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.
