First record of adult Nematomorpha Gordius sp. from western Anatolia (Turkey)

The Gordian worm, Gordius sp. (Nematomorpha, Gordiidae), is reported from Topçam Reservoir (Aydın, Turkey) as the first record for the group from southwestern Anatolia. One adult female Gordian worm was found coming out of the anal aperture of a specimen of Aegean chub, Squalius fellowesii. The Gordius sp. was then described by means of microscopic observation. The morphological features of the specimen and original pictures are given.
