Scanning electron micrographs showing posterior end of male Physaloptera clausa . A, caudal alae (CA), and spicule (S). Bar= 429 μm. B, Caudal alae (star), four stalked precloacal papillae (PrCP), three postoacal papillae (PoCP), and cuticular ridges (CR). Bar= 375 μm. C, Higher magnification of four of stalked precloacal papillae (PrCP), and cuticular ridges (CR). Bar= 75 μm. D, Stalked precloacal papillae (PrCP), postcloacal papillae (PoCP), three (arrowhead) and four (arrows) sessile papillae directly to anterior and posterior to cloaca, respectively,left spicule (LS), and cuticular ridges (CR). Bar= 100 μm. E, Stalked precloacal papillae (PrCP), postcloacal papillae (PoCP), and phasmids (Ph). Bar= 150 μm. F, Higher magnification of postcloacal papillae (PoCP), and phasmid (Ph). Bar= 60 μm.
