Diagnosis.
Synanthedon phoenix
sp. nov.
is somewhat similar to
S. tenuis
(Butler 1878)
from
Japan
,
Korea
, Far East
Russia
, and eastern
China
, but can be distinguished from
S. tenuis
by metathorax of female yellow instead of black tinged with blue sheen. Superficially,
S. phoenix
also resembles to
Ravitria confusa
(Gorbunov & Arita 2000)
, but scales of anal tuft are black in
S. phoenix
, but yellow in
R
.
confusa
. Phallus of
S. phoenix
bears one strong tooth ventro-distally, which is absent in
S. tenuis
. Male of
R. confusa
is unknown.
Etymology.
A creature from Greek mythology,
phoenix
=
phoenix
.
Biology.
The larva bores into the stem or trunks of
1−2 cm
in diameter of
Quercus longinux
(Fagaceae)
and feeds on callus tissue around the entrance hole, which is covered with silk, debris, and frass.
Distribution.
Known only from
Taiwan
.
