Comments.
Platyxantha chinensis
was included in the review of the genus
Fleutiauxia
Laboissière, 1933
by
YANG (1993)
. However,
REID (1999)
transferred it to
Taumacera
which was followed by
BEENEN (2010)
in the Palaearctic catalogue.
YANG et al (2015)
included this species in
Fleutiauxia
again.
Based on the original description,
MAULIK (1933)
described
Platyxantha chinensis
from
30 specimens
and the type was supposed to be in the BMNH. There is a series of four specimens in the BMNH placed in the genus
Fleutiauxia
, however, none of the specimens bear Maulikʼs original identification label. Because the label data and habitus of the specimens agree with the original description, I consider them as the original type series of
Platyxantha chinensis
(
Fig. 105
) and all must have status of
syntype
as no specimen is labelled as the type. The only discrepancy is between the collecting date on the labels (
25.iv.1933
) and the one given in the original description (
23.iv.1933
). In my opinion this inconsistency can be easily explained by the pin hollows as each label was punctured in the position of the number 5 and at first glance the number could be easily misinterpretad as 3.
Based on the open posterior margin of the procoxae I confirm that
YANG (1993)
and
YANG et al. (2015)
correctly placed
Platyxantha chinensis
in
Fleutiauxia
. Moreover, study of a
paratype
of
Fleutiauxia mutifrons
Gressitt & Kimoto, 1963
(
Fig. 106
) clearly showed that both taxa are conspecific (both were described also from the same type locality: Hangchow). Thus, I synonymize
Fleutiauxia mutifrons
with
F. chinensis
.
