Morphological and molecular characterization of Filenchus pseudodiscus n. sp. from east Golestan province, north Iran; with an updated phylogeny of Malenchus Andrássy, 1968 (Tylenchomorpha: Tylenchidae)

the present study, two populations of the family Tylenchidae were recovered from natural forests of Golestan province, north Iran. The first species appeared as being a new member of Filenchus, and the second species belonged to Malenchus gilanensis (Jalalinasab et al., 2019). Thus, the present study aims to (i) characterize the new species using both traditional and molecular criteria, and (ii) update the phylogeny of Malenchus by including M. gilanensis in the LSU tree.

Among marker genes, the ribosomal RNA (rRNA) genes are being used as the standard barcode for almost all animals and successfully resolved several groups in Nematoda (Bert et al., 2008; Holterman

An interesting rare tylenchid species, Antarctenchus urmiensis n. sp. (Tylenchomorpha; Psilenchidae) from Urmia Lake islands, northwest Iran, with a discussion on the taxonomy of related genera

The taxonomy and phylogeny of tylenchids have already been studied and revised by several authors (Bert et al., 2008; De Ley and Blaxter, 2002; Holterman et al., 2009; Panahandeh et al., 2019; Sturhan, 2012; Subbotin et al., 2006). Following the molecular phylogenetic study of De Ley and Blaxter (2002), the order Tylenchida Thorne, 1949 sensu Siddiqi (2000), together with the former order Aphelenchida Siddiqi, 1980, formed the infraorder Tylenchomorpha De Ley and Blaxter, 2002 within the order

Infected host responses across entomopathogenic nematode phylogeny

the host cadaver recovers infectivity and movement (Shapiro and Glazer, 1996; Shapiro and Lewis, 1999; Shapiro-Ilan et al., 2003). This study uses a phylogenetic framework to assess how responsiveness to macerate from an EPN-infected insect, which contains both general host cues and species-specific pheromones, varies across four EPN species with increasing phylogenetic distance from a fifth “reference” species, Heterorhabditis bacteriophora. We used a 2016 phylogeny (Spiridonov and Subbotin, 2016

Both species were detected in galleries of Scolytus multistriatus (Marsham, 1802), a bark beetle that is known to transmit Dutch elm disease (DED).

Improved 18S small subunit rDNA primers for problematic nematode amplification

The 18S small subunit (SSU) ribosomal DNA sequence is one of the most useful molecular loci for identification and phylogeny reconstruction of agriculturally important nematodes. Various pairs of universal primers have been developed in the past to amplify short and long nematode sequences. However, certain nematode taxa were not readily amplified and/or sequenced with the existing primer tools. Frequently, the center region of a roughly 1,000 nucleotide segment would be lost. Therefore new
