Synonyms and other taxonomic changes
Described by
Van Duzee in 1892
considered by
Metcalf in 1967 to be synonymous with
Deltocephalus flavicosta, but recognized by more recent authors as a distinct species
separated from
Deltocephalus into a new genus (
Planicephalus) by J.P. Kramer in 1971 (see bottom of
this page) but the erection of a new genus is considered unjustified in a comment
here by Andy Hamilton, who treats
Planicephalus as a subgenus of
DeltocephalusExplanation of Names
Latin flavus = "pale yellow" + costata = "ribbed" (in the specialized sense of the leading edge of the wing, which is referred to by entomologists as the costa). This is no doubt a reference to the yellow strip on the costa.
Identification
Adult: dark brown to blackish with yellow strip along anterior two-thirds of costa, terminating in a short white oblique dash; another short white dash nearer to wingtip, projecting at right-angles in from costa; several whitish dots on front of head; legs pale brown; eyes large, dark brown
Range
United States and southern Canada
the related Deltocephalus flavicosta, described by Stål in 1862, occurs from southern United States south to Argentina
