Orthetrum ransonnetii diagnosis

Desert skimmer (Orthetrum ransonnetii) made it onto the Western Palearctic list in 2007, just too late to be included in KD's field guide. I recently found one in northern Oman and offer you this brief photo comparison with Orthetrum chrysostigma to aid identification.

Orthetrum ransonnetii - note the white hind wing membranule, lack of waist and dark subcostal crossveins.

Orthetrum chrysostigma - note the dark membranule with small adjacent yellow border in the hindwing, the waisted abdomen and the pale subcostal crossveins.
