Taxonomic note.
Draudt (1937)
reported the
type
material of
Acronycta agnata
: "In kleiner Anzahl vom Hoeng- Shan (Prov.
Hunan
), Anfang Mitte
April 1935
.", but there are no specimens with date
April
1935
in
ZFMK
collection. At the same time, the box with specimens determined as
agnata
in
ZFMK
collection is supplemented with an additional label "
Type
verloren" [
Type
lost]. Obviously, the
types
of
Acronycta agnata
, as well as the most part of the collection of M. Draudt, which was located in Darmstadt,
Germany
, have been destroyed during the Second World War. Because of
A. digna
and its closest relative
A. metaxantha
have overlapping geographic ranges in
China
, the
neotype
designation is necessary. Here we designate as a
neotype
the topotype specimen from
ZFMK
collection determined as
agnata
(
Figs. 6
,

).
