Diagnosis: Grumichella flaveola   can be diagnosed by the following characters: male forewings with 9 brown spots; male genitalia with 1st article of inferior appendage with small basomesal protuberance; 2nd article 1/2 to 1/3 of length of apicodorsal portion of 1st article; apex of 2nd article acuminate, curved mesal; larval abdominal sternum I with 2 pairs of short setae. It is most similar to G. pulchella   , except for the quadrate apicodorsal portion of 1st article of the inferior appendage.

Adult: Head and body yellowish.

Male: Forewing length: 11–12 mm (N = 5). Forewing light golden brown, with 9 small brown spots ( Fig. 3). Abdominal segment IX annular; in dorsal view, with anterior margin nearly straight, posterior margin broadly rounded; in lateral view, pleural region setose; tergum IX without protuberances dorsally. Preanal appendage setose, at least 4× as long as wide; in lateral view, clavate, apex rounded. Segment X saddle-shaped; in lateral view not flattened, dorsal margin abruptly concave at 2/3 length, with apex upcurved, ventral margin slightly convex; segment X in dorsal view, subtriangular, with posterolateral borders not developed, lateral margins sinuate, narrowing apically, with apicodorsal shelf, shelf almost rectangular, 1/3 as wide as apex of segment X, without sulcus apically. Inferi- or appendage nearly straight in ventral view, with basal region tuboid, not enlarged; slightly rounded basally, setose, bearing a small basomesal protuberance; middle region of inferior appendage without constriction before apicodorsal region; 2nd article shorter than apicodorsal portion of 1st article, broad basally, tapering throughout length, mesal surface not excavate, apex pointed, curved mesally; apicordorsal portion of 1st article digitate, setose. Phallic apparatus simple, phallicata sharply down-curved; with pair of subequal, wide, posterodorsally directed lateral flanges, apices not acuminate; phallotremal sclerites small, U-shaped in dorsal view.

Female: Head and body yellowish. Forewing length: 7–8 mm. Forewing yellowish to brown, without dark setae on posterodorsal region. Genitalia inseparable from congeners ( Fig. 4). Abdominal segment IX lightly sclerotized, with dorsal plate, bearing pair of setose protuberances above appendages of segment X, appendages of segment X small; valves flat, thin, lightly sclerotized, with very short setae.

Larva: Head light brown, thoracic sclerites light brown, legs yellowish to brownish, with dorsal borders of middle and hind femora black. Length of larva 8 mm. Abdominal sternum I with 2 pairs of short, thin setae; lateral hump sclerite very small.

Larval case: Length   9 mm; constructed of alternating rings of clear and dark brown silk, nearly straight, tapered, wide, with 2 distinct diagonal sutures, 1 towards posterior end and 1 more or less at midlength, posterior end with ventral, dorsally directed projection, visible externally, posterior aperture C-shaped.

Pupa: Segment IX slender; anal process short, roughly trapezoidal in general shape, tapering posteriorly to narrow apex, with basodorsal, pigmented area shaped like a parallelogram, apically upturned, hooked.

Pupal case: With   anteroventral silken pedicel, pedicel short; anterior silken membrane with 3 small openings arranged in a triangle.

Distribution: Argentina, Bolivia, Colombia, Ecuador, Peru, and Venezuela.
