Described from the female holotype (10 Mar 1959, J. F. G. Clarke) and three female paratypes with identical data, except one, 12 Mar 1959.

Aside from certain species of Chionodes (Gelechiidae) I know of no species with which D. lineola can be favorably compared, unless one refers to Borkhausenia praesul Meyrick from Argentina. In the case of B. praesul, it is a larger moth and the dark markings of D. lineola are more extensive than those of B. praesul. Moreover, B. praesul lacks the white transverse line at apical fourth of forewing, present in D. lineola.

Macarocosma Meyrick

Macarocosma Meyrick, 1931:393. [Type-species: Macarocosma philochrysa Meyrick, 1931; by monotypy.]

Deia lineola is a moth in the family Oecophoridae, the only species in the genus Deia. It was described by John Frederick Gates Clarke in 1978. It is found in Chile.

The wingspan is 11–12 mm. The forewings are blackish fuscous, from the middle of the costa to the dorsum a broad white fascia with scattered blackish-fuscous scales and from the apical fourth of the costa to the tornus a straight, white, transverse line. Beyond this line, a patch of olivaceous-grey scales is found and the termen is narrowly white. The hindwings are light grey, somewhat darker toward the margins.
