April 9, 2006

Reichenbachia corporalis
A female, but placeable.

Staphylinidae: Pselaphinae: Reichenbachia sp.
A different one; bring it along tomorrow.
The maxillary palpi in Pselaphinae vary tremendously in form, and are one of the critical features in identifications. Some are truly bizarre, such as in Pselaphus, which perhaps someday will be picked up by Tom or others. Sensory in function, used to triangulate prey.

Nice shot!
Look at those unusual palpi. I wonder why they're shaped like that. Maybe Don knows.
