We review recent advances in the use of non-adult gordiid cyst stages to locate gordiids over large geographical regions and new culturing techniques which can help overcome current difficulties in nematomorph biodiversity studies. Using these techniques, we collected a new species of gordiid as cysts in aquatic snails (Biomphalaria pfeifferi) from the Lake Victoria Basin, western Kenya, Africa and cultured them in the laboratory. We describe the adult free-living male and female worms using… Expand
Comparative descriptions of non-adult stages of four genera of Gordiids (Phylum: Nematomorpha).
TLDR
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.

Gordionus maori (Nematomorpha: Gordiida), a new species of horsehair worm from New Zealand
TLDR
Analysis of the mitochondrial CO1 gene and of the nuclear 18S rRNA gene showed that the new Gordionus specimens form a monophyletic clade, but with partly extensive internal genetic difference, indicating that cryptic species might be present. Expand
Chordodes ferox, a new record of horsehair worms (Nematomorpha, Gordiida) from South Africa
TLDR
Three females and one male specimen of a previously unconfirmed species of horsehair worms from South Africa are described using Scanning Electron Microscopy, finding the presence of enlarged and elevated simple areoles around the base of a thorn areole is characteristic. Expand
A new species of Gordius (Phylum Nematomorpha) from terrestrial habitats in North America
TLDR
The consistent occurrence of this gordiid in terrestrial habitats, along with its distinct egg morphology, suggests that this new species of hairworm has a terrestrial life cycle. Expand
Chordodes combiareolatus, a new species of horsehair worms (Nematomorpha) from Nagaland, India, with further comments on Chordodes moutoni.
TLDR
Two female specimens found on two occasions on a terrace paddy field in Tsupo, Viswema, Kohima, Nagaland, India are reported, one of which shows a new type of cuticular structure, the areoles, which combines characters of both simple areoles and tubercle areoles. Expand
Using Gordiid cysts to discover the hidden diversity, potential distribution, and new species of Gordiids (Phylum Nematomorpha).
In this study, we sampled aquatic snails for the presence of hairworm cysts from 46 streams in Payne County, Oklahoma. Gordiid cysts were found at 70 % (32/46) of sites examined. Based on cystExpand
A new orthopteran-parasitizing horsehair worm, Acutogordius taiwanensis sp. n., with a redescription of Chordodes formosanus and novel host records from Taiwan (Nematomorpha, Gordiida)
TLDR
A description of a new species of horsehair worm, Acutogordius taiwanensis sp. Expand
A New Species of Gordionus (Nematomorpha: Gordiida) from the Rocky Mountains of New Mexico.
TLDR
This is the third Gordionus species described from high-elevation streams within the southern Rocky Mountains, and it appears that this high-altitude habitat represents the preferential niche for numerous species of this genus, and thus future work should focus on describing gordiid diversity in other parts of the Rocky Mountains. Expand
Chapter 15 – Phylum Nematomorpha
TLDR
This chapter reviews all pertinent information on the general biology of freshwater gordiids and provides new information on hairworm life cycles and novel sampling and culturing techniques for this fascinating group of freshwater invertebrates. Expand
Annual Survey of Horsehair Worm Cysts in Northern Taiwan, with Notes on a Single Seasonal Infection Peak in Chironomid Larvae (Diptera: Chironomidae)
TLDR
Samples from the subfamilies Tanypodinae and Orthocladiinae were less parasitized, which indicates that the feeding behavior of the chironomid host likely affects horsehair worm cyst infections; however, bioconcentration in predatory Chironomids was not detected. Expand

Redescription of the African Chordodes albibarbatus Montgomery 1898, and description of Chordodes janovyi n. sp. (Gordiida, Nematomorpha) and its non-adult stages from Cameroon, Africa
TLDR
Chordodes janovyi belongs to a large group of Chordodes in which simple areoles are smooth or superficially structured less so than “blackberry” areoles, and is most similar to the African Chords gariazzi Camerano 1902 and Chordode heinzei Sciacchitano 1937. Expand
A new horsehair worm, Chordodes formosanus sp. n. (Nematomorpha, Gordiida) from Hierodula mantids of Taiwan and Japan with redescription of a closely related species, Chordodes japonensis
TLDR
A new species of horsehair worm is described and compared to a closely related species, Chordodes japonensis, and the significantly longer filaments on the female crowned areoles can be used as diagnostic characters for the new species. Expand
Redescription and compilation of Nearctic freshwater Nematomorpha (Gordiida), with the description of two new species
TLDR
The two new species described here raise the number of gordiids known from the Nearctic region to 17, and from the 30 species names used for Nearctic nematomorphs, 15 are regarded as valid species. Expand

TLDR
It is reported that the occurrence of gordiids on the basis of the cyst stage is much more common than previously reported, thus altering the perception of how common these worms are. Expand
