Abstract: The present review has documented a list of keys for identifying plant-parasitic nematodes at different taxonomic levels including superfamily, family, subfamily, genus, and species. It was compiled as a current source of information to assist students and professionals in the discipline of nematology for identification of this important group of soil nematodes.

 

Keywords: Compendium, identification key, Longidoridae, Trichodoridae.

 

 

Introduction

 

While working on plant-parasitic nematodes, taxonomists have been documenting several identification keys on this group of nematodes. Although the work by Lewis et al. (1999) can be regarded as a very good documentation including a list of keys and references for identifying species of selected genera of plant-parasitic nematodes, it doesn’t cover a large part of current information provided in the literature.

For having a view on classification and general identification of plant-parasitic nematodes, readers may find very helpful the following general references beside of identification keys documented in the present paper: May & Lyon (1975), Ebsary (1991), Nickle (1991), Siddiqi (2000), Andrássy (2007), Hodda (2011), and Manzanilla-López & Marbán-Mendoza (2012). The landmark collection of papers on reappraisal of Tylenchina published in Revue de Nématologie during 1987 and 1988, is also highly recommended to obtain an excellent insight on the systematics of plant-parasitic nematodes.

In the present paper, nomenclature and systematics follow that of De Ley & Blaxter (2002, 2004) and Kashi & Karegar (2018) with slight modification. We have tried that the present work to be a comprehensive reference for identification keys to plant-parasitic nematodes; however, some works may be overlooked and thus not included in the list. Keys for identifying plant-parasitic nematodes at different taxonomic levels including superfamily, family, subfamily, genus, and species level are referred. The number of treated taxa is mentioned whenever data (full paper) was available. Taxa are arranged alphabetically, and for each taxon, keys are written based on the order of the year of publication, from the newest to the oldest. Dichotomous keys are simply named ‘key’, and diagnostic compendiums or tabular keys as ‘compendium’ throughout the paper.
