4 lateral spots - Sminthurinus quadrimaculatus

4 lateral spots - Sminthurinus quadrimaculatus
Berkeley County, South Carolina, USA
March 17, 2007
Size: about 0.72 mm
This was my best image of a small katiannid I dislodged from the tough, pungent, polypore fungus from a downed swamp tupelo tree sent to me by Richard Lareau. It looks very similar to Sminthur*inus quadri*maculatus but with differences.

Sminthurinus quadrimaculatus
I have to reconsider my original ID and agree now with your original ID.
The reason why it looks different is that it is a juvenile specimen. Compare it with the pictures courtesey of Tom Murray of the early instars.
S. elegans has a thin middorsal longitudinal stripe, which is missing in this specimen...
Sorry for the confusion caused...

OK
I've placed it where it belongs. Thanks, Frans.

Thank you, Frans.
I was hoping it was a new species for bugguide but I see I beat myself with earlier submissions, followed by Graham. That happens to me frequently even in my forte, Coleop*tera :-)

Moved from Katiannidae.

Sminthurinus elegans
Sometimes, as in this specimen, the lateral white bands are transversally interrupted by interconnections of the longitudinal dark pattern bands. Then it appears that the specimen has 4 spots.
