Nematodes of the genus Crenosoma M o 1 in., 1861 parasitize in the bronchioles of Carnivora and Insectivora mammals in Holarctic region. In the opinion of numerous specialists they manifest a specificity in respect to the definitive host. A great number of publications about the species of the genus Crenosoma have appeared in the last decades. Some of them describe new species, others only report data about their distribution. Very few give any information about their morphometric characterization and this information in most cases is incomplete. The lack of sufficient studies of Crenosoma morphometry and particularly of the copulatory organ of the male individuals and the area around the vulva in the females is a serious obstacle in elucidating the taxonomic status of some doubtful species and in improving the taxonomy of nematodes from the genus Crenosoma. The present investigation, including abundant helminthological material, represents a study on the morphology and taxonomy of species from the genus Crenosoma found in Bulgaria.
