Wroughtonia alba
(
Chou et Hsu, 1998
)
,
comb. nov.
Helcon albus
Chou et Hsu, 1998
: 295
–296.
Comparative diagnosis.
Similar to
W. zhejiangensis
, but
W. alba
has vein 1r-m of hind wing about as long as vein 1-M, the ventral protuberance of the hind femur wide (narrow in
W. zhejiangensis
), the precoxal sulcus shallow and without rugae (distinctly impressed and with rugae) and the hind coxa is reticulate dorsally (sparsely punctulate).
Host.
Unknown.
Distribution
.
China

Taiwan

Notes.
Helcon albus
Chou et Hsu
from
Taiwan
is included in
Wroughtonia
, because it has a wide obtuse ventral protuberance on the hind femur, the hind tarsus is pale and the antenna has a white band. The species is included provisionally in the key on basis of the original description, because the
holotype
(and only known specimen of
W. alba
) was not available for examination.
Spasskia anastasiae
Belokobylskij
from Far East
Russia
is included in
Wroughtonia
(as other
Spasskia
spp.) but is not close to the other species because of the obtuse ventral protuberance of the hind femur and the shape of the first tergite and of the occipital carina. In the key it will come near
W. alba
because the hind coxa are densely sculptured (transversely rugulose to rugose) dorsally; differs from
W. alba
by the complete dark brown or black antenna (with white band in
W. alba
), palpi dark brown basally (brownish yellow), temple and vertex densely and coarsely punctate-rugose (smooth) and hind coxa dark brown or black (brownish yellow).
