THE GENUS CLASTOPTERA (CERCOPIDAE)
Published online by Cambridge University Press: 31 May 2012
Extract
The members of this genus are all small and globose and are easily separated from other Cercopidae, but here the easy part abruptly ends. The varieties are widely variable in size, form and color, ranging in most species from large pale forms through spotted, striped and variously ornamented ones on down through coppery and bronzy shades to small black forms at the other extreme. The representatives of this group are distributed through North and South America where some 68 or 70 different forms have been named. All of the earlier ones and most of those of later date have been founded on size and color markings alone, which vary with the sex, the food plant, the environment and in some cases at least with the season. Under the circumstances it is manifestly impossible to determine the number of species involved or to work out a stable nomenclature until extended collection and careful life history has been done in the areas involved.
