Figures 6, 7
= Delphax luteivitta Walker, 1851: 354.
= Dicranotropis (?) luteivitta (Walker, 1851); comb. by Van Duzee 1916: 84.
= Stenocranus luteivitta (Walker, 1851); comb. by Muir and Giffard 1924: 12; to incertae
by Beamer (1946: 1).
= Delphacodes luteivitta (Walker, 1851); comb. by Bartlett 2010: 472.

Note – As described in Bartlett & Webb (2014), the type specimen of ‘Delphax luteivitta‘ is in poor condition and it could not be determined whether the species was the same as either of the described species (and therefore is the senior name to either of the other species), or represents a different biological entity.

Economic Importance: Limited.

Plant associations:

Spartidelphax detectusSpartina patens (Aiton) Muhl. (Poaceae, saltmeadow cordgrass), Spartina alterniflora Loisel. (smooth cordgrass) (Denno 1977, 1978), with S. alterniflora “…an inferior host plant for development” (Denno 1977: 366). Distichlis spicata (L.) Greene (saltgrass, Poaceae) was reported on specimen labels. (S. detectus is probably Spartina patens specialist with the other reported host associations accidental)

Spartidelphax penedetectusSpartina alterniflora Loisel. (smooth cordgrass) (Wilson et al. 1994, Ferrenberg & Denno 2003).

Plant names from USDA PLANTS; plant associations from Denno 1977, Wilson 2012, Bartlett & Webb 2014.

Molecular resources:

BOLD does not explicitly list Spartidelphax at this time (19 Sept. 2017); however, data is available for Delphacodes detecta and D. penedetecta; at least as identified; Genbank also has some data for D. detecta and D. penedetecta.
