Numbers
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)
Size
~2 mm (BG data)
Identification
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)

Per Bartlett (2)
Syndelphax alexanderi (Metcalf) - e US (MS-FL-NJ-KS)
Syndelphax fallax (Muir) - TX / S. Amer.

Syndelphax fulvidorsum (Metcalf) - se US (TX-FL-NC-MO) / Mex. to Panama / W. Indies
Syndelphax humilis (Van Duzee) - FL / Mex. to S. Amer. / W. Indies
Syndelphax nigripennis (Crawford) - TX / C. Amer. / W. Indies
Syndelphax pseudoseminiger (Muir and Giffard) - FL-GA
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)
See Also
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)
