Freshwater hairworms (Gordiaceae) and marine hairworms (Nectonematoidea) comprise the phylum Nematomorpha. Only the freshwater forms are discussed here. While freshwater hairworms develop as parasites of both aquatic and terrestrial arthropods, they all enter fresh water to mate, oviposit and produce infective stages (preparasitic larvae). The global species diversity of freshwater hairworms based on published descriptions is approximately 326 species and a conservative estimate for the global…

Nematomorpha (Horsehair Worms)

The phylum Nematomorpha, the hairworms, occurs worldwide and all members are developmental parasites of aquatic or terrestrial invertebrates, whereas the remaining species occur in freshwater as free-living stages or inside terrestrial hosts.

New hairworm (Nematomorpha, Gordiida) species described from the Arizona Madrean Sky Islands

This species represents the second new hairworm to be described from the Madrean Sky Islands, and it may represent the first endemic hairworm from this biodiversity hotspot.

Chapter 15 – Phylum Nematomorpha

Comparative descriptions of non-adult stages of four genera of Gordiids (Phylum: Nematomorpha).

This work describes and compares morphological characteristics of non-adult stages for nine species of African and North American gordiids from four genera (Chordodes, Gordius, Paragordius, and Neochordodes) and indicates that g Gordiid larval morphology can be used for predicting cyst morphology among other gorduid genera.

Novel techniques for biodiversity studies of gordiids and description of a new species of Chordodes (Gordiida, Nematomorpha) from Kenya, Africa.

Morphological characteristics of egg strings, eggs, larvae and cysts of C. kenyaensis were most similar to other gordiids in the genus Chordodes but differed morphologically from other gORDiid genera for which similar information is available.

Parasitism of Ground Beetles (Coleoptera: Carabidae) by a New Species of Hairworm (Nematomorpha: Gordiida) in Arctic Canada

Morphological examinations indicate that the hairworms collected from all locations represent a single, new species of Gordionus, making it only the sixth hairworm species and the third species of that genus found in Canada.

Ecology of Gordian knots in natural conditions

Because the water levels in the sampling stream decrease as the season progresses, males in knots attached to floating substrates could be in a better position to cope with decreasing water levels, as they always remain immersed.
