Compilation of Phytonematodes of the Family Longidoridae (Nematoda: Dorylaimida) from Senegal

Historically, this synthesis work on the Dorylaimida parasite of plants encountered in Senegal is the second of its kind. It is then a synoptic view that, through the scientific literature on the description of populations of phytonematode dorylaimides from Senegal, lists all species of Longidoridae from Senegal. The present work aims to: i) make an inventory of the Longidoridae nematofauna described in Senegal so far; ii) contribute to the knowledge of the geographic distribution of this nematofauna in Senegal as well as the host plants, iii) establish a simple local identification key for each of the genera <i>Paralongidorus</i> and <i>Xiphinema</i>. Among the 06 (six) genera that comprise the family of Longidoridae, 03 (three) occur in Senegal, including genera of <i>Longidorus</i>, <i>Paralongidorus</i> and <i>Xiphinema</i>. Species are distributed as it follows: one species of <i>Longidorus </i>(<i>Longidorus pisi</i>), four species of <i>Paralongidorus</i> (<i>P. bullatus</i>, <i>P. dakarensis</i>, <i>P. duncani</i>, and <i>P. sivestris</i>), and fourteen species of <i>Xiphinema </i>(<I>X.</I> <i>algeriense, X. americanum, X. basiri, X. bergeri, X. ebriense, X. elongatum, X. ifacolum, X. krugi, X. luci, X. mounporti, X. opisthohysterum, X. parasetariae, X. savanicola, X. setariae)</i>. Among the fourteen regions of Senegal, the presence of nematodes of the Longidoridae family has been reported in ten of them (Dakar, Diourbel, Fatick, Kaffrine, Kaolack, Kolda, Saint-Louis, Tambacounda, Thiès and Ziguinchor). The following genera of host plants are registered: <i>Pennisetum</i> and <i>Sorghum </i>(<i>for species of Longidorus</i>); <i>Acacia, Agrotis, Andropogon, Arachis</i>, <i>Borreria, Combretum</i>, <i>Gossypium</i>, <i>Guiera</i> <i>Pennisetum</i>, <i>Sorghum </i>(<i>for Paralongorus species</i>); <i>Abelmoschus</i>, <i>Agrotis, </i>Apium, <i>Arachis,</i> <i>Borreria, Brassica</i>, <i>Citrullus</i>, <i>Citrus</i>, <i>Combretum</i>, <i>Gossypium</i>, <i>Guiera, Hibiscus</i>, <i>Hypochaeris</i>, , <i>Ipomoea</i>, <i>Nymphea</i>, <i>Oryza</i>, <i>Pandanus</i>, <i>Pennisetum</i>, <i>Solanum</i>, <i>Tridax</i>, and <i>Vigna</i> (for <i>Xiphinema</i> species). Local keys identification characters include: body length and stylet length (for <i>Paralongidorus</i> species); genital branches shape, structure of labial region, structure of ovary, structure of uterus, structure of Z-Organ, tail length, and tail width (for <i>Xiphinema</i> species).
