Loneura manauara n. sp. Male

(Figs 7–12)

Diagnosis. It differs from the other species of Loneura in Group I by having the central sclerite of the hypandrium with a median posterior projection distinctly forked distally, with two short lateral acuminate projections, and a slender, long connection joining the central and the lateral sclerites. Phallosome with a distinct mesal sclerite, external parameres distally with a spiral sclerotized area. Forewing pigmentation pattern similar to L. maesi García Aldrete.

Color. Compound eyes black, ocelli hyaline; head pattern (Fig. 7). Scape brown, pedicel pale brown, f1–f3 pale yellow. Mx4 light brown. Femora pale yellow; tibiae pale yellow; tarsomeres 1–3 pale yellow. Right forewing (Fig. 8), right hindwing (Fig. 9), hyaline.

Morphology. Right forewing (Fig. 8) with elongate pterostigma, narrow proximally, wider in the middle; areola postica wide, tall, apically rounded; Rs longer 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 concave proximally, then almost straight, with six primary branches; left forewing same as the right, except M with six primary branches, M6 bifurcated, resulting in M 6a and M 6b; hindwings (Fig. 9) Rs almost straight, R 2+3 straight; M with three primary branches. Hypandrium (Fig. 10) of three sclerites, a central one flanked anteriorly by stout, irregular side sclerites, semicircular, anteriorly convex, with one median posterior projection distinctly bifurcated distally, with two short, lateral acuminate ends, and a postero-lateral, tapered, long connection linking the central and lateral sclerites; setae as illustrated. Phallosome (Fig. 11) with side struts basally not fused, Y-shaped anteriorly, proximally narrow and widening distally, not fused posteriorly to external parameres, these stout, proximally with inward turned projections, touching each other, anteriorly almost square, bearing a field of pores in central area, with an anterior spiral sclerotized area and short teeth along outer margin distally. Mesal sclerite convex anteriorly and concave posteriorly, anteriorly with a pair of median projections, outward directed, with rounded ends, sides of sclerite extended, acuminate. Two pairs of endophallic sclerites; anterior pair U-shaped, tapered, wide, slightly narrow in the middle, with rounded proximal and distal ends; a posterior pair scythe-shaped, proximally elongate, with rounded ends, medially sclerotized and wide, distally with a scythe-shaped bifurcation. Epiproct (Fig. 12) semicircular, setae as illustrated. Paraproct (Fig. 12) triangular, with straight distal margin, sensory fields with 27 trichobothria on basal rosettes, setae as illustrated.
