= Dicranotropis (?) luteivitta (Walker, 1851); comb. by Van Duzee 1916: 84.
= Stenocranus luteivitta (Walker, 1851); comb. by Muir and Giffard 1924: 12; to incertae
sedis
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).
