 Zygoballus sexpunctatus is similar in appearance to Zygoballus rufipes , with whom its range overlaps . The male can be distinguished from Z. rufipes by the large spot of white scales at the beginning of the <unk> slope ( which is lacking in Z. rufipes ) , and by the longitudinal division present on the bulb of the <unk> ( Z. rufipes has a transverse division ) . The female can best be distinguished by the form of the <unk> ( the external genital structure ) .
