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

A new species of Elcanidae (Orthoptera: Elcanoidea), Panorpidium yixianensis sp. nov., is described based on two new specimens from the Lower Cretaceous Yixian Formation of northeastern China. It differs from other species in forewing characters and spines on the hind tibiae. In addition, a new specimen Burmelcana sp., is described and figured based on an amber inclusion from the mid-Cretaceous Burmese (Myanmar) amber. P. yixianensis sp. nov. represents the first definite record of Elcanidae in the Early Cretaceous Jehol biota, and Panorpidium is the only genus of Ensifera to be found in the Early Cretaceous faunas of England, Russia and China. 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

Three new caddisflies species are described and illustrated from the mid-Cretaceous Burmese amber: Wormaldia cretacea sp. nov., W. resina sp. nov. (Philopotamidae) and Neureclipsis burmanica sp. nov. (Polycentropodidae). Palerasnitsynus ohlhoffi (Psychomyiidae) is re-described based on new fossils. Wormaldia are common in Burmese amber, and its diversity shows that this genus had very ancient origin and diversified at least during the mid-Cretaceous. N. burmanica sp. nov. is the oldest record of Neureclipsis, revealing this genus originated at least in the mid-Cretaceous. So far, six extinct species representing the small Order Trichoptera have been found in Burmese amber. 相似文献

The genus Mesosticta Huang, Azar, Cai et Nel, 2015 was established based on the wing bases of two damselflies from mid-Cretaceous Burmese amber. Here we describe a new well-preserved platystictid damselfly, Mesosticta electronica sp. nov., with complete forewings and hindwings. The diagnosis of Mesosticta is revised and augmented in this paper. Mesosticta electronica sp. nov. differs from Mesosticta burmatica Huang, Azar, Cai et Nel, 2015 in having the arculus slightly distal of Ax2, a free subdiscoidal cell, the hindwing AA ending on the middle area of the posterior side of the discoidal cell, and the base of RP2 being three or four cells distal of the subnodus. The new discovery adds to the diversity of damselflies in mid-Cretaceous Burmese amber and puts the origin of Platystictidae to at least the mid-Cretaceous. 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

A new subfamily, Burmadysagrioninae Zheng, Wang and Nel, subfam. nov., for the genus and species Burmadysagrion zhangi Zheng, Wang and Nel, gen. et sp. nov. is described from mid-Cretaceous Burmese amber. This is the third dysagrionid damselfly from the Mesozoic and the second one from Burmese amber. The new specimen has a unique discoidal cell with the anterior and posterior sides not parallel, and the basal side longer than the distal side, unlike the typical ‘sieblosiid-dysagrionine’ type. It differs from other dysagrionid damselflies by the presence of a simple wing venation, the vein IR1 originating below the pterostigma and a special discoidal cell. 相似文献

Oxyporinae is a distinct staphylinid subfamily characterized by a large body, remarkably long and projecting mandibles, and large, crescent-shaped terminal labial palpomeres. Previously, only three compression fossils from the Lower Cretaceous Yixian Formation in China were known for the subfamily from the Mesozoic Era. This study describes a remarkable new species, Oxyporus cretaceous sp. nov., based on a single specimen in Upper Cretaceous Burmese amber. This finding is the earliest record of Oxyporinae preserved as amber inclusion. The well preserved mouthparts suggest that mycophagous feeding habits had already been acquired by the mid-Cretaceous. 相似文献

A new tetraphalerin beetle, Tetraphalerus lindae sp. nov. (Insecta: Coleoptera: Archostemata) is described from mid-Cretaceous Burmese amber from northern Myanmar. This is the first species of this Jurassic-recent genus of archaic beetles to be described from amber inclusions, and is the first tetraphalerin cupedid from Burmese amber. This small, unusual Cretaceous Tetraphalerus is considered to belong to the T. bruchi species group of this now relict South American genus. 相似文献

A new species belonging to the extant dermestid genus Attagenus, Attagenus burmiticus sp. nov., is described and illustrated based on a well-preserved specimen from the Upper Cretaceous Burmese amber. The discovery suggests that Attagenus is an ancient group, originating as early as in the mid-Cretaceous. Along with another species of Attagenus known from the Upper Cretaceous New Jersey amber, it implies that Attagenus were widespread in the Mesoozic. 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

A new species of Glaesoconis Meinander (Neuroptera: Coniopterygidae) from the Santonian Taimyr amber
Glaesoconis popovi sp. nov. (Neuroptera: Coniopterygidae) is described from Upper Cretaceous (Santonian) Taimyr amber of northern Siberia (Yantardakh locality). The new species may be distinguished from others in the genus by much smaller eyes and the shape of the terminal segment of the maxillary palpus. The generic affinity of Glaesoconis baliopteryx Engel, 2004 from the mid-Cretaceous Burmese amber needs confirmation. 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

We describe two new species of extinct biting midges in the fossil genus Protoculicoides: Protoculicoides hispanicus Szadziewski and Arillo, sp. nov. and Protoculicodes sanjusti Szadziewski and Arillo, sp. nov., from Albian (101–113 Ma) amber of San Just, Spain. Atriculicoides Remm, 1976 is recognized as a new junior synonym of Protoculicoides Boesel, 1937 (NEW SYNONYM). Devalquia Choufani et al., 2013 is regarded here as a new junior synonym of the extant genus Culicoides Latreille, 1809 (NEW SYNONYM). Metahelea roggeroi Choufani et al., 2013 from Upper Cretaceous French amber, is excluded from the tribe Heteromyiini and placed in the extant genus Stilobezzia Kieffer, 1911, tribe Ceratopogonini: Stilobezzia roggeroi (Choufani et al., 2013), comb. nov. The extinct tribe Atriculicoidini Szadziewski, 1996 is regarded as a new subfamily, Atriculicoidinae, stat. nov., that includes the fossil genus Protoculicoides, with 13 species reported from Albian, Turonian, Cenomanian, Coniacian, Santonian and Campanian ambers (78–113 Ma). Protoculicoides skalskii Szadziewski & Arillo, 1998 from Lower Cretaceous amber of Álava, Spain, Protoculicoides succineus Szadziewski, 1966 from Lower Cretaceous Lebanese amber and Protoculicoides burmiticus Szadziewski & Poinar, 2005 from Upper Cretaceous Burmese amber are transferred to the extinct genus Archiculicoides Szadziewski, 1996, comb. nov. Protoculicoides krzeminskii Choufani et al., 2014 from Lower Cretaceous Lebanese amber is transferred to the extinct genus Archiaustroconops Szadziewski, 1996, comb. nov. The Cretaceous subfamily Atriculicoidinae forms an unresolved trichotomy with the extant subfamilies Forcipomyiinae and Dasyheleinae, both of which date to the Eocene. The fossil record indicates that wings with macrotrichia in biting midges evolved during the mid-Cretaceous greenhouse climate. We suggest that this was an evolutionary adaptation to new atmospheric conditions with higher levels of CO2 in order for the antennal Johnston's organs of males to receive the vibrational sex signals produced by females during flight. 相似文献

A new family of aphids, the Isolitaphidae fam. nov. (Hemiptera: Aphidoidea), is described for the new genus and species, Isolitaphis prolatantennus gen. et sp nov., in mid-Cretaceous amber from Myanmar (Burma). The new species is compared with previously described Mesozoic Aphidoidea, including members of the families Parvaverrucosidae and Burmitaphididae that were described earlier from Myanmar amber. The new taxon can be separated from all previously described extant and extinct Aphidoidea by its 10-segmented antenna, the presence of an ovipositor, siphons, a three-branched M vein and forked C vein. The new species adds to the morphological diversity of Mesozoic Aphidoidea. 相似文献

A new weevil, Aepyceratus hyperochus gen. et sp. nov., Aepyceratinae subfam. nov., is described from mid-Cretaceous Burmese amber. The new subfamily differs from the previous Mesozoic subfamilies Brenthorrhininae, Eobelinae, Cretonemonychinae and Paleocartinae by the short lateral pronotal carina, stark convex eyes and basal antennal insertion. From the subfamilies Rhinorhynchinae and Cimberidinae, it is distinguished by the short lateral pronotal carina, exodontous mandibles and basal antennal insertion. The new subfamily differs from the subfamily Idiomacerinae by the distinct clypeolabral suture, elliptical protruding eyes, short antennomere 1, wide tarsi, short lateral carina on the pronotum, and exodontous mandibles. 相似文献

Cretoboganium gei gen. et sp. nov., a new amber inclusion of the cucujoid family Boganiidae is described and figured based on a well-preserved adult from the mid-Cretaceous Burmese amber (Hukawng Valley, northern Myanmar), some 99 million years ago. Based on the presence of a pair of pronotal callosities, Cretoboganium can be firmly placed in the extant subfamily Boganiinae, a small group currently comprising two small austral genera. Our discovery represents the first fossil record for Boganiinae. It also demonstrates another example that an apparently austral group may have its sister group occurred in today’s northern hemisphere. Together with the other fossil boganiid known from the Middle Jurassic of China, the finding suggests that Boganiidae is an ancient and relict group. Moreover, the present biogeographic distribution of Boganiinae is indicative of an earlier origin of this subfamily, which likely originated before the breakup of the Gondwanan supercontinent. 相似文献
