As usual, it never stopped flying to perch and I could only get a few poor quality photos.
I am not sure about this at all. This one appears to be a new species for me. Even though I know it is very unlikely to be a Slender Clubskimmer, the abdominal pattern seems to be in line with that species. If it is in the genus, I'm going to guess that it is more likely a Paleface Clubskimmer.
