Abstract

Aphelenchoides parvus n. sp. is described and illustrated on the basis of morphological and morphometric characters. It was recovered from bark samples of a dead fallen pine tree (Pinus eldarica) in Tehran city. The new species is characterized mainly by a short body length of 307-375 µm, four lateral lines, rounded lip region, well set off from the body contour, short stylet 6-8 µm long with small basal swellings, secretory-excretory pore usually posterior to the median bulb, post-vulval uterine sac (PUS) 34-40 µm long, conical tail with broadly rounded tip bearing a very small mucro and absence of male. It belongs to the group 2 of the morphological intragenus grouping of the genus, by having mucronated tail. By having a small body size and mucronated tail, the new species is compared with the most relevant species, viz. A. absari, A. curiolis, A. eradicitus, A. lagenoferrus, A. minoris, A. neominoris, A. parabicaudatus and A. tuzeti.
