I am sure that this specimen belongs to the subclass Cunaxinae.
The very narrow leg tarsi let me think that it belongs to the tribus Armascini. Another telling feature are the long sensillae sce. Detail to identify it exactly are lacking but I would say it is an Armascirus sp

Cunaxinae
Great find! These guys are classic sit-and-wait predators that use their long trichobothria (the four long hairs coming out of the anterior half of the body) to detect prey. They use their hardened, spiny pedipalps (seen in this photo raised in the "ready" position) to snag prey. You can also see in this photo the elongate gnathosoma (mouthparts) characteristic of most bdelloids.

On another note, my lab mate (Mike Skvarla) has been studying these guys for his masters and now for his PhD.
