摘要：
Two new species of Ungella Cobb, 1928 are described from earthworms deposited in the collection of the Smithsonian Institution Natural History Museum. Ungella burmensis sp. n. is distinguished from U. secta Cobb, 1928 by having finely mammilated egg shells, smaller gubernaculum and more numerous pre-cloacal papillae. Ungella mexicana sp. n. differs from other species in the genus by having bifurcated spicule termini. The presence and absence of spicular apparatus within the ungellid genera is discussed.
