodacus is transferd to Scorpionidae.

    The complete article is freely available at the Euscorpius Journal homepage:

    Acosta & Fet (2005) have changed the spelling of P. leiosoma back to P. liosoma (no "e")

    Androctonus taxonomic changes

    Hi,

    Some new taxonomic changes in the genus Androctonus (13 species now) from Lourenço. He just gave me his paper today but it's from March (Lourenço W.R., 2005. Nouvelles considérations taxonomiques sur les espèces du genre Androctonus Ehrenberg, 1828 et description de deux nouvelles espèces (Scorpiones, Buthidae). Rev.Suisse de Zool. 112(1):145-171) :

    - A.amoreuxi : the subspecies A.a.amoreuxi is placed in synonymy of A.amoreuxi, and all the forms found in Middle East and Asia (the two other subspecies A.a.levyi and A.a.baluchicus) are not considered belonging to A.amoreuxi. A.a.baluchicus is now considered as a valid species A.baluchicus. The status of A.a.levyi is still unclear. The species A.amoreuxi is now only found in North Africa, perhaps in Israel.
    - A.australis : all subspecies (A.a.australis, A.a.africanus, A.a.garzonii, A.a.hector, A.a.lybicus) are placed in the synonymy of A.australis, which is considered as a polymorphic species.
    - A.bicolor : subspecies A.b.bicolor and A.b.aeneas are placed in synonymy of A.bicolor. A.b.liouvillei is considered as a valid species : A.liouvillei.
    - A.mauritanicus : both subspecies (A.m.mauritanicus and A.m.bourdoni) are placed in the synonymy of A.mauritanicus.
    - A.crassicauda : subspecies A.c.crassicauda is placed in synonymy of A.crassicauda, and A.c.gonneti is considered as a valid species : A.gonneti.

    - A.baluchicus (A. amoreuxi baluchicus before the revision).
    - A.liouvillei (A. bicolor liouvillei before the revision)
    - A.gonneti (A. crassicauda gonneti before the revision)

    - 2 new species : A.maelfaiti (India) and A.dekeyseri (Senegal and Mauritania)

    - And 3 others non changed : A.sergenti, A.hoggarensis and A.finitimus.

    Cheers,
    Eric

    Hi Oliver,
    I don't have the skills to judge the paper of Kovarik, but according some scorpiologists, this paper is not good. Photos are nice but totally useless to identify well an Heterometrus, and text seems to be very poor in information. The Couzijn or Tikader's books seems to be better to identify Heterometrus spp.
    Cheers,
    Eric

    Yes, I read the discussion on scorpionfans about it and certainly his key seems to concentrate too much on colouring to differentiate the species. But also I think its a bit easier for non-scorpiologists to follow, then a key that needs a more in-depth knowledge of scorpion taxonomy, which is probably what most keepers of Heterometrus want since they tend to be beginners, just an opinion :)

    Hi
    the Couzijn key might be good to determine locality too, as he describes granularion of the Heterometrus in regards to where they come from (the old subspecies)

    but Kovariks pictures help enormously!!
    though the lack of H.laoticus and other pictures leaves a large hole of knowledge which needs to be filled
    and it doesnt take into account differences in shape and granulation of different populations, ideally there would be pics of females too :(

    North American Family and Genera ID Key

    Here is a link to Scott Stockwell's paper Systemic Observations on North American Scorpionida with a Key and Checklist of the Families and Genera. It is a pdf and slow loading at times. This link was brought to my attention by Chad today and I thought I would add it here.

    Hi Jacobo,

    The genus of Tityus is a complete mess moreso than Centruroides LOL. No key will help. There is to much polymorphism/variation.....

    Search the various papers for Lourenco et. al. Some good some not. :confused:

    Regards.

    Hi,

    the latest overview for the genus Euscorpius:

    FET V., SOLEGLAD M.E. & B. GANTENBEIN (2004): The Euroscorpion: Taxonomy and systematics of the genus Euscorpius Thorell, 1876 (Scorpiones: Euscorpiidae) in: Fet V. & Soleglad M.E. (eds): Proceedings of the 3rd Scorpiology Symposium (28th Annual Meeting of the American Arachnological Society, Norman, Oklahoma, June 24, 2004) – Euscorpius 17: 47-60

    You just have to add E. concinnus which is described here:

    VIGNOLI V., SALOMONE N., CARUSO T. & F. BERNINI (2005): The Euscorpius tergestinus (C.L. Koch, 1837) complex in Italy: Biometrics of sympatric hidden species (Scopriones: Euscopiidae) – Zoologischer Anzeiger 244 : 97-113

    Offcourse it's obvious that Couzijns' revision is the greatest of them all.;P

    Michiel Cozijn
    Yes, loving scorpions runs in the family


    I was just making fun, I did not read Kovariks paper (still busy with his paper on Babycurus)so I don't know which one is better.

    Hi Michiel,

    Both Heterometrus revisionary papers have their pro's and con's. Personally, I try to remain distant from taxonomic matters but am fast becoming an avid supporter of the use of molecular analysis for revisionary works; supported by good ol' morphological analysis. Nuff said!
