چکیده
Summary Specimens of a thin longidorid species collected in Peñalba (Huesca), north-west Spain, were previously described as Paralongidorus iberis . However, we conclude, through scanning electron microscopy and molecular studies on population from about 15 km the type locality paratype specimens, that this was originally placed wrong genus. Both populations have pore-like amphidial apertures, not slit-like , is therefore transferred to Longidorus. Longidorus n. comb. regarded valid clearly different closely related such L. tabernensis iliturgiensis alvegus indalus morphometrics markers. Molecular data are reported for first time, including D2-D3 expansion segments 28S rRNA, ITS1 partial 18S rRNA mitochondrial coxI regions. These markers used inferring phylogenetic relationships with other within all separating taxa placing clade, rather than

A new needle nematode, Longidorus carniolensissp. n., recovered from the soil around the roots of grapevine Vitis vinifera L. from Slovenia, is described and illustrated. Longidorus carniolensisis an amphimictic species, characterised by females with a moderately long (L=5.6-8.2 mm) and plump (a=51-72.4, ave. 66.3) body, assuming a spiral to C-shape when heat relaxed.

متن کاملLongidorus breviannulatus n. sp. (Nematoda: Longidoridae) Associated with Stunted Corn in Iowa.
Longidorus breviannulatus n. sp. was associated with stunted corn in Iowa. The nematode has wide bilobed amphidial pouches, a guiding ring 21-26 mum from the anterior end of the body, an odontostyle 81-88 mum long, and a spear extension 28-45 mum long. The most frequent collections and the greatest numbers of the nematode in the field occurred in sandy soils. Nematodes increased in greenhouse c...

In a survey of ecotypes for longidorids, primarily from the rhizosphere hardwood trees growing in sandy soil along stream banks, 828 soil samples were collected from 37 Arkansas counties in 1999-2001. Eight populations of Longidorus breviannulatus were identified from the Arkansas survey samples. A total of 19 populations from California, Illinois, Iowa, Kansas, Michigan, Nebraska, New Jersey, ...

Longidorus crassus is a common species and widely distributed in Arkansas. It was also identified for the first time in samples from Alabama, Iowa, Kansas, Nebraska, South Carolina, Wisconsin, and Canada. It is a parthenogenetic species, but a few males were found and were described herein for the first time. Four developmental juvenile stages were identified. A high degree of intraspecies vari...
