Phylogenetic systematisation and catalogue of paraphyletic "Rhabditidae" (Secernentea, Nematoda)
- W. Sudhaus
This contribution presents an alphabetical list of 38 genus taxa accepted for “Rhabditidae” along with their synonyms and a list of the valid species that have been described to date with synonyms…
Comparative and functional morphology of the buccal cavity of Diplogastrina (Nematoda) and a first outline of the phylogeny of this taxon
The morphological data were used to reconstruct a first outline of the phylogenetic relationships of the Dipolgastrina and shows that the transformation of the buccal cavity in Diplogastrina is linked with an expansion of ecological niches.
Ecology of Caenorhabditis species.
Data is presented on the habitat, animal associations, and geographical distribution of the eighteen described and five undescribed Caenorhabditis species currently known to science.
Rhabditis (Oscheius) Guentheri1 Sp.N., an Unusual Species With Reduced Posterior Ovary, With Observations On the Dolichura and Insectivora Groups (Nematoda: Rhabditidae)
The hermaphroditic species Rhabditis guentheri sp. n. from decaying tissue of rice plants in Vietnam is described, separated from previously described Rhabditis species by its more or less reduced…
A phylogenetic classification and catalogue of the Diplogastridae (Secernentea, Nematoda)
Comparative genomics of 10 new Caenorhabditis species
The whole-genome data are exploited to reconstruct the Caenorhabditis phylogeny and a phylogenetic tree is used to dissect the evolution of morphology in the genus, showing unexpected complexity in the evolutionary history of key developmental pathway genes.
One small step for worms, one giant leap for “Bauplan?” *
Comparison of the cryptic nematode species Caenorhabditis brenneri sp. n. and C. remanei (Nematoda: Rhabditidae) with the stem species pattern of the Caenorhabditis Elegans group
The new gonochoristic member of the Caenorhabditis Elegans group, C. brenneri sp. n., is described. This species is reproductively isolated at the postmating level from its sibling species, C.…
Description of Caenorhabditis japonica n. sp. (Nematoda: Rhabditida) associated with the burrower bug Parastrachia japonensis (Heteroptera: Cydnidae) in Japan
The species is closely related to species of the Caenorhabditis elegans group and shares many characters with them, but differs from these species in having blunt spicule tips of complex shape and in lacking a terminal notch in the bursa velum.
Phylogeny of Rhabditis subgenus Caenorhabditis (Rhabditidae, Nematoda)*
A phylogenetic analysis was conducted using morphological characters, finding that the markedly different ecological niches of these species must be derived from a way of life in the stem species in patchily distributed decomposing organic material which necessitated a phoretic phase with waving behaviour of the dauer juveniles.
