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).

A new genus and species of damselfly, Burmagrion marjanmatoki, gen. et sp. nov., is described from Early Cretaceous Burmese amber. It is attributed to the basal stem group of Coenagrionoidea. The inclusion of five wings from the same species suggests that the amber piece contains the remains of a mating pair of damselflies.

Characteristic Features

An unusual and well-preserved fossil staphylinid is described and figured from a single specimen in Upper Cretaceous Burmese amber. Gollandiaplanatagen. et sp. n. is tentatively placed in the extant oxyteline tribe Coprophilini, although it lacks a few characteristic features of present-day members of the group, likely indicating it to be either a stem group of the tribe or prove to be distinct pending future discoveries. The discovery of this genus suggests that early oxytelines were more morphologically diverse during the Cretaceous and their evolutionary history was more complicated than previously documented. Tribal placement as regards fossil oxyteline taxa is discussed.

History Of

Complex interspecies relationships are widespread among metazoans, but the evolutionary history of these lifestyles is poorly understood. We describe a fossil beetle in 99-million-year-old Burmese amber that we infer to have been a social impostor of the earliest-known ant colonies. Promyrmister kistneri gen. et sp. nov. belongs to the haeteriine clown beetles (Coleoptera: Histeridae), a major clade of ‘myrmecophiles’—specialized nest intruders with dramatic anatomical, chemical and behavioral adaptations for colony infiltration. Promyrmister reveals that myrmecophiles evolved close to the emergence of ant eusociality, in colonies of stem-group ants that predominate Burmese amber, or with cryptic crown-group ants that remain largely unknown at this time. The clown beetle-ant relationship has been maintained ever since by the beetles host-switching to numerous modern ant genera, ultimately diversifying into one of the largest radiations of symbiotic animals. We infer that obligate behavioral symbioses can evolve relatively rapidly, and be sustained over deep time.

Fossil Records

Die Fächerflügler (Strepsiptera) sind mit nur ca. 600 beschriebenen rezenten Arten eine kleine, parasitische Gruppe der holometabolen Insekten. Fossilfunde sind selten, aber in den letzten Jahren hat sich die Kenntnis der Stammgruppe der Strepsiptera durch die Entdeckung gut erhaltener Arten aus kreidezeitlichem burmesischem Bernstein und eozänem baltischen Bernstein stark vermehrt. Bis auf ganz wenige Ausnahmen, wie eine fossile Primärlarve aus burmesischem Bernstein und ein spätes weibliches Larvenstadium der †Mengeidae aus baltischem Bernstein, sind nur Männchen bekannt. Diese Bernsteinfossilien haben wesentlich zum Verständnis der Evolution der Strepsiptera im späten Mesozoikum und Känozoikum beigetragen. Die Stammgruppenvertreter der Fächerflügler werden vorgestellt und in einen evolutiven Kontext eingeordnet. The stem-group of the twisted-winged parasites (Insecta, Strepsiptera) Abstract: With only about 600 described extant species, the twisted-winged parasites (Strepsiptera) are a small, parasitic group of holometabolous insects. Fossil records of Strepsiptera are rare, but in the last years the knowledge of the stem group has greatly increased with the discovery of well-preserved species from Cretaceous Burmese amber and Eocene Baltic amber. With very few exceptions, such as a fossil primary larva from Burmese amber and a late female larval stage of the †Mengeidae from Baltic amber, only males are known. These amber fossils have greatly contributed to the understanding of the evolution of Strepsiptera in the late Mesozoic and Cenozoic. The stem group representatives of the twisted-winged parasites are described and placed in an evolutionary context.

Stem Group

ABSTRACTA small fossil insect with scales on the wings and body was identified as a representative of Aphiesmenoptera from Burmese amber. The species is introduced here as Tarachocelis microlepidopterella (†). The insect is described in detail, and photos and line drawings are provided for wing venation, head, mouthparts, scales, legs and abdomen. All characters shared with primitive Lepidoptera and Trichoptera are symplesiomorphies or groundplan traits of Amphiesmenoptera. In addition, the Burmese fossil has a number of remarkable autapomorphies, giving it an appearance that deviates clearly from known families of Lepidoptera and Trichoptera. The species, representing a family of its own, Tarachocelidae, is considered a separate and unique taxon in the stem-group of Amphiesmenoptera and is provisionally placed as Amphiesmenoptera incertae sedis.**NB: See Note Added in Proof (Section 4).

The male of Cretaconiopteryx grandis Liu & Lu, 2017, which is the only representative species of the extinct dustywing subfamily Cretaconiopteryginae, is described for the first time from the Upper Cretaceous Burmese amber. The male genitalia, well preserved in the examined specimen, show a number of plesiomorphic characters, which support the sister group relationship between Coniopterygidae and the rest of extant lacewing families.
