Anthribidae > Brachycorynus sp? - Euparius paganus

Anthribidae > Brachycorynus sp? - Euparius paganus
Middleburg, Clay County, Florida, USA
July 11, 2009
Size: 4.4mm
Collected at light. This keyed out in American Beetles Vol II as Brachycorynus, but I could not find
any reference in BGN. With the Fl Beetles checklist site down, did not have any other
source that I could find to flesh it out further. Then again, my track record for keying weevils is less than
stellar. Assistance appreciated. Thanks

my money is on Euparius paganus
will ask Dr. Valentine to check

 
ID confirmed by Dr. Valentine
His comment: "Euparius paganus Gyllenhal, 1833, found from Quebec to Florida, west to Iowa, Kansas, and eastern Texas. The two pale rings on each tibia are distinctive. For years this was a synonym of the more common E. marmoreus (Olivier, 1795), but I raised it to species level in 1960. The two species coexist over most of the eastern U.S., and are ocasionally even found on the same polypore. A neat feature is that each shows geographic north-south variation -- with the greatest extremes between northern marmoreus and southern paganus, and the most similarity in between. Of the many hundreds of specimens seen, three suggest possible hybrids. I'd love to know what keeps them separate. E. marmoreus averages larger, but size overlap is considerable. I suspect that because these are among the most abundant anthribids in collections, and constitute the largest genus of polypore feeders in the family, they are partly responsible for the common name fungus weevil. Most anthribids are wood borers (fungus present or not), a few feed on pollen, and a few are predators."

 
Euparius paganus
V: Thank you ever so much for the research, time and effort you put
into this one. I must thank Dr. Vanentine as well. I try to get as
much info as possible on as many of the critters as I can to keep on
file. This sure adds to the data base. Thanks again. Bruce

 
Euparius
V: You want to know what irritates me so much: E. paganus on the
guide page, is directly above my submission of E. marmore*us. Some
times, I think I need to collect rocks instead. Thanks.

 
no rocks for you:
[i] your contributions to BG are too valuable to lose you to geology; and [ii] you'll never get such an excitement from the rocks as you're getting from living things -- just my opinion...
