Filisoma
genus of worms
Filisoma is a genus in Acanthocephala (thorny-headed worms, also known as spiny-headed worms).
Taxonomy
The genus was described by Van Cleave in 1928. The National Center for Biotechnology Information indicates phylogenetic analysis has been published on any Filisoma species.
Description
Filisoma species consist of a proboscis covered in hooks and a trunk.

Distribution
The distribution of Filisoma is determined by that of its hosts.
Hosts
The life cycle of an acanthocephalan consists of three stages beginning when an infective acanthor (development of an egg) is released from the intestines of the definitive host and then ingested by an arthropod, the intermediate host. Although the intermediate hosts of Filisoma are arthropods. When the acanthor molts, the second stage called the acanthella begins. This stage involves penetrating the wall of the mesenteron or the intestine of the intermediate host and growing.
Begin with the source’s own compact description: “Filisoma” is genus of worms. The dossier treats that line as a proposition to test through Filisoma, genus and worms, not as a finished interpretation.
Why this record matters
The phrase “genus of worms” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 18, 2026. The linked authority identifier is Q2105446. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1928, 1993, 2021 and 1988.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
