|Epiophlebia superstes (Selys, 1889)
is a species of dragonfly that is native to Japan.
The genus Epiophlebia is the sole
member of the family Epiophlebiidae, which is itself the sole living representative
of the Epiproctan infraorder Epiophlebioptera, and it contains only three
species. They are relict species of a once widespread group. The first
two species, Epiophlebia superstes and Epiophlebia laidlawi, were historically
placed in their own suborder Anisozygoptera, considered intermediate between
dragonflies and damselflies, mainly because the hind wings are very similar
in size and shape to the forewings and held back over the body at rest,
as in damselflies. It has more recently been recognized that the genus
Epiophlebia shares a more recent ancestor with dragonflies (having become
separated from these in and around the uplifting of the Himalayas), and
the group has accordingly been reclassified as an infraorder within the
dragonflies. Very recently a third species, Epiophlebia sinensis, have
been described from Heilongjiang province in northeast China, bridging
the Epiophlebia distribution gap between Nepal and Japan.
The length of Epiophlebia superstes
is 45 mm to 53 mm. It has black body with bright yellow stripes on the
thorax and abdomen. Epiophlebia superstes is native to Japan and is distributing
it in the headwaters widely in Kinki area. The flight period of Epiophlebia
superstes in Kinki area is from the end of April to mid June.
Epiophlebia superstes lays eggs to
the plant that is in a higher position than the surface of the water.
The prolarva that hatched repeats a jump and arrive on the water. Until
it reaches on the water it does not become a first instar larva. The time
of the prolarva is a dozens minute from several minutes. The period of
the prolarva is longer than other dragonflies.
