Longidorus brevis sp. n. (Nematoda : Longidoridae) from Senegal, West Africa

#Longidorus brevis sp. n. is described from the rhizosphere of #Guiera senegalensis, #Pennisetum pedicellatum, #Cordyla pinnata and #Blumea aurita in Senegal. It is a small longidorid, morphologically resembling #L. juveniloides, #L. juveniis, #L. reneyii and #L. laevicapitatus$. The new species can be distinguished from these species by combinations of the following characters : short, thick body (L = 1.71-2.13 mm and a = 54.2-69.9), short odontostyle (40-43 micrometers), lobed amphidial pouches, distance of guide ring from anterior end (23-25.5 micrometers) and an elongate conoid tail with a slightly digitated terminus (c' = 1.89-2.61).
