TL;DR: Three new genera of extinct Dictyopharidae, Lophopidae and Eurybrachyidae respectively are described and a representative of an unrecognised family, possibly related to Henriksenopterix Petrulevicius, 2005 is reported.
Abstract: Three new genera of extinct Dictyopharidae, Lophopidae and Eurybrachyidae respectively are described. Wedelphus gen. nov. with Wedelphus dichopteroides sp. nov. placed in Dictyopharidae, Baninus gen. nov. with Baninus thuringiorum sp. nov. of the family Lophopidae and Amalaberga gen. nov. with Amalaberga ostrogothiorum sp. nov. placed in Eurybrachidae (first fossil record of the family) are described, all from deposits of the Grube Messel Lagerstatte in Germany. A representative of an unrecognised family, possibly related to Henriksenopterix Petrulevicius, 2005 is reported. The oil shales of the Messel maar in Hessen are well known for their extremely rich fossil flora and fauna. They are of Lower Middle Eocene age (about 48 million years) and contain a highly diverse insect fauna.
TL;DR: The new genus of Eurybrachidae Chewobrachys n.
Abstract: The new genus of Eurybrachidae Chewobrachys n. g. (Hemiptera, Fulgoromorpha) is described for two species from Eastern Australia, Platybrachys sanguiflua (Walker, 1858) and Chewobrachys limbourgi n. sp. The new combination Chewobrachys sanguiflua (Walker, 1858) n. comb. is proposed and Platybrachys insignis Distant, 1892 is proposed as a junior synonym of C. sanguiflua. The male and female genitalia are illustrated and photos of habitus, distribution maps and biological data are provided with the description of the species. A key to the species of Chewobrachys is given. Lectotypes are designated for Eurybrachys sanguiflua Walker, 1858 and Platybrachys insignis Distant, 1892. The new genus is provisionally placed in the tribe Platybrachyini Schmidt, 1908.
