Longidoroidea (Thorne, 1935) n. rank. (Nematoda: Dorylaimina) with the description of Xiphinema neoamericanum n.sp. from India and proposal of a new name for X. americanum sensu Carvalho (1956) non Cobb, 1913.

  author={S. H. Khan and S. Ahmad},
Longidorid nematodes are characterized by having a long and attenuated spear (odontostyle) and a long spear-extension (odontophore) which may have plain or flanged base. This type of feeding apparatus makes them a distinct group in the suborder Dorylaimina (de Man, 1876) Pears, 1936, but also makes it difficult readily to accomodate them in the superfamily Dorylaimoidea (de Man, 1876) Thorne, 1934. We, therefore, consider them to represent a distinct superfamily group and hence, the family… Expand
A revised polytomous key for the identification of species of the genus Xiphinema Cobb, 1913 (Nematoda: Longidoridae) with exclusion of the X. americanum-group
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. Expand
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 populationsExpand
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. Expand
Description of Xiphidorus achalae n. sp. and proposal for a classification of longidorids (Nematoda: Dorylaimoidea)
Proposition d'une classification emendee des longidorides avec une seule famille les Longidoridae, pas de sous-famille d'Argentine. Expand
Observations on some Xiphinema species found in Brazil (Nematoda: Dorylaimoidea).
The present paper reviews the biometrics and taxonomic status of X iphinema populations collected in 10 Brazilian States. Expand
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. Expand
A phylogenetic approach to the classification of the longidoridae (Nematoda: Dorylaimida)
Through out-group comparison and comparison of the five genera listed above, the characteristics of longidorid ancestry are established and the resulting cladogram is used as a basis for a new classification of the family. Expand
Records of species of Xiphinema Cobb from Peru are occasional and infrequent (Tarjan, 1969; Jatala, 1975; Lamberti and Bleve-Zacheo, 1979). In the nematode collection of the International PotatoExpand
On the identity of Xiphinema americanum in Chile with a key to the Xiphinema species occurring in Chile
It was concluded that X. americanum sensu stricto does not occur in Chile and the morphometric characters of the species of Xiphinema, so far found in Chile, are provided together with a key for their identification. Expand
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. Expand
