Orthetrum monardi Schmidt, 1951
Woodland Skimmer

Type locality: Bissau, Guinea-Bissau

Diagnosis

Male is similar to O. microstigma by (a) thorax without whitish stripes; (b) Pt usually shorter than 3 mm, 9.5% of Hw length or less; (c) membranule dark; (d) Hw base with yellow or amber patch; (e) lobe of hamule very low and obtuse, space between it and hook at most right-angled notch. However, differs by (1) being restricted to savanna and woodland; (2) smaller size, Hw 25-31 mm; (3) labium and labrum all pale, rather than partly black; (4) Hw base at most pale amber; (5) subcostal Ax and Pt usually pale rather than dark; (6) hook of hamule narrow and triangular, usually bent forward rather than outward.
