Pseudoscorpion - Apochthonius

Pseudoscorpion - Apochthonius
Cowichan Valley, British Columbia, Canada
September 17, 2013
Size: 1.40 +- 0.05mm BL
Found in moss. I've been finding quite a few like this and am convinced they're all in genus Apochthonius based on the differing number of segments on legs I/II vs. III/IV, the position of the transverse trichobothrium on the chelal hand, and the coxal spines confined to coxa I. I'm unsure of the species. There are only 8 setae on the anterior margin of the carapace, which suggests it's not A. minimus or A. moestus (see Benedict & Muchmore 1976), unless it's a juvenile (if not, I think it's a female).

As always, this pseudoscorpion was photographed live and unharmed.
