Taxonomy
editThe species was described by Martin & Multani in 1966. The National Center for Biotechnology Information does not indicate that any phylogenetic analysis has been published on Microsentis that would confirm its position as a unique order in the family Neoechinorhynchidae.[2]
Description
editMicrosentis wardae consists of a proboscis covered in hooks and a long trunk.
Distribution
editThe distribution of M. wardae is determined by that of its hosts. They are found in Northern America.[1]

Hosts
edit
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 Microsentis are ???. 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. The final stage is the infective cystacanth which is the larval or juvenile state of an Acanthocephalan, differing from the adult only in size and stage of sexual development. The cystacanths within the intermediate hosts are consumed by the definitive host, usually attaching to the walls of the intestines, and as adults they reproduce sexually in the intestines. The acanthor is passed in the feces of the definitive host and the cycle repeats. There may be paratenic hosts (hosts where parasites infest but do not undergo larval development or sexual reproduction) for Microsentis.[5]
M. wardae parasitizes animals. There are no reported cases of M. wardae infesting humans in the English language medical literature.[4]
