Notes

Two new genera and species from Kenyan tidal areas, Polkepsilonema mombasae gen. et sp. n. and Pternepsiolonema servaesae gen. et sp. n., are described. Both are characterized by the presence of at least fourteen subsephalic setae and by thick thorns on the ventral body region of males. In the first genus, eight to ten subcephalic setae are situated anterior to the amphid, and the ambulatory setae are bisinuous. In the second, the subcephalic setae are situated at the posterior edge of the rostrum, and the ambulatory setae are straight. A key to the 13 genera of the Episilonematidae is presented.
