Two new genera from the Lower Cretaceous Yixian Formation of Beipiao City, Liaoning Province, northeastern China are described and illustrated. Paracretocateres gen. nov. (type species P. bellus, sp. nov.) and Yixianteres gen. nov. (type species Y. beipiaoensis sp. nov.) are assigned to the subfamily Lophocaterinae based on the state of the procoxae which are not projecting, the transverse procoxal cavities, and the exposed protochantins. The new taxa broaden the diversity of this family and provide further morphological characters for phylogenetic studies of Trogossitidae. They also provide evidence that lophocaterines well-diversified prior to the trogossitines and their biologies may have been similar to extant forms. 相似文献

Four new, monotypic genera of Aleyrodidae from the Lower Cretaceous Lebanese amber are described: Shapashe aithiopa gen. sp. nov.; Milqartis azari gen. sp. nov.; Aretsaya therina gen. sp. nov.; and Yamis libanotos gen. sp. nov. All new taxa represent subfamily Aleurodicinae. The key for identification of genera of Aleurodicinae from the Lebanese amber is provided. The morphological features of newly established taxa are discussed. The importance of the fossils for phylogenetic, evolutionary and ecological studies is presented. 相似文献

A new subfamily of Ichneumonidae, Novichneumoninae subfam. nov., is established based on two new genera with two new species: Novichneumon longus gen. et sp. nov. and Caloichneumon perrarus gen. et sp. nov. These two new species are the first ichneumonids described from the Upper Cretaceous Myanmar (Burmese) amber. A list of all described Mesozoic ichneumonid fossil species with their respective localities and ages is summarized. The distribution of Ichneumonoidea during the Cretaceous indicates that Cretaceous ichneumonids were documented from localities at high latitudes while braconids were distributed worldwide, a pattern consistent with the distribution of extant ichneumonids and braconids. 相似文献

Two new genera and species of Cretaceous webspinners (Embiodea) are described and figured, both preserved in amber from northern Myanmar. Atmetoclothoda orthotenes Engel and Huang, gen. et sp. nov., is the first fossil representative of the putatively primitive family Clothodidae, and is segregated into its own subfamily, Atmetoclothodinae Engel and Huang, subfam. nov., owing to its primitive retention of a distinct mentum, a quadrate submentum with straight borders, a postocciptal suture that meets the hypostomal sulcus at the posterior tentorial pit, and subgenae that do not meet medially (thus a ventral bridge or gula is lacking), completely symmetrical terminalia, and unsegmented cerci that apically bear a small inner lamellar projection. Litoclostes delicatus Engel and Huang, gen. et sp. nov., is the first definitive fossil of Oligotomidae (not including a subfossil species in Pleistocene copal and which is likely synonymous with an extant taxon), and differs from modern genera in a combination of head, tarsal, and terminalic morphology. The new fossil species double the known Cretaceous fossils and add a further two families to the Mesozoic record for the order. 相似文献

James E. Jepson Vladimir N. Makarkin Edmund A. Jarzembowski 《Cretaceous Research》2009,30(5):1325-1338
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

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

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

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

Two new genera and three new species of the Mesozoic family Aeotheogrammatidae are described from the Lower Cretaceous of Yixian Formation (Liaoning Province, China): Cyclicogramma rotundum gen. et sp. nov. and Aetheogramma bistriatum sp. nov. from Huangbanjigou, and Curtogramma ovatum gen. et sp. nov. from Dawangzhangzi. The hind wing of Cyclicogramma rotundum gen. et sp. nov. differs from that of other species by its smaller size, its overall shape, RP bearing only two oblique radial branches, and its configurations of CuP, AA1, and AA2. Aetheogramma bistriatum sp. nov. is closely related to A. speciosum Ren and Engel, 2008, but distinguished from the latter by its distinctive configuration of RP1, and the narrower and longer AA2 space in the hind wing. Curtogramma ovatum gen. et sp. nov. is distinguished from all other species of the family by the forewing with M forking very far from the wing base. 相似文献

The fossil snakefly family Baissopteridae from the Lower Cretaceous (upper Barremian) of the Yixian Formation of Liaoning Province, China is reviewed. Two genera and five species of Baissopteridae are recorded, including a new genus, namely Microbaissoptera gen. nov., and three new species, i.e., Baissoptera bicolor sp. nov., Baissoptera sinica sp. nov., and Microbaissoptera monosticha sp. nov. Moreover, Baissoptera euneura Ren, 1997 is herein treated as a new junior synonymy of Baissoptera grandis Ren in Ren et al., 1995. Baissoptera minima Ponomarenko, 1993 is transferred to the presently described new genus Microbaissoptera gen. nov. based on the small body-size and the presence of a single gradate series of crossveins in radial and medial areas of posterior part of both fore- and hind wings. A key to genera of Baissopteridae is provided. 相似文献

Two new genera with two new species in Berothidae, Maculaberotha nervosa gen. et sp. nov. and Magniberotha recurrens gen. et sp. nov., are described from Upper Cretaceous Myanmar (Burmese) amber. Based on the new specimens of the same species, we propose some venational characters as intraspecific variations, e.g., the markings on the wings and crossveins in the radial sector. We also study and compare the female genital sclerites from three genera of Haploberotha, Dasyberotha, and Jersiberotha to highlight the importance of using these characters preserved in amber for taxonomic and phylogenetic studies. Furthermore, an updated key to the berothid genera of Myanmar amber is provided. 相似文献

A new genus with two new species, Orentalphila gravia gen. et sp. nov. and O. caloa sp. nov., and three new species in two known genera, Sinosciophila angustia sp. nov., Sinosciophila seboa sp. nov. and Similsciophila undulata sp. nov., are described from the Lower Cretaceous of Yixian Formation at Huangbanjigou, Beipiao City, western Liaoning, China. These new taxa, representing the first records of mesosciophilids from this locality, provide morphological information and diversity for Mesosciophilidae in the Early Cretaceous. An updated key to known genera of Mesosciophilidae is provided. In addition, according the generic diagnosis revised by Zhang, 2007, Mesoplecia antiqua Hao and Ren, 2009 should be transferred to Mesosciophila Rohdendorf, 1946. 相似文献

Our results present a taxonomic and palaeoecological study on non-marine gastropods from the latest Cretaceous to Paleocene deposits of the Pingyi Basin, Shandong Province, eastern China. These gastropods are systematically described: three species belonging to three genera including Physa dongtaiensis Gu, 1989, Hydrobia datangensis Yü, 1977, and the newly established species Cyathopoma pingyiensis sp. nov.; two indeterminata genera and species including Truncatelloidea gen. et sp. indet., and Pomatiopsidae gen. et sp. indet. Among them, Truncatelloidea gen. et sp. indet. and Cyathopoma pingyiensis sp. nov. are the dominant species with the longest record. Cyathopoma pingyiensis, sp. nov. is the earliest representative of this widely distributed Asian extant genus. Sedimentological facies analysis of the gastropod-bearing beds suggested that Truncatelloidea gen. et sp. indet. lived in a small pond with a river inlet and a shallow lake, while Ph. dongtaiensis, ?Pomatiopsidae gen. et sp. indet, and ?H. datangensis only thrived in the shallow lake. Cyathopoma pingyiensis sp. nov. inhabited the land area around the shallow lake. Our results showed that no significant species change of the gastropod fauna across the K/Pg (Cretaceous/Paleogene) boundary was observed in the Pingyi Basin. 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
