The most common species were P. penetrans, often associated with date palm (Phoeinix dactylifera L.), and P, thornei found in the rhizosphere of various cereal and vegetable crops. P. pratensis, P. scribneri and P. neglectus were occasionally found but always in low numbers. Brief descriptions and illustrations of the species are provided.
