Description
.
Adult
(
Figs. 1–6
). Wingspan 12.5–20.1 mm.
Head
: Covered with grey brown-tipped scales, sometimes uniformly ochreous to dark yellow, frons light, off-white; thorax and tegulae brown to black; labial palpus light brown, with a few black scales at base, inner surface light, off-white segment 2 slightly broader, about as long as segment 3; antenna of male slightly thicker than antenna of female, scape dark grey with narrow white apical ring, antennal segments brown with narrow white basal rings.
Thorax
: Forewing brown mottled with black especially along costal margin from base to 2/3, base with black pattern of irregular shape, three indistinct black dots in cell, sometimes small white dot at ¾ of costal margin, cilia grey, black-tipped; hindwing and cilia grey. Variation. Rather variable species. Ground colour of forewing varies from light brown to grey; veins sometimes mottled with orange; black pattern along costal margin sometimes divided in 2–3 black diffuse spots, well developed or nearly merged with ground colour.
Abdomen
: Male genitalia (
Figs. 17–19
) with uncus narrow, weakly prolonged, covered with strong setae, socii developed, longer than uncus, sub-ovate; gnathos long, strong, comparatively thick, weakly curved, slightly broadened before apex, with pointed tip; valva digitate, slightly exceeding the top of uncus setae, inner margin with short triangular tooth before half length, distal half broadened, haired, apex rounded; sacculus broad at base, distal portion moderately broad, outer margin finely serrated, tapered after 2/3 length, nearly reaching middle of valva; vincular lobes terminated into narrow projections that are curved inwards, anteromedial emargination broad and deep; saccus comparatively long, rounded; phallus short, base swollen, distal portion short with three small teeth, apex with two transverse arms. Variation. Two males from
Cameroon
and
Tanzania
with additional arm on the apex of the phallus; subapical teeth may be partially or completely reduced. Female genitalia (
Figs. 26–28
). Segment VIII sub-rectangular, weakly narrowed apically, evenly sclerotized, densely covered with fine microtrichia, with narrow digitate posteromedial sclerite, two narrow folds extending distally from base of apophyses anteriores, posterior margin straight, anterior margin strongly sclerotized with paired sub-triangular projections joint medially; apophyses posteriores very long and narrow, apophyses anteriores broad at base, distal portion narrow, straight, slightly longer than segment VIII; antrum broad, rounded, with broad v-shaped internal sclerite, ductus bursae of even width and abrupt transition to globular corpus bursae; signum at bottom of corpus bursae, prolonged serrated plate with broad ridge inside.

Remarks.
Due to the considerable variation in the wing pattern
A. exoenota
may be confused with the other
Armatophallus
-species. The head that is usually lighter than the forewing and thorax is the most constant character to distinguish
A. exoenota
from related species. The male genitalia are close to those of
A. crudescens
but differ from this and other species in the presence of well developed socii; a broader sacculus and differently shaped arms at the tip of the phallus are additional characters that distinguish
A. exoenota
from
A. crudescens
. The female genitalia are similar to those of
A. crudescens
but the ductus bursae is longer and narrower, the sclerotized plate in the antrum is bigger, the distal narrow portion of the apophyses anteriores is shorter, segment VIII lacks sclerotized patches and the signum is narrower and longer.
A. exoenota
is an externally rather variable species widely distributed in Africa. The specimens from
South Africa
and
Namibia
(including the
holotype
) differ from the specimens from Eastern and Western Africa in the dark, uniformly brown forewing with poorly expressed black markings. No significant differences in the genitalia were observed, except for the number of arms and teeth on the apex of the phallus. Specimens from
Tanzania
and
Cameroon
have three arms in contrast to two arms in specimens from
South Africa
. However the third arm may be merged with the distal portion of the phallus in some specimens and then is hardly visible; moreover, the arms differ in length. It is possible that specimens from
Cameroon
with a well developed third arm represent a separate species, but we prefer to treat them here as
A. exoenota
until their status can be assessed by the study of additional specimens.
G. xylophaea
was described from three females collected in Umwuma (
Zimbabwe
) and Woodbush Village (Transvaal,
South Africa
). The female from the last locality does not bear a
type
label. The
holotype
and both
paratypes
differ externally from the
holotype
of
exoenota
in having a lighter, grey forewing with well expressed black pattern along the costal margin. However, the female genitalia of the
holotype
of
G
.
xylophaea
agree in all details with those of
exoenota
so that there can be no doubt about their synonymy.
