Diagnosis
.
Asclerobia tchahabarella
is characterized by the yellowish-brown forewing, the yellow-brown antemedial line with bright brown raised scales, and the distinct grey irroration in distal 2/3 along costal margin to about 1/4–1/3 width of the forewing. For the differences from
A. alexandrae
sp. nov.
and
A. sinensis
see the differential diagnosis above presented under those species. In male genitalia, valva without editum (the related species have the editum), the rounded and widened apically saccus (not widened in
A. sinensis
) is characteristic. The saccus in
A. alexandrae
sp. nov.
is truncate. Female genitalia are unknown.
Note
. In the original description,
Amsel (1950)
did not mention the valval editums and did not draw them, but in the subsequent paper (
Amsel 1970
) he claimed their presence in a specimen from
Afghanistan
. From the photographs of the slide of the male genitalia of this specimen (GU
♂
4218 by
Amsel 1970
: fig. 34) it follows that the presence of valval editums is confirmed. This confirmation justifies the assignment of this specimen (and other records from E
Afghanistan
) to
A. sinensis
, but not to
A. tchahabarella
. Also,
Asselbergs (2007)
published a drawing of the male genitalia of
A. tchahabarella
without editums, which confirms the absence of these structures in
A. tchahabarella
.

Remark
.
Salebria tchahabarella
was described based on
two males
and
one female
from “Bender Tchahbahar” [Chabahar], with illustration of the male genitalia (
Amsel 1950: 254
, fig. 18). The specimen labelled: “
Iran
Baloutchistan | Bender Tchahbahar |
22 Dezember 1937
| Coll. Brandt” || “GU. | 795a” || “
Salebria
tchah- | baharella Ams. | det. H. Amsel” || “Typus
♂
| leg.H.Amsel” || “2:76 | R.M. prep. | 3113” || “NHRS-TOBI | 000004936” (
Fig. 5
) is designated here as the
lectotype
of S.
tchahabarella
,
and another
two specimens
should be considered as
paralectotypes
. The
lectotype
and the
paralectotype
labeled as female, without abdomen, (
Fig. 6
) are kept in NHRS. One more
paralectotype
is kept in SMNK.
Amsel (1970)
transferred
tchahabarella
to
Oligochroa
Ragonot, 1888
, which was synonymized with
Faveria
Walker, 1859
(
Shaffer
et al.
1996: 176
). Male genitalia clearly indicate the assignment of
Salebria tchahabarella
to the genus
Asclerobia
rather than to
Pempelia
Hübner, 1825
as it was proposed by
Asselbergs (2007)
without any argumentation. Hence, the following combination is established:
Asclerobia tchahabarella
(
Amsel, 1950
)
comb. nov.
Note
. An Iranian city—the
type
locality of
Asclerobia tchahabarella
, is often transliterated into English as Chabahar, and into German as Tschahbahar. But since the chapter Etymology is absent in the original description, and there is no explicit explanation for the formation of the species-group name in the text of the original description, we cannot be sure whether the name “
tchahabarella
”, was a spelling mistake or not. It might be the transliteration into the Latinized form of a word originating from the city name in Persian made by
Amsel (1950)
. Therefore, following article 32.5.1 of the ICZN which sounds as follows: “Incorrect transliteration or Latinization, or use of an inappropriate connecting vowel, are not to be considered inadvertent errors”, we consider that there is no necessity to correct the spelling of this species-group name in the present revision and in future treatments.
