Bucculatrix ericameriae Braun 1963

Bucculatrix ericameriae new species (Figs. 93, 93a, 93b.)
Face and tuft white, eye-caps white, a few basal segments of antennal stalk entirely white, remainder of stalk conspicuously blackish-annulate. Fore wings white, with markings formed by brown-tipped ocherous scales ; a line of such scales along costa from base diverges from costa just before middle forming a short slender oblique streak not attaining the middle of the wing; from twothirds of costa, a broader oblique streak crosses the wing to tornus, the scales of its outer margin more broadly blackish-tipped ; before apex, an irregular costal spot, its inner margin touching the outer margin of the oblique streak in the middle of the wing; on middle of dorsum, a large irregular spot, inwardly margined by a row of blackish scales, and bearing on fold a few raised scales; a short line of blackish-tipped scales opposite apex in the cilia, and a second line of such scales through the white cilia from apex to tornus. Hind wings and cilia fuscous. Legs whitish, tarsal segments conspicuously dark-tipped. Abdomen shaded with fuscous above, whitish beneath.
Alar expanse 8 mm.
Female genitalia (figs. 93, 93a, 93b). Ovipositor lobes setose, with minute setae amongst the larger setae ; near posterior margin of segment 8, a pair of membranous lobes, clothed with remarkable flattened specialized setae lying nearly in a dorso-ventral plane ; each seta consists of a thin plate broad at the tip, the margin of one side thickened (fig. 93a) so that when viewed from the ventral side they appear as slender curved hairs (fig. 93) ; ostium small, round, opening into a broad elongate sinus, with widely flaring margins ; groups of specialized scales on posterior margin of segment 7 (position indicated on the figure by scale sockets) ; signum ribs with long slender spines, and an occasional heavier spine (fig. 93b).
Type. — 2, Placerville, California, 5-1-16, on Ericameria arborcscens (Gray) Greene, F. B. Herbert. Coll. [U.S.N.M., Type No. 65019]. Paratype. — $, same data as the type.
Only the female is known.
Although this species displays a general type of markings common to many western species of the genus, the unusual female genitalia will serve to separate it from all other species of our fauna.

Bucculatrix ericameriae is a moth in the family Bucculatricidae. It is found in North America, where it has been recorded from California. It was first described by Annette Frances Braun in 1963. Adults have been recorded on wing in March.

The larvae feed on Ericameria arborescens.
