Diagnosis
.
Asclerobia sinensis
is characterized by the light yellow forewing and almostthe same non-prominent ante-medial line that is edged inwardly with yellowish-red raised scales, and a distinct grey streak along the costal margin of the forewing. The male middle segments of antenna are elongated in width, 2× as wide as long (
Fig. 20c
), in
A. alexandrae
sp. nov.
middle segments of antenna almost square, 1.3× as wide as long. In male genitalia, presence of editum on the valva in combination with apically rounded saccus is characteristic. In
A. tchahabarella
the editum is absent.
Asclerobia alexandrae
has the apex of the saccus almost truncate. In female genitalia the length of VIII segment is 1.5× its width (2.2× its width in
A. alexandrae
sp. nov.
), the papillae anales are short and have a lateral recess (longer and straight in
A. alexandrae
sp. nov.
).
Note
.
Roesler (1969)
writes that the ductus bursae of the female genitalia has no sclerotization. However, in his preparation of this female (
Fig. 26
) we can see sclerotization of antrum.
Remarks
.
Sclerobia sinensis
Caradja, 1937
was described based on a single male from “Taishanmassivs, Provinz Shantung” [Tai Shan or Mount Tai,
Shandong prov.
, E
China
] collected by Höne. This specimen was designated as the
holotype
by Roesler, who illustrated the male genitalia (GU–5855
♂
, U. Roesler; ZFMK). Female genitalia (GU–5872
♀
, U. Roesler; ZFMK) of the specimen from the type locality collected by Höne, was illustrated in
Roesler (1969: 247
, figs 1–2). Another male from the type locality also collected by Höne is deposited in SMNK, its genitalia (gen. slide: M. Horak prep. no. 11004) are illustrated here (
Fig. 30
).
Asclerobia gilvaria
Yamanaka, 2006
was described based on specimens of both sexes from
Japan
(
Hokkaido
and Honshu). The species was considered closely related to
A. sinensis
, but some differences in male genitalia (broader gnathos, larger editum and narrower juxta) and stronger sclerotized antrum and larger numbers of thorns on the wall of corpus bursae in the female genitalia were treated as diagnostic characters for separating
A. gilvaria
from
A. sinensis
(
Yamanaka 2006: 181
)
.
Streltzov (2010)
, based on study material from
Russia
Far East, argued that all diagnostic characters of
A. gilvaria
mentioned by Yamanaka are variable. Based on these findings Streltzov (ibid.) synonymized
A. gilvaria
with
A. sinensis
.
Biology
. It is known that at least
one specimen
from the
type
locality (SMNK), was collected at an altitude of
1550 m
in mid-May. In
Afghanistan
, the specimens were collected at an altitude of 1100 and
2700 m
in April and late June (
Amsel 1970
). In
China
, the known host plants are
Caragana korshinskii
Kom.
(
Zou
et al.
1989
) and
Caragana microphylla
Lam.
(
He & Huang 2010
).
