(1)The infectional state of the cysticercoids of R. tetragona and R. echinobothrida in the abdominal cavity of Tetramorium caespitum jacoti WHEELER, the intermediate host of the two cestodes, are shown in Table 1. Table 1 indicates that it is difficult to distinguish the two species only by the study of infectional state of cysticercoids. (2)Table 2 illustrates morphological differences between the two kinds of cysticercoid. The cysticercoids of R. tetragona (Fig. 1A) are generally slender in form than those of R. echinobothrida (Fig. 1B). Suckers of the former are more slender than those of the latter and acetabular hooks of the latter (Fig. 2A) are longer and more variable in shape than those of the former (Fig. 2B). Rostellar hooks of the former (Fig. 3A) are arranged in a single row, armed with about 100 hooks, while those of the latter (Fig. 3B) in two rows, armed with about 200 hooks.
