Diagnosis.
Dargida mocoides
comb. nov.
slightly resembles
D. phaeoneura
and its ally species mentioned in the diagnosis above.
Dargida mocoides
can be easily distinguished by its ochre forewing ground color, with grayishsilver areas through the costal area, first 1/4 of 2A, and outer margin extending proximally over veins R
5
, M
1
, CuA
1
and CuA
2
. In
D. phaeoneura
and ally species the forewing ground color is light brown, with areas of different coloration, but never grayish-silver. The male genitalia of
D. mocoides
is very similar to
D. phaeoneura
, differentiated by a cucullus of 2/5 the length of valva and point-ended digitus, whilst in the latter the cucullus has a length of 1/3 the length of valva and the digitus is rounded ended.
Redescription.
Head
: densely covered by pale ochre scales; antennae light brown dorsally; labial palpi and eyes as in
D. radiata
.
Thorax
: patagia rust-brown; tegulae, thorax, and legs ochre, gradually lighter posteriorly; legs as in
D. radiata
.
Forewing
: male
14.5 mm
(n=2), female
15.8 mm
(n=1); wing shape as in
D. radiata
.
Dorsal
: ground color ochre, paler along discal cell and M
1
extending to last 1/3 of R
5
and along CuA
2
–2A, below anal fold; costal area and first 1/4 of 2A light grayish-silver; outer margin with a continuous grayish-silver band extending over veins R
5
, M
1
, CuA
1
and CuA
2
, followed proximally by a discontinuous black stripe between R
5
and 2A; rust-brown stripes on R
4
–R
5
, R
5
–M
1
(surrounding first 2/3 of R
5
), bordering anteriorly CuA, from origin of CuA
2
to M
2
–M
3
, and bordering posteriorly CuA, from base to near origin of CuA
2
, vanishing along CuA
2
, and at about the center of the anal area (between 2A–anal margin); basal dash just posterior to the origin of CuA
2
; postmedial arch-shaped row of black rounded spots between R
5
and anal margin; outer line rust-brown; fringe pale yellow basally and apically, pale rustbrown medially.
Ventral
: ground color lustered brown, darker at center; outer line narrower than dorsally; fringe lighter than dorsally.
Hind wing
: wing shape as in
D. radiata
.
Dorsal
: mostly translucent pearly cream, suffused by light brown scales along costal and outer margins; fringe as in dorsal forewing but with median rust-brown line reduced.
Ventral
: similar to dorsal but more uniformly pearly cream.
Abdomen
: ochre, slightly darker than dorsal thorax, with a black thin line along pleura.
Male genitalia
(
Figs 32
,
37
): tegumen, ventral tegumen arm, dorsal projection of saccus, saccus, uncus, subscaphium and transtilla similar to
D. phaeoneura
. Valva about six times as long as wide (at widest part), wider at the base then slightly narrower, dorsal margin strongly concave at the middle, ventral margin slightly convex, disto-ventral margin angled; sacculus with meso-dorsal margin about angled and extending beyond base of costa and transtilla; costa uniformly narrow, dorsal margin strongly concave; costal process reduced, slightly sclerotized, not projected beyond apex of valva, fused with digitus; ampulla spear-like, curved proximally, margins straight, about 1/3 as long as cucullus, base wide tapering to a pointed end; clasper as a small triangular projection at base of ampulla; digitus perpendicular to valva, about straight, as long as ampulla, base wide narrowing distally to a pointed end; sensory plate not observed; cucullus 2/5 the length of valva, dorsal margin convex, proximal 2/3 narrow, increasing in width distally, distal half triangular, about twice as wide as the mid width of valva, disto-ventral projection longer and narrower than disto-dorsal projection, corona uniseriate, extended throughout apical margin, four ventral setae wider, strongly sclerotized, the two ventral most setae tooth-like. Fultura inferior broken (cannot be observed). Aedeagus thick, shorter than valva, slightly arched ventrally (the distal part of the aedeagus broken apart); vesica not completely distended, apparently bearing two groups of cornuti.
Female genitalia
: not analyzed (the only two known females could not be dissected).

Etymology.
Although not mentioned by the author, the name probably is a rearrangement of the letters of
Leucania commoides
Guenée
, a species compared by the author with
D. mocoides
in the original description (
Dognin 1897
).
Distribution.
Dargida mocoides
is another Andean member of the genus, only known from a few specimens collected in the Ecuadorian province of
Carchi
in the north, at
3200 m
of elevation, and
Loja
(
type
locality) in the south, at around
2200 m
(
Fig. 43
).

Comments.
This rare species is only known from a handful of specimens collected in the northern and southern Andes of
Ecuador
, above
2000 m
of elevation.
Dargida mocoides
was described by
Dognin (1897)
in
Leucania
, combined with
Cirphis
Walker
by
Draudt (1924)
, and returned to
Leucania
by
Poole (1989)
where it is currently. However, the wing pattern and the morphology of the male genitalia point it to as a member of
Dargida
(
comb. nov.
).
