Currently, three Meloidogyne spp. are present on the quarantine A2 list of EPPO, M. chitwoodi, M. fallax and M. enterolobii. As a quarantine organism, M. fallax has been detected in England and Northern Ireland on sport turf in 2011, and in England on leek in 2013. However, its presence in Ireland has probably been overlooked since 1965, when Mr. John F. Moore and Dr. Mary T. Franklin had detected a new Meloidogyne species for that time. While the relevant data was recorded and a preliminary manuscript describing the species was prepared but never submitted for publication, and together with the original slides, pictures and drawings, it was restudied recently. We compared the population of Irish Meloidogyne sp. to other similar Meloidogyne spp. Careful observation and comparison shows that it belongs to M. fallax. The characters found to be common for Irish Meloidogyne sp. and M. fallax are female stylet length (14.6 mu m) with oval to rounded basal knobs, oval shaped perineal pattern with moderately high dorsal arch, slender stylet in males (18.5 mu m) with set off and rounded basal knobs, slightly set off male head with one post-labial annule and incomplete transverse incisures, and second-stage juveniles with large and rounded stylet basal knobs, and a gradually tapering tail (46.9 mu m) with a broadly rounded tip and a clearly delimitated smooth hyaline part sometimes marked by constrictions (12.9 mu m). The host test and gall formation also correspond to M. fallax. The identification could not be additionally supported by molecular analysis, as we were unable to extract DNA from the old permanent slides. Nevertheless, our study reveals that the Meloidogyne species detected in Ireland in 1965 belongs to M. fallax.}, isbn = {1313-2989}, author = {Topalovi{\'c}, O. and Moore, J.

A large quantity of an unknown stem nematode was isolated from the hulls and seeds of peanuts, herein described as Ditylenchus arachis n. sp. The new species is characterized by a combination of the following features: lateral lip sectors distinctly projected, stylet delicate, 84-10m in length, six lines in the lateral field, tail elongate-conoid, bursa covering about 68-86\% of tail length. Pathogenicity tests showed that D.arachis n. sp. could infect peanut (Arachis hypogaea), but not sweet potato (Ipomoea batatas) or potato (Solanum tuberosum). Morphologically, D.arachis n. sp. appears closest to D.africanus, D.myceliophagus and D.destructor, but can be differentiated based upon a combination of morphological characteristics, host preference and molecular sequence data. The results of the phylogenetic analysis, based on 18S rDNA, the D2-D3 expansion region of 28S rDNA, and the ITS1-58S-ITS2 region, confirmed its status as a new species. A sister relationship with D.destructor was appointed, rather than with its ecologically very similar congener D.africanus.}, keywords = {1945 TYLENCHIDA ANGUINIDAE, AFRICANUS, DESTRUCTOR THORNE, DIAGNOSTICS, GENE, groundnut, histopathology, INTERNAL TRANSCRIBED SPACER, MIXED MODELS, molecular, morphology, pathogenicity, ribosomal DNA sequencing, RIBOSOMAL-RNA, SEQUENCES, SOIL, SURVIVAL}, isbn = {0032-0862}, author = {Zhang, S.
