Diagnosis.
Head and patagia creamy. Tegulae and dorsal surface of thorax and abdomen, white. All wings silky white. In males a creamy androconial patch in the costal cell dorsally. Valvae symmetrical, longer than the uncus. Saccus evenly rounded.
FIGURES 39‒42.
Gloora sericea
comb. nov.
, male genitalia; dorsal (39), ventral (40), lateral (41), phallus (42). Scale bar: 1 mm.
Re-description. Male. Head.
Proboscis light brown. Palpi creamy, not exceeding vertex in length. First and second palpomeres with brown scales dorsally. Frons creamy, slightly longer than wide. Ocular ring brown with bluish hue. Vertex, scales immediately posterior to the antennal sockets and occiput creamy. Antennae creamy with brown scales along the shaft of flagellomere. Medial rami approximately two times the width of the shaft of flagellomere. Rami decreasing in length gradually towards the tip of the antennae. Distal flagellomeres lacking rami.
Thorax.
Patagia creamy. Dorsal surface of meso- and metathorax, including tegulae, white. Foreleg coxae creamy white on the anterior side, white on the posterior side. Foreleg femora, tibia and tarsi light brown, with white scales on the outer surface. The epiphysis light brown. Mid- and hindleg coxae white. Mid- and hindleg femora, tibia and tarsi light brown, with white scales on the outer surface.
Forewings.
Forewing length
13‒14 mm
(n = 4) (no
types
). Dorsal and ventral surfaces identical in color pattern, covered by white scales. The costal margin brown, fading towards the apex. Retinaculum white.
Hindwings.
Dorsal and ventral surfaces almost identical, covered with white scales. Presence of a creamy androconial patch in the costal cell upper side.
Abdomen.
Countertympana, dorsal and ventral side, white.
Genitalia
(
Figs. 39‒42
). Saccus developed. Tegumen narrower than vinculum, glabrous. Anterior margin of tegumen with a deep U-shaped invagination. Posterior margin of tegumen thinning, in the middle membranous, from which two structures emerge in the form of tongues, sclerotized. Uncus unilobed, acute. Juxta extended, sclerotized, basally two times wider than distally. Valvae symmetrical, longer than the uncus; in lateral view, thin and slightly curved, covered with setae. Ventral process membranous covered with setae. Dorsal process slender, slightly sclerotized and acute. Phallus widening distally. Vesica membranous with two patches of cornuti: the first in the basal area of the right side, the second in the distal area of the left side. Coremata with additional scale bunches (
Fig. 49
) at the bases of coremata tubes (as in
alba
, above).
Female.
Forewing length
14‒15 mm
(n = 2) (no
types
). As males, but medial rami as long as the shaft width. The costal margin brown, but less pronounced than males. The frenulum with two bristles.
Genitalia
(
Fig. 53
). Ninth tergite slightly sclerotized. Papillae anales with relatively long setae. Anterior and posterior apophyses subequal. Ostium and antrum centralized. Antevaginal and postvaginal lamellae sclerotized. Ductus bursae wide, flattened, sinusoid, membranous in the distal half, sclerotized in the basal half. Corpus bursae oval and membranous, with sclerotized spicules on more than half its surface. Ductus seminalis emerging from the first third of the bursa.

Distribution.
In the Southeast and South of
BRAZIL
, including the states of
Rio de Janeiro
,
Rio Grande do Sul
(
Zerny 1931
),
Santa Catarina
(
Hoffmann 1936
),
Paraná
and
São Paulo
(NHMUK).
Remarks.
Gloora sericea
is easily confused with some
Lithosiini
, including
Agylla
and
Cyptonychia flaviceps
Druce (
Hoffmann 1936
)
.
Pinheiro & Gaal-Haszler (2015)
asserted that the habitus and genitalia are certainly not part of a monophyletic concept of
Eucereon
, also mentioning that the species may be related to
Hyaleucerea mundula
,
Eucereon alba
and
E. vestalis
. With the last two they share similarities in the color of adults males and females. Greater similarities in relation to external morphology and genitalia are found with
H. mundula
and
E. alba
; for
E. vestalis
see Discussion.
Eucereon sericeum
was recently erroneously transferred to the genus
Agaraea
Herrich-Schäffer
, [1855] (
Beccacece & Zapata (2017)
which belongs to the
Phaegopterina
. The genitalia of
Agaraea
(
Beccacece & Zapata (2017: figs. 11‒14)
are very different and
E. sericeum
is a
Ctenuchina
.
