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
).

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
.
