hirsuta are long, smooth and strongly but evenly curved (Figs 39, 40, clw; 41), the puvilli are connected to tarsomere 5 basolaterally and consist of narrow, acutely-pointed blades with an arrangement of branched, regular Velcro-like hooks (Figs 39, 40, pulv; 41), the empodium is style-like, acutely-pointed and clothed in short spines (Figs 39, 40, emp; 41), and tarsomere 5 is furnished with an very long, downcurved dorsal pre-apical seta.
