Placing the spider in an ultrasound cleaner
removes much of the detritus (compare Figs. 2C and D), but some
still remained stuck directly on the cuticle (Fig. 2D and G), which
suggest that the soil particles might be mechanically retained in
place by the barbed setae and further consolidated on the cuticle by
the addition of water, differing from the small-particles adhesion
mechanism of Homalonychus and Sicarius (Fig. 7B and C), which
live in dry environments.
