A Scanning Electron Microscopic Study of Eggshell Surface Topography of Leidynema portentosae and L. appendiculatum (Nematoda: Oxyuroidea)

Author Institution: Department of Zoology, The Ohio State UniversityThe eggs of the nematodes Leidynema appendiculatum and L. portentosae were studied with scanning electron microscopy (SEM). The opercular grooves on the eggshells of both species are oblique, incomplete, and terminal. They deepen as the embryo develops. Numerous pores and pits are distributed on the eggshell surface in both species. The pits on the eggshell of L. portentosae are sharply delineated; those on the eggshell of L. appendiculatum are less sharply defined. The surface texture of the eggshell of L. portentosae is rougher than that of the eggshell of L. appendiculatum and sandy in appearance. The entire eggshell of both species is undulated irregularly to a very small degree
