Diagnosis.

Ethmia helenmillerae  is distinguished by its smaller size and white forewings with spaced black markings, dark brown HW, valva in male genitalia with 2 long spines inwardly directed, and female genitalia lacking a signum.

Description.

Male: FW length 6.3-6.8 mm (n = 3). Head: Labial palpus elongated exceeding base of antenna, whitish; proboscis, front and crown white. Thorax: Tegula and collar white, pronotum white with four dark brown spots, one pair under tegula apices, the other at scutellum. FW ground color white, 6 defined dots distributed on 2/3 from base: three at costal area approaching costa and three at posterior half, triangulated; terminal area with a line from almost center of the wing to tornum, a wider and curved line from costa just before apex to middle of wing; terminal line black, fringe whitish. HW ground color dark brown, costal fringe pale ochreous. Abdomen: Dark brown, genital scaling pale. Genitalia (Fig. 71) with uncus and gnathos absent, apex of valva produced into a lobe with a “plume” with dense setation, base of plume with shorter setae transversely directed to setae at plume; a group of seven long spines bellow apex, two inwardly directed; a short pointed sacculus projection below spines.

Female: FW length 6.5-7.5 mm (n = 2). Head and thorax: As described for male. Abdomen: Genitalia (Fig. 116) with sterigma a simple band lightly sclerotized; antrum laterally enlarged; corpus bursae a simple sac with no signum.

Distribution and biology.

Ethmia helenmillerae  has been collected in ACG dry forest on the Pacific slope of Cordillera Volcánica de Guanacaste from 0 to 579 m. The food plant and immature stages are unknown

Etymology.

Ethmia helenmillerae  is named in honor of Helen Miller of Arlington, Virginia, an early major donor for ACG rain forest purchase, and her production of Scott Miller, Smithsonian Institution, Washington, DC, a faithful supporter of ACG inventory for biodiversity development.
