Re-examination of Teladorsagia hamata (Mönnig, 1932) Durette-Desset, 1989 reported from grey rhebuck, Pelea capreolus (Forster, 1790) proved it to be a new species of Ostertagi Ransom, 1907. The new species, for which the name Ostertagia triquetra n. sp. is proposed, differs from Teladorsagia hamata in the configuration of the bursal rays (2-1-2 in the former, 2-2-1 in the latter), and in that the interno-dorsal branch of the spicules bears a process that is triangular and convex in the new…

An Exploration of Diversity Among the Ostertagiinae (Nematoda: Trichostrongyloidea) in Ungulates from Sub-Saharan Africa with a Proposal for a New Genus
TLDR
The diverse nature of the ostertagiine fauna, with a disproportionate number of endemic genera relative to other regions of the northern hemisphere, may reflect the timing of episodic expansion events for artiodactyls into Africa from Eurasia during the Tertiary and Quaternary.

TLDR
The total nematode burdens of the bontebok were considerably larger than those of the grey rhebuck and no clear pattern of seasonal abundance for the helminths of either host species was evident.

TLDR
It is believed that two families, Amidostomatidae and Strongylacanthidae evolved from ancestors close to the Ancylostomatoïdea, and the principal evolution of the group seems to have occurred during the Secondary Era in Gondwanaland.
Nomenclature proposée pour les espèces décrites dans la sous-famille des ostertagiinae Lopez-Neyra, 1947
The species of the subfamily Ostertagiinae are reclassified according to the following characters: bursal ray pattern (2-1-2 or 2-2-1), relative length of ribs, and synlophe. Six genera are
Helminth and arthropod parasites of vaal ribbok, Pelea capreolus, in the western Cape Province.
TLDR
Five vaal ribbok culled in the Bontebok National Park during December 1979, were examined for helminth and arthropod parasites and there was also evidence of previous infestation by the larvae of 2 oestrid flies.

The helminth parasites recovered from sheep, cattle, impala and blesbok during several surveys conducted in the Republic of South Africa are listed as definitive, occasional or accidental parasites
The distances between cuticular ridges follow a Gaussian function in ostertagiine nematodes: the potential use of this phenomenon as a taxonomic criterion
The distribution of distances between cuticular ridges was studied in six genera of ostertagiines. It was well fitted by a Gaussian function of the position of the inter-ridges on both the dorsal and
