A new genus and species of parasitoid wasp is described from Burmese amber: Prototeleia kleiogen. nov., sp. nov. (Platygastroidea, Platygastridae). Prototeleia kleio exhibits multiple characters that we consider to be plesiomorphic for Platygastridae. These characters are analyzed and discussed in the context of extant and fossil taxa.

The Relationship

A new genus and species of the lacewing family Psychopsidae, Electropsychops handlirschi gen. et sp. nov., is described based on a well preserved male specimen from the mid-Cretaceous amber of Myanmar. The new genus possesses a number of diagnostic characters of Psychopsidae, i.e., the lack of a forewing median nygma, the presence of a vena triplica, and the straight and barely forked RA. However, it also exhibits some remarkable characters that are present in Osmylopsychopidae, such as the distally narrowed forewing costal space and the sigmoid MA stem in the hind wing. The relationship between Psychopsidae and Osmylopsychopidae is briefly discussed.

A new genus and species of scale insect (Hemiptera: Coccomorpha) is described from a female specimen in mid-Cretaceous Burmese (Myanmar) amber. Fossil female scales are rare and the present species, described as Paleolepidotus macrocolus gen. et sp. n., has such an unusual assortment of morphological features that it could not be assigned to any particular extant or extinct family. The small, ferruginous specimen exhibits a series of long wax pencils that extend around the body, including the head. The antennae and legs are quite long compared to other extant and extinct scale fossils. Of special interest are the protruding eyes, and a conical-triangular rostrum arising from between the forelegs; the claws with bifid apices are also unique. The ovisac contains immature stages.

Abstract Burmese amber is well known for preserving unique extinct lineages of insects. Here, we describe a new fossil beetle in its larval stage from Burmese amber. Bayesian and parsimony phylogenetic analysis of 50 morphological characters support this fossil as being sister to both the tribes Dineutini and Orectochilini, representing an extinct stem lineage in Gyrininae. It is described here as a new genus and species of whirligig beetle, Chimerogyrus gigagalea gen. & sp. nov., a taxon that preserves remarkable intermediate features between the whirligig beetle tribe Gyrinini and the crown Orectochilini and Dineutini. This new taxon preserves key features for studying the evolution of characters within the larval stage of the Gyrinidae and highlights the importance of Burmese amber for preserving both stem and crown lineages present during the mid-Cretaceous, before the end-Cretaceous mass extinction event.

A new genus and species of the extinct family Weitschatidae, Criniverticillus longicumulus gen. et sp. nov. (Hemiptera: Coccomorpha), is described and illustrated from mid-Cretaceous Burmese amber. The new species is based on a fossil specimen with complete body, wings and antennae. The family diagnosis is updated to include similarities between Criniverticillus, Pseudoweitschatus and Weitschatus. An identification key to species of Weitschatidae is provided.

A new fossil stonefly genus and species of the family Perlidae, Pinguisoperla yangzhouensis gen. et sp. nov., is proposed as the second known genus from mid-Cretaceous Burmese amber. The new genus is characterized by its dark coloration and the basally enlarged and curved cerci. Morphological characters of the new genus and species are described, illustrated, and compared with related taxa.

The lacewing family Nemopteridae Burmeister, 1839 is very poorly represented in the fossil record with three Early Cretaceous genera of uncertain affinities from the Brazilian Crato Formation, one ‘mid’-Cretaceous representative of the stem group of the Crocinae Navás, 1910 in the Burmese amber, and two Cenozoic nemopterine genera Marquettia Navás, 1913 (late Eocene-early Oligocene) and Paleonemia Claisse et al., 2019 (middle Oligocene). Also two undetermined Nemopterinae are recorded from the late Eocene and the Oligocene (Lu et al., 2019a: Table 1; Claisse et al., 2019).

And Function

Abstract Predation is a major driving force for the evolution of functional forms. Avoidance of visual predators has resulted in different kinds of anti-predator defences, such as: camouflage, crypsis, disruptive coloration, and masquerade or mimesis. Camouflage is one of the forms involving shape, colouration, structure and behaviour when the visual pattern and orientation of an animal can determine whether it lives or dies. Inferring the behaviour and function of an ancient organism from its fossilised remains is a difficult task, but in many cases it closely resembles that of its descendants on uniformitarian grounds. Here we report and discuss examples of morphological and behavioural traits involving camouflage named recently as a flatoidinisation syndrome, shown by the inclusion of a planthopper in mid-Cretaceous Burmese amber. We found a new genus and species of an extinct Cretaceous planthopper family Mimarachnidae showing peculiar complex morphological adaptations to camouflage it on tree bark. Due to convergence, it resembles an unrelated tropiduchid planthopper from Eocene Baltic amber and also a modern representatives of the planthopper family Flatidae. Flattening of the body, the horizontal position of the tegmina at repose, tegmina with an undulating margin and elevated, wavy longitudinal veins, together with colouration and more sedentary behavioral traits enable these different insects to avoid predators. Our discovery reveals flatoidinisation syndrome in mid-Cretaceous Burmese amber which may provide insights into the processes of natural selection and evolution in this ancient forest.

Dryinidae (Hymenoptera: Chrysidoidea) are parasitoids, and often also predators, of leafhoppers, planthoppers and treehoppers (Hemiptera: Auchenorrhyncha) (Guglielmino et al., 2013; Olmi et al., 2020b). Fossils of Dryinidae are known both as inclusions in amber and as compression fossils (Perkovsky et al., 2019; Olmi et al., 2010, 2020b; Martynova et al., 2020). Among the amber deposits, those situated in Myanmar are the richest. Mid-Cretaceous Burmese amber from Kachin State is known in fact to include Dryinidae belonging to the following subfamilies and genera: Anteoninae: Burmanteon Engel, 2003 (one species); Burmadryininae: Burmadryinus Olmi, Xu & Guglielmino, 2014 (one species); Dryininae: Dryinus Latreille, 1804 (12 species) (Martynova et al., 2020); Hybristodryinus Engel, 2005 (17 species) (Perkovsky et al., 2019; Tribull et al., 2020; Olmi et al., 2021; Wang et al., 2021); Pseudodryinus Olmi, 1991 (one species); Palaeoanteoninae: Palaeoanteon Olmi, 2000 (one species) (Perkovsky et al., 2020a); Raptodryininae: Raptodryinus Olmi, Perkovsky, Martynova, Contarini, Bückle, Guglielmino, 2020 (one species).
