Spotted Longicorn (Eburophora octoguttata) -male An attractive dark brown longicorn with medium-length black antennae and thick femurs. Elytra had small pale yellow spots. The beetle would have been about 18 to 20 mm long.<br />
Spotted on black wattle (Acacia mearnsii) - in a national park.<br />
My thanks to WildFlower and Martin Lagerway for their help with the ID.<br />
Note that this particular specimen is a somewhat aberrant colour form with extra spots as compared to the usual &quot;factory issue&quot; Eburophora octoguttata. <br />

    1. Thank you so much WildFlower. I will check all of the information. Description sounds good, with spinose apices and males having shorter antennae. Could be a variant ??. Maybe Eburophora species anyway. Thanks again. Posted one year ago
      1. There are two described Australian species in this genus
        https://bie.ala.org.au/species/urn:lsid:biodiversity.org.au:afd.taxon:b61c9d59-61e9-48fd-9669-916c4d465601#classification
        It cannot be the first species according to the Longicorn volume by A Slipinski (P 408). E. octoguttata is the only possible described species. I am confident this is correct.

        1. I couldn't find anything on E.eburata. So, thanks for the confirmation Martin.This one has chosen to go with a few extra spots perhaps - more interesting. I'll go with E.octoguttata. Thanks to you both. Posted one year ago
          1. After browsing through the available pages (on google preview) of the book by Slipinski & Hermes, to me it looks like Eburophora is indeed a very good bet for the genus, but the pattern is so different from all images of octoguttata that I found, that I decided to write the authors of the book and ask for their opinion.
            If it is an Eburophora it just might be an as yet undocumented colour aberration, or maaaayyyyybeeee even an undescribed new species (???) so they _might_ just be interested in the critter too. Then again, maybe it's something completely different or a well known colour form and I was just to daft to find it :o)
            Anyway, @Leuba : It probably wouldn't hurt if you could find a specimen with this pattern again and collect it?!
            Cheers, Arp

            1. Mistery solved: Dr. Adam Slipinski replied that he has seen specimen of octoguttata with variable spots much like this one before, so he is confident it should be that species (well done on the initial ID WildFlower!! :o) He goes on to mention that it is not a common species and is happy with the extra record.
              That said, as Hermes Escalona mentioned in his reply, it is always good to be able to study various details of aberrant specimen up close and personal to double check for a possible new species ... ;o)
              Cheers, Arp

              P.S. I've uploaded the image by White (1855) to also document the standard markings on JD:

              1. Wow - you certainly are no "Pudding4brains" !
                Thank you for your persistence and taking the trouble to write to the authors. Now we not only know that it is E.octoguttata but that it is not common and is one of a few ( ? 2 )on record. I must thank WildFlower and Martin Lagerwey for their help once again.
                Thank you !

  1. The original description of the genus Eburophora and the species E. octoguttata White 1855 is here:
    http://biodiversitylibrary.org/page/20061841
    pictured as Plate VIII fig.7 :
    http://biodiversitylibrary.org/page/20061928
    recent images by Slipinski & Escalona here:
    https://apps2.cdfa.ca.gov/publicApps/plant/bycidDB/wdetails.asp?id=20169&w=o

    The original description of E. eburata (as Sophron eburatus, Pascoe 1865) from South Australia is here:
    http://biodiversitylibrary.org/page/13387976
    images by Slipinski & Escalona here:
    https://apps2.cdfa.ca.gov/publicApps/plant/bycidDB/wdetails.asp?id=20168&w=o

    Waterhouse moves S.eburata to the genus Eburophora in 1874:
    http://biodiversitylibrary.org/page/14921890

    From this, it seems that the still valid genus Sophron and Eburophora would probably be quite similar in appearance, but there is only one Aussie species (Sophron inornatus) with a recent image here :
    https://apps2.cdfa.ca.gov/publicApps/plant/bycidDB/wdetails.asp?id=20238&w=o

    So back to the two Eburophora. To me the pattern on the photo is sufficiently different from both Eburophora to become somewhat suspicious ... maybe we should try to key out the species with the excellent key available here? :
    https://books.google.nl/books?id=d9OfDAAAQBAJ&pg=PA19
    Or with the website on Australian Cerambycidae:
