243: Anisopleura furcata Selys, 1891

 Number: 243 / Family: Euphaeidae / Genus: Anisopleura
Species: Anisopleura furcata Northern Notch-wing Streamglory*
Province(s) sighted: Chaing Mai
Habitat: Forested Streams 
In flight: July / Sightings (by me): Rare
Species easily confused with: N/A

*As there is no common name, even for the genus, I decided upon 'Northern Notch-wing' as it ties in with the Thai name and I raised the name 'Streamglory' for the genus Anisopleura. If you can think of better, let me know.

When I returned to Doing Inthanon, Chiang Mai for the first time in well over a decade, there was one species that kept on cropping up on other searchers' checklists, was Anisopleura furcata. And oddly, other than a few very common species, it was the first 'special' one to show at Sirphum Waterfall. It was still fairly early in the morning, but one had decided to show and was warming up the early morning sun. It was amazing to see and I was so happy! It was my first 'new species' for the entire trip. I ended up seeing 7-8 specimens in total including male and female.

The Male
This is a younger male and I saw 2-3 of them in the long grass a little away fro the water. It is a very robust species for a damselfly and has unique appendages.



The 'Old' Male
Here is a mature male and was the first one I saw, basking in the early morning sunshine.


The 'Old' Female
This female looks quite old and was set back a good distance from the stream.
