Thanks Xespok.
Any idea of genus and species?

Could be a female Urothemis edwardsii (libellulidae)...

Hi,
This is a female of the genus
Orthetrum (or possibly the closely related
Nesciothemis - I wouldn't like to suggest a species though because there are several similar
Orthetrum species in Africa and I don't have any information on species in Tanzania.

Thanks Roy.
What makes you say that contrary to Philippe's suggestion?

The vein structure in the forewing rules out
Urothemis which have only 6-8 antenodal cross veins (the dragonfly in your photo has 12) + both sexes of
U. edwardsii should show a dark patch at the base of the hindwing. The position of the arculus - which is in line with the second antenodal vein - points to
Orthetrum.
Roy.
