Cosmorrhyncha landryi Brown and Razowski

sp. n.

Cosmorrhyncha landryi Brown and Razowski   , sp. n.

Fig. 8 View Figures 6–13 , 16 View Figures 14–21

Diagnosis. Superficially, C. landryi   is similar to the widespread C. ocelliferana   and C. parintina   from Brazil. The male genitalia are distinguished from those of congeners by the presence of two long, strong spines from the ventro-basal margin of the cucullus and a narrower, more distally attenuate valva, with the apex of the cucullus more elongate and tapered than in C. ocelliferana   and C. parintina   .

Description. Head. Reddish brown; labial palpus reddish brown, dorsum of second segment with bluishblack, narrow, longitudinal stripe; third segment mostly bluish black, slightly metallic. Thorax. Nota rust brown. Forewing ( Fig. 8 View Figures 6–13 ) length 6.5 mm (n = 1), pale rust-brown with faint refractive pale blue strigulae and dots, a small rounded, upraised patch of silver-white scales near distal end of discal cell, surrounded by small dark-brown circular patch; costa strongly bent downward at approximately 0.6 length from base to apex; distal 0.2 of costa faint orange with few black strigulae; median part of the costa weakly tinged with orange; costa without well-defined areas of dense silver-white striae. Fringe pale-orange tinged with brown. Hindwing brown; male with long, well defined anal roll. Fringe brown, paler in the anal area. Abdomen. Male genitalia ( Fig. 16 View Figures 14–21 ) with uncus short, stout, apically bifid, with dense cluster of long spines on each bifurcation; tegumen with rounded dorsal half; socius digitate, slightly broader basally, pendant, finely hairy; valva mostly parallel-sided in basal 0.5, upturned, attenuate, densely spined in distal 0.5; cucullus with a few strong setae along ventral edge in basal 0.5, one basal and one subbasal setae conspicuously larger; patch of long, slender, hairlike setae at venter immediately basad of cucullus; a distinct triangular subbasal process of valva bearing a single spine; juxta shield-shaped; phallus short, stout, vesica with one slender cornutus. Female unknown.
