Acutogordius is a genus of worms belonging to the family Gordiidae. [1]
The species of this genus are found in Northern America, Malesia. [1]
IRMNG lists the following species:
Nematomorpha are a phylum of parasitoid animals superficially similar to nematode worms in morphology, hence the name. Most species range in size from 50 to 100 millimetres long, reaching 2 metres in extreme cases, and 1 to 3 millimetres in diameter. Horsehair worms can be discovered in damp areas, such as watering troughs, swimming pools, streams, puddles, and cisterns. The adult worms are free-living, but the larvae are parasitic on arthropods, such as beetles, cockroaches, mantids, orthopterans, and crustaceans. About 351 freshwater species are known and a conservative estimate suggests that there may be about 2000 freshwater species worldwide. The name "Gordian" stems from the legendary Gordian knot. This relates to the fact that nematomorphs often coil themselves in tight balls that resemble knots.
Carollia is a genus of bats often referred to as the short-tailed fruit bats. Along with the genus Rhinophylla, Carollia makes up the subfamily Carolliinae of family Phyllostomidae, the leaf-nosed bats. Currently, nine species of Carollia are recognized, with a number having been described since 2002. Members of this genus are found throughout tropical regions of Central and South America but do not occur on Caribbean islands other than Trinidad and Tobago. Bats of the genus Carollia often are among the most abundant mammals in neotropical ecosystems and play important roles as seed dispersers, particularly of pioneer plants such as those of the genera Piper, Cecropia, Solanum, and Vismia. Carollia are primarily frugivorous; however, C. perspicillata, C. castanea, and C. subrufa are known to feed on insects.
Procambarus is a genus of crayfish in the family Cambaridae, all native to North and Central America. It includes a number of troglobitic species, and the marbled crayfish (marmorkrebs), which is parthenogenetic. Originally described as a subgenus for four species, it now contains 161 species in 16 subgenera.
The thorny-headed worm family Polymorphidae contains endoparasites which as adults feed mainly in fish and aquatic birds. When this taxon was erected by Meyer in 1931, a subfamily Polymorphinae was established in it. As the Polymorphidae as presently understood would then be monotypic, with no basal genera outside the Polymorphinae, the proposed subfamily is redundant for the time being and therefore most modern treatments simply omit it. Polymorphus minutus is an economically significant parasite in goose and duck farming.
Oroperipatus is a genus of Neotropical velvet worms in the family Peripatidae.
Gordius is a genus of worms in the phylum Nematomorpha, the horsehair worms. It was formerly treated as the only genus in the family Gordiidae, but the genus Acutogordius is now considered as distinct. The genus is distributed worldwide except for Antarctica, where no Nematomorpha have been recorded.
Archotuba is a genus of elongated conical tubes that were seemingly deposited by colonial organisms. Known from the Chengjiang, its biological affinity is uncertain; it somewhat resembles the tubes of the 'priapulid' Selkirkia, but a cnidarian affinity is also possible. In the absence of soft parts, there really isn't enough data to confirm a biological affiliation.
Nectonema is a genus of marine horsehair worms first described by Addison E. Verrill in 1879. It is the only genus in the family Nectonematidae described by Henry B. Ward in 1892, in the order Nectonematoidea, and in the class Nectonematoida. The genus contains five species; all species have a parasitic larval stage inhabiting crustacean hosts and a free-living adult stage that swims in open water.
Gordioidea is an order of parasitic horsehair worms. Its taxonomy remains uncertain, but appears to be contained in the monotypic class Gordioida and contains about 320 known species.
Gordiidae is a family of parasitic horsehair worms belonging to the order Gordioidea.
Chordodidae is a family of parasitic horsehair worms belonging to the order Gordioidea; its taxonomy is under review.
Spinochordodes is a genus of worms belonging to the family Chordodidae.
Parachordodes is a genus of worms belonging to the family Chordodidae.
Paragordionus is a genus of worms belonging to the family Chordodidae.
Paragordius is a genus of worms belonging to the family Chordodidae. It was independently described by both Lorenzo Camerano in 1897 and Thomas Harrison Montgomery Jr. in 1898, though both authors gave the genus the same name.
Neochordodes is a genus of worms belonging to the family Chordodidae.
Beatogordius is a genus of worms belonging to the family Chordodidae.
Pseudochordodes is a genus of worms belonging to the family Chordodidae.
Oregodasys is a genus of worms belonging to the family Thaumastodermatidae.
Diplodasys is a genus of worms belonging to the family Thaumastodermatidae.
