Abstract: 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 Paralongidorus and Xiphinema. Among the 06 (six) genera that comprise the family of Longidoridae, 03 (three) occur in Senegal, including genera of Longidorus, Paralongidorus and Xiphinema. Species are distributed as it follows: one species of Longidorus (Longidorus pisi), four species of Paralongidorus (P. bullatus, P. dakarensis, P. duncani, and P. sivestris), and fourteen species of Xiphinema (X. 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). 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: Pennisetum and Sorghum (for species of Longidorus); Acacia, Agrotis, Andropogon, Arachis, Borreria, Combretum, Gossypium, Guiera Pennisetum, Sorghum (for Paralongorus species); Abelmoschus, Agrotis, Apium, Arachis, Borreria, Brassica, Citrullus, Citrus, Combretum, Gossypium, Guiera, Hibiscus, Hypochaeris, , Ipomoea, Nymphea, Oryza, Pandanus, Pennisetum, Solanum, Tridax, and Vigna (for Xiphinema species). Local keys identification characters include: body length and stylet length (for Paralongidorus species); genital branches shape, structure of labial region, structure of ovary, structure of uterus, structure of Z-Organ, tail length, and tail width (for Xiphinema species).
