Summary - This article begins with a critical review of the article of Lamberti et al. (1992) with descriptions of X. brevu:ollum, X. diffusum, and three new species (X. parvum, X. pseudoguirani, X. raylon), ail c10sely related to each other. After studying rype specimens of these five species and pararypes of X. incognirum and X. shen, the present authors propose X. diffusum, X. iruognitum, X. parvum, X. pseudoguirani, X. sheri, and X. taylori as junior synonyms of X. brevicollum. The second… 
The occurrence and geographic distribution of Xiphinema and Xiphidorus species (Nematoda: Longidoridae) in Brazil
A dichotomous key for the identification of Xiphinema species reported in Brazil is presented and several of these spe-cies are important economically as they are efficient vec-tors of several members of the genus Nepovirus that cause diseases in a wide range of fruit and vegetable crops.
Intra-specific variation of Xiphinema brevicolle Lordello et Costa, 1961 (Nematoda: Longidoridae) in Japan
This study was conducted using morphological characters of females and DNA sequences of the mitochondrial COI region and the nuclear ribosomal RNA regions (rDNA) to study intra-specific variations of the species.
Studies on some species of the Xiphinema americanum group (Nematoda, Dorylaimida) occurring in Florida
The study of the morphometrics of putative Xiphinema americanum group populations collected in various habitats in Florida, United States of America, revealed the presence of four species: X. floridae, X. citricolum and X. laevistriatum.
First report of Xiphinema brevicolle Lordello et Costa, 1961 (Nematoda, Longidoridae) in Japan
Abstract Mixed populations of Xiphinema americanum-group species were detected from a root zone soil sample of Japanese holly, Ilex crenata, during a survey for plant-parasitic nematodes of
An integrative approach to the study of Xiphinema brevicolle Lordello and Da Costa 1961, supports its limited distribution worldwide (Nematoda: Longidoridae)
By using a phylogenetic framework, molecular and morphometric data of the topotype population it is demonstrated that certain of the published DNA sequences have been misidentified and belong to closely related species such as X. taylori, X. diffusum or unknown/unidentified species.
Molecular and morphological characterisation of Xiphinema americanum-group species (Nematoda: Dorylaimida) from California, USA, and other regions, and co-evolution of bacteria from the genus Candidatus Xiphinematobacter with nematodes
Comparison of the bacterial 16S rRNA and nematode COI phylogenies revealed a high level of co-speciation events between host and symbiont and provided solid evidence for distinguishing 17 species of this genus based on the analysis of new and previously published sequences.
On five species of the genus Xiphinema Cobb , 1913 ( Nematoda : Longidoridae ) recently described from India
Examination of paratypes of five species of Xiphirzemn from India described by Singh and Khan (1998) led to the following conclusions: X. lnrlinni Khan & Singh, 1998 appears a valid species close to
Molecular characterization of Xiphinema brevicollum (Nematoda: Longidoridae) from the Czech Republic
Populations of Xiphinema brevicollum occurring in the Czech Republic were described morphologically and molecularly and comparison of cox1 sequences of X. taylori from the Slovak Republic suggested that these populations represent the same species.
Cryptic diversity and species delimitation in the Xiphinema americanum-group complex (Nematoda: Longidoridae) as inferred from morphometrics and molecular markers
Integrative taxonomy, based on a combination of multivariate morphological and molecular analyses constitutes a new insight into the identification of X. americanum-group species.
Distribution and morphometrical characterization of Xiphinema pachtaicum, X. simile and X. brevicollum from Hungary
The distribution of species of the Xiphinema americanumgroup in Hungary was studied by collecting 272 samples from 53 localities, finding three species: X. brevicollum, X. pachtaicum and X. simile.


On the systematics of eleven Xiphinema species (Nematoda: Longidoridae) described from India
SUMMARY ,Observations made on eleven Xiphinema species described from India have resulted in the authors confirming X. elitum Khan, Ghawla & Saha, 1978 as a valid species. X. neodimorphicaudatum
Three Xiphinema Species From Papua New Guinea and the Solomon Islands (Nematoda: Longidoridae)
The new species is compared with X. mammillatum S. ensiculiferum (Cobb, 1893) and can be distinguished, among other things, by the differently shaped and shorter tail, larger number of ventral and lateral body pores, and differences in tail shape in juvenile stages.
Plant Parasitic Nematodes From Bahia State, Brazil: the Genus Xiphinema Cobb, 1913 (Dorylaimoidea)
A review is given of the Xiphinema species occurring in the south-eastern part of Bahia, Brazil. Nine species were found, two of which are new: X. dimidiatum with mammillate tail, females are
The genus Xiphinema Cobb, 1913 (Nematoda : Longidoridae) in Peru
SUMMARY Fifty soil samples from various climatic zones in Peru yielded the following species : Xiphinema index, X. brusiliense, X. costaricense, X. paritaliae, X. setariae, and many populations
A dichotomous key for the identification of species of the genus Xiphinema within the X. americanum-group is proposed, based mainly on the length of the body and the odontostyle and on the value of ratios a, c, c' and V.
A report of some Xiphinema species occurring in Peru (Nematoda, Dorylaimida)
Eight species beloging to the genus Xiphinema Cobb are reported from Peru, with X. peruvianum seems to be widespread in the Lima area and probably represents an undescribed species.
Diversity of Xiphinema americanum-group Species and Hierarchical Cluster Analysis of Morphometrics.
Study of morphometrics of 49 populations, including the type populations of the 39 species attributed to this group, by principal component analysis and hierarchical cluster analysis placed the populations into five subgroups, proposed here as the X. americanum subgroup.
Variation Within the Xiphinema Americanum Group (Nematoda: Longidoridae)
The data suggest that shorter nematodes with smaller "a" ratios, a wider range of "c" ratios and stylet lengths, and lower vulva percentages are correlated with localities closer to the equator that have high amounts of precipitation and high mean temperatures.
Two new species of Xiphinema (Nematoda: Longidoridae) from British Columbia vineyards
