Loneura marinonii n. sp.

(Figs 13–25)

Diagnosis. It differs from the other species of Loneura in Group I by having the central sclerite of the hypandrium with three posterior projections, one short median projection and two slightly longer lateral projections, the three with rounded apices. Forewing pigmentation pattern similar to L. colombiana García Aldrete, González Obando & Carrejo.

Male. Color. Compound eyes black, ocelli hyaline; head pattern (Fig. 13). Scape brown, pedicel pale brown, f1–f3 pale brown. Mx4 light brown. Femora pale yellow; tibiae pale yellow; tarsomeres 1–3 pale yellow. Right forewing (Fig. 14) with dark brown pigmented veins on M+Rs, R+Rs, pterostigma with brown spots proximally and distally, dark brown spots on vein ends at wing margin from R 2+3 to Cu1a, a brown spot at confluence of CuA and wing margin, CuP–1 A. Right hindwing hyaline, veins brown (Fig. 15).

Morphology. Outer cusp of lacinial tips broad, with six short denticles (Fig. 16). Right forewing (Fig. 14), pterostigma narrow proximally, wider in the middle; areola postica wide, tall, semicircular; Rs longer than its branches, convex basally, R 2+3 sinuous, with a median convex curve, R 4+5 sinuous with a median convex curve; M stem slightly concave proximally, then almost straight, with six primary branches, M6 trifurcated, resulting in M 6a, M 6b and M 6c; Right hindwing (Fig. 15) R 2+3 straight, R 4+5 curved medially; M with four branches. Hypandrium (Fig. 17). Phallosome (Fig. 18) with side struts basally fused, anteriorly V-shaped, wide, narrowing distally, ending in rounded, straight projections, not fused to external parameres, these stout, posteriorly ending in a broad lobed projection bearing a field of pores. Three pairs of endophallic sclerites; an anterior pair U-shaped, with wide and inward curved projections, ending in outward directed, slender tips; mesal pair wide, not fused at base, with wide and inward curved projections with a lateral protuberance, narrowing distally, ending in outwardly directed, slender tips; posterior pair scythe-shaped, elongate, tapered, with rounded proximal ends, a median constriction, slender distally, ending in an elongate outward curved tip. Epiproct (Fig. 19) triangular, with three central large setae as illustrated. Paraprocts (Fig. 19) broad based, with straight distal margin, sensory fields with 33 trichobothria on basal rosettes, setae as illustrated.

Female. Color. Compound eyes black, ocelli hyaline; head pattern (Fig. 20). Scape brown, pedicel pale brown, f1–f3 pale brown. Mx4 light brown. Femora pale yellow; tibiae pale yellow; tarsomeres 1–3 pale yellow. Right forewing (Fig. 21) with dark brown pigmented veins on M+Rs, R+Rs, pterostigma with brown bands proximally and distally, brown spots on vein ends at wing margin from R 2+3 to Cu1a, a brown spot at confluence of CuA and wing margin, CuP–1 A. Right hindwing hyaline, veins brown (Fig. 22).

Morphology. Right forewing (Fig. 21); pterostigma elongate, narrow proximally, wider in the middle; areola postica wide, with round apex; Rs straight, R2+3 almost straight, with a convex curve medially, R4+5 with a convex curve distally; M stem slightly concave proximally, then almost straight, with six primary branches, M6 forked, resulting in M6a and M6b. Right hindwing (Fig. 22): Rs almost straight, R 2+3 straight, R 4+5 slightly curved medially; M with three primary branches. Subgenital plate (Fig. 23) broad based, with sides converging to a pointed apex, pigmented area wide, V-shaped posteriorly, setae as illustrated. Ninth sternum (Fig. 24) broad, anteriorly almost square, with a strongly pigmented area concave. Gonapophyses: (Fig. 24) v1 long, wider proximally and narrowing distally, with acuminate apex; v2+3 stout, with rounded proximal heel, distal process stout, short, distally pointed. Epiproct (Fig. 25) triangular, setae as illustrated. Paraprocts (Fig. 25) triangular, with rounded apex, sensory fields with 21 trichobothria on basal rosettes, setae as illustrated.

Material studied. Holotype male. BRAZIL. Paraná. Guarapuava. Est. Agua Sta. Clara. 22.IX.1986. Malaise trap. Profaupar, P –1 (without remaining parts); 1 paratype female (INPA). Same country, state, and city as the holotype. 06.IV.1987. Malaise trap. Profaupar, P –3 (without remaining parts).

Etymology. This species is dedicated to Dr. Renato Marinoni (1939-2011), who oversaw the Profaupar project, for his great contribution to the knowledge of the fauna of the state of Paraná, including the collection of the specimens of the species here described to honor him.
