Exoteleia graphicella

(Busck, 1908)

Exoteleia graphicella is a small gelechiid described by Busck in 1908. It is characterized by distinctive wing patterning with bold brown transverse bands on a white forewing background. The is known only from California, with records based on limited observations.

Identification

Distinguished from similar Exoteleia by the specific arrangement of black raised tufts within the outer brown fascia—four tufts arranged in two pairs. The nearly straight-edged, perpendicular orientation of both brown fasciae to the wing margin, combined with the black costal base and the relative width difference between the two fasciae (outer nearly twice as broad as inner), provides diagnostic characters. The overall white ground color with contrasting brown bands separates it from more uniformly colored gelechiids.

Appearance

Small with wingspan approximately 13 mm. Forewings white with two broad transverse brown fasciae: one near the wing base, the other at mid-wing and nearly twice as broad. Both fasciae are nearly straight-edged and perpendicular to the wing edge, with the outer fascia slightly concave exteriorly. Black raised present in both fasciae; in the outer fascia these form four small tufts (one pair at the basal edge, one pair near the edge). Extreme base of black. Wing tip suffused with light brown and fuscous scales. Hindwings whitish fuscous.

Distribution

Recorded from California, United States. Distribution appears restricted to this region based on available records.
