Didilia sp. (Tetradonematidae: Mermithoidea: Nematoda), a parasite of Phlebotomus sergenti in Portugal.
A tetradonematid parasite was found in the body cavity of a male P. sergenti with unrotated genitalia caught near Tavira, Algarve, Portugal. It was identified as Didilia sp. (possibly D. ooglypta) by body length (3.4 mm), position of the vulva (anterior) and the sculpturing of the egg shell. This is the first European record of Didilia.
