Abstract

Cretaceous resins have preserved a remarkable diversity of sternorrhynchans. Burmese amber, formed in the mid-Cretaceous tropics, contains more numerous and diverse Psyllomorpha than all other fossil localities of the period together. The genus Dingla Szwedo et Drohojowska, 2020, previously placed into a separate family and infraorder, turned out to be similar in all essential characters to Mirala Burckhardt et Poinar, 2019 and Burmala Liu et al., 2021; therefore we synonymize Dinglidae Szwedo et Drohojowska, 2020 with Miralinae Shcherbakov, 2020 and raise the last subfamily to the full family status based on several unique apomorphies. A sister-group relationship between Dinglomorpha and Aleyrodomorpha was based on incorrect interpretation of characters. Pictala scorpioides gen. et sp. nov. from Burmese amber differs from other miralid genera by spotted forewings without pterostigma and the structure of terminalia in both sexes. In Miralidae, we discovered a long annulated labium and compound wax pores on the ventral side of the abdomen—for the first time among Hemiptera. The compound wax pores may have helped prevent miralids from sticking to the honeydew excreted. The long, flexible second labial segment, reinforced by sclerotized rings, probably allowed the protrusible length of the stylet bundle to be increased by arching the labium, as in mosquitoes.

期刊介绍： Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings. Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale. Research Areas include: • Regional geology • Stratigraphy and palaeontology • Palaeobiology • Palaeobiogeography • Palaeoceanography • Palaeoclimatology • Evolutionary Palaeoecology • Geochronology • Global events.
