Palpopleura portia (Drury, 1773)
Portia Widow

Synonyms:

  • scientific: P. lucia (Drury, 1773) f. "portia"
  • vernacular: Shadow-bridge W.; Silver-winged W.

Type locality: Sierra Leone, no locality data available.

Diagnosis

Male is similar to P. lucia by (a) frons and vertex blue-black metallic with maturity, contrasting weakly with dark face; (b) sides of thorax dark, often with pale stripes; (c) basal black on wings solid, extends beyond node and often even distal to Pt. However, differs by (1) relatively smaller size, Hw 17-24 mm; (2) mesepisterna usually pruinose with maturity; (3) posterior border of black field in all wings deeply excavated near node.
