Two New Records of Ennominae Species (Lepidoptera: Geometridae) from Korea

Abstract

Two ennomine species, Amblychia angeronaria Guene and Peratostega deletaria (Moore), are reported for the first time from Korea. Amblychia angeronaria was collected from Isl. Gageo-do, in the south west of Korea. The species is distinguished by the large wingspan, the ochreous forewing with a row of large white dots on the postmedian and a grayish apical dot, and the grayish or dark ochreous hindwing with undulating postmedial line and dark grayish subterminal line. Peratostega deleraia was collected from Isl. Jeju-do, and can be distinguished by the dark brown forewing with a blackish dentate postmedian and a light brown apical dot, and the dark brown hindwing with the light brown subtermen and angulate termen. Diagnosis and description of the species are given along with figures of the male and female genitalia.

INTRODUCTION
Genus Amblychia Guenée was established, based on Ambly-
chia angeronaria Guenée as the type species, and comprises
about 20 species mostly from the Indo
-
Australian region
(Holloway, 1993; Scoble, 1999). The species of Amblychia
show gray
-
brown wing ground color with a mixture of strai-
ght and crenulate fasciae, strongly angular and excavated
margin to the hindwing (Holloway, 1993). The male geni-
talia of Amblychia have a bifid uncus, strong and apically
rugose gnathos, rhomboidal valva with short and long hair
-
setae on the costa and the aedeagus with a small lateral thorn
subapically. The female genitalia of Amblychia have the
strongly sclerotized, curved ovipositor lobe, densely scaled
membranous pair of lobes on the lamella postvaginalis, the
short and sclerotized ductus bursae and the large corpus bur-
sae with a dentate signum(Holloway, 1993).
Genus Peratostega Warren was designated, based on Pera-
tostega coctata Warren as the type species, and comprises
four species from northern India, Borneo and Japan(Scoble,
1999). Peratostega species show filiform male antennae and
dull reddish brown wings(Holloway, 1993). The male geni-
talia of Peratostega have a single coremata on valva, the
short and triangular valva with double spurs from sclerotized
ventral angle, the short saccus, the small aedeagus with a
broad scobinate band on the vesica. The female genitalia
have the crescent
-
shaped lamella antevaginalis, the narrow
ductus bursae, the pyriform corpus bursae with a straight
bifid or bilobed flange(Holloway, 1993).
In the present study, two ennomine species, Amblychia
angeronaria Guenée and Peratostega deletaria are reported
for the first time in Korea. More than 10 specimens of Ambly-
chia angeronaria were collected at the most southwestern
island of Korea, Gageo
-
do, and two specimens of Peratos-
tega deletaria were collected at the southern slope of Mt.

ABSTRACT
Two ennomine species, Amblychia angeronaria Guenée and Peratostega deletaria (Moore), are reported for
the first time from Korea. Amblychia angeronaria was collected from Isl. Gageo
-
do, in the south west of Korea.
The species is distinguished by the large wingspan, the ochreous forewing with a row of large white dots on
the postmedian and a grayish apical dot, and the grayish or dark ochreous hindwing with undulating post-
medial line and dark grayish subterminal line. Peratostega deleraia was collected from Isl. Jeju
-
do, and can
be distinguished by the dark brown forewing with a blackish dentate postmedian and a light brown apical dot,
and the dark brown hindwing with the light brown subtermen and angulate termen. Diagnosis and description
of the species are given along with figures of the male and female genitalia.

Diagnosis. This species is characterized by the long pecti-
nations of the male antennae, the larger wingspan, a row of
white triangular dots on the postmedian fascia of forewing,
a dark brown medial line and blackish discal dot on fore
and hindwings and undulating postmedial line of hindwing.
The male genitalia can be distinguished by the strongly taper-
ed and apically bifid uncus, the large spatulate gnathos, the
large and rounded juxta, and the membranous and apically
projected valva, with large setae
-
like hairs on the costa and
cucullus. The female genitalia can be distinguished by the
long and medially curved ovipositor, the long and sclerotized
apophyses, the broad antrum, the short ductus bursae, and
the long membranous corpus bursae with a rounded signum
with dentate margin.
