Guidelines for species descriptions of free-living aquatic nematodes: characters, measurements and their presentation in taxonomic publications Open
Free-living aquatic nematodes are abundant, diverse and of general environmental importance. However, knowledge of species distributions of both marine and freshwater nematodes is sparse. Species distribution data are crucial for evaluatin…

Scientific data and background behind the first detection of Meloidogyne enterolobii in Australia Open
The parasitic guava root-knot nematode, Meloidogyne enterolobii Yang and Eisenback (syn. M. mayaguensis ) , has a wide distribution, host range and is established majorly in tropical-subtropical climates. A routine diagnostic analysis of s…

DNA barcoding of Australian cereal cyst nematode populations with comments on likely origin and taxonomy (Tylenchoidea: Heterodera) Open
A species of Heterodera has been known to parasitise cereals in Australia since the 1930s. It caused significant yield losses across Australia’s cereal growing regions until resistance breeding largely brought it under control, although it…

Detection of heterodera mani in Western Australia Open
The ryegrass cyst nematode, Heterodera mani , is reported from Western Australia for the first time. Cysts were recovered from soil samples collected on a broadacre cropping property near the town of Esperance. The production area is domin…

First Records of Male and Swollen Females of Two Species of Achlysiella (Nematoda: Pratylenchidae) Open
Males and swollen mature females of Achlysiella trilineata and Achlysiella magniglans were discovered for the first time in Australia. These life stages confirmed that both species show well-marked sexual dimorphism in the anterior region …

Geographic range extension of hop cyst nematode, Heterodera humuli, from Tasmania to the Australian mainland Open
Hop cyst nematode, Heterodera humuli Filipjev, 1934 was found in soil samples collected from hop farms in Bushy Park, Tasmania and in Merriang, Victoria, Australia. Morphological and molecular characteristics were consistent with those des…

Phylogenetic position of Ptychaphelenchus eucalypticola Hodda, 2009 within the Aphelenchoidoidea Skarbilovich, 1947 (Siddiqi, 1980) inferred from partial 18S and 28S rDNA gene sequences Open
Summary At the time of description, the morphology of Ptychaphelenchus eucalypticola Hodda, 2009 indicated it could be assigned to either the Aphelenchoididae Skarbilovich, 1947 (Paramonov, 1953) or the Parasitaphelenchidae Ruehm, 1956 (Si…

Phylum Nematoda: feeding habits for all valid genera using a new, universal scheme encompassing the entire phylum, with descriptions of morphological characteristics of the stoma, a key, and discussion of the evidence for trophic relationships Open
This paper details a system for classifying the trophic relationships of the entire Phylum Nematoda, together with a table specifying the categories of every valid genus. This system encompasses both the diets of nematodes and how the food…

Reliability and Utility of Standard Gene Sequence Barcodes for the Identification and Differentiation of Cyst Nematodes of the Genus <i>Heterodera</i> Open
Difficulties inherent in the morphological identification of cyst nematodes of the genus Heterodera Schmidt, 1871, an important lineage of plant parasites, has led to broad adoption of molecular methods for diagnosing and differentiating s…

Potential distribution and biosecurity risks from three economically important plant‐parasitic nematodes Open
The plant‐parasitic nematodes (PPNs), Heterodera zeae , Hirschmanniella oryzae and Meloidogyne graminicola , are economically important pests of major grain crops. Each of these species is still absent from the majority of countries, so th…
