|Sinictinogomphus clavatus (Fabricius,
1775), the Golden Flangetail, is a species of dragonfly in the Clubtail
family Gomphidae. It is the only species in the genus Sinictinogomphus.
The genus Sinictinogomphus was established
by Fraser (1939) to receive clavatus and synonymised Ictnius phaleratus
Selys with clavatus (Fabricius), which is the only other described member
of the genus. Lieftinck (1942) considered Sinictinogomphus was a synonym
of Ictinogomphus but Chao (1990) and subsequent authors have adopted Sinictinogomphus.
Asahina (1986) and Hamalainen and Pinratana (1999) recognise the subspecies
Sinictnogomphus clavatus phaleratus Selys from Thailand and Tsuda (2000)
lists this subspecies from Myanmar, Nepal and Thailand. The 'western' phaleratus
race is smaller with less extensive foliaceous flaps on abdominal Segment
8. However, since the character states overlap through its range there
appears to be little support for a distinct subspecies, Steinman (1997)
considers phaleratus is a synonym.
Sinictinogomphus clavatus is a rather
large gomphid. Both male and female have foliaceous flaps black and yellow
on S8. Female is similar to the male in color & markings.
S. clavatus is common over a large
range from Nepal to Vietnam and eastern Russia. Its habitat is standing
or still (lentic) water
It is common and widespread over
a large area, through southwest, south, central and northeast China to
Korea, Japan and southern, far eastern Russia. It is therefore assessed
by IUCN Red List as Least Concern.
