Type material. Holotype male – “Republica Dominicana: / Pedemales; P.N. Sierra de Bahoruco / Caseta 2; 18°12.24' N 71°31.11' W / 12 v 2004 el. 1790 m A Luz Murcurio / coll. D. Lawrie and C. Nuñez ”; HOLOTYPE / Panthea reducta / Anweiler” [red label]; deposited in CNC [for eventual return to Dominican Republic] . Paratypes – (4 ♁): Dominican Republic, same data as holotype, except 1 ♁, 11.vi.2004 [ CNC – for eventual return to Dominican Republic] .

Etymology. The name refers to the greatly reduced size and density of scales on the hindwing.

Diagnosis. P. reducta can be recognized as a Panthea by the typical Panthea forewing pattern, and by structural characters including the reduced and apparently non- functional mouthparts and characteristic modified Panthea uncus. The glassy translucent hindwing is unique in Panthea . It is also the only Panthea known from the Caribbean. Females are unknown.

Description. Head – male antenna bipectinate, pectinations about 2 × as long as width of antennal shaft; head and collar clothed in long dense white, lightgray, and brown-black hair-like scales. Thorax – with long dense white and black hair-like scales, tegulae crossed midway and along edge by poorly defined dark bands. Dorsal forewing – length 16-18 mm, (n=4), ground a mixture of white, gray-brown and black scales; basal line indicated by a small patches of black scales; antemedial line black, erratic, angled distad at anal vein; medial line broad, incomplete and poorly defined, most prominent as patches of black scales below cubital vein and at and below costa; postmedial line black, slightly erratic, angled outward below vein Cu2, defined by white scales bordering distal side; subterminal line parallel to postmedial line, starting at anal angle, almost obsolete and defined by white scales outlining distal border; fringe gray with bright white outer edge, checkered with white at veins. Dorsal hindwing – translucent, clothed in tiny hair-like black scales, some finely forked at the tip under magnification, mixed with sparse long dark hair, densest along inner margin; white scales confined to small area along upper and lower margin; fringe black, with white tips in some specimens, checkered at veins with white; wing membrane exposed by reduced scales, glassy, translucent, allowing the lettering on label below to be clearly discerned through wing. Abdomen – clothed in short stiff lead-gray and white hair-like scales. Male genitalia – ( Fig. 47 ) valve simple, short and broad, approximately 2 × as long as wide; cucullus bluntly rounded; clasper well-developed, slightly flattened, rod-like with a blunt tip, about ½ as long as width of valve at midpoint; tegumen with pair of small subuncal lobes; uncus approximately 2 × as wide as high, resembling a duck’s beak; tapering gradually to a broad, blunt terminus; aedeagus short, thick, about 3 × as long as wide; inflated vesica bulbous, short, wide, shaped like a hammer head, armed with a single large sharp curved cornutus on dorsal side near base, oriented anteriorly; ductus seminalis exits near base of vesica on dorsal side.

Distribution and biology. P. reducta has been collected at 1800 m elevation in a Hispaniolan pine ( Pinus occidentalis Swartz ) forest in Sierra de Bahoruco National Park in the Dominican Republic ( Fig. 70 ). Hispaniolan pine is the presumed larval host.
