Light and Electron Microscopic Studies of the Hindgut of Isophya nervosa (Orthoptera, Tettigoniidae)

ABSTRACT Isophya nervosa (Orthoptera, Tettigoniidae) is especially localized in Ankara, Çankırı, Eskişehir, Turkey. Although there are many systematic and taxonomic studies on I. nervosa, there is no study on the morphology and ultrastructure of the digestive. For this purpose, the hindgut of Isophya nervosa (Orthoptera, Tettigoniidae) was investigated by using light and electron microscopes in detail. The outer surface of the hindgut is covered with connective tissue and muscle layer containing abundant trachea. The lumen of all parts of hindgut (ileum, colon, rectum) is surrounded by a cuticular intima that lines single layer cuboidal epithelium throughout the entire length of the hindgut. The monolayer cuboidal epithelium in the colon, which is the middle part of the hindgut, has deep folds. The rectum is a wide elongated sac and has six rectal pads.
