Taxonomic of One New Record Species of Criconematoidea from China
摘要
Abstract
Criconematoidea were a class of parasitic nematodes with ring-type esophagus,extra-root parasitism(a few semi-parasitic)plants,with a particularly wide range of hosts,mainly living around the roots of crops and woody plants.In this study,a new record species of Criconematoidea was isolated from privet rhizosphere soil in Hangzhou Zhejiang province,China.The morphological characteristics of the nematode were identified by optical microscopy.The results showed that the isolated nematode was identified as Hemicriconemoides phoenicis,a new record species in China.The body length of female Hemicriconemoides phoenicis is 501.2(439.2-519.6)μm,has a ring-shaped esophagus,two lip rings,and its knobs anchor-shaped 82.3(79.8-85.2)μm long,spermatocyst is oval and filled with rounded sperm cells,a tail of 29.8(28.4-32.7)μm long.The juvenile is similar to the female.The male has not been seen.The maximum Likelihood method was used to construct a phylogenetic tree for the 18S rRNA gene of this nematode.The results showed that the isolated nematode were located on the branch of H.phoenicis(MN660076)cluster with the highest confidence(100%).H.phoenicis is a new record species reported for the first time in China.The date palm was the preferred host plant,but this study broadened the host range of H.phoenicis,suggesting that Ligustrum might also be its host plant.关键词
