The generic name is a combination of choní (Greek, meaning ‘funnel’) and idris (Greek, meaning ‘ant’), in reference to the shape of the clypeus. The name is feminine. Diagnosis (gyne). Highly similar to Dhagnathos, but smaller (body length ca. 9 mm), with clypeus triangulate and expanded posteriorly into rounded horn, lateral margins of clypeus raised into serrated carina; propodeum with posterodorsal ridge; ventral margin of petiole with pointed spicule-like process and lamella; gastral segments I and II (abdominal segments III and IV) with conspicuous constriction. Separable from Dhagnathos with clypeal horn, apical portion of mandibles, and flagellomeres distinctly more compact; with inner margin of mandible projecting medioventrally into a large triangular blade that is gradually tapering to the tip of mandible; this blade with ventral corner rounded and dorsomedial margin serrate; in frontal view, when mandibles closed, ventral corners of blades slightly overlapping and medial margins almost parallel, nearly touching, so that labrum and clypeal area ventral to horn are entirely concealed, and mandibles are encased in clypeal triangle.Published as part of Perrichot, Vincent, Wang, Bo & Barden, Phillip, 2020, New remarkable hell ants (Formicidae: Haidomyrmecinae stat. nov.) from mid-Cretaceous amber of northern Myanmar, pp. 1-18 in Cretaceous Research 109 on page 7, DOI: 10.1016/j.cretres.2020.104381, http://zenodo.org/record/365307
Dhagnathos Perrichot & Wang & Barden 2020, gen. nov.
No full textGenus Dhagnathos gen. nov. urn:lsid:zoobank.org:act: 48DA68FC-1DF6-4 A 90-86DA- 4EF527D762 F 4. Type species: Dhagnathos autokrator sp. nov. Etymology. The generic name is a combination of Dha, a singleedged sword with long, gently curved blade common throughout mainland Asia, and often called ‘the national sword of Burma’, and gnathos (Greek, meaning ‘jaw’), in reference to the mandibles' shape. The name is masculine. Diagnosis (gyne). Large, robust ant, body length ca. 14 mm. Clypeus funnel-shaped resulting from extreme posterior expansion, extends well beyond antennal insertions, with lateral margins raised into carinae arising above mandible insertion and converging posteriorly to form a clypeal horn; horn bent forward at right angle from frons, its tip gently rounded, not spatulate, its underside deeply furrowed, forming a channel opening toward the labrum; clypeal carinae, including horn's edges, rimmed by stout, short, tooth-like denticles. Mandibles scythe-like, the elbow between basal and distal portions with a strong (isosceles) triangular blade pointing medially and ventrally, the apical portion long, curved upwards and backwards, acutely tapering to the tip and with dorsal (posterior) margin furrowed and serrated; mandibles widely spaced, approximated only apically, with medioventral blade not overlapping (in frontal view, when closed, with distal portions aligned with frontal carinae so that the labrum and clypeal area below horn are exposed). Labrum coated laterally by a brush of stiff, spine-like setae and long fine setae, dorsal surface sparsely covered by long fine setae, anterior margin glabrous. Antennae elongate, with flagellomeres thin and long. Ocelli and compound eyes large, the latter reniform.Published as part of Perrichot, Vincent, Wang, Bo & Barden, Phillip, 2020, New remarkable hell ants (Formicidae: Haidomyrmecinae stat. nov.) from mid-Cretaceous amber of northern Myanmar, pp. 1-18 in Cretaceous Research 109 on page 4, DOI: 10.1016/j.cretres.2020.104381, http://zenodo.org/record/365307
Paleontological Contributions no. 1: Long-tailed wasps (Hymenoptera: Megalyridae) from Cretaceous and Paleogene European amber
No full textFifty-two fossils of megalyrid wasps from various collections of European amber were examined. A male neotype for Prodinapsis succinalis Brues and a female neotype for P. minor Brues are designated. The two species are redescribed and illustrated from Eocene and Oligocene amber, and males are tentatively distinguished by the length of their forewing. Three new species are described: P. pumilio Perrichot & Perkovsky n. sp., from a single female preserved in upper Eocene Rovno amber (Ukraine); P. janzeni Perrichot n. sp., from three males in Eocene Baltic and Rovno amber; and P. oesiensis Perrichot n. sp., from a single male preserved in lower Eocene French amber. A key for the identification of the five species of Prodinapsis is provided. Megazar elegans Perrichot n. gen. and n. sp., and Megalava truncata Perrichot n. gen. and n. sp., are described from Albian French and Spanish amber, respectively, and are placed in a new tribe Megazarini Perrichot n. tribe, which is characterized by the mesothoracic spiracle not being surrounded by pronotal cuticle posteriorly, the inner margin of the metathoracic trochanter, femur, tibia, and first two tarsomeres having comblike spines or stiff setae, the forewing with M+Cu being tubular, the basal segment of Rs being very long, and a narrow medial cell [1M]. The following new fossil genera and species are also described and illustrated: Ukrainosa prolata Perrichot & Perkovsky n. gen. and n. sp., from Eocene Rovno amber; Rubes bruesi Perrichot n. gen. and n. sp. from Eocene Baltic amber; Megallica parva Perrichot n. gen. and n. sp., from upper Albian amber of France; and Valaa delclosi Perrichot n. gen. and n. sp., from lower Albian amber of Spain. A second specimen of Megalyra baltica Poinar & Shaw is illustrated from Baltic amber and discussed. A key for the identification of all known fossil and extant genera is provided. The new fossils extend significantly our knowledge of the evolutionary history of Megalyridae sensu stricto (i.e., excluding Cleistogastridae) that hitherto comprised eight modern and two extinct genera. They also emphasize the relictual distribution of the family that is now mainly restricted in tropical and austral regions, while it obviously occurred widely in ancient forests of the northern hemisphere during the Mesozoic and Cenozoic era.

gen. et sp. nov. (Deuteromycotina): a Cretaceous predatory fungus
No full textIn habitats where nitro-en is the limiting factor, carnivorous fungi gain an advantage by preying on nematodes and other microorganisms. These fungi are abundant in modern terrestrial ecosystems, but they are not predestined for preservation as fossils. Conclusions on their evolutionary history are therefore mainly based on molecular studies that are generally limited to those taxa that have survived until today. Here we present a fossil dimorphic fungus that was found in Late Albian amber front southwestern France. This fungus possessed unicellular hyphal rings as trapping devices and formed blastospores from which a yeast stage developed. The fossil probably represents an anamorph of an ascomycete and is described as Palaeoanellus dimorphus gen. et sp. nov. Because predatory fungi With regular yeast stages are not known from modern ecosystems, the fungus is assumed to not be related to any Recent carnivorous fungus and to belong to an extinct lineage of carnivorous fungi. The inclusions represent the only record of fossil fungi that developed trapping devices, so far. The fungus lived c. 100 million years ago in a limnetic-terrestrial microhabitat. and it was a part of a highly diverse biocenosis at the forest floor of a Cretaceous coastal amber forest
