T. simplex - Thalpius simplex

T. simplex - Thalpius simplex
17 km sw Montezuma, 944 m, Sonora, Mexico -- voucher specimen
July 22, 1980
det. R. Davidson
specimen curated at UAIC

Mexico, but I thought Peter might want to see this, too.

Frass or keep?
This specimen being from Mexico, should the entry be frassed once Peter has a chance to look at it? Or, because it's the only image of this species in the Guide so far, should it be kept around until one of these is collected from the Guide area?

I think it should be kept for now
I photographed it especially for BG. These order spp may be be found in TX, NM, or AZ soon.

I agree that we post "Mexican" species,
especially when the following conditions apply: 1) a difficult group to identify to species level; 2) various species ranges are poorly known. Both conditions apply to members of Zuphiini. Recall that the northern portion of Mexico is included in "North America"/"Nearctic".

Thalpius simplex
has the distinction of having the largest convex eyes among the 10 species of Thalpius known in North America including Mexico. Among the ten, this is the only species that still no US record.

Having such an image is very useful while I work on another Mexican Thalpius recently found in TX -- a new US record! That discovery led to my review of the entire group and a synthesis of the first comprehensive (English) key to the 10 species known in North America. I'm not yet sure if I'll post the key on BugGuide before I submit it with a journal publication of the new US record.

I look forward to more images and possibly mailed specimens of Thalpius for identification.

"Proof" that BugGuide should post Mexican species:
In newly examined material I discovered that several specimens of Pseudaptinus (Thalpius) simplex were given Texas locality labels -- making this the 10th member of Thalpius known in the United States. Therefore, having had a representative image of T. simplex in BugGuide (even if just from Mexico) was indeed a useful venture. Unfortunately this latest discovery did not make it in time to be included in my forthcoming paper on North American Thalpius which reports the 9th North American member, namely, Pseudaptinus (Thalpius) nobilis.

Great discovery anyway
If you write another paper and need the location data of the UAIC - we are getting closer to a full specimen based data collection

Moved from Zuphiini.
