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.
