Diagnosis. As described by García Aldrete in 2004

Male. As described by García Aldrete in 2004

Female. Color. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 10 ). Scape brown and pedicel brown, f1–f3 pale brown. Mx4 pale brown, with apex white. Femora brown; tibiae pale brown with distal ends brown; tarsomeres 1–3 pale brown. Forewings ( Fig. 11 ); almost hyaline, pterostigma with small pale brown bands basally and distally; a brown spot at confluence of CuP-1 A, veins brown. Hindwing hyaline; veins brown ( Fig. 12 ).

Morphology. Compound eyes without interommatidial setae ( Fig. 10 ). Outer cusp of lacinial tip broad, with five denticles ( Fig. 13 ). Forewing pterostigma elongate, wider in the middle, narrowing at the ends; areola postica tall, with round apex; Rs straight, 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 ( Fig. 11 ). Hindwing Rs and R 2+3 straight, R 4+5 slightly recurved; M vein with four primary branches ( Fig. 12 ). Subgenital plate broad, with sides converging to a pointed apex, pigmented area wide, V shaped, setae as illustrated ( Fig. 14 ). Ninth sternum ( Fig. 15 ) broad, almost square, basally with a strongly pigmented area, arch shaped, on each antero-lateral corners; distally with a strongly pigmented area sinuous, on each postero-lateral region, with a membranous convex apex in the middle. Gonapophyses: v1 long, with outer margin heavily sclerotized, wider in the middle and narrowing at the ends, with acuminate apex; v2 +3 stout, with pointed proximal heel, with four large setae on outer lobes as illustrated, distal process stout, short, distally blunt, with a field of microsetae ( Fig. 16 ). Epiproct almost semicircular, three setae medially, other setae as illustrated ( Fig. 17 ). Paraprocts broadly elliptic, sensory fields with 26 trichobothria on basal rosettes, setae as illustrated ( Fig. 17 ).

Measurements (in microns): FW: 4479, HW: 2916, F: 1353, T: 1921, t1: 808, t2: 90, t3: 160, f1: 862, f2: 678, Mx4: 323, IO: 536, D: 428, d: 266, PO: 0.62.

Variation in the fore- and hindwing veins in two male specimens. García Aldrete (2004) described the fore- and hindwing veins of the holotype of L. maracaensis as anomalous and asymmetric: right forewing with an incomplete vein arising from Cu 2 and M vein with six primary branches, with M 6 forked resulting in M 6a and M 6b; left forewing with M vein with five primary branches, with M 5 three branched and one of the veins incomplete; right hindwing M with five primary branches and left hindwing M with three primary branches, with M 1 distally branched, resulting in M 1a and M 1b.

Two male specimens collected in 2016 in the Brazilian state of Roraima show the following variations: a male (male A) with right forewing with M with six primary branches, with M 4 and M 6 forked, resulting in M 4a, M 4b, M 6a and M 6b ( Fig. 18 ); left forewing with the same pattern as the right forewing of the holotype, but without an incomplete vein arising from Cu 2 ( Fig.19 ); in right hindwing M with four primary branches ( Fig. 20 ) and in left hindwing M with three primary branches and without secondary branches ( Fig. 21 ); another male (male B) with right forewing with the same pattern as the right forewing of the holotype, but without an incomplete vein arising from Cu 2; in left forewing M with six primary branches, with M 6 three branched, resulting in M 6a, M 6b1 and M 6b2 ( Fig. 22 ), right and left hindwings with the same pattern as the right hindwing of the holotype.
