Explanation of Names
Syndelphax Fennah, 1963
7 spp. n. of Mex. Additional species belonging to this genus are currently misplaced in the polyphyletic genus Delphacodes. This genus is being revised and the transfer of these species is expected in the near future. (2)
~2 mm (BG data)
Syndelphax spp. usually yellow to straw-colored. Brachypters very common and males often have contrasting dark tegmina (rarely females also). Females not identifiable to species except by association with a male. Macropters common and often found at lights. (2)

Life Cycle
Syndelphax [=Liburnia] pseudoseminigra recently found to be a pest of St. Augustine grass in Florida (3)
Syndelphax sp. found to be a lawn pest in n. TX in Sept. 2015. (Mike Merchant, pers. comm. to MAQ, 2015)

Females are strikingly similar to Toya, Metadelphax, Harmalia, and some Delphacodes and generic placement of females in the absence of males can be doubtful. (2)
