New species of Hybristodryinus Engel (Hymenoptera, Dryinidae) from mid-Cretaceous amber of northern Myanmar, with notes on their possible hosts

Abstract

Two new species of Hybristodryinus Engel, 2005, are described from mid-Cretaceous amber of northern Myanmar: H. castaneussp. nov. (based on one male) and H. zaifuisp. nov. (based on one female). Keys to the females and males of Hybristodryinus species are modified to include the two new taxa. A syninclusion, a nymph of Cixitettiginae (Perforissidae), present in the same amber piece containing H. zaifui, is studied. This syninclusion, together with the presence of Antennal Dorsal Organs (ADOs) in Hybristodryinus, suggests that Perforissidae are possible hosts of Hybristodryinus.

A new species of Bocchus from upper Eocene Rovno amber (Hymenoptera, Dryinidae)

“…Dryinidae (Hymenoptera, Chrysidoidea) are parasitoids of Auchenorrhyncha (Hemiptera) (Olmi 1984;Guglielmino et al 2013). This family is present in all continents, except for Antarctica, and comprises about 1900 species (Olmi et al 2021a).…”

Paradoxical derbid-like planthopper (Homoptera: Fulgoroidea) from Cretaceous Burmese amber

“…Mid-Cretaceous Burmese amber, formed about 100 Myr ago on an island in the tropical ocean between Gondwana and Laurasia [Westerweel et al, 2019], contains a rich insect fauna [Ross, 2021]. Among speciose Burmite Fulgoroidea, there are four endemic families -Dorytocidae, Yetkhatidae, Jubisentidae, Katlasidae [Emeljanov, Shcherbakov, 2018;Song et al, 2019Song et al, , 2021Luo et al, 2020;Shcherbakov, 2020], three widespread Cretaceous families -Perforissidae, Mimarachnidae, Neazoniidae [Shcherbakov, 2007;Fu, Huang, 2021;Olmi et al, 2021], three extant families -Cixiidae, Achilidae, Derbidae [Shcherbakov, 2000;Szwedo, 2004;Emeljanov, Shcherbakov, 2020], and a Pronotum long, saddle-shaped, with broad lateral lobes, without high lateral, posterior, or inferior carinae. Mesonotum ecarinate, without scutellar grooves.…”
