Orthetrum camerunense Gambles, 1959
One-striped Skimmer


  • scientific: O. caffrum (Burmeister, 1839) ssp. camerunense

Type locality: Bamenda, Cameroon


Male is similar to O. caffrum by (a) thorax with 1-3 contrasting whitish stripes on each side, each one with dark border on anterior or both sides; (b) when stripes are faint or invisible due to pruinosity, then labium and labrum all pale, lobe of hamule low and Abd always shorter than Hw; (c) wings clear around nodes; (d) metepimeral carina at most with posterior corner marked with black. Dorsal carina of Abd without black; (e) mesepimeral whitish stripe lies against humeral suture; (f) hook of hamule turned forward, lobe rounded. However, differs by (1) ranging from W Kenya to Katanga and Cameroon; (2) only stripe on mesepimeron distinct; that on metepimeron may be hinted by whitish wash, but is not dark-bordered; (3) yellow at Hw base deep, extends at least halfway to Cux and into several cells of anal field; (4) hook of hamule with raised posterior border.
