Paropsis has random or meandering puncturation, verrucae (warts; bumps) on elytra and crenulate margin of pronotum.
Paropsisterna have puncturation in ten (or 9.5) straight lines, smooth margin of elytra and smooth, no bumps on elytra.
There are very few exceptions to these guidelines, technically the distinction between these two genera is a ridge on the prosternal (ventral) process for Paropsis, lacking in Paropsisterna.
