Ethmia laphamorum Phillips  sp. n. Figures 29, 74, 119, 161


Ethmia laphamorum  can be distinguished from Ethmia nigritaenia  , its most similar species, by the smaller size and the less contrasting line through the middle of the FW from base to apex. In the male genitalia Ethmia laphamorum  presents a very reduced “plume” projection at the apex of the valva and the distal spines are absent. In the female genitalia, the sclerotized sleeve at the base of ductus is shorter than that of Ethmia nigritaenia  .


Male: FW length 10.8-12 mm (n = 3). Head: Labial palpus curved, long, exceeding base of antenna; proboscis and front white with lateral brownish markings, crown light brown, occipital tuft dark brown at mid-dorsum. Thorax: Pronotum light brown with black spots marginal. FW brownish with irregular darker markings; posterior area with an elongated dark mark at 0.3 × from base; an irregular black band from base to apex. HW whitish; costal fold to 0.7 × from base, enclosing a whitish brush of elongate hair scales from base. Abdomen: Pale ochreous dorsal and ventral, bright ochreous tergum I and II, genitalia scaling concolorous. Genitalia (Fig. 74) with uncus sclerotized; valva apex with a very reduced “plume”, distal spines absent; a large finger like projection at sacculus, below apex.

Female: FW length 11.1-12.7 mm (n = 3). Head and thorax: As described for male, except HW unmodified. Abdomen: Genitalia (Fig. 119) with sclerotized sleeve at base of ductus bursae; signum with posterior margin serrated.

Distribution and biology.

In Costa Rica (Fig. 161), Ethmia laphamorum  has been collected on both slopes of Cordillera Volcánica de Guanacaste and Península de Nicoya, from 20 to 600 mts. It occurs in ACG dry forest.

The food plant and immature stages are unknown.


Ethmia laphamorum  is named in honor of Nick and Gardiner Lapham of Rappahannock, Virginia for their many years of support of ACG rain forest land purchase for permanent wildland conservation.
