Cell and Tissue Research, 2005 Two questions are of interest concerning the male reproductive system in Gordiida: (1) is the epithelium surrounding the testis continuous or discontinuous and (2) is the type of spermatozoon as described at the transmission electron-microscopical level for the two species of Gordius typical for all Gordiida?

Further Evidence for the Absence of Bacteria in Horsehair Worms (Nematomorpha: Gordiidae)
Journal of Parasitology, 2009We used molecular techniques to characterize bacteria associated with the nematomorph Gordius robustus (Leidy). This worm is a parasite of the fall field cricket, Gryllus pennsylvanicus (Burmeister), which is infected with the symbiotic bacteria, Wolbachia. Because of this close association, our a priori expectation was that G.

It is well established that parasites in the phylum Nematomorpha induce suicide behavior of their insect hosts to bring adult worms to the appropriate habitat for emergence. It is not well established, however, whether other nematomorph-induced behavioral alterations occur before worm emergence.

Observations on a British hairworm, Parachordodes wolterstorffii (Nematomorpha: Gordiidae)
Journal of Zoology, 1983Males of the nematomorph Parachordodes wolterstorffi from the New Forest, Hampshire, England have been examined entire, in thick sections and in cuticle preparations by light (differential interference contrast) and scanning electron microscopy. Surface features, internal organization and cuticular fibres are described and illustrated.

Fifteen species of freshwater Nematomorpha have been described from India, five of which belong to the genus Chordodes. This paper describes one new species of horsehair worms (Nematomorpha): Chordodes lasuboni and a new record, C. moutoni from North-East India, which raises the total number of described species from India to 17.

Horsehair worm, Paragordius varius (Nematomorpha: Gordiida): New to the Fauna of Oklahoma
The Southwestern Naturalist, 2013Abstract During July 2011, collections of several freshwater horsehair worms were made at two sites (Mud and Salt creeks) in McCurtain County, Oklahoma. The specimens were subsequently identified as Paragordius varius (Leidy, 1851), which represents a new nematomorph for the state.

Three species of Nematomorpha were found in a survey of the ground beetles of Scottish agricultural land, Gordionus violaceus (Baird) and two undescribed new species, G. linourgos sp. nov. and G. diligens sp. nov. The morphology of all three species is studied with the aid of SEM, and the characteristics of the cuticle and the male terminal lobes ...

Gordiid larvae enter and encyst within a large variety of aquatic vertebrates and invertebrates. Cysts of a single species of gordiid have been found in such diverse hosts as insect larvae, snails, crustaceans, fish, and many others. One particularly surprising host report was made nearly 100 yr ago, i.e., cysts within adult trematodes.

Description of Gordius attoni sp.n. (Nematomorpha, Gordiidae) from Northern Canada
Canadian Journal of Zoology, 1980Gordius attoni sp.n. (Nematomorpha, Gordiidae) is described using a scanning electron microscope (SEM) and conventional methods. The presence of white spots, the postcloacal crescent on the male caudal end, and the shallow interareolar furrows devoid of pores and bristles as seen in SEM are characteristic of the genus Gordius.
