256 Euura variator group

Closely related to the histrio and opacipleuris groups. Females have a rectangular or square-shaped valvula 3 in dorsal view, not clearly pointed and narrowing towards the tip as in the histrio and opacipleuris groups. Valvula 3 and lancets are very similar to the toeniata group, and some specimens of the variator group (particularly of E. variator ) may not be clearly distinguishable from E. obscuripes ( toeniata group) if the colouration is very similar. Penis valves are slightly different from the histrio and opacipleuris groups, but not always distinguishable from the vittata and toeniata groups. Three species are recognised.
