Only a few weevils have been described from Burmese amber, and although most have been misclassified, they show unusual and specialised characters unknown in extant weevils. In this paper, we present the results of a study of a much larger and more diverse selection of Burmese amber weevils. We prepared all amber blocks to maximise visibility of structures and examined these with high-magnification light microscopy as well as CT scanning (selected specimens). We redescribe most previously described taxa and describe 52 new species in 26 new genera, accompanied by photographs. We compare critical characters of these weevils with those of extant taxa and outline the effects of distortion on their preservation and interpretation. We conclude that only two weevil families are thus far represented in Burmese amber, Nemonychidae and a newly recognised family, Mesophyletidae, which appears closely related to Attelabidae but cannot be accommodated in this family. The geniculate antennae and long rostrum with exodont mandibles of most Mesophyletidae indicate that they were highly specialised phytophages of early angiosperms preserved in the amber, likely ovipositing in flowers or seeds. This weevil fauna appears to represent an extinct mid-Cretaceous ecosystem and fills a critical gap in the fossil record of weevils.

A new family, Electrocambalidae fam. nov. of the suborder Cambalidea is described from Cretaceous Burmese amber based on two new genera, Electrocambala gen. nov. and Kachincambala gen. nov. with four new species, Electrocambala ornata gen. et sp. nov., E. cretacea gen. et sp. nov., Kachincambala muelleri gen. et sp. nov. and K. distorta gen. et sp. nov. The specimens are described combining classical light microscopy with drawings and photography, and modern micro-computed tomography (μCT). Morphological characters otherwise obscured are examined and visualized by creating volume renderings and 3D-segmentations from μCT data. Electrocambalidae fam. nov. is characterized by the following character combination: (1) a forward shift of leg pair 3, resulting in an apparently legless 3rd body ring, (2) presence of metazonital setae, and (3) extensive pilosity on the head. Although some of these characters are shared with other Juliformia they are unique in this combination. The described fossils are the oldest and first Mesozoic Spirostreptida and Cambalidea known and ca 70 million years older than previous records of the group.

Three new genera and five new species of Darwin wasps (Ichneumonidae) are described from the mid-Cretaceous Burmese (Kachin) amber: Heteropimpla pulverulenta sp. nov., Rasnichneumon alexandri gen. et sp. nov., R. gracilis sp. nov., Heteroichneumon rasnitsyni gen. et sp. nov., and Rogichneumon braconidicus gen. et sp. nov. The genus Heteropimpla is transferred to Novichneumoninae. The subfamily Novichneumoninae, comprising 6 genera with 8 species, is endemic to Burmese amber, and no other subfamilies of Ichneumonidae are known in the Burmese assemblage. Ichneumonids are extremely rare in Burmese amber, as well as in other Cretaceous amber faunas. However, nine known specimens represent nine different species (one is not formally described due to poor preservation), indicating a serious paleontological record gap for Burmese Darwin wasps.

Currently, the Onisicdea (terrestrial isopods) is a massive Crustacea suborder of more than 3 700 species, but our knowledge of their paleodiversity is poor. In this paper, we present ten fossils of Crinocheta, the largest clade within the Onisicdea, discovered in Early Miocene (23 Ma) amber of Chiapas. We described three new genera and six new species including Palaeolibrinus spinicornis gen. nov. sp. nov., Armadilloniscus miocaenicus sp. nov., Archeostenoniscus robustus gen. nov. sp. nov., Archeostenoniscus mexicanus sp. nov., Palaeospherarmadillo mazanticus gen. nov. sp. nov., and Palaeospherarmadillo rotundus sp. nov. This study represents the first fossil record of the family Detonidae, Olibrinidae, and “Stenoniscidae”. From a paleoenvironmental reconstruction perspective, the oniscidean fauna presented here supports a particularly wet paleoenvironment, under brackish water influence, similar to an estuary.

Fossil Records

AbstractThorny lacewings (Rhachiberothidae) are currently distributed only within Africa, whereas they are prevalent in the fossil record of various Cretaceous ambers across the Northern Hemisphere, with a handful of the fossil records from some Eocene European ambers. Four rhachiberothid species in four extinct genera are known from the mid-Cretaceous amber of northern Myanmar. Here, we report further examples of the remarkable palaeodiversity of this group from the same amber deposit, adding the four new fossil genera and seven new species: Acanthoberotha cuspis gen. et sp. nov., Astioberotha falcipes gen. et sp. nov., Stygioberotha siculifera gen. et sp. nov., Uranoberotha chariessa gen. et sp. nov., Creagroparaberotha cuneata sp. nov., Micromantispa galeata sp. nov. and M. spicata sp. nov. Based on a series of well-preserved specimens, we discuss the fine details of the raptorial forelegs and genital segments, which may be important for elucidating the phylogenetic relationships among genera. Our findings reveal an unexpectedly diverse assemblage of thorny lacewings in the Cretaceous System, highlighting the morphologically diverse rhachiberothids in Burmese amber. The discovery of seven additional rhachiberothid species in Myanmar amber suggests the potential for much higher diversity and abundance of the Cretaceous rhachiberothids than previously documented. Furthermore, morphological variation in the raptorial forelegs was found to be extremely diverse among the Burmese amber paraberothines, especially in terms of the size, number and shape of spines (or spine-like setae) on the inner edges of protibia, and the morphological structure of the probasitarsus.

New Occurrences

With the exception of polycopids, Mesozoic myodocopid ostracods are regarded as uncommon in the fossil record. They are known from a few localities in the Tethys, and most of them are considered to be pelagic forms. However, a relatively rich and taxonomically diverse material is derived from Hungarian sections; these represent various formations deposited during the Triassic to Cretaceous.The aim of this study is to summarize the current knowledge of Mesozoic myodocopids and to provide new information concerning their classification and phylogenetic relations. This includes new occurrences of Triassic entomozoid Schallreuterizoe groosae Kozur, 2004, cylindroleberidid Triadocypris sp., cypridinid Palaeocypridina tulceaensis Sebe, 2013, Jurassic thaumatocyprid Pokornyopsis cf. bettenstaedti (Bartenstein, 1949) and P. feifeli (Triebel, 1941). The revision of the holotype of gigantic Triassic Triadogigantocypris balatonica Monostori, 1991 give new results concerning the valve structure and taxonomic position of the genus. Two new genera (Neorichterina n. gen. and Hungaroleberis n. gen.) and four new species (Neorichterina striata n. sp., Pokornyopsis csurgokutensis n. sp., Hungaroleberis retiferus n. sp. and Palaeocypridina goeroegae n. sp.) of the subclass Myodocopa are described. Moreover, most of the Albian to Cenomanian representatives of “Conchoecia” are newly classified as Entomozoidae (Neorichterina n. gen.), which allows to extend the range of the family up to the Cretaceous. A summary of the relevant assemblages present in Hungary will help to complement the existing, previously published literature on myodocopids, and also clarify details about the phylogenetic model of the group.

A phylogenetic analysis of the Cirripedia family Oxynaspididae yields four monophyletic clades. These are designated as four genera, Oxynaspis Darwin, 1852, Archoxynaspis gen. nov., Pycnaspis gen. nov. and Minyaspis gen. nov. Five new species from Astrolabe Reef in Fiji (Oxynaspis perekrestenkoi sp. nov., O. joankovanae sp. nov., Minyaspis amylaneae sp. nov., M. opreskoi sp. nov. and M. welchi sp. nov.) and one from Palau (Oxynaspis joandianae sp. nov.) are described. A morphological character dataset and resulting phylogeny supporting the new generic divisions is presented. All but two of the 24 species previously known and all six of the newly described species are intimately associated with antipatharians. Pycnaspis connectens was described by Broch (1931) as “fixed to a silicious sponge.” A list of species’ ranges and their known hosts is presented. The earliest known possible antipatharian in the fossil record is Miocene, much later than the Eocene appearance of Archoxynaspis eocenica (Withers, 1935). Therefore, the symbiosis of oxynaspidids with antipatharians may have evolved only since the Miocene. However, given the dubious fossil record of antipatharians (known only from a single specimen of uncertain affinity from Miocene Italy) the time of the first antipatharian/oxynaspidid symbiosis is uncertain.

Bruchomyiinae from Burmese, Baltic, and Caribbean amber are revised. Five new species from Baltic, one from Caribbean and three from Burmese amber are described. Based on recently discovered specimens, additional details and corrections for previously described species are provided. Six species from Baltic amber were combined in Hoffeinsodes gen. nov. (Hoffeinsodes obtusa sp. nov., H. bifida sp. nov., H. cubicula sp. nov., H. longicauda sp. nov., H. reducta sp. nov. and H. hoffeinsi (Wagner 2006) comb. nov.), based on the fusion of gonocoxites and hypandrium, and a laterally expanded epandrium with posterolateral lobes. Genus Palaeosycorax Meunier, 1905 is re-validated, with Palaeosycorax inexpetatus (Wagner, 2012) comb. nov. included. Caribbean amber species Boreofairchildia dominicana sp. nov. and B. hennigianus (Schlüter, 1978) comb. nov. are congeneric with extant genus Boreofairchildia Wagner & Stuckenberg, 2016. Three new and two described species from Burmese amber are combined in Palaeoglaesum gen. nov. (Palaeoglaesum quadrispiculatum (Stebner et al., 2015) comb. nov., P. velteni (Wagner, 2012) comb. nov., P. muelleri sp. nov., P. bisulcum sp. nov., P. notandum sp. nov.), based on their small size relative to other Bruchomyiinae, and presence of a Y-shaped aedeagal sclerite. Keys to males of species in particular ambers are provided.
