Descriptions of two new record species of Scutellonema (Nematoda：Tylenchida) from China

From 2011 to 2012, we collected Scutellonema commune from the rhizosphere soil of coconut (cocos nucifera L.) and Scutellonema magniphasma from the rhizosphere soil of Rosa chinensis in Shenyang, China. S. commune was characterized by rounded scutella, which was varied from two annules anterior to the anus and five annules posterior. The lateral field was not areolated at the level of scutella. S. magniphasma was characterized by varying scutellum, about 7.0um in diameter, in position from four annules posterior to four annules anterior to the anus, and areolated at the level of the scutellum.
