Second tarsomere of fore leg of female 1.0–1.3X longer than wide, with fleshy pad extending over most of ventral surface (Fig. 47); basitarsus of male fore leg 3.0–4.0X longer than wide (Fig. 50). Fore wing areolet with 2m-cu arising from distal half, often near apex (Figs 38–39)........................................................... W. ruficeps Brullé
