- Abstract
Summary: Deladenus taedae n. sp. was isolated from loblolly pine wood (Pinus taeda) intercepted in Ningbo, P.R. China, in imports from the USA. This new species is morphologically described and illustrated and characterised molecularly. Both mycetophagous and infective forms were recovered and described. The new species, D. taedae n. sp., resembles some other species of Deladenus in which the excretory pore is situated anterior to the hemizonid. The new species is characterised by the lateral fields with six lines, pointed tail ending and small spermatheca in mycetophagous females and short stylet in infective females. In mycetophagous females, the excretory pore is 74-98 μ m from the anterior end and 37-54 μ m anterior to the hemizonid. The partial rDNA 18S, complete internal transcribed spacer, 5.8S and partial 28S D2/D3 genes were amplified and sequenced. Phylogenetic analyses of the genes distinguished this new species from all other sequenced Deladenus species.
