143. Phyllothemis eltoni (Fraser, 1935)

Number: 143
Family: Libellulidae
Genus:  Phyllothemis
Species:  Phyllothemis eltoni
Common name(s): N/A

Thai name(s): แมลงปอบ้านเอลตัน
Habitat: Small natural uplands pond
Province(s) sighted: Nam Nao environs (Petchabun).
Sightings (by me): Rare
In flight (that I have seen): July (though must be longer)


A few weeks back, I saw T. irregularis for the first time in Khao Yai. That meant I had photographed both species in the genus... except male T. irregularis. Then at the same pond as the two previous posts (144/145), I saw, what I didn't think was male, T. irregularis simply because of the colour / markings. However, there are many differences with this specimen that don't seem to match either species. As it turns out, I was correct that it wasn't T. irregularis... however, it isn't even that genus. It is, in fact, a rare specimen indeed... Phyllothemis sp. It is probably P. eltoni, but could be another similar species.

The male
The male is black with blueish markings on both the thorax and the abdomen. The wings are hyaline, stigma black. The markings on both the abdomen and the thorax are very distinct. 







Many thanks to Noppadon Makbun for the ID.
