Figure 5. SEM images of the head and maxillipeds of Anonyx nugax (a–f) and Tmetonyx cicada (g–l). (a) Lateral view of the head with intact mouthparts. (b) Head with maxillipeds in situ seen in ventral view. (c) Right maxilliped in aboral view. (d) Distal portion of the left maxilliped in situ showing the palp and the outer plate in ventral view. (e) Inner plate of the left maxilliped in oral view. (f) Part of the distal tip in oral view showing two pairs of cuspidate setae. (g) Lateral view of the head with intact mouthparts. (h) Head with maxillipeds in situ seen in ventral view. (i) Maxillipeds in oral view. (j) Inner plates of maxillipeds in oral view. (k) Triangular processes at the anterior margins of the inner plates. (l) Oral surface of the outer plate showing pores along its medial margin in oral view.
