Globular Springtail - Sminthurus bivittatus

Globular Springtail - Sminthurus bivittatus
Fort Bragg, Cumberland County, North Carolina, USA
February 2, 2006
Size: around 2 mm
I found my first two of these today. This species has white stripes down the rear. I'm guessing the little red spot is some kind of mite. Judging from my cat lately....an earmite :).

Sminthuridae
Hi Lynette. This specimen seems to resemble well with the recent image of Tom Murray.

 
Thanks
However, I've found two pages one is spelled Sminthuridae and the other is Sminthurididae. I can find both on the internet, so do you know which is current or correct?

 
Actually, we think both are
We seem to remember Tom Murray commenting on this so you can check with him. Unfortunately we don't know which genera are in which family, but Tom might!

 
Sminthurus bivittatus
Hi Lynette, John and Jane. Sminthuridae and Sminthurididae are two different families. To find out more about the systematics of Collembola you might want to visit collembola.org. There you can find the taxonomic hierarchy from family level to species level for more than 7000 species of Collembola. And much more...

 
Thanks
I think creating family names like that is just wrong!! :)

 
Sminthurididae
Hi Lynette. It seems weird to create such names, I agree. This is the story behind it: in the beginning there was only Sminthuridae. At a given time taxonomists decided to create a subfamily of Sminthuridae to organise all related species. According to ICZN name rulings the name of this new subfamily became Sminthuridinae (= Sminthurid (= stem of family) + inae (= standard suffix used to indicate subfamilies)). After some time when more species were added to this subfamily, taxonomists decided that it was time to raise the subfamily to family level. In line with standard name rulings Sminthuridinae became Sminthurididae (idae = standard suffix for families). Are you still with me? ... ;-)
