The nematode communities of 36 grassland ecosystems in Romania, belonging to different plant associations and soil types, were studied. The abundance of nematodes, the species and trophic types present, as well as their distribution in relation to plant community and soil characteristics are analyzed and discussed. The abundance of nematodes from the 36 grasslands studied ranged between 0.41 × ...

Pratylenchus quasitereoides n. sp. is described from Western Australia. It is characterized by 2 external incisures in the head cuticle, 4 lateral incisures at mid body, stylet length 17 µm to 19 µm, V greater than 75%, PUS less than 2 body diameters long and crenate tail terminus. Molecular data confirm the separation of the new species from morphologically similar and sympatric congeners. The...

Mylocliscus nanus Thorne, 1939 is redescribed from specimens collected in the State of Bahia, Brazil. It has an axial odontostyle and therefore does not belong with Aetholaimus Williams, 1962 to the Nygolaimidae, subfamily Aetholaiminae. The abrupt esophageal expansion, location of dorsal esophageal gland orifice, and presence of oval organs in the lateral chord indicate that it belongs to Disc...
