Thanks for posting a picture of the male abdomen -- it makes identifying corixids halfway possible! Would you happen to know whether this image is actually a mirror image? If not, then this is a very interesting specimen. The male strigil for Trichocorixa is generally on the specimen's left side, not the right side as pictured here.

Thanks for asking!
This image was taken through a reflecting microscope, and is definitely a mirror-image.

Rats. The location of the strigil is an important character for identifying corixids. Trichocorixa is a bit different from most other genera in that the strigil is ordinarily on the left. Occasionally, you'll see a corixid specimen that will have the strigil on the opposite side from where it should be -- kind of like left-handedness, only much more rare. When I saw your specimen, I suspected the image was reversed, but hoped that it was the corixid that was reversed.
