Pinheyschna subpupillata (McLachlan, 1896)
Stream Hawker

Synonyms:

• scientific: Aeshna subpupillata

Type locality: Cape Province, South Africa

Diagnosis

Male is similar to P. rileyi by (a) stem of black mark on frons round and surrounded by pale area like bull’s-eye; (b) Pt 3.5-4 mm, over 8% of Hw length; (c) membranule dark, basal half distinctly white; (d) anal triangle of 3 cells, only rarely 2; (e) genital lobe elongate, apex rounded or truncate. However, differs by (1) ranging from Zimbabwe to South Africa; (2) relatively smaller size, Hw 39-41 mm; (3) space between lateral stripes with pale marking near Fw base; (4) costa pale yellow rather than brown, and many cross-veins near base yellow, including those in triangles, contrasting with dark surrounding veins (rather than all venation being uniformly dark); (5) genital lobe distinctly curved, rather than rather straight.
