Other material examined and distribution. Mexico: States of Chihuahua, Durango (Sierra Madre Occidental), Mexican Federal District. USA: Arizona: Cochise Co. (Huachuca Mts) and Santa Cruz Co. (Santa Rita Mts).

Diagnosis. Superficially Bryolymnia viridimedia can be recognized by large size (forewing length: 14–18 mm), extensive pale-green shading in the medial area, and the course of the antemedial line on the forewing. On the forewing the antemedial line has a rectangular indentation between the cubital and anal veins, and an outward loop below the anal vein; the basal area is black, except for the area below the anal vein, which is pale green; the subterminal and terminal areas are mainly brown with gray scales (mainly adjacent to the lower part of the postmedial line, and with a dark-fuscous truncated wedge-shaped patch on the costa. Th e hindwing is pale fuscous with darker shading on the veins, discal spot, postmedial line, and wing margin. Bryolymnia viridimedia is similar to B. poasia Schaus, 1911 from Costa Rica (Figs. 4, 5, 26, 35) and B. marti (described below). Bryolymnia poasia is smaller (forewing length: 12–14 mm) than B. viridimedia , the forewing medial area is white or whitish buff, not green, and the genitalia differ. Male genitalia. In B. viridimedia the cucullus is short, similar in width to the rest of the valve, and has a partial corona on the dorsal-apical margin; the clasper is a simple finger-like process with a large rounded or slightly lobed sclerotized plate on the dorsal-anterior rod at the base of the clasper. The vesica has two dense patches of long spines ventrolaterally on the right, one postmedial and one preapical, the latter on a short diverticulum. In B. poasia (Fig. 26) the valve is straighter and narrower toward the base, the rounded sclerotized plate on the dorsal-anterior rod at the base of the clasper is larger and more rounded, and the vesica is short with a single large basal cornutus on a large base. Female genitalia. The corpus bursae is oval, 4 × as long as abdominal segment eight and 0.8 × as long as the ductus bursae. Th e ductus bursae is long and narrow with irregular sclerotized ridges longitudinally, especially mesially and anteriorly. Th e ostium bursae has an elongated heavily sclerotized plate in the ventral wall with rounded sides and a deep central notch posteriorly.

Distribution and biology. Bryolymnia viridimedia occurs from southeastern Arizona (Huachuca and Santa Rita Mountains) southward in the Sierra Madre Occidental to the Mexico City area. Collecting dates range from early July to mid-September. Bryolymnia bicon occurs south of the range of B. viridimedia , from the State of Veracruz in central-eastern Mexico southward to Costa Rica.
