Females can be recognised by the distinct colour patterns on body ( Figs 20, 21 View FIGURES 10–24 ); epigyne with atrium well defined, rim oval to U-shaped ( Fig. 59 View FIGURES 57–68 ); intromittent orifices open antero-laterally, intromittent canals very long and complex ( Fig. 60 View FIGURES 57–68 ). In male palp, the bulb is large and round; RTA with slender tip extending dorsolaterally ( Figs 57, 58 View FIGURES 57–68 ).
