- Abstract
Summary: Aphelenchoides medicagus n. sp. isolated in Ningbo Port, P.R. China, from dried leaves and shoots of Medicago sativa imported from the USA, is described. It is characterised by a lateral field with four lines (three bands), stylet 9.0-12.0 μ m long, excretory pore situated at same level as, or slightly posterior, to the nerve ring, vagina sclerotised, female vulval flap absent, post-uterine sac short, spicules 9.2-14.2 μ m long (median curved line), rosethorn-shaped, apex and rostrum rounded, poorly developed, female and male tail conical with terminus bearing star-like processes. The new species belongs to the Group 3 category of Aphelenchoides species sensu Shahina. Phylogenetic analyses based on 18S, ITS and 28S D2-D3 of rDNA and mtCOI sequences confirmed its status as a new species and closely related to A. besseyi and A. fujianensis.
