Zdzitowiecki et Boev, 1971 (Nematoda: Protostrongylidae) - First record in Alpine ibex ( Linnaeus, 1758) from Europe.

In the course of a survey of the endoparasites of Alpine ibex () from Austria, examination of the lungs revealed male nematodes presenting morphological characters which differed from those of the three species previously reported from this host. Fragments of 16 adult male and 4 adult female nematodes extracted from the lung tissue of two female ibex following peptic digestion were subjected to close microscopic examination. Based on their morphology, the lungworms were identified as Zdzitowiecki et Boev, 1971. This species was originally described from Siberian ibex () in Asia and previously only reported from this host from Kazakhstan and Mongolia. The identification of in Alpine ibex represents a new host and geographical record and reinforces the interest to further study the parasite diversity of wild ungulates for a better understanding of complex host-parasite associations and biogeography.
