New Data on the Morphology and Distribution of Oswaldocruzia Skrjabini (Nematoda, Molineidae)

Open access

Sixteen specimens of Oswaldocruzia (Nematoda, Molineidae) were found in the material from Zootoca vivipara Lichtenshtein, 1823 collected in Ukraine. The nematodes were identified as O. skrjabini Travassos, 1937 due to the presence of well-developed cervical alae and the host species. Based on the specimens examined, an amended description of the species, with new morphological characters and metrical data, was composed; its distribution in Ukraine was outlined. Oswaldocruzia skrjabini differs from other species of the genus by the presence of extra branches on spicular fork and shoe.
