A new fossil species of the superfamily Tenebrionoidea, Coslonatus rasnitsyni gen. et sp. nov., is described and illustrated from the mid-Cretaceous Burmese amber. The new genus is tentatively placed in the extant subfamily Colydiinae (Zopheridae) based primarily on the 4-segmented tarsi, clubbed antennae, and all freely connected abdominal ventrites. Coslonatus is unique in Colydiinae in having dorsally located antennal insertions and markedly long antennae, suggesting a unique ecological niche of the new species.

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.

Abstract. Rhopalosomatidae, currently considered the sister group of the Vespidae, are an enigmatic family of aculeate wasps that originated in the Late Jurassic or Early Cretaceous. Despite their considerable age, very few fossils of the family have been reported – all of them in amber (Miocene Dominican, Miocene Mexican, and mid-Cretaceous Burmese ambers). Here we report a new mid-Cretaceous rhopalosomatid wasp, Cretolixon alatum Lohrmann, gen. et sp. nov., from Burmese (Kachin) amber. This new genus has a unique mixture of characters, some of which are only known from the recent brachypterous genus Olixon and others of which are known only from the recent macropterous genera. Thus, Cretolixon Lohrmann, gen. nov. not only provides further evidence for the monophyly of the family but also contributes evidence for the monophyly of the Rhopalosomatinae. Key characters of the family are discussed, and an updated checklist of the world genera and fossil species and occurrences of Rhopalosomatidae is provided. Additionally, a chemical analysis was performed for three of the newly reported fossils as well as for the amber piece containing the rhopalosomatid larva described by Lohrmann and Engel (2017) to ascertain their amber vs. copal nature and their affinities with each other and previously described Burmese amber.

A new fossil species of the family Compsocidae, namely Burmacompsocus coniugans sp. nov. is described from Late Cretaceous Burmese amber. Diagnostic characters separating the new species from the previously known representatives of the genus are discussed. Details of mouthparts and genitalia are described for the genus for the first time. The discovery of the new species supports the hypothesis of higher Compsocidae diversity existing in the past compared with the present.

Small Family

Hybosoridae is a relatively small family of Scarabaeoidea, including five extant and one fossil subfamily (Ocampo & Ballerio 2006, Nikolajev 2007). Until now, 20 fossil species were known from five subfamilies: Anaidinae, Ceratocanthinae, Hybosorinae, Liparochrinae, and Mimaphodiinae (Ocampo & Ballerio 2006, Krell 2007, Nikolajev 2008, Nikolajev et al. 2010, Nikolajev 2010a, Nikolajev 2010b, Kirejtshuk et al. 2011). In this paper we describe Pulcherhybosorus tridentatus Yan, Bai, & Ren new genus and new species, from a nearly complete and well-preserved fossil. This fossil represents the first record of Hybosoridae from the Early Cretaceous Yixian Formation of Liutiaogou, Inner Mongolia in China. This significant finding tentatively confirms the presence of Hybosoridae during the Mesozoic in what is now China.

A new genus and two new amber fossil species of Leiodidae are described: Catops perkovskyi sp. n. (CholevinaeCholevini) and Tafforeus cainosternus gen. n., sp. n. (Leiodinae Pseudoliodini); using virtual dissection by propagationphase contrast synchrotron X-ray microtomography, which allows for visualization of the genital structures in a non-invasive way. The external and internal morphology of the new species is compared to that of the extant related species.Putative evolutionary relationship between Tafforeus and the genus Cainosternum Notman, 1921, and their placement in the tribe Pseudoliodini are discussed.

The taxonomy of the predominantly Australian fossil dipnoan genus, Neoceratodus, is revised and the Recent Australian lungfish, Neoceratodus forsteri, and two fossil species, Neoceratodus eyrensis and Neoceratodus nargun, are redefined. Two new species of the related Tertiary genus, Mioceratodus, are described on the basis of tooth plates from central and northern localities in Australia. These are Mioceratodus diaphorus and Mioceratodus poastrus. A new genus, Archaeoceratodus, is erected to include three rare Tertiary species and one Mesozoic species. The Tertiary members of this genus are the type species, Archaeoceratodus djelleh, described originally as Neoceratodus djelleh, and two new species, Archaeoceratodus rowleyi and Archaeoceratodus theganus. The Mesozoic species is Archaeoceratodus avus from Triassic and Cretaceous deposits in southeastern Australia, described originally as Ceratodus avus. All three genera belong in the family Neoceratodontidae.

The Family

A new genus belonging to the cucujoid family Helotidae, Trihelota gen. nov., is described from mid-Cretaceous (ca.99 million years old) amber from Kachin State, northern Myanmar, containing a single species T. fulvata sp. nov. The minute fossil was documented using fluorescence microscopy and X-ray microtomography to reveal fine morphological details. Trihelota is characterised by its transverse head, antennal club about 1.5 times longer than wide, pronotum almost parallel-sided, and elytra not costate. Notably, each elytron possesses three coloured spots, a character unique within Helotidae. The new genus considerably expands the known morphological disparity of Cretaceous helotids. A keyto extinct and extant genera of the family Helotidae is provided along with a checklist of fossil species.

Dated Phylogeny

Among the eleven modern subfamilies of non-biting midges (Diptera: Chironomidae), Buchonomyiinae are the most primitive and considered to be the sister group to the rest of the chironomids. The subfamily is monotypic with a single genus Buchonomyia, including three Recent species from Europe, South-East Asia and Central America, and a single fossil species, B. succinea Seredszus and Wichard, 2002, from Baltic amber. The elusive nature of the larvae and pupae, who develop as parasites or are commensal of caddisfly larvae, means that records of recent Buchonomyiinae extremely rare. From the latest dated phylogeny of the Chironomidae, the Buchonomyiinae branched from the rest of the Chironomidae in the Early to Middle Jurassic. Here we present the oldest record of the subfamily Buchonomyiinae, from Late Cretaceous Burmese amber. The record is represented by a new genus Furcobuchonomyia, with a single species F. saetheri. Bayesian analysis firmly places the new genus as the sister group to the rest of the Buchonomyiinae. Thus the discovery of this genus is sheding new light on the origin of the most basal group of the Chironomidae. A species level key to the subfamily is included.
