Bursaphelenchus paracorneolus sp. nov. (Nematoda, Parasitaphelenchidae) from coniferous wood in Germany and remarks on its biology and distribution. Bursaphelenchus paracorneolus sp. nov. was found in spruce and pine wood within the Bavarian Forest and near Potsdam in Germany. The new species is of medium size, females and males averaging 665 µm and 610 µm in length, respectively. It is characterized by an a-value of 28 and a mean stylet length of 13 µm. The lateral field shows 3 lines. The female tail is ventrally curved, tapering gradually to the end and has sometimes a mucro. The relatively stout paired spicules measuring 13-15 µm have a relatively blunt rostrum and a prominent cucullus. One postanal pair, one adanal pair of caudal papillae and a single papilla in front of the anus are present. A short bursa, best seen in dorsoventral view, surrounds the end of the male tail. The new species can easily be multiplied on Botrytis cinerea on malt agar. It was also found in larch wood imported from Irkutsk, Russia. Inoculation tests with B. paracorneolus sp. nov. onto Picea abies and Pinus sylvestris in a climate chamber at 25°C have shown that this species is not pathogenic.
