Three-striped Skimmer


  • scientific: O. kollmannspergeri Buchholz, 1959; O. taeniolatum sensu Longfield, 1936 nec (Schneider, 1845)

Type locality: Somalia, no locality data available.


Male is similar to O. chrysostigma 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) metepimeral carina often largely marked with black line. Dorsal carina of Abd (narrowly) black; (d) hamule without ridge and/or hook is placed at its end, profile of hamule thus has 2 points (1 if lobe is low), hook being anterior one; (e) hook of hamule turned outward. However, differs by (1) ranging from Sahel region to Somalia; (2) smaller size, Hw 25-28 mm; (3) membranule whitish; (4) Pt 2.5-3 mm; (5) both mesepimeron and metepimeron with whitish stripes; metepimeral carina not marked with black.); (6) lobe of hamule enveloped by base of hook.
