Orthetrum ? guiñéense Ris (1909) Records : Campion (1923) (Scabra & Snell): a dubious record since at that date there was much confusion in this and other species of the genus. I suspect it may have been julia. Orthetrum julia Kirby (1900) All the many specimens I saw both alive and in the Brigada collection were the nominotypical race julia. This was the commonest species of 6°40' Morro Peixe. Säo Tomé Fig. 4: Säo Tomé.
