Notes

The morphogenetic processes of Uronemella filificum (Kahl, 1931) Song and Wilbert, were studied using protargol method. The stomatogenesis of U. filificum can be summarized as follows: membranelles 1-2, paroral membrane and scutica of the opisthe originate from the parental paroral membrane, while membranelle 3 in the opisthe develops from the parental scutica. The paroral membrane of the proter developes from the parental paroral membrane. The stomatogenetic sequences are similar to the previous descriptions for other related taxa. The phylogenetic position of Uronematidae is discussed in the light of morphogenetic data obtained.
