Loneura duckei n. sp. Male

( Figs 26–31 )

Diagnsosis. It is related to L. erwini New & Thornton by wings, hypandrium and phallosome characters, differing from it in having the posterior processes of the central sclerite of the hypandrium much longer, curved outward only distally, and not in all its length as in L. erwini ; both posterior process of the anterior and posterior pair of endophallic sclerites much longer, besides, presence of an inconspicuous mesal endophallic sclerite, distinctly absent in L. erwini and L. carijona González Obando, Carrejo, Panche & García Aldrete , with which it is also related.

Color. Compound eyes black, ocelli hyaline; head pattern ( Fig. 26 ). Scape brown, pedicel pale brown, f1–f3 pale yellow. Mx4 light brown. Femora pale yellow with a distal, middle, and proximal hyaline band; tibiae pale brown with distal ends brown; tarsomeres 1–3 pale brown. Right forewing ( Fig. 27 ), hyaline, with dark brown pigmented veins on M+Rs, R+Rs, pterostigma with broad brown bands proximally and distally, brown submarginal band from R 4+5 to areola postica as a set of downturned arches, a dark brown band from the middle of CuA to distal end of 1A; dark brown spots on vein ends at wing margin from R 4+5 to Cu1a. Right hindwing ( Fig. 28 ) with brown spots on vein ends at wing margin and between the final portion of Cu and margin.

Morphology. Right forewing ( Fig. 27 ); pterostigma elongate, narrow proximally, wider in the middle; areola postica tall, with round apex, insertion of Cu1a at the wing margin before the position of the first bifurcation of M; Rs shorter than its branches, convex basally, R 2+3 almost straight with a distal concave curve, R 4+5 sinuous, with a tenuous median convex curve; M stem distinctly concave proximally, then almost straight, with five primary branches, M 5 forked, resulting in M 5a and M 5b; right hindwing ( Fig. 28 ): Rs almost straight, R 2+3 straight, R 4+5 straight, downward directed; M with three primary branches. Hypandrium ( Fig. 29 ) anteriorly convex in the middle, deeply cleft in the middle, posterior projections elongate, distally slender, with acuminate outcurved ends, each with a subapical macroseta on inner margin; lateral anterior processes stout, slender proximally and widening distally; lateral posterior processes broad proximally and almost triangular distally; setae as illustrated. Phallosome ( Fig. 30 ) with side struts basally not fused, Y-shaped anteriorly, proximally narrow and widening distally, fused posteriorly to external parameres, ending in a lobed broad projection bearing a field of pores. Three pairs of endophallic sclerites; anterior pair broad based, with an inward projection and pointed ends, widening distally with an almost rectangular limit laterally and anteriorly, with middle projection bifurcated touching each other, and a wide posterior projection distally acuminate; antero-lateral pair weakly sclerotized, wide basally, curved inward, with acuminated ends; posterior pair wide proximally, elongate, longer than external parameres, slender distally, ending in rounded tips. Epiproct ( Fig. 31 ) trapezoidal, with two lateral large setae as illustrated. Paraprocts ( Fig. 31 ) broad based, triangular, acuminate, sensory fields with 22 trichobothria on basal rosettes, setae as illustrated.

Material studied. Holotype male. BRAZIL. Amazonas. Manaus, Reserva Florestal Adolpho Ducke , Igarapé Uberê. IX.2003. Malaise trap. João & Jailson Vidal.

Etymology. This species is dedicated to the naturalist Adolpho Ducke in recognition of his many and important pioneering research in the Amazonian forest. “Reserva Florestal Adolpho Ducke”, belonging to INPA, also honors him. The type of this species was found in this reserve.
