Diagnosis.
This new species is one of the largest species (wingspan
19 mm
) of the genus in Africa. It is nearly of the same size as
L. corythaeola
Meyrick, 1931
which was described from
Uganda
, but it can be distinguished by the 3
rd
segment of the labial palpus which is as long as the 2
nd
segment (much longer in
L. corythaeola
; see
Meyrick 1931: 80
); the forewing with slightly convex termen (straight in
L. corythaeola
; see
Meyrick 1931: 80
); the hind wing ground color much paler than forewing, orangish-grey (concolorous with forewing, bronze), with M
3
and CuA
1
stalked for basal 1/3 (M
3
free from CuA
1
in
L. corythaeola
; see
Meyrick 1931: 80
). The male genitalia differ from those of all known species in the Afrotropical region by the following: the costal bar of valva bears a triangle median angle (see arrow no.
1 in
Fig. 5C
); the basal plate of gnathos elongates (length about twice its width), with a convex caudal margin (see arrow no.
2 in
Fig. 5C
); the aedeagus is slender, about 0.1 times slenderer than its length.
Description.
Male (
Figs 5A, B
). Wingspan 19.0 mm.
Head
: golden yellow, with light orange, erect scales laterally. Antenna broadened, only with basal part. Second segment of labial palpus thickened, yellow brown on outer surface; 3
rd
segment strongly upturned, as long as 2
nd
segment, dark fuscous.
Thorax
: tegula and thorax dark brown. Forewing ground color fuscous, evenly dark brown, without any markings; apex angulate; termen oblique, gently convex; fringe concolorous with ground color; venation with R
5
to apex; M
2
well developed; base of M
3
arising from between base of M
2
and CuA
1+2
; CuA
1
and CuA
2
short-stalked. Hind wing ground color paler than forewing, orangish-grey; apex angulate; fringe concolorous with ground color; venation with M
2
present; M
3
and CuA
1
stalked for basal 1/3.
Abdomen
: tergum VII and sternum VIII shown in
Fig. 5E
.
Male genitalia
(
Figs 5C, D
): basal lobes of uncus directed outwardly, with rounded apices; caudal margin slightly concave. Basal plate of gnathos elongated, length about twice its width, distally with convex caudal margin (see arrow no.
2 in
Fig. 5C
); median process tapering towards apex, strongly bent from beyond 2/3. Valva broad basally; costal bar with triangular median angle (see arrow no.
1 in
Fig. 5C
); cucullus elongated, as long as basal part of valva, slightly convex on both margins; sacculus broadly developed, followed by a crescent, linear plate before cucullus. Juxta jar-shape. Vinculum a broad band. Aedeagus rather slender (width about 0.1 times its length), broadened in basal 1/3; cornuti consisting of 3–4 horn-shaped spines.

Distribution.
