Forelegs: Taeniaptera trivittata - first tarsomere dark, remaining tarsomeres light (apical tarsomere dark in the rare southern Taeniaptera lasciva); Rainieria antennaepes - first tarsomere white, sometimes with apical tarsomere dark; Calobatina geometra - first tarsomere white, last 2-3 tarsomeres dark
