Caballerorhynchus is a monotypic genus of acanthocephalans (thorny-headed or spiny-headed parasitic worms) containing a single species, Caballerorhynchus lamothei, that infests animals.
Taxonomy[edit]
The species was described by Salgado-Maldonado in 1977.
Description[edit]
C. lamothei consists of a proboscis covered in hooks, a proboscis receptacle, and a long trunk.
Distribution[edit]
The distribution of C. lamothei is determined by that of its hosts.
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 Caballerorhynchus 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 are 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 Caballerorhynchus.[3]
C. lamothei parasitizes animals. There are no reported cases of C. lamothei infesting humans in the English language medical literature.[2]
