Two new species of Longidoridae are described from poorly growing date palms in Saudi Arabia. Longidorus orientalis n. sp., found in Dirab and Riyadh, (and also in soil around roots of grapevine in several localities in Iraq) is characterized by round, continuous lip region, bilobed amphids and hemispherical female tail, body length of 4-6 mm and odontostyle length of 96-113 μm. L. taniwha apud About-Eid, 1970 from Egypt is possibly identical with it. Xiphinema phoenicis n. sp. closely… 
Description and molecular characterisation of Xiphinema herakliense n. sp. (Nematoda: Longidoridae) from wild and cultivated olives in Crete.
TLDR
The results of the phylogenetic analyses based on the sequences of the D2-D3 expansion regions of the 28S rRNA gene and ITS1 rRNA genes are supportive of the specific status of the new species.
Genetic diversity, and description of a new dagger nematode, Xiphinema afratakhtehnsis sp. nov., (Dorylaimida: Longidoridae) in natural forests of southeastern Gorgan, northern Iran
The most prevalent dagger nematode recovered from rhizospheric soil samples of forest trees in the Afrātakhteh region of Golestan province (Iran) was Xiphinema afratakhtehnsis sp. nov. and it is
Observations on some species of Longidorus (Nematoda: Longidoridae) from Jiangsu Province, China, with a description of Longidorus jiangsuensis n.sp.
SUMMARY Four Longidorus species are reported from Jiangsu Province which are the first records of any species of this genus in China. One is described as L. jiangsuensis n. sp., characterized by the
Xiphinema bernardi n. sp. (Nematoda: Longidoridae) from the Great Smoky Mountain National Park.
TLDR
Molecular approaches using the internal transcribed spacer 1 sequences of nuclear ribosomal DNA suggested that X. bakeri and X. diversicaudatum are the most closely related species from the species examined.
Descriptions of three new longidorus species from alaska (nematoda: longidoridae).
TLDR
Three new Longidorus species are described from specimens collected near Fairbanks, Alaska, which most closely resembles L. alaskaensis n.
Characterisation of populations of Longidorus orientalis Loof, 1982 (Nematoda: Dorylaimida) from date palm (Phoenix dactylifera L.) in the USA and other countries and incongruence of phylogenies inferred from ITS1 rRNA and coxI genes
TLDR
Analysis of phylogenetic relationships of nematode populations revealed incongruence of the ITS1 rRNA and coxI mtDNA gene trees, which might be the result of selective introgression of mtDNA through gene flow between previously isolated populations introduced simultaneously into new geographical regions.
Morphological and molecular characterisation of Longidorus pauli (Nematoda: Longidoridae), first report from Greece
TLDR
Sampling for needle nematodes was carried out in a grapevine area in Thessaloniki, North Greece and two nematode species of Longidorus (L. pauli and L. pisi) were collected, extending the geographical distribution of this species in the Mediterranean Basin.
A revised polytomous key for the identification of species of the genus Xiphinema Cobb, 1913 (Nematoda: Longidoridae) with exclusion of the X. americanum-group
TLDR
A revised polytomous key to the 172 valid species (excluding the X. americanum-group) is presented and because of the very large number of species the key is split into eight groups on the basis of development of the anterior female genital branch, uterine differentiation and tail shape.
Integrative diagnosis and molecular phylogeny of dagger and needle nematodes of olives and grapevines in the island of Crete, Greece, with description of Xiphinema cretense n. sp. (Nematoda, Longidoridae)
TLDR
Molecular characterisation using D2-D3 expansion regions of 28S rRNA, 18S r RNA and ITS1-rRNA was carried out and maximum likelihood and Bayesian inference analysis were used to reconstruct phylogenetic relationships among these species and with other longidorids.
