Revision and new species of Trigonopselaphus

 I recently published the revision of Trigonopselaphus, a genus that includes some of the largest rove beetles known, with sizes ranging from 30-40 mm (trust me, this is huge size for rove beetles). The paper is available here. Previously I had blogged about the loss of the type for one of the species, Trigonopselaphus herculeanus. That species was described by Laporte and was lost in the Smithsonian fire back in the mid 1800s. So, as a good taxonomist that I am, I designated a new type (called a neotype) for that species.

I also described a new species from Ecuador and Peru, named Trigonopselaphus diplopegus. The epithet refers (of course) to the specific structure of the genitalia. But while I was working on this paper, these beetle heads looked oddly familiar.  And finally, a few days ago, I got it: anybody else see the resemblance?

Maybe little blue aliens do live among us after all.
