Bryolymnia marti

Description. Adults. Male and female similar in size, color, and maculation. Head – Male antenna with flagellomeres very slightly swollen laterally; setae tending to group into two or three clusters on each side of each segment. Palpi and head a mixture of broad, apically serrated pale-brown and blackish-brown scales predominating. Thorax – Covered with scales similar to those on head, except blackish-brown scales predominating; a slightly divided dorsal tuft on metathorax. Legs: Covered with blackish-brown scales with white band in middle of tibiae and at apices of tarsal segments. Tibia without spiniform setae. Wings: Fore­wing length: 11–12 mm. Dorsal fore­wing ground color black in basal and antemedial area, pale whitish green in medial area, and a mixture of black, brown and greenish gray in subterminal and terminal areas; subterminal line with concave notch between cubital and anal veins, and bending abruptly toward wing base below anal vein; medial line obscure or diffuse in most specimens; postmedial line black, slightly serrated with a series of short wedge-shaped extensions projecting into medial area; subterminal line evident only near costa where blackish gray in upper part of subterminal area contrasts with paler greenish gray in upper part of terminal area; terminal line black; fringe dark gray with white scales at end of veins; orbicular spot usually obscure but outlined partially or completely in black in some specimens; reniform spot shaped like figure 8 but upper part usually obscure, lower part white with black outline and small black central dot.
Dorsal hindwing white with varying amount of fuscous, especially on veins, discal spot, postmedial line, and wing margin; females averaging slightly darker than males; fringe fuscous with white basal line and sometimes with white on outer margin. Male genitalia – Uncus cylindrical, tapered to spine-like apex. Valve somewhat oval, broad mesially, tapered apically with dorsal margin angled upward at membranous part of costa; cucullus with weak corona on apical half of outer margin; digitus long and tubular, fused to costal margin of valve to costal angle, then free of valve and slightly spatulate; apical part of clasper slender and very slightly upcurved, dorsal part of basal rod extending to dorsal margin of valve enlarged into apically rounded process extending beyond dorsal margin of valve; apical part of sacculus beyond postmedial suture more heavily sclerotized than basal part. Aedeagus irregularly sclerotized with narrow sclerite extending onto vesica ventrally to base subbasal bend in vesica. Vesica about 1/2 as long as aedeagus with postmedial cornutus tapered to sharp point. Female genitalia – Corpus bursae membranous, oval, slightly shorter than ductus bursae, with single long signum ventrally and ductus seminalis arising on right near junction with ductus bursae. Ductus bursae long and slender, membranous except for lightly sclerotized band about 3/4 from posterior end. Ostium bursae with broad sclerotized plate in ventral wall with deeply concave posterior margin.

Distribution and biology. Bryolymnia marti occurs from central New Mexico and east-central Arizona southward to the State of Durango in northern Mexico. Adults have been collected between early June and early July in conifer forests.
