Apenes nebulosus - Apenes nebulosa

Consistent with Apenes nebulosa

based on my microscopic examination of this specimen which is now a photo-voucher in the P.W.Messer collection. My disclaimer below in which I cannot rule out Apenes pallidipes still holds. I have been unable to track down the pertinent species accounts by Chevrolat or Chaudoir. Thanks Eric.

Eric, the 4th digit of your internal reference number on your hand-written label was smudged. Your Excel document says "10391" but hand-written label could be read as "10311".

Apenes nebulosa LeConte, 1866:364

On the MCZ website and checking the holotype of this species, the image is definitely IDed ok. It is A. nebulosa LeC. Remember all, please include the author and I'll try to keep you updated on the literature.

LeConte, J.L. (1866a) Additions to the coleopterous fauna of the United States, No. 1. Proceedings of the Academy of Natural Sciences of Philadelphia, 1866, 361-394.

Thank you for the confirmation

and the reminder to include author names more frequently in our discussions. Unfortunately, author fields are not available when new species names are entered in the current version of BugGuide. Hopefully version 2.0 will address this.

Moved from ID Request.

Fantastic! A new species for BG. Peter can correct me if the taxonomy has changed, but this was A. nebulosus when I lived and collected in AZ.

"Apenes nebulosa" is now accepted

as the proper gender (feminine). BugGuide should also change masculine "A. lucidulus" to feminine "A. lucidula". Blaine, whether Eric's specimen is truly Apenes nebulosa LeConte, 1866 remains to be seen as I study your mailed specimen of same and rule out Arizonan A. pallidipes (Chevrolat, 1835). I'm not yet convinced in my own mind that this submission is "Apenes". I wish the lighting of photo was better. In meantime Blaine thanks so much for the AZ material!

Apenes nebulosa

is a species I now feel more comforatble with after studying your specimen Blaine and testing it against the key by G. H. Horn (1882) on North American Apenes (4 species known then vs 6 now). I would say the image fits my perception of that species. Just to be complete however, I was unable to find descriptive information on apparently rare Arizonan "Cymindis"-Apenes pallidipes (Chevrolat, 1835): species no. 153 in Coleopteres du Mexique, fasc. 5 - 8 OR on synonym Apenes marginipennis Chaudoir, 1875: 24 in Bulletin de la Societe Imperiale des Naturalistes de Moscou 49(3): 1 - 61 OR on synonym Apenes mexicana Chaudoir, 1875: 25, ibid. V. Belov, you have a knack for finding such items on the internet. Any ideas here?

gender

I originally had this as feminine (as I remebered it as such), but switched it to masculine according to Bousquet and Larochelle's 1993 catalogue :)

i can get a better photo

I was merely hoping to clarify the genus on this photo, and so didn't try exceptionally hard to get the best photo I could. Is there any key feature you'd want to see to help clarify the situation?

Brighter, clearer, perpendicular view needed

of the dorsal habitus and ideally same of pronotum close up. The chance for accurate carabid identification improves when following the photo tips under section Coleoptera-Family Carabidae-Ground Beetles. Eric, if you feel it is important, you do have the option of mailing this specimen and other carabids to me as "photo-vouchers" for accurate species determinations that are not image-dependent. Thanks.

… Peter W. Messer, 7 August, 2010 - 8:23am

I added a close up of the pro

I added a close up of the pronotum...does that help at all?

… Eric Moody, 12 August, 2010 - 8:22pm

Yes, helps

to see characteristic pronotum with disc densely rugose and base sinuate ending in a median lobe.

… Peter W. Messer, 12 August, 2010 - 9:36pm

Cool!

I knew this looked different, but didn't think it would be that different. Thanks for the help!

… Eric Moody, 6 August, 2010 - 8:13pm

cool. thanks guys

no bembi for sure; maybe a Tetragonoderus... or even a lebiine
