“…This single character has been taken to name a new genus, Semigordionus (Heinze 1952), with one species from Austria. Zanca and Schmidt-Rhaesa (2006) found it more appropriate to regard Semigordionus as a member of the genus Gordionus, but did not formalize this step, because further investigations of the posterior end of S. circumannulatus should be awaited.…”

The collection of horsehair worms in the Zoological Museum of the Centrum für Naturkunde (CeNak) of the University of Hamburg has been revised. All specimens have been investigated by Scanning Electron Microscopy (SEM). A total of 173 specimens from 135 catalogue entries is present in the collection, these represent 39 species from 10 genera (Gordius, Chordodes, Paragordius, Parachordodes, Gordionus, Acutogordius, Beatogordius, Paragordionus, Pseudochordodes, Nectonema). Previous revisions of the Nematomorpha material have been done in 1893 by Römer and in 1935 by Heinze. A number of species could not be determined to species level, either because characters were not preserved well enough or because observed characters did not fit available species descriptions. This does account in particular for the genus Gordius, where diagnostic characters are few and great uncertainties exist concerning the status of certain species. Therefore, within this genus, many records were only determined as Gordius sp., including some specimens that had previously been determined to species level. One new species is described from the material of the collection. This species is named Chordodes jelkae sp. n. and it is characterized by the presence of an apical tuft of bristles on simple areoles in combination with the absence of thorn areoles. The holotype of Chordodes pilosus Möbius, 1855 was reinvestigated, and its species identity cannot be determined unambiguously. Therefore the name Chordodes pilosus is considered a nomen dubium.

“…Nematomorphs are arthropod parasites and are found in freshwater and marine habitats. The freshwater nematomorphs or gordiids (Nematomorpha: Gordiida), are parasites largely of orthopterans, coleopterans, and mantids (Hanelt et al 2005) and contain about 350 species within 18 genera (Schmidt-Rhaesa 2001a; Zanca & Schmidt-Rhaesa 2008).…”

The phylum Nematomorpha contains approximately 350 species in 19 extant genera. The genus Gordionus contains 56species, four of which occur in the contiguous United States of America. Here we describe two new Gordionus speciesfrom the southern Rocky Mountains. Worms were collected at three sites in the Santa Fe National Forest in northern NewMexico in the southernmost tip of the Rocky Mountains. Sites consisted of first order streams above 3120m in aspen/pinewoodland. Gordionus lokaaus n. sp. has flat, polygonal or roundish, areoles covering all parts of the body. The male cloa-cal opening is surrounded by broad bristles with stout apexes forming a unique tube-like opening. Adhesive warts aresmall and postcloacal spines are thin and triangular-shaped. Gordionus bilaus n. sp. also has flat polygonal or roundshaped areoles, but has indistinct interareolar furrows making neighboring areoles appear fused. The male cloacal openingis surrounded by stout, finger-like bristles in 2‒3 rows. Adhesive warts are larger and postcloacal spines are broad andmound-shaped. These species double the number known from the state of New Mexico and are the first gordiids described from the southern part of the Rocky Mountains.

“…Approximately 350 species of gordiids have been described worldwide from 18 extant and 2 extinct genera (Schmidt-Rhaesa, 2001b;Zanca and Schmidt-Rhaesa, 2008). Despite a recent flurry of taxonomic activity on this group, only about 30 species have been recognized from North America (Schmidt-Rhaesa et al, 2016;Swanteson-Franz et al, 2018).…”
