Helcystogramma octophora is a moth in the family Gelechiidae. It was described by Edward Meyrick in 1918. It is found in South Africa.[1]
The wingspan is 11–12 mm. The forewings are shining leaden grey with an irregular outwards-oblique orange fascia from the base of the dorsum, not reaching the costa. There is a deep bronzy blackish-edged transverse blotch from the dorsum somewhat before the middle, broadest on the dorsum, reaching three-fourths of the way across the wing, the apex rounded and margined by a crescentic orange streak. There is also an 8-shaped orange patch filled up with fuscous, entirely crossing the wing beyond the middle from the costa to the dorsum, edged with blackish. There is also a rather curved orange line from four-fifths of the costa to just before the tornus, strongly indented in the middle, edged anteriorly with irregular black scales and posteriorly with blackish suffusion. There is also a black basal line, which is light grey beneath tornus. The hindwings are grey.[2]
