Oligacanthorhynchida is an order containing a single parasitic worm family, Oligacanthorhynchidae,[1] that attach themselves to the intestinal wall of terrestrial vertebrates.
Taxonomy and description[edit]
| Archiacanthocephala |
| Phylogenetic reconstruction for select species in the class Archiacanthocephala based on a 28S rRNA gene comparison from Gomes et. al (2019) and a 18S rDNA gene comparison from Amin et al. (2020).[2][3] Amin et al. (2022) used the 18S rDNA gene and ITS1-5.8-ITS2 region of ribosomal RNA comparisons to add P. canicola phylogenetically to the family Oligacanthorhynchidae.[3] |
Genera[edit]
Oligacanthorhynchida contains twelve genera and numerous species.[4][5][a]
Cucullanorhynchus[edit]
The genus Cucullanorhynchus Amin, Ha and Heckmann, 2008 is named for the anterior hood.[6] It was described in 2008 based on samples collected from the intestines of mammals between 1998 and 2004 in Vietnam.[6] C. constrictruncatus Amin, Ha and Heckmann, 2008 is the only species in the genus Cucullanorhynchus. It has been found in the intestine of the leopard (Panthera pardus) in Vietnam. The trunk has an anterior hood in both sexes and a posterior constriction in females. The species name derives from this constriction near the posterior end of females.[6]
Heptamegacanthus[edit]
The genus Heptamegacanthus Spencer-Jones, 1990 contains 1 species. Heptamegacanthus niekerki Spencer-Jones, 1990[7] H. niekerki is a parasite of the giant golden mole (Chrysospalax trevelyani) found in South-East Africa.[7]

Oligacanthorhynchus[edit]
The genus Oligacanthorhynchus Travassos, 1915 contains numerous species. The trunk is cylindrical and smooth or irregularly ringed. The proboscis is generally globular being somewhat longer than it is wide and has stout hooks in left handed spiral rows, with their point obliquely cut and their root produced forwards. The proboscis receptacle consists of a thick inner wall i inserted into inside of proboscis which is shrinks along the ventral side, and a thinner outer wall inserted at base of neck. A series of intercommunicating spaces branching from two median main vessels and numerous longitudinal and circular anastomoses in the hypodermis form the lacunar system. Protonephridia are present. The lemnisci are filiform with a central canal and numerous nuclei. In the far posterior of the male, there are testes and eight cement glands used to temporarily close the posterior end of the female after copulation.[10][11][12] The eggs are almost spherical with shells that are radially striated. Hosts include birds with snakes being the intermediate hosts.[12]

Pachysentis[edit]
The genus Pachysentis Meyer, 1931 contains ten species.[15] Generally, they look identical to Oncicola apart from the number of hooks on the proboscis. Species of Oncicola have 36 or less hooks whereas species of Pachysentis have more. Specifically, the proboscis is not quite spherical and contains 42 to 102 hooks arranged into 12 longitudinal rows 3 to 12 hooks each. The rows may be regularly or irregularly alternating and straight or crooked. Hooks have tips with or without barbs, and the larger hooks with complex manubria and roots with the remaining spines being rootless. The trunk is fairly wide relative to the length with the anterior half usually wider than the posterior half. The testes are in tandem with at least one located before the middle of the worm. There are eight cement glands compactly arranged each with single giant nucleus used to temporarily close the posterior end of the female after copulation.[10][11] The eggs have a sculptured outer membrane. Hosts include Brazilian or Egyptian carnivores.[12] Species can be distinguished based on the number and arrangements of proboscis hooks, whether these hooks are barbed, the arrangement of the cement glands, host, and the length of lemnisci.[2]

They have simple hook roots without manubria, and a large oblong horizontally posterior hook base. There are about 35 festoons. Protonephridia are gill-like and capsular. Gonopore is terminal. The primary host are Manidae in Vietnam with ants and termites as intermediate hosts. This genus is named for its nearest oligacanthorhynchid genus, Prosthenorchis.[6]
- Paraprosthenorchis ornatus Amin, Ha and Heckmann, 2008
P. ornatus has been found in the intestine of the Chinese pangolin (Manis pentadactyla) collected from the Hanoi Zoological Park, Vietnam. The anterior trunk has many small festoons and proboscis hooks are inserted in elevated papillae separated by beady, near hexagonal, ornate grids. The species is named for its uniquely ornate proboscis.[6]
Prosthenorchis[edit]
Prosthenorchis Travassos, 1915 have a trunk up to 50 mm long, a proboscis that is not ornate with three barbed hooks in each of 12 rows. They have complex hook roots with large manubria, and a small discoid posterior hook base. There are up to 23 festoons. Gonopore is subterminal. The primary host are primates in South America and Felidae in Africa with cockroaches and beetles as intermediate hosts.[6]

Oligacanthorhynchidae species parasitize mammals with insect and lizard intermediate hosts.
