Part III covers species with female stylet length >41 microm which are considered by this author to comprise the genus Gracilacus Raski, 1962. Seven new species of Gracilacus are described and further observations given on 14 other species. Paratylenchus strenzkei (Volz, 1951) Oostenbrink, 1960 is transferred to species inquirendae. A key to the species of Gracilacus is included. 
The genera Paratylenchus micoletzky - 1922 and Gracilacus raski - 1962 in Romania (Nematoda: Tylenchulidae)
Data on the occurrence and distribution of five species of Paratylenchus: P. curvitatus, P. microdorus, P. neoamblycephalus, P. nanus, P. projectus, and two species of Gracilacus: G. acicula and G.Expand
Gracilacus elongata n.sp. (Nemata: Criconematoidea) parasitic on Juncus ensifolius Wikstr. from Mendocino, California
In Our studies of (Mendocino Geological Terraces) in Mendocino County, California, one soil sample from Juncus ensifolius Wikstr. collected in 1979 from Terrace 3 (300 thousand years old), containedExpand
Paratylenchus labiosus n.sp. (Nematoda: Paratylenchidae) from Canada
Females have short stylets 15 to 17 μm long and concave–conoid heads with large, rounded submedian dorsal and ventral lips which readily separate this species from most paratylenchids. Expand
Description of Paratylenchus (Gracilacus) straeleni (De Coninck, 1931) Oostenbrink, 1960 (Nematoda: Criconematoidea, Tylenchulidae) from hazelnut in Turkey and its comparison with other world populations
The morphological and molecular characterisation, phylogenetic analysis of examined population and comparison of variability of worldwide known populations of P. straeleni are presented. Expand
Occurrence of Paratylenchus labiosus Anderson & Kimpinski, 1977 (Nematoda: Tylenchulidae) in Iran, with discussion on the validity of the species
During a survey on the identification of plant-parasitic nematodes associated with walnut in Sanandej region (Kurdistan province, western Iran), a population of Paratylenchus labiosus was collectedExpand
Paratylenchus conicephalus sp. n. from Iran with notes on P. similis Khan, Prasad & Mathur, 1967 (Nematoda: Paratylenchinae)
During nematode surveys in Iran two Paratylenchus populations were found and two new species were described and figured from the rhizosphere of Artemisia aucheri Boiss. Expand
Description of Gracilacus paralatescens n. sp. (Nematoda:Paratylenchinae) found from the rhizosphere of Bamboo in Zhejiang, China.
The phylogenetic analysis based on 18S, D2-D3 of 28S and ITS regions of rDNA, the new species is clustered with Paratylenchid species having longer stylet length and is most similar to G. latescens. Expand
Morphology and molecular analysis of Paratylenchus nanjingensis n. sp. (Nematoda: Paratylenchinae) from the rhizosphere soil of Pinus massoniana in China
The internal transcribed spacer sequences of ribosomal RNA (ITS rRNA) gene of the new species were amplified and sequenced in this study and the phylogenetic relationships of thenew species with other Paratylenchus species using the ITS rRNA gene sequences are given. Expand
Some Pacific Criconematina (Nemata)
A new genus, Syro, is described in the subfamily Criconematinae for four species (three of them new) indigenous to New Guinea and three known species from tropical Africa. Expand
Morphological and Molecular Characterization of Gracilacus wuae n. sp. (Nematoda: Criconematoidea) Associated with Cow Parsnip (Heracleum maximum) in Ontario, Canada.
Phylogenetic studies using the rDNA small subunit 18S, large subunit 28S D2/D3, and internal transcribed spacer (ITS) sequences collectively provide evidence of a grouping with other Gracilacus and some species of Paratylenchus with stylet length of females longer than 41 µm deposited in GenBank.
