Abstract Abomasal nematodes (Ostertagiinae: Trichostrongyloidea), representing a previously unrecognized genus and species, were discovered in kob (Kobus kob) and kongoni (hartebeest) (Alcelaphus buselaphus jacksoni) from Uganda during surveys of ungulate parasites in the 1960s. Robustostrongylus aferensis gen. nov. et sp. nov. is characterized by a ventriculus-like, bilobed valve at the junction of the esophagus and intestine, a synlophe with unusually robust ridges, cervical papillae and… 
Discovery and Description of a New Trichostrongyloid Species ( Nematoda : Ostertagiinaw ) , Abomasal Parasites in Mountain Goat , Oreamnos americanus , from the Western Cordillera of North America [ with erratum ]
TLDR
Shifting patterns of contact and sympatry among assemblages of ungulates during the Pleistocene are consistent with geographic and host colonization as a process involved in diversification of these parasites.
Synlophe Structure for Species of Longistrongylus (Nematoda: Trichostrongyloidea), Abomasal Parasites among Ungulates from Sub-Saharan Africa, with Comparisons to the Global Ostertagiine Fauna
TLDR
Among 5 of 6 species examined in the current study, the numbers of ridges in males was equal to or exceeded that observed in females, a pattern seen only in Africanastrongylus among the 15 genera of the Ostertagiinae.
Synlophe Structure in Pseudomarshallagia elongata (Nematoda: Trichostrongyloidea), Abomasal Parasites Among Ethiopian Ungulates, with Consideration of Other Morphological Attributes and Differentiation Within the Ostertagiinae
Abstract The independence of Pseudomarshallagia and its placement among the medium stomach worms of ungulates, Ostertagiinae, is confirmed based on comparative morphological studies of the synlophe
Discovery and Description of a New Trichostrongyloid Species (Nematoda: Ostertagiinae), Abomasal Parasites in Mountain Goat, Oreamnos americanus, from the Western Cordillera of North America
TLDR
Marshallagia lichtenfelsi is endemic to North America and limited in host distribution to mountain goats, and an intricate history for refugial isolation and population fragmentation demonstrated for mountain goats and wild sheep indicates the potential for considerable cryptic diversity for Marshallagia and other nematodes.
A New Species of Trichostrongyloid in African Buffalo (Syncerus caffer) (Artiodactyla: Bovinae) from Uganda
Abstract Africanastrongylus giganticus n. sp. is described based on large ostertagiine nematodes occurring in the abomasum of African buffalo, Syncerus caffer, from Uganda; this represents the second
Insight into species diversity of the Trichostrongylidae Leiper, 1912 (Nematoda: Strongylida) in ruminants
TLDR
The data presented here show that the members of the Trichostrongylidae can significantly complicate unambiguous species identification, and it is essential to consider the phenomena mentioned, to gather valid and comparable data on the biodiversity of this family.
Discovery and Description of the “Davtiani” Morphotype for Teladorsagia boreoarcticus (Trichostrongyloidea: Ostertagiinae) Abomasal Parasites In Muskoxen, Ovibos moschatus, and Caribou, Rangifer tarandus, from the North American Arctic: Implications for Parasite Faunal Diversity
TLDR
Collection to explore helminth diversity among free-ranging ungulates in the North American Arctic revealed the occurrence of a third male, or “davtiani,” morphotype for Teladorsagia boreoarcticus, which differs from conspecific morphotypes in the structure of the genital cone and Sjöberg's organ.

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.
ASHWORTHIUS PATRICIAPILITTAE N. SP. (TRICHOSTRONGYLOIDEA: HAEMONCHINAE), AN ABOMASAL NEMATODE IN ODOCOILEUS VIRGINIANUS FROM COSTA RICA, AND A NEW RECORD FOR SPECIES OF THE GENUS IN THE WESTERN HEMISPHERE
TLDR
The discovery of A. patriciapilittae emphasizes the continued need for survey and inventory to define the structure and distribution of parasite faunas in wild and domestic ruminants from the Nearctic and Neotropical regions.
Hamulonema Gen. Nov. for Teladorsagia hamata and OStertagia kenyensis in the Ostertagiine Fauna (Nematoda: Trichostrongyloidea) From African Ungulates
Hamulonema gen. nov. is proposed for Teladorsagia hamata and Ostertagia kenyensis in the ostertagiine nematode fauna found in artiodactyl hosts from Africa. Monomorphic species representing this
The taxonomic position of the nematode species Pseudomarshallagia thalae (Troncy and Graber, 1973) Graber and Delavenay, 1978 (family trichostrongylidae)
TLDR
Pseudomarshallagia thalae is nearest to the species Longistrongylus banagiense (Gibbons, 1972) Gibbons, 1977 but can be separated from it by differences in the sclerotization of the spicules, the shape of the proximal end of the Spicule, the slightly longer branches at the distalend of the dorsal ray and the larger accessory bursal membrane.
EMENDED DESCRIPTION AND REDETERMINATION OF SARWARIA CABALLEROI N. COMB. (NEMATODA: OSTERTAGIINAE) WITH DETAILS OF THE SYNLOPHE AND ESOPHAGEAL CHARACTERS
TLDR
It is proposed that the ostertagiines are represented by 12 valid genera, including those characterized by a bursal formula of 2-2-1, and those in which the lateral rays describe a 2-1-2 pattern.
SYNLOPHE PATTERNS OF THE HAEMONCHINAE OF RUMINANTS (NEMATODA: TRICHOSTRONGYLOIDEA)
TLDR
In the process of studying Mecistocirrus digitatus, the large stomach worm of bovids of Asia that has been imported and established in the Americas, remarkably similar synlophe patterns to those described for 3 species of Haemonchus and to those examined in a species of Ashworthius are observed.
Synlophe of Cooperia neitzi (Trichostrongylidae: Cooperiinae) with comments on vulval inflations and hypertrophy of cuticular ridges among the trichostrongylids
TLDR
It is suggested that vulval inflations in the Cooperiinae and Ostertagiinae had independent origins and thus are convergent, and the irregular and asymmetrical cuticular inflations reported or observed at the level of the vulva among certain Ostertaginae have a fundamentally different configuration.
PHYLOGENY FOR SPECIES OF HAEMONCHUS (NEMATODA: TRICHOSTRONGYLOIDEA): CONSIDERATIONS OF THEIR EVOLUTIONARY HISTORY AND GLOBAL BIOGEOGRAPHY AMONG CAMELIDAE AND PECORA (ARTIODACTYLA)
TLDR
Phylogenetic analysis of 25 morphological characters among the 12 species of Haemonchus resulted in 1 most parsimonious tree, which emphasizes the importance of continued documentation of faunal diversity in the context of predictive foundations derived from phylogenetic studies.
[A new classification of Trichostrongyloidea nematodes (author's transl)].
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.
Phylogenetic systematic analysis of the Trichostrongylidae (Nematoda), with an initial assessment of coevolution and biogeography.
TLDR
Assessment of host associations suggests extensive colonization but also a high degree of coevolution with Bovidae and Cervidae for Ostertagiinae+Haemonchinae; and biogeography for this assemblage is complex, but this analysis is compatible with a Palearctic or Eurasian origin.
