ETYMOLOGY: The specific name refers to the color pattern on the anterior legs.

MALE (PBI_OON 36759, figs. 555–599): Total length 1.64. Endites with oblique longitudinal ridge. Soft portions of abdominal dorsum with dark patches. Femora, patellae, and basal half of tibiae I, II darkened. Embolus wide, short, triangular, prolateral side of tip sharply bent (figs. 562– 567).
