Abstract
During a survey of plant-parasitic nematodes in the central regions of Senegal, a new species of Paralongidorus and seven populations of P. bullatus were collected. Paralongidorus dakarensis sp. n. is characterised by its small body size of 2.2-3.6 mm, hemispherical lip region, demarcated from body by a depression, funnel-shaped amphidial fovea and dorsally convex-conoid tail with a broadly rounded terminus. Paralongidorus dakarensis sp. n. closely resembles P. microlaimus and P. oryzae but differs from the former by shorter stylet (113-126 vs 125-136 μm), smaller c ratio (60-85 vs 85-150) and longer tail (35-49 vs 24-32 μm), and from the latter by longer stylet (113-126 vs 92 μm) and longer tail (35-49 vs 30 μm). Paralongidorus bullatus females from seven localities were measured and compared with the type population from Niger. Senegalese specimens were in general less slender and in some cases shorter or longer than those of the type population. Specimens originating from Tambacounda had a dorsally convex-conoid tail lacking the ventral curvature as described for the type population.
