Chrysso
''Chrysso'' is a spider genus that mostly occurs in the Americas and Asia. ''C. pulcherrima'' is pantropical, ''C. nordica'' occurs from Hungary to Mongolia, and in North America, and ''C. spiniventris'' has been intruced in Europe. The females are about 9 mm long, the hairs on the tip of the abdomen are blade-like. Many species are strikingly colored, but, as in most theridiids, the coloration is variable. ''C. compressa'' for example has a striking black sternum and abdomen with a black venter in Brazil, but a yellow venter in Peru. ''C. venusta'' has been observed to rapidly change its color when disturbed. ==References==
