Ptenothrix beta

No idea, really...
Christiansen & Bellinger 1981 did not provide an etymology...
In the description they mention that it is the only Ptenothrix with clavate tenent setae (distally on the legs just above the claw). I guess they used 'beta' refering to the Greek character to express the difference with all the other 'alpha' forms having non clavate tenent setae.

thanks, Frans
failure to include a name derivation clause makes it available to interpretation, so i will stick to the vegetable connotation: beet-belly springtail it is then

is this a ref to beets or to the Greek letter?
the former makes more sense to me
