181: Gynacantha basiguttata Selys, 1882

Number: 181 / Family:  Aeschnidae / Genus: Gynacantha     
Species: Gynacantha basiguttata / Spoon-tailed Duskhawker   
Habitat: Forested ponds  
Province(s) sighted: Chaiyaphum  
In flight: July / Sightings (by me): Rare (two males)  
Species easily confused with: Gynacantha saltatrix; Gynacantha bayadera

There are definitely several species of Gynacantha that reside in Phu Khieo WS, but they are incredibly difficult to locate. That's why I was really happy to spot three species in one day, one of which is a new species for my records in the shape of Gynacantha basiguttata. Known commonly known as the Spoon-tailed Duskhawker, it is a large species that I spooked out of his hiding place which was deep inside tall reeds overhanging a temporary pool. Incidentally, the other two species I saw were G. subinterrupta (a first for me here) and G. saltatrix (another first for the place). According to the records, G. bayadera is also present and Noppadon Makbun believes G. phaeomeria to be there also. Seeing all five species there would be amazing. Hopefully one day, especially if I keep trawling the little swampy ponds all the time. I have seen two males, so assume it is quite rare/hard to find.

The Male
The fully mature male is rather beautiful with a green head, a green-blue thorax and greenish markings along the abdomen. It is a large species and incredibly skittish, but the key to ID is the 'spoon-shaped' appendages which give it its common name.
