Such a life cycle involving water and land can improve energy flow in riparian ecosystems however, its temporal dynamics in nature have rarely been investigated. The life cycle of the freshwater horsehair worm typically includes a free-living phase (adult, egg, larva) and a multiple-host parasitic phase (aquatic paratenic host, terrestrial definitive host). PMID:28824281Īnnual Survey of Horsehair Worm Cysts in Northern Taiwan, with Notes on a Single Seasonal Infection Peak in Chironomid Larvae (Diptera: Chironomidae). formosanus, and may be attributed to the incomplete development of this particular individual. These five worms showed high degrees of similarity in COI sequences and morphology, but one of these individuals bore abnormal crowned areoles, which has never been observed in C. formosanus were observed emerging from an Acromantis mantid, and two long-horned grasshopper hosts (Leptoteratura sp.

Chordodes formosanus is another common horsehair worm species in Taiwan, which was previously believed to specifically parasitize Hierodula mantids. Despite the distinct differences in the post-cloacal crescents between 14 male samples, their conspecific status, along with that of nine female samples, was upheld by a phylogenetic comparison of partial cytochrome oxidase subunit I (COI) sequences. protectus with moderately flat areoles on its tail tips, but is distinguishable by small mid-body ornamentations. n., a redescription of Chordodes formosanus, and novel host records for the latter are provided. n., with a redescription of Chordodes formosanus and novel host records from Taiwan ( Nematomorpha, Gordiida)Ĭhiu, Ming-Chung Huang, Chin-Gi Wu, Wen-Jer Shiao, Shiuh-FengĪbstract A description of a new species of horsehair worm, Acutogordius taiwanensis sp. In addition, further specimens from the genera Gordius, Acutogordius and Chordodes could not be determined to species level.Ī new orthopteran-parasitizing horsehair worm, Acutogordius taiwanensis sp. Two species, Gordius jorriti and Acutogordius finni, are described as new species. We report here several records, almost all from Panay Island. With the exception of one species, no horsehair worms ( Nematomorpha) were known to date from the Philippines.
