An Entomopathogenic Nematode, Steinernema Monticolum Sp. N. (Rhabditida: Steinernematidae) From Korea With a Key To Other Species

Abstract

A nematode new to science, S. monticolum sp. n. (Rhabditida: Steinernematidae) found during a survey of entomopathogenic nematodes conducted throughout the nine provinces of Korea, is described. It can be separated from other members of the genus by the length of the tail mucro in adults of both generations, the shape and length of the male spicules and gubernaculum, and the arrangement of the genital papillae. The infective juvenile can be distinguished from other Steinernema species by the body width and the value of ratio a (total length divided by greatest width). An amendment of the specific name of several Steinernema species is presented. A key to the new and other Steinernema species is provided.
