Bursaphelenchus decraemerae n. sp. (Tylenchina: Aphelenchoididae) found in packaging wood from the USA

Abstract

Bursaphelenchus decraemeraen. sp., isolated in Ningbo, China, from packaging wood made ofPinussp. imported from the USA, is described. It is characterised by the lateral field with three lines, a stylet 10-12 μm long with small basal swellings, excretory pore located 4-12 μm posterior to median bulb, spicule small, ventrally arcuate with lamina gradually tapering to distal tip, rostrum triangular pointed to conical, condylus elongated with bluntly rounded tip, and cucullus minute, barely visible. There are seven caudal papillae arranged as a single ventral precloacal papilla, one adcloacal pair and two postcloacal pairs. The bursal flap is narrow and oval. A small vulval flap is present in lateral view of the female and the tail is conical, strongly ventrally curved with the terminus finely pointed and sometimes appearing like a mucron. The new species is characterised by morphological and molecular analysis and is close toB. gerberaeandB. sakishimanus.
