The Cretaceous lacewing family Babinskaiidae comprises nine species in seven genera, of which two new genera and one new species are described herein: Parababinskaia elegans gen. et sp. nov. from the late Aptian Crato Formation of Brazil, and Pseudobabinskaia gen. nov. (with the only species Pseudobabinskaia martinsnetoi Lu et al., 2017, comb. nov.) from mid-Cretaceous Burmese amber. The reduction of the veins AA2 and AA3 in the hind wing is an autapomorphy of the family. Babinskaiidae are most closely related to Nymphidae, and have probably evolved as a side branch of these. The superfamily Myrmeleontoidea is divided into two epifamilies: Nymphidoidae whose MP (or M) is long, not fused with CuA, and trichosors are present (Nymphidae, Babinskaiidae), and Myrmeleontoidae whose MP is crossvein-like, then fused with CuA, and trichosors are lost (Araripeneuridae, Ascalaphidae, Myrmeleontidae, Nemopteridae, Palaeoleontidae). The aligned crossveins 1r-m and 1m-cu in the forewing is probably the only venational autapomorphy of the Myrmeleontoidea. 相似文献

Paradoxosisyra groehni gen. et sp. nov. (Neuroptera: Sisyridae) is described from Upper Cretaceous (lowest Cenomanian) Burmese amber as the oldest known sisyrid. The new genus is assigned to the new subfamily Paradoxosisyrinae, which is characterized by enormously long siphonate mouthparts, very long and slender hind legs, several setiferous calluses on the head and pronotum; deeply forked CuP and AA1 veins in the forewing; a complete inner gradate series of crossveins, and the RP vein with five branches in the hind wing. The greatly lengthened, laterally flattened galea and lacinia, and the labial ligula transformed into a long acute stylet are characteristic of only this species and do not occur in other insects. These siphonate mouthparts were likely used primarily to feed on flower nectar. The possibility remains, however, that the species was hematophagous (possibly facultative), feeding on the hemolymph of arthropods or the blood of such thin-skinned vertebrates as frogs. 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

Ascalochrysa megaptera gen. et sp. nov. is described from the Yixian Formation (Lower Cretaceous) of China. It is treated as belonging to the new family Ascalochrysidae fam. nov., closely related to Mesochrysopidae but easily distinguished from it in the hindwing venation features: e.g., numerous subcostal crossveins; branches of Rs widely, irregularly spaced and deeply branched; crossvenation rich, irregular; convex vein-like fold (‘M5’) before concave CuA present. The presence of well-developed ‘M5’ in the hind wing is interpreted to be plesiomorphic condition within the order. Ascalochrysidae are considered the sister group of Mesochrysopidae (s.l.). 相似文献

The family Mesopsychidae Tillyard,1917 presently consists of ten described genera from the Early Permian to the Early Cretaceous of Australia,China,Kyrgyzstan,Russia,South Africa,Tajikistan,and Ukraine.Herein,a new genus and a new species of fossil mesopsychid,Epicharmesopsyche pentavenulosa gen.et sp.nov.,is described from the Middle Jurassic Jiulongshan Formation of Inner Mongolia,China,supplementing the family-level diversity.The well-preserved,new material reveals many characters,including antennae,wing venation,shape and genitalia that increase our morphological understanding of the family,although unfortunately the mouthparts and most of the legs are not preserved.Diagnosis of the Mesopsychidae is emended to include a four-or five-branched MP in both the fore-and hind wings.This is the first documentation of a wing coupling structure in the Mesopsychidae,consisting of three to four frenula bristles on the humeral lobe at the base of the costal margin of both hind wings.Asymmetrical shape and size of the left and right wings on a specimen of E.pentavenulosa gen.et sp.nov.,seems to be a common condition for mesopsychid taxa from northeastern China. 相似文献

Eight new genera and thirteen new species of lacewings (Neuroptera) are described from the Lower Cretaceous Wealden Supergroup, Weald Sub-basin: Principiala rudgwickensis sp. nov. (Ithonidae), Stenomylina medialis gen. et sp. nov., Protosmylina bifasciata gen. et sp. nov. (Osmylidae), Cretapsychops corami gen. et sp. nov., Micropsychops parallelus gen. et sp. nov., Valdipsychops logunovi gen. et sp. nov., V. brigidae gen. et sp. nov., V. maculosus gen. et sp. nov., V. proudlovei gen. et sp. nov., V. minimus gen. et sp. nov., Psychopsites rolandi gen. et sp. nov. (Psychopsidae), Actinophlebioides valdensis gen. et sp. nov. and Protohemerobius perexiguus gen. et sp. nov. (Neuroptera familia incertae sedis). Psychopsidae are shown to dominate the neuropteran fauna, while the presence of Brongniartiellidae has not been confirmed in the Wealden, due to previously thought representatives of this family being in fact psychopsids. This is the first fossil record of Ithonidae and Osmylidae in Britain. The range of Kalligrammatidae has been extended in the Cretaceous of Britain from the mid-Valanginian to early Barremian. 相似文献

Christophus myanmarensis gen. et sp. nov., Christophus ohmkuhnlei gen. et sp. nov., and Mintara parva gen. et sp. nov., three new species and two new genera of belytine wasps (Diapriidae: Belytinae) are described and figured from males preserved in mid-Cretaceous Kachin (Burmese) amber. These new fossils enrich the fossil record of Cretaceous diapriids, summarized here, demonstrating the diversity of the family before the K/Pg extinction and suggesting an older origin for the family. 相似文献

The lacewing family Ithonidae is reported from the mid-Cretaceous amber of Myanmar for the first time. A new genus and species, Burmithone pennyi gen. et sp. nov., is herein described based on an almost completely preserved female specimen. The new genus exhibits a number of remarkable forewing characters, such as the proximal branches of RP vein fused with the MA vein and the peculiar configuration of MP and CuA. The systematic position of Burmithone gen. nov. is briefly discussed in comparison with other genera of Ithonidae. 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

Palaeoperilestes electronicus gen. et sp. nov. is the first perilestid damselfly described from mid-Cretaceous Burmese amber. This new damselfly can be attributed to the family Perilestidae by the midfork being distal of the subnodus and the base of IR2 quite near to the base of RP2, both features found in the extant genera Perilestes and Perissolestes. Palaeoperilestes electronicus gen. et sp. nov. has a strongly zigzagged IR1, however, differing from Perilestes and Perissolestes which have a straight IR1. The discovery not only adds to the diversity of damselflies in Burmese amber, but also puts the origin of Perilestidae back to at least the mid-Cretaceous. 相似文献

A new genus and species of aphids, Tanyaulus caudisetula gen. et sp. nov. (Hemiptera: Aphidoidea: Burmitaphidae), is described from mid- Cretaceous Myanmar amber. Autapomorphies for the new genus are stub-like hind wings, 7-segmented antenna, long rostrum equal to body length, 4 veins departing from the main vein, cubital veins distinctly separated, with a very short, curved basal proximal cubitus, one-branched M vein with distal fork arched at the base, distinct claval folds at wing bases and caudal protuberance with extended setae. The new fossil adds to our knowledge of the morphological diversity of Mesozoic Aphidoidea. 相似文献

Two new peculiar mid-Cretaceous braconid genera, Megalyrhyssalus gen. nov. (type species Megalyrhyssalus clavicornis sp. nov.) and Stephanorhyssalus gen. nov. (type species Stephanorhyssalus longiscapus sp. nov.), are described and illustrated from Burmese amber. According to the particular morphology and wing venation of Megalyrhyssalus gen. nov. a new subfamily Megalyrhyssalinae subfam. nov. is created. The subfamily Seneciobraconinae is synonymised under Protorhyssalinae (syn. nov.). Additionally, a key to the genera of Braconidae having second recurrent vein (2m-cu) in forewing is provided. 相似文献

Four new Trichoptera species: Kliganigadukia taymyrensis gen. et sp. nov. (Hydrobiosidae), Archaeopolycentra yantardakh sp. nov. (Polycentropodidae), Taymyrodipseudon protopegasus gen. et sp. nov. (Dipseudopsidae), and Siberoclea parapolaria gen. et sp. nov. (Leptoceridae) from Late Cretaceous amber (Santonian, Kheta Formation, 85 Ma) of Taymyr (Siberia, Russian Federation) are described and illustrated. Data on the Cretaceous amber Trichoptera (13 families, 20 genera, 29 species) are summarized and discussed. 相似文献

Prosisyrina sphinga sp. nov. (Neuroptera: Sisyridae) is described from Upper Cretaceous (Santonian) Taimyr amber of northern Siberia (Yantardakh locality). The new species is preliminary assigned to this Cretaceous genus, mainly based on character states of the maxillary palpus and the hind wing vein M and crossvein 1r-m, and the presumable absence of tibial false spurs. However, the structure of the costal space and the RP branching in the hind wing indicate that it may belong to a new, closely related genus. The discovery of this second species from the locality might suggest that sisyrids were usual members of the Santonian riparian biocenoses of northern Siberia. 相似文献

A new genus and species, Similinannotanyderus lii gen. et sp. nov., is described from Myanmar amber. It differs from other genera of Tanyderidae based on special characters of wing venation and male genitalia. This new taxon broadens the diversity of Tanyderidae in the Cretaceous, and its morphological characters enhance our understanding of the development and evolution of the primitive crane flies. 相似文献

A new genus and species, Gracilipygia canaliculata gen. et sp. nov., in the family Pygidicranidae of Dermaptera is described from the Upper Cretaceous Myanmar amber. The new species is assigned to the subfamily Pyragrinae mainly based on the following characters: broadly separated cercal forceps without segmentation and the posterior abdominal tergum with mediolongitudinal furrow and lateral ridges. The G. canaliculata gen. et sp. nov. is the earliest record hitherto for the subfamily Pyragrinae, and probably represents a stem taxa of Pyragrinae. 相似文献
