Description
Summary:Meloidogyne sasseri n. sp. is described and illustrated from American beachgrass (Ammophila breviligulata) originally collected from Henlopen State Park and Fenwick Island near the Maryland state line in Delaware, United States. Its relationship to M. graminis, M. spartinae, and M. californiensis is discussed. Primary distinctive characters of the female perineal pattern were a high to rounded arch with shoulders, widely spaced lateral lines interrupting transverse striations, a sunken vulva and anus, and coarse broken striae around the anal area. Second-stage juvenile body length was 554 micrometers (470-650), stylet length 14 micrometers (13-14.5), tail length 93 micrometers (83-115), tapering to a finely rounded terminus. Male stylet length 20 micrometers (19-21.5), spicule length 33 micrometers (30-36). Scanning electron microscope observations provided additional details of perineal patterns and face views of the female, male, and J2 head. Wheat, rice, oat, Ammophila sp., Panicum sp., bermudagrass, zoysiagrass and St. Augustinegrass were tested as hosts. Distribution of the species was the coasts of Delaware and Maryland. The common name "beachgrass root-knot" is proposed for M. sasseri n. sp
