A new genus and species of female phantom midge Neuseptychoptera carolinensis gen. et sp. nov. in the fossil subfamily Eoptychopterinae is described and illustrated; this ptychopterid is from Upper Cretaceous (Campanian) amber of North Carolina. This is the first member of Eoptychopterinae from North America and the first found in Campanian age amber. We propose to treat the extinct subfamily Eoptychopterininae Lukashevich, 1995, as a junior synonym of the subfamily Eoptychopterinae Handlirsch, 1906, syn. nov. The elongated mouthparts of the new species have broad labella, and these are functionally interpreted as feeders for honeydew, fermenting plant juices, and nectar rather than for biting. 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

An exotic wingless female insect in mid-Cretaceous Myanmar amber is described as Aethiocarenus burmanicus sp. et gen. nov. in the order Aethiocarenodea ord. nov. and family Aethiocarenidae fam. nov. The distinguishing feature of Aethiocarenus burmanicus sp. et gen. nov. is its unique head, the dorsum of which is shaped like an isosceles right triangle with the hypotenuse at the top and vertex positioned at the base of the neck. While insects with triangular-shaped heads are common today, the hypotenuse of the triangle is always located at the base of the head and attached to the neck, with the vertex at the apex of the head. Other features of the fossil are the long narrow, flat body, long slender legs, especially the hind pair that are twice the length of the abdomen, lack of wings, protruding eyes, paired ocelli, secretory glands located on the dorsum of the neck and swollen abdomen bearing paired segmented cerci. 相似文献

Revision of some North American Silurian callocystitid cystoids shows that Tetracystis Schuchert has the first two brachioles to the left in ambulacra B and D (B D different pattern), whereas Troosticystis Paul and Lovenicystis Regéll have only the first brachiole to the left in all four ambulacra (B–E the same pattern). ‘Apiocystites’ elegans Hall is transferred to Tetracystis because it has the B D different pattern. Lovenicystis kopfi sp. nov. is characterized by four short ambulacra. Salirocystis gen. nov. has the B D different pattern and two hydropores. All callocystitids that lack ambulacrum A are assigned to a new subfamily, the Tetracystinae; those with five ambulacra are referred to informally as ‘lepadocystines’. The previously recognized subfamily Callocystitinae is reduced in rank to a tribe within the ‘lepadocystines’. Preliminary character analysis suggests that the loss of ambulacrum A was the most significant evolutionary event within the family Callocystitidae, but has been overlooked in taxonomy. Character analysis also shows that all ‘lepadocystines’ had the B D different pattern of primary brachioles, which is retained in four tetracystine genera, Lepocrinites Conrad, Sphaerocystites Hall, Tetracystis and Salirocystis. Since Salirocystis has the plesiomorphic B D different pattern plus the apomorphic double hydropore, one cannot define a monophyletic taxon characterized by the B–E the same pattern plus one characterized by a double hydropore. Both alternatives are equally parsimonious. Here a new monophyletic tribe Lipsanocystini is defined characterized by a double hydropore. The B–E the same pattern evolved independently twice. Among current characters the loss of ambulacrum A, development of the B–E the same pattern and development of two hydropores are the most significant evolutionary events. Number of periproct border plates, length and structure of ambulacra are less significant. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

A new genus and species of Trichomyiinae (Axenotrichomyia boisteli) is described herein from Burmese Upper Cretaceous (Cenomanian) amber. This new taxon is characterized, illustrated, and its taxonomic position is discussed. This discovery sheds new light for the understanding of the palaeobiodiversity of this group. 相似文献

Xenotrichomyia newjerseyiensis a new genus and species belonging to Trichomyiinae within Psychodidae is characterized, described, illustrated and its taxonomic position is discussed. It shares some similarities with Trichomyiinae of group B, but retains some archaic features, such as normal and non-excentric flagellomeres, and possesses an autapomorphy in wing venation that distinguish it from all remaining Trichomyiinae. This discovery represents the first Trichomyiinae (Psychodidae) from the Upper Cretaceous New Jersey amber, and adds more evidence on the very high palaeodiversity of the psychodids since at least the Lower Cretaceous. An updated check list of fossil Trichomyiinae is given. 相似文献

Avenaphora gallica sp. nov., second representative of this dolichopodid genus, and Cretomicrophorus piolencensis sp. nov., third representative of this genus, are described from a new lower Santonian amber outcrop in Southern France. The relationships of Avenaphora in the Empidoidea are discussed. Avenaphora gallica and Cretomicrophorus piolencensis were found in a marine littoral swamp palaeoenvironment, as for many modern Parathalassiinae. 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

Annulipsyllipsocus andreneli gen. et sp. nov. and A. inexspectatus gen. et sp. nov., the first records of the Psyllipsocidae from the Cretaceous amber of Myanmar are described, illustrated and their taxonomic position discussed. The new genus is characterized by antennae with 16 segments; flagellomeres with secondary annulations; radial cell closed, five-angled, bulged on its R1 border; triangular pterostigma. Species belonging to Annulipsyllipsocus gen. nov. are polymorphic. The described taxa represent the earliest evidence for polymorphism in Psocodea. A checklist of all known species of Psyllipsocidae is given. 相似文献

New Fossil Xyelidae (Insecta, Hymenoptera) from the Yixian Formation of Western Liaoning, China 总被引：1，自引：0，他引：1
In this paper one new genus and two new species, Brachyoxyela brevinodia sp. nov. and Brachyoxyela gracilenta sp. nov., in the subfamily Macroxyelinae of the family Xyelidae, are described and illustrated. The specimens were collected from the Yixian Formation, the Upper Jurassic to Lower Cretaceous, of Beipiao City, Liaoning Province, northeastern China. The new genus is established based on the characters that vein Sc meets R only beyond origin of Rs, third antennal segment is almost equal in length to the rest flagellomeres combined, terminal flagellomeres increasingly shortened toward apex, and vein 2r-rs inclined toward the apex of wing. 相似文献

The Bittacidae (hangingflies) were abundant and widespread during the Mesozoic, but much of their diversity falls within the Jurassic whereas in the Cretaceous they are less common. A new bittacid, Burmobittacus jarzembowskii gen. et. sp. nov., is described from mid-Cretaceous amber from northern Myanmar. This new find is the first bittacid from Burmese amber and also the first Mesozoic bittacid preserved in amber. The new genus is distinguished from all known bittacids in having a long and narrow wing with Rs arising from R and forking very early (in the basal one-fourth of the wing), resulting in the stem of Rs being very short (about 1/8th of the length of Rs1+2), and stems of the main branches of Rs (Rs1+2 and Rs3+4) being unusually long. 相似文献

The third Cretaceous Aeshnoptera in amber is described from Myanmar. It represents a new family Burmaeshnidae fam. nov., genus and species Burmaeshna azari gen. et sp. nov. Its exact affinities remain uncertain but it is probably the sister group of the Late Cretaceous family Enigmaeshnidae. This discovery supports the hypothesis of an intense period of appearance of many aeshnopteran subclades during the late Early Cretaceous and the Late Cretaceous. 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

The rhagionid Lebanoleptis huangi gen. et sp. nov. is described from the Lower Cretaceous amber of Lebanon. It is characterized, illustrated, and compared with the recent and fossil genera having the same particular absence of wing vein M3. Other Mesozoic flies with similar venation and currently attributed to the Rhagionidae are briefly discussed and should be revised. 相似文献
