Hi Kip,
       Your beetles sound like they may have a somewhat similar
evolutionary origin to a bird sister-group pair, Hemiprocnidae and
Apodidae.   The Hemiprocnidae has a South East Asia range that is
broader, but centered around the Vietnam-Myanmar area.  
      It's sister group Apodidae apparently arose further west in
Eurasia (with at least one stem-genus known from Europe).  Your beetles
could have spread west into eastern North America along with Apodidae.
Of course, Apodidae has spread and diversified much further, but your
beetles could have had competitors that prevented them from expanding
into South America, Africa, etc.  Anyway, I would not be surprised to
find European fossils that are stem members of your North and Central
American beetle group.

Dear All, 
I am looking for examples of taxa with demonstrated sister groups in
which one is endemic to all or part of South East Asia and the other to
all or part of North and/or Central America. Any citations or clues
