Abstract
Aphelenchoides huntensissp. n. is described and illustrated from wood and bark samples of a dead scots pine in Kermanshah Province, western Iran. The new species has a body length of 507-673 μm (females) and 636-640 μm (males). The cuticle is weakly annulated with four lateral lines. Lip region offset. The stylet is 9.5 (9.0-10.0) μm long with small basal swellings. The excretory pore is locatedcaone body diam. posterior to the metacorpus valve. The spicules are large with the dorsal limb 37 or 38 μm long (n = 2), and have a prominent rostrum and rounded apex. The female tail is conical, the terminus having a complicated step-like projection, usually with many tiny nodular protuberances. The male tail bears six (2 + 2 + 2) caudal papillae and a well-developed mucron. The new species belongs to the Group 2 category ofAphelenchoidesspecies. Phylogenetic analysis based on the 18S and 28S D2-D3 regions of rDNA confirmed its status as a new species.
