Sinictinogomphus clavatus


Taxonomy [top]

Kingdom Phylum Class Order Family

Scientific Name: Sinictinogomphus clavatus
Species Authority: (Fabricius, 1775)
Common Name(s):
English Golden Flangetail
Ictinus phaleratus Sélys, 1854
Taxonomic Notes: Fraser (1939) established the genus Sinictinogomphus to receive clavatus and synonymised Ictnius phaleratus Sélys 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 Hämäläinen and Pinratana (1999) recognise the subspecies Sinictnogomphus clavatus phaleratus Sélys 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.
