Dog-Eared Spider - dorsal - Bucranium - male

Dog-Eared Spider - dorsal - Bucranium - Male
Santa Ana NWR, Hidalgo County, Texas, USA
September 14, 2009
Size: 3mm
Bucranium sp. (thomisidae) from the Texas A&M collection. Det. D.A. Dean. (recently moved from Majellula)

Collected by Ed Riley and Mike Overton.

This is the only specimen found of this genus north of Mexico. If it is Bucranium affinis, as it appears to be, it may be the first male ever found. At least one female is known from Mexico and one from Ecuador. The description of the female exactly matches this male.

Some of the photos show purple on the spider's cuticle, but the specimen has no purple on it. The purple appears to a very minor degree in each photo of the stack, and Helicon Focus chose to merge them all together into large purple blobs. I think the purple was a result of using an LED light at a low setting and long exposure.

(Sometimes I'm not sure what to title these images.)

Totally
Awesome!
Congratulations on such a great find.

Change to Bucranium sp.
Allen would like this re-designated Bucranium sp. I was copying the label found in the vial, but here's his response to my listing it as B. affinis:

"Please change the name to Bucranium sp. There are 4 species of this genus known. A male from Cuba is known. I just noticed that both sexes of a species are known from South America. The one we have is likely affinis with the female from Mexico. Until it is studied better, there is uncertainty. Thanks."

Dog-Eared Spider
So cool. Nice one Joe!

race condition
Oops. Sorry, looks like we had a race condition. I moved everything back to the right place.

 
No problem
Very interesting spider.

 
more interesting still
Things just got even more interesting. I added this blurb: "It appears that this is the first male ever found. At least one female is known from Mexico and one from Ecuador. The description of the female exactly matches this male."
