Nesocordulia spinicauda ?

( Fig. 14j )

Photographic record. Female, Palmarium Reserve , 18.606° S, 49.2118° E, Atsinanana Region, central-eastern Madagascar, 08.12.2023, photo by Michiel Van de Velde: https://www.inaturalist.org/observations/194048870 (also photographed and submitted without details by Yenthe Van Puyenbroeck: https://www.inaturalist.org/ observations/247478087).

The long cerci and the shape of the yellow spots on S7 and on the synthorax (the latter poorly visible) suggest N. spinicauda , but that species’ diagnostic yellow markings on S8 are not apparent, while other informative features are not visible.
