Diagnosis

Isophelliidae with small pedal disc and cylindrical, elongate body. Column divisible into scapus and scapulus, the former with tenaculi and cinclides. Tentacles short, the inner longer than the outer, hexamerously arranged, more numerous than the mesenteries at the base. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal. 2 narrow siphonoglyphs. The mesenteries of the first cycle and at least half the mesenteries of the second cycle are definite macrocnemes, the other of this cycle may be more or less marked macrocnemes, but with weaker retractors than the former. Each pair of the second cycle consists of a stronger and a weaker mesentery, all arranged in the same manner in relation to the directive plane. Retractors of the macrocnemes strong, restricted, with high folds. Parietal muscles weak to rather well developed, basilar muscles distinct. Mesenteries of the first cycle and at least the stronger ones of the second, fertile. Cnidom: spirocysts, basitrichs and probably microbasic p-mastigophores and microbasic amastigophores.
