Fig. 3. Scanning electron micrographs of Aphrodes to show possible
proprioceptors associated with the proximal joints of a hind leg. (A) Lateral
to the hair rows on the coxa are two hair plates (black arrows) in the
hollowed region of the coxa that will accommodate the femur when the leg is
fully levated. A small group of long hairs (black arrow) project posteriorly
from the posterior and medial region of the coxa. A hair plate (white arrows)
is present on the lateral surface of a ventral horn of a trochanter as it
articulates with a coxa. Scale bar, 200 µm. (B) Detail of the two coxal
hair plates from the leg on the right (top broken box) in A. Scale bar, 100
µm. (C) The trochanteral hair plate, again from the leg on the right (lower
broken box) in A. Scale bar, 20 µm. All photographs in A–C are of
ventral views with anterior at the top. (D) Dorsal view of the trochanter to
show two long hairs. Note also that the dorsal femur has no protrusion. Scale
bar, 200 µm. (E) The boxed region in D at higher magnification. Scale bar,
100 µm.
