Jurasaidae is a family of elateroid beetles known from around a half-dozen species in two genera found the Brazilian Atlantic rainforest including drier transitional areas bordering the Caatinga. All known species have neotenic larva-like females and normal males, similar to some other elateroids. They occur in the soil horizon immediately under leaf litter, with the larvae likely being fungivorous, consuming the fluids of fungal hyphae.[1][2][3][4]
