Aligned 265-bp sequences of partial 18S rRNA gene were used to infer phylogenetic relationships among entomopathogenic nematodes by using maximum parsimony and likelihood methods. Phylogenetic analyses support Heterorhabditidae and Steinernematidae belonging to different monophylies. There was more sequence divergence in Steinernema species than in Heterorhabditis species. These results are congruent with the phylogenies based on morphological, life cycle, and distributional evidence… 
Phylogenetic relationships of Steinernema Travassos, 1927 (Nematoda: Cephalobina: Steinernematidae) based on nuclear, mitochondrial and morphological data
TLDR
Parsimony mapping of morphological characters on the 3-gene trees showed that most structural features of steinernematids are highly homoplastic, and the distribution of nematode foraging strategies on these trees predicts that S. hermaphroditum, S. diaprepesi and S. longicaudum have cruise forager behaviours.
Molecular differentiation and phylogeny of entomopathogenic nematodes (rhabditida: heterorhabditidae) based on ND4 gene sequences of Mitochondrial DNA.
TLDR
The molecular phylogeny of Heterorhabditis species support an existing taxonomy that is based largely on morphology and the sequence divergence of the ND4 gene permits species identification.
Phylogeny of Steinernema Travassos, 1927 (Cephalobina: Steinernematidae) Inferred From Ribosomal DNA Sequences and Morphological Characters
TLDR
Interpretation of morphological character evolution on 6 trees inferred from sequence data and combined evidence suggests that many structural features of these nematodes are highly homoplastic, and that some structures previously used to hypothesize relationships represent ancestral character states.
Phylogenetic relationships within the cyst-forming nematodes (Nematoda, Heteroderidae) based on analysis of sequences from the ITS regions of ribosomal DNA.
TLDR
ITS sequence data are appropriate for studies of relationships within the different species groups and less so for recovery of more ancient speciations within Heteroderidae.
Phylogeny of Meloidogyne spp. based on 18S rDNA and the intergenic region of mitochondrial DNA sequences
TLDR
The addition of taxa and mtDNA data to publicly available records improved the discrimination sensitivity of species and atypical, non-identified, isolates.
Phylogenetic relationships within the genus Steinernema (Nematoda: Rhabditida) as inferred from analyses of sequences of the ITS1-5.8S-ITS2 region of rDNA and morphological features
TLDR
The ITS rDNA data were found to be of little utility in resolving relationships between these clades, but were useful in studying relationships between species within certain clades.
Molecular identification, phylogeny and phylogeography of the entomopathogenic nematodes of the genus Heterorhabditis Poinar, 1976: a multigene approach
TLDR
Phylogenetic and sequence analysis of these genes using Bayesian inference, maximum likelihood and statistical parsimony confirmed a division of the genus into three clades (groups): ‘Indica’, ‘Bacteriophora’ and ‘Megidis’.
Intraspecific variations and phylogenetic relationships among heat tolerant strains of Steinernema siamkayai (Rhabditida: Steinernematidae) from Pakistan.
TLDR
The genetic diversity and phylogenetic intraspecific relationship among thirty heat tolerant strains of Steinernema siamkayai from Pakistan were investigated during summer season and the highest survival rate for heat tolerance was observed in PAK.
Assessing nuclear and mitochondrial DNA sequence variation within steinernema (rhabditida: steinernematidae).
TLDR
Phylogenetic analysis of both nuclear and mitochondrial DNA sequences confirms the existing morphological relationships of several Steinernema species and useful for resolving relationships among SteinERNema taxa.
Phylogenetic and population genetic studies on some insect and plant associated nematodes
TLDR
The results suggest that the HP88 group is most closely related to H. downesi K122 followed by H. marelatus Oregon, and the cox1 analysis suggested that HP88 is divided into two subgroups: the GPS11 group and the Oswego subgroup.

Phylogenetie analysis of the genus Steinernema by morphologieal eharaeters and randomly anlplified polymorphie DNA fragments (1)
TLDR
It is found that RAPD fragments were an effective means of differentiating species, but the divergence among species at this level was so great that these fragments may provide little information about the phylogenetic relationships among the species.

TLDR
Phylogenetic inference based on maximum-likelihood analysis of all sequence sites yielded a tree of topology similar to that of the parsimony result, and the inferred rate of rRNA sequence change along the branch leading to Parascaris equorum is not consistent with a clocklike model of evolution.
Advantages and disadvantages of molecular phylogenetics: a case study of ascaridoid nematodes.
TLDR
The topology of the maximum parsimony tree based on full-length sequences of 18S rRNA and 300 nucleotides of Cytochrome oxidase II for 13 ascaridoid species was generally consistent with traditional taxonomic expectations at lower ranks, but inconsistent with most proposed arrangements at higher taxonomic levels.
The phylogenetic status of arthropods, as inferred from 18S rRNA sequences.
TLDR
It is suggested that a previous study's inference of the Arthropoda as paraphyletic may be the result of having two few arthropod taxa available for analysis and including long-branched taxa, and that the evolutionary-parsimony method, like distance and parsimony, may be biased by taxa with long branches.
18S ribosomal RNA gene phylogeny for some Rhabditidae related to Caenorhabditis.
TLDR
18S rDNA sequences cannot be used to resolve relationships between taxa as closely related as the Caenorhabditis species, and Parsimony, minimum-evolution, and maximum-likelihood methods strongly reject Andrássy's proposed phylogenetic classification based on adult morphological characters but support that of Sudhaus as one of a few possible phylogenies.
Natural Distribution of Entomopathogenic Nematodes (Rhabditida: Heterorhabditidae and Steinernematidae) in Oregon Soils
To determine the natural distribution of entomopathogenic nematodes (Heterorhabditidae and Steinernematidae) in Oregon, 255 soil samples were taken from 59 sites representing ecologically diverse
Cloning of the rDNA repeat unit from a British entomopathogenic nematode (Steinernematidae) and its potential for species identification
TLDR
Three clones cloned as three separate EroR I fragments in the plasmid pUCl 8.0 can detect length heterogeneities in the rDNA repeat unit of various isolates of some of the species, particularly the most common in the United Kingdom, S. feltiae.
Phylogeny of 54 representative strains of species in the family Pasteurellaceae as determined by comparison of 16S rRNA sequences
TLDR
The results presented a clear picture of the phylogenetic relationships, the complexity of the branching will make division of the Pasteurellaceae family into genera a difficult and somewhat subjective task.
