New mimarachnids (Hemiptera, Fulgoromorpha, Fulgoroidea) in mid-Cretaceous Burmese amber

Abstract

A new genus and species, Multistria orthotropagen. et sp. nov., and a new species, Dachibangus huisp. nov., of Mimarachnidae are described from the mid-Cretaceous Burmese amber. These new taxa display unique wing color patterns and extend the Mesozoic diversity of Mimarachnidae. The evolution of wing venation, phylogenetic placement of Mimarachnidae, and anti-predation defenses of this family in Burmese amber forest are briefly discussed.

Morphological features of the Upper Cretaceous planthopper Mimaeurypterus burmiticus suggest specialization for cryptic camouflage on tree bark

“…Representatives of Mimarachnidae commonly show mottled color patterns or dark and light bands, these were interpreted as cryptic and disruptive coloration to camouflage the insects (Zhang et al, 2021). This adaptation is particularly useful as fulgoromorphans are phytophagous insects feeding on plant fluids, as such they have to stay in place for long periods of times to obtain adequate nutrition exposing them to potential predators (Stevens & Merilaita, 2009).…”
