Davies, K.Giblin-Davis, R.Ye, W.Taylor, G.Makinson, J.Purcell, M.2015-06-112015-06-112014Zootaxa, 2014; 3889(2):237-2581175-53261175-5334http://hdl.handle.net/2440/92081Three new species of Fergusobia, respectively collected from shoot bud galls on narrow-leaved Melaleuca spp. in Australia, are described. Fergusobia armillarisae n. sp. Davies is characterised by the combination of an arcuate to open C-shaped parthenogenetic female with an extensile uterus and a short, conoid tail, an arcuate infective female with a broadly rounded tail tip, and an arcuate male with an angular spicule and bursa arising at 50-80% of body length. Fergusobia decorae n. sp. Davies has an arcuate parthenogenetic female with a non-extensile uterus and a broadly conoid tail, an arcuate infective female with most curvature behind the vulva and a short tail with a broadly rounded tip, and an arcuate male with an arcuate spicule and bursa arising at 40-50% of body length. Fergusobia linariifoliae n. sp. Davies is characterised by the combination of an arcuate parthenogenetic female with an extensile uterus and a short, conoid tail with a bluntly rounded tip, a barely arcuate infective female with a broadly rounded tail tip, and an arcuate male with an angular spicule and bursa arising at 40-50% of body length. Earlier molecular analyses inferred from DNA sequencing of 28S rDNA D2/D3 domains and a portion of mitochondrial DNA cytochrome oxidase subunit I (mtCOI) are further discussed.enCopyright © 2014 Magnolia PressMyrtaceae; galls; Neotylenchidae; Fergusonina; morphology; taxonomy; DNA sequencing; molecular phylogenyJournal article003001713010.11646/zootaxa.3889.2.40003467432000042-s2.0-84913604144163406Taylor, G.
