(Figs 1–21)
Diagnosis. Belonging in species group IB of García Aldrete et al. (2011), this species is related to L. boliviana and L. meridionalis by the hyaline wings and hypandrium arrangement but differs from it in having the phallosome with external parameres long and slender, in having the anterior pair of endophallic sclerites basally straight, besides having an anterior central projection with a group of spines along the outer margin.
Male. Color. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern (Fig. 1). Scape brown, pedicel pale brown, f1–f3 pale yellow. Femora pale with a brown belt at proximal ends; tibiae pale yellow with distal ends brown; tarsomeres 1 pale brown with distal ends brown, tarsomeres 2–3 brown. Forewings (Fig. 2) almost hyaline, veins brown, pterostigma with proximal and distal pale brown bands, a brown spot at R–Rs crossvein and at confluence of CuP–1A. Hindwings (Fig. 3) hyaline, veins brown, a brown spot at wing base.
Morphology. Compound eyes without interommatidial setae. Outer cusp of lacinial tips (Fig. 4) broad, with five denticles. Right forewing (Fig. 2) pterostigma elongate, narrow anteriorly, wider in the middle; areola postica tall, broadly triangular, apically round; Rs long, slightly concave proximally, R 2+3 almost straight, R 4+5 sinuous; M stem slightly concave proximally, then almost straight, with six primary branches, M 6 forked, resulting in M 6a and M 6b. Right hindwing (Fig. 3) M with four primary branches, M 4 forked, resulting in M 4a and M 4b (Figs 15–21; see also variations of the wings of female specimens). Hypandrium (Fig. 5) of three sclerites, central sclerite “U” shaped, convex anteriorly, with two lateral posterior projections, rounded distally, curved outward; irregular side sclerites narrow distally, setae as illustrated. Phallosome (Fig. 6) with side struts basally not fused, V-shaped, not fused posteriorly to external parameres, these long and slender, proximally slender and widening distally ending in a curved inward projection with a field of pores; two pairs of endophallic sclerites; an anterior pair U-shaped, anteriorly straight and serrated at the base, with two projections, a central inner shorter, very thin distally, posteriorly with a sclerotized area and a spine group along the outer margin, and a lateral external longer and curved outward, with a sclerotized area on both inner and external margins, posteriorly with a short and slightly acuminate projection, laterally with a radular posterior margin and a lobed end; two partially sclerotized membranes curved outward between the base of the anterior pair of endophallic sclerites; a posterior pair elongate, irregular, proximally concave with a very thin curved, apical end scythe-shaped and distally turned outward with short acuminated end projection. Epiproct (Fig. 7) trapezoidal, posteriorly slightly rounded, with two lateral large setae as illustrated. Right paraproct (Fig. 7) broad-based, triangular, sensory fields with 34 trichobothria on basal rosettes, setae as illustrated.

Female. Color. Essentially as in the male.
Morphology. Compound eyes (Fig. 8) without interommatidial setae. Outer cusp of lacinial tips (Fig. 11) broad, with five denticles. Right forewing (Fig. 9) pterostigma elongate, narrow basally, wider in the middle; areola postica tall, trapezoid, apically rounded; Rs long, slightly concave basally, R 2+3 almost straight, R 4+5 sinuous; M stem slightly concave proximally, then almost straight, with seven primary branches, M 7 forked, resulting in M 7a and M 7b; Right hindwing (Fig. 10) M with three primary branches (Figs 15–21; see also variations of the wing female specimens). Subgenital plate (Fig. 12) broad, straight basally, subtriangular, with sides converging to a pointed apex, with lateral pigmented areas, setae directed to the inner and anterior area as illustrated. Ninth sternum (Fig. 13) strongly sclerotized, subtrapezoidal, anteriorly with a deep central cleft, posteriorly straight at base, with two latero-posterior elliptic areas and other almost square strongly pigmented at its center. Gonapophyses (Fig. 13): v1 long, with outer margin heavily sclerotized, slightly wider in the middle and narrowing at the end, with acuminate apex; v 2+3 stout, with a large heel proximally, wide at the middle and narrowing at the end with three large setae on outer lobes and long acuminate apex. Epiproct (Fig. 14) wide-based, rounded and with setae anteriorly as illustrated. Right Paraproct (Fig. 14) subtrapezoidal, sensory fields with 27 trichobothria on basal rosettes, setae as illustrated.

Fore & hindwing venation variation. Five female specimens from Bolivia (4) and Peru (1) showed the following variations: (A) with no vein variation; female (B) left forewing M with seven primary branches with M 7 forked, resulting in M 7a and M 7b, from which an incomplete vein derives (Fig.15); female (C), left forewing M with seven primary branches with M 7 three branched, resulting in M 7a1, M 7a2 and M 7b (Fig. 16); female (D), right forewing M with six primary branches, with M 2 and M 6 forked, resulting in M 2a and M 2b, M 6a and M 6b from which an incomplete vein derives (Fig. 17), left hindwing M with three primary branches and then a M 4 bifurcation originating directly in the M vein, resulting in M 4a and M 4b (Fig. 18); female (E), right forewing M with seven primary branches, with M 6 and M 7 forked, resulting in M 6a and M 6b, M 7a and M 7b and an incomplete vein drifting from the areola postica (Cu A1) (Fig. 19), left forewing M with seven primary branches, with M 7 three branched arc shaped in equal parts, resulting in M 7a, M 7b and M 7c, (Fig. 20), right hindwing M with five primary branches (Fig. 21).
