A new species of Meropeidae (earwigfly) is described and figured based on an exceptionally well-preserved individual in mid-Cretaceous amber from Myanmar. Burmomerope clara Zhao and Wang, sp. nov. is distinguished from the type species B. eureka Grimaldi and Engel, 2013 by presence of broader wings with six longitudinal veins in radial sector and seven in medial field, CuA with two terminal branches, and long setae on the anterior margin of the wing. A detailed comparison of the forewings venation in all fossil and extant species is given. The new find is the third fossil species of Meropeidae and also the first fossil female to be described. The female genital structure of B. clara sp. nov. is remarkably similar to that of extant species, revealing 100 million years of morphological conservatism, and thus highlighting the antiquity of the group. 相似文献

One new osmylid genus and species, Burmaleon magnificus, and one new nymphid genus and species Rafaelnymphes cratoensis are described, respectively based on inclusions in the Cretaceous Burmese amber and on a compression fossil from the Crato Formation in Brazil. The nymphid Araripenymphes seldeni, from the Crato Formation, is redescribed on the basis of a new specimen, showing possible sexual dimorphism in wing coloration, a feature extremely rare among the Neuroptera. In a recently published phylogenetic analysis of the family, the attribution to the fossil taxa (versus rejection) of the larval characters proper to the modern nymphids, has a crucial impact on the resolution of the phylogeny. The compression fossils currently attributed to the Nymphidae should be revised because their wing venation alone is not really sufficient for an accurate family attribution to Nymphidae rather than to another family of Neuroptera (viz. Osmylidae). 相似文献

The lacewing family Babinskaiidae (Neuroptera: Myrmeleontoidea) is first reported in mid-Cretaceous amber from Myanmar. Two new genera and three new species are herein described, namely Babinskaia martinsnetoi sp. nov., Burmobabinskaia tenuis gen. et sp. nov., and Electrobabinskaia burmana gen. et sp. nov. The male and female genitalia of Babinskaiidae are described for the first time, and the genital morphology is compared with that of some related families in Myrmeleontoidea, e.g., Nymphidae and Nemopteridae. A brief discussion on the phylogenetic status of Babinskaiidae is given. 相似文献

Partially complete right antler from the Pinjor Formation (Pleistocene) of the Upper Siwalik Subgroup is identified, described and its phylogenetic relationship is discussed. The fossil antler is compared with other known fossil records of family Cervidae as well as with the extant species, on the basis of which it can be attributed to Axis punjabiensis. This species has not been reported previously from this fossil site. 相似文献

Although recent molecular phylogenetic analyses suggest a great antiquity, going into the Jurassic, for the small modern fly family Hilarimorphidae, no fossil was attributed to this group. The first fossil hilarimorphid Cretahilarimorpha lebanensis gen. et sp. nov., is described, based on a specimen from the Lower Cretaceous Lebanese amber. Its external morphology is analysed and compared with that of Hilarimorpha, unique modern hilarimorphid genus. The differences concern the wing venation, antenna and especially mouthparts. Cretahilarimorpha has very elongate mouthparts, adapted for nectar feeding or (less probably) for predation on other insects. Several other Lower Cretaceous lineages have developed similar elongate mouthparts, viz. nemestrinid and xylomyiid flies, and the Mecoptera: Aneuretopsychina, probably adapted to still unknown deep nectar-producing flowers. A checklist of species belonging to the Hilamorphidae is given. 相似文献

Three new genera and two new species, namely Burmodipteromantispa jiaxiaoae gen. et sp. nov., Mantispidipterella longissima gen. et sp. nov., and Jersimantispa gen. nov., respectively from the Cretaceous amber of Myanmar and New Jersey, are herein described in the lacewing family Dipteromantispidae, which is an enigmatic group by the mantispid-like appearance combined with strongly reduced, haltere-like hind wings. The male genitalia of Dipteromantispidae is described for the first time and provides new insight for understanding the familial phylogenetic position. A key to the dipteromantispid genera is also given. 相似文献

The Eomeropidae is a species-poor family with only 11 known fossil species from the Early Jurassic to Palaeogene. A new species of fossil eomeropid, Tsuchingothauma gongi sp. nov., is described based on a well-preserved wing from the Middle Jurassic Daohugou deposits of Inner Mongolia, China. Our new species is distinguished from the type species T. shihi mainly in having very numerous crossveins and cells; more longitudinal veins: 13 and 11 terminal branches in radial sector and medial field, CuA with 3 terminal branches and A with 7 terminal branches. 相似文献

The first definitive fossil of the peculiar monotypic rove beetle subfamily Megalopsidiinae is described as a new species Megalopinus extinctus sp. n. It represents a stem lineage valuable for the study of the early diversification of Staphylinidae, where sister group relationships of Megalopsidiinae currently remain a big controversy. This discovery corroborates the Mesozoic origin of this subfamily implied by its presumably basal phylogenetic position within Staphylinidae and hitherto available fossil record for the family. Well preserved peculiar mouthparts of M. extinctus specialized similarly with recent Megalopinus suggest the same mode of feeding in Megalopsidiinae for nearly a hundred million years. 相似文献

The first definitive Burmese amber fossil of the family Gasteruptiidae s.str. (Evanioidea) is described and figured from a male entombed in amber from the Hukawng Valley, Myanmar. The Cenomanian-aged fossil is plesiomorphic in many respects when compared to the modern subfamilies Hyptiogastrinae and Gasteruptiinae. The genus Hypselogastrion Engel, gen. nov. (type species: Hypselogastrion simplex Engel and Wang, sp. nov.), is segregated into the extinct subfamily Hypselogastriinae Engel, subfam. nov., owing the more enriched wing venation, aulcid-like mesoscutal sculpturing, non-clavate metatibia, and absence of U-shaped notauli. The affinities of H. simplex among other living and fossil Aulaciformes are discussed. 相似文献

The Cretaceous new species and genus Albocryptophagus cantabricus gen. et sp. n. is described based on a fossil specimen from the El Soplao amber deposit (Spain). The new genus is similar to the extant genera Cryptophagus and Micrambe, but differs from them in the transverse pedicel, anterior angles of pronotum, pronotal margin unmodified, pronotal pits absent. Albocryptophagus gen. n. is undoubtedly the most ancient representative for the subfamily Cryptophaginae described up today. Because the saproxylic habits in recent species of the family, a similar behavior is inferred for this new fossil. It is a new example that agrees with the idea that fossil beetles from Mesozoic ambers are characterized by a saproxylic lifestyle. 相似文献

A new species, Eoptychoptera cantabrica sp. nov. is described from the Albian El Soplao amber-bearing deposits based on a single male with an elongated proboscis, unknown among extant members of Ptychopteridae. It represents the youngest record of the species-diverse genus Eoptychoptera. A pupa of Eoptychoptera sp. with a long respiratory horn, typical of extant ptychopterids, is described from Las Hoyas limestones, where adult fossil ptychopterids have yet to be discovered. A key to species of Eoptychoptera, based on wing venation, and a distribution map of Cretaceous Ptychopteridae are provided. The climatic preferences and mouthparts of Mesozoic and recent Ptychopteridae are discussed. 相似文献

A new genus, Cretasyne gen. nov., in the family Lasiosynidae, with two species C. lata sp. nov. and C. longa sp. nov., is described from the Lower Cretaceous Yixian Formation of Inner Mongolia, China. These fossils are the first record of the family from the Yixian Formation and provide significant information on lasiosynid morphology and diversity. The fossil record of Lasiosynidae is also reviewed. 相似文献

A new fossil stick-insect (Phasmatodea) is described and figured from a male preserved in Cretaceous amber from Myanmar. Echinosomiscus primoticus Engel and Wang, gen. et sp. nov., is a robust, somewhat-compressed stick-insect bearing abundant acanthae over the head and body, and remarkably lacks an area apicalis on the tibiae. The species is described and assigned to a new, extinct subfamily of Phasmatidae s.l., as Echinosomiscinae Engel, subfam. nov. Brief remarks are made regarding the dating of phasmatodean lineages, with E. primoticus providing the first reliable evidence for Euphasmatodea and even Neophasmatodea in the Cenomanian. 相似文献

The new genus and species Angustaeshna magnifica of Burmaeshnidae is described on the basis of a new fossil from Burmese amber. The genus Cretaeshna from the same amber is transferred from the Telephlebiidae into the Burmaeshnidae. We redefine this last family, no longer considered as the sister group of the Late Cretaceous Enigmaeshnidae, but as putative sister group of the Telephlebiidae in the Aeshnoidea. No known fossil belongs to the Telephlebiidae. 相似文献

An inclusion in Cretaceous amber from Myanmar is described as a new fossil species in the extant liverwort genus Frullania. The name Frullania pinnata is proposed for the taxon that is characterized by entire underleaves paired with a conspicuous pinnate branching pattern, two distinctive and stable morphological features. Entire underleaves are known in several extant Frullania species but had not previously been documented in Frullania in amber. The combination of morphological characters in this new fossil species is unknown in any crown group lineage of Frullania, and may very well represent a stem lineage element of the genus. This discovery is important because it expands our understanding of the diversity of Frullaniaceae in the Burmese amber forest as well as important ramifications for the phylogenetic reconstruction of extant Frullania lineages. 相似文献

A second Mesozoic twisted-wing parasite (Strepsiptera) is described and figured based on an exceptionally well-preserved male in mid-Cretaceous (Cenomanian) amber from northern Myanmar. Phthanoxenos nervosus Engel and Huang, gen. et sp. nov., is distinguished from other strepsipteran lineages, particularly the contemporaneous Cretostylops engeli Grimaldi and Kathirithamby, also in Burmese amber, and Protoxenos janzeni Pohl et al. in mid-Eocene Baltic amber, and assigned to a new family, Phthanoxenidae Engel and Huang, fam. nov. Phthanoxenos exhibit features indicative of a more primitive phylogenetic position than Cretostylopidae but still more derived than Protoxenidae. Brief remarks are made on the geological history of the Strepsiptera. 相似文献

Rapid radiation of the Bittacidae during the Jurassic resulted in high diversity within this family of Mecoptera. More than 40 species within 23 genera have been described from this period. However, around the end of the Jurassic the abundance and diversity of Bittacidae decreased and only seven species in five genera are known to date from the Cretaceous. A new specimen from the basal Cretaceous of England, Tytthobittacus jarzembowski sp. nov., described here, represents the eighth species and the second fossil representative of this family from the European Cretaceous. This hangingfly belongs to an extant and relictual genus previously known only from Australia. The paper also includes a review of all known Cretaceous bittacids and a re-examination of European species Antiquanabittacus nanus Petrulevičius and Jarzembowski, 2004. 相似文献

Two new genera and two new species of fossil Throscidae: Potergosoma gratiosa gen. et sp. nov. and Rhomboaspis laticollis gen. et sp. nov. are described from the Lower Cretaceous Lebanese amber and are compared with extant and extinct genera. The described amber inclusions are the oldest known representatives of the family Throscidae. Some hypotheses on the phylogeny of the family Throscidae and the position of it in the superfamily Elateroidea are discussed. 相似文献
