A.S. Eroshenko and T.V. Volkova (1997)
Two new species of Criconemella (Tylenchida: Criconematidae) from meadows in the Primorsky region, Russian Far East
Russian Journal of Nematology 5 (1), 27-30
Abstract: Two new species Criconemella ripariensis sp. n. and C. sigillaria sp. n. are described from specimens collected from the rhizosphere of Carex appendiculata and C. lasiocarpa growing in meadows in the Khassan district of the Primorsky region, Russia. Criconemella ripariensis sp. n. is characterized by the presence of 125-150 cuticular annules, stylet 64-73 µm long, conical tail curved on the dorsal side and deformed annules on the tail terminus. C. sigillaria sp. n. is characterized by the presence of 115-127 cuticular annules with anastomoses, stylet 46-51 µm long and conical tail with dorsally curved terminus with numerous finger-like appendages. Macroposthonia digiticauda Eroshenko and Volkova, 1988 is transferred to Criconemella digiticauda (Eroshenko and Volkova, 1988) comb. n.
