Ponomarenkylon alexandri gen. et sp. nov. (Melittommatinae) from the Late Eocene Baltic amber is described. The long filiform antennae and the apparent absence of sensillary organs, which are frequently present on modified maxillary palps in other lymexylids, are evidence of the primitive state of the new genus. 相似文献

Alicodoxa rasnitsynigen. et sp. n. (Dictyopharinae: Orthopagini) is described based on a nymph from Rovno amber; it also occurs in Baltic amber. A small additional wax plate dorsal to the large wax plate of abdominal tergites VI-VIII is first reported in this and other genera of Dictyopharidae. A lectotype is designated for Pseudophana reticulata Germar & Berendt, 1856 transferred to Protepiptera (Achilidae): Protepiptera reticulata (Germar & Berendt, 1856), comb. n. 相似文献

A new genus and species, Olemehlia krali n. g. & n. sp. (Coleoptera: Ripiphoridae: Ripidiinae), is described from Baltic amber. The newly described genus is compared with all known fossil and extant closely related genera of the subfamily Ripidiinae. It is characterised by the following combination of characters: antennae consisting of 10 antennomeres, with scape, pedicel, and antennomere 3 simple and antennomeres 4–10 uniflabellate, mouthparts reduced to a small single unpaired tubercle, postocular ommatidia absent, pronotum trapezoid without grooves or impressions, elytra without white apical spots, tarsal formula 5–5–4, hind tarsomere I shorter than three remaining combined. Diversity of Ripiphoridae in Baltic amber is discussed; key to Ripidiinae genera from Baltic amber is provided. 相似文献

The first fossil of the staphylinine tribe Diochini Casey is described and figured from an inclusion in mid-Eocene (Lutetian) Baltic amber. Diochus electrussp. n. is distinguished from its congeners and the diversity of rove beetles (Staphylinidae s.l.) is summarized briefly. 相似文献

A new species of the extinct bee genus Ctenoplectrella Cockerell (Megachilinae: Ctenoplectrellini) is described and figured from two females preserved in middle Eocene (Lutetian) Baltic amber. Ctenoplectrella phaetonsp. n. is distinguished from its congeners on the basis of its body proportions, integumental sculpturing, wing venation, and pubescence, and is one of the more distinctive members of the genus. A revised key to the species of Ctenoplectrella is provided. 相似文献

Examination of fossil ant specimens from various private and institutional German collections of Baltic amber has revealed a new genus and species of Myrmicinae, described here as Thanacomyrmex hoffeinsorum gen. et sp. nov. The new worker morphotype shares some similarities with the coeval extinct genus Parameranoplus Wheeler, also from Baltic amber, and the extant genera Pristomyrmex Mayr and Acanthomyrmex Emery, suggesting placement of the new fossil in the Myrmecina genus-group within the tribe Crematogastrini. The new genus highlights the tremendous diversity of ants that evolved in the Palaeogene European forests and composed the first major radiation of crown-group ants. 相似文献

The new genus and new species of seed beetles (Copeoptera, Chrysomelidae, Bruchinae) Electrocaryedon poinari gen. et sp. nov. are described from the Late Eocene Baltic amber. This new genus differs from the genus Caryedon Schoenherr, 1823 in the completely separate procoxal cavities, not shortened lateral carina on pronotum, and wider body with sparse setae. 相似文献

A new extinct rove beetle, Palaeomesoporus electiricus gen. et sp.n., is described from a single specimen of Eocene Baltic amber. This fossil beetle is placed in the tribe Mesoporini, a ‘basal’ group of the mega-diverse subfamily Aleocharinae. Palaeomesoporus is easily discriminated from other mesoporine genera due to its less-developed antennal club, longer and slender elytron lacking a sinuate posterior margin, and prominently shorter mesotarsus. This finding sheds light on the paleodiversity and evolutionary history of the tribe and ‘basal’ Aleocharinae. 相似文献

A micropterous female embolemid is recorded in middle Eocene Baltic amber. Embolemus excitus Perrichot and Engel, sp. nov., is easily distinguished from other extinct and living species by the pronotum with only a weak mediolongitudinal furrow and with a lateral carina along the edge anterior to tegula, the mesopleuron with a pronounced medial dorsoventral carina, and the propodeum with dorsoposterior corners tuberculate. The new species also uniquely combines greatly reduced compound eyes, a scape distinctly elongate, the pronotum twice as long as mesoscutum, and the forewings extending at most to the anterior border of the second metasomal tergum. 相似文献

The beetle Mordellaria friedrichi sp. nov. is described from the Baltic amber. The new species differs from extant species of the genus in the shape of the eyes and antennae and in the ratios of the length of the pygidium and length of the elytron, pronotum, and anal sternite. 相似文献

Ten new species of caddisflies of the families Polycentropodidae (nine) and Molannidae (one) are described from the Eocene Baltic amber: Holocentropus peregrinator sp. nov., H. proximorepertus sp. nov., H. dugoi sp. nov., H. fundamentalis sp. nov., H. telergon sp. nov., Plectrocnemia varigoria sp. nov., P. synthesia sp. nov., P. novokshonovi sp. nov., Nyctiophylax valideturbidus sp. nov., and Molanna okraina sp. nov. 相似文献

A new genus and species of the cockroach family Blattulidae, Ocelloblattula ponomarenkoi gen. et sp. nov., are described from the Early Cretaceous Lebanese amber. In the wing venation, the new genus is extremely similar to the Jurassic genus Blattula Handlirsch, differing from the latter in a number of characters in its body structure. This find reveals much about the body structure of the extinct family Blattulidae, which is related to ancestors of the suborders Mantina and Blattina. 相似文献

Stenommatomorphus hexarthrus gen. et sp. nov. (Dryophthoridae: Stromboscerinae) is described from the Late Eocene Rovno amber. This is the first fossil
representative of the subfamily. The new genus is most close to Synommatus Pascoe, from which it differs in the pronotum and elytra less coarsely sculptured, the intervals not carinate, and the scutellum
present. 相似文献

The first fossil nemonychid (Nemonychidae) in Burmese amber, belonging to the subfamily Rhinorhynchinae, is described and figured as Burmonyx zigrasi Davis & Engel, gen. n. and sp. n. While this specimen also comprises the first definitive record of the subfamily in the Asian continent, other compression fossils exist at least from the Yixian Formation of China and the Karatau site of Kazakhstan which may also deserve placement within this group. Although several important areas of the body are obscured by the shape and fragmented condition of the amber piece, a sufficient number of features are visible to consider adequate placement within Rhinorhynchinae, including the fairly strongly punctate elytral striae and appendiculate, nearly bifid pretarsal claws. 相似文献

A new genus, Succinometrioxena n. gen., and a new species, S. poinari n. sp. (Metrioxenini: Oxycoryninae), are described from Baltic amber. This new genus resembles the recent genus Wallacexena Legalov, 2009 but differs from it by the frons with horn-like tubercles on either side, the absence of a middle pronotal carina, teeth on the side of the pronotum, the anterior margin of the pronotum lacking teeth and two long carinae on the elytra. From the fossil genus Paltorhynchus Scudder, 1893 the present fossil differs by possessing a frons with horn-like tubercles on either side, the absence of a middle pronotal carina, teeth on the sides of the pronotum, two long carinae on the elytra and short temples. From the fossil genus Archimetrioxena Voss, 1953, the new genus differs by the frons with horn-like tubercles on either side, the absence of the two truncated elytral carinae, the sides of the pronotum with teeth, short temples and a larger body size. 相似文献

The scorpionfly family Holcorpidae (Mecoptera) has been informally discussed since the early 1960’s, but a detailed treatment in accordance with the provisions of the International Code of Zoological Nomenclature for naming families was not provided until Willmann did so in 1989; he is recognized as author of the family. The Holcorpidae concept is revised here based on examination of its two specimens of Holcorpa maculosa from the Late Eocene of Florissant, Colorado, and a third, new specimen from the Early Eocene Okanagan Highlands locality at McAbee, British Columbia, Canada. This new specimen belongs to a second, new species, which is described here, Holcorpa dillhoffi n. sp. 相似文献
