Abstract We describe the first bioinclusion found in a new Cretaceous amber outcrop, called La Rodada, in the Province of Asturias (North of Spain). It represents the first fossil record of the genus Epieremulus Berlese, 1916 (Acariformes, Oribatida, Caleremaeidae). A new species, Epieremulus sidorchukae, is described and a comparison with extant species of the genus Epieremulus and notes on their biogeography are provided.

Abstract Three larval neuropterans (Insecta: Neuropterida) with straight mandibulomaxillary stylets are described from Lower Cretaceous (late Albian, ~105 Ma) Spanish amber: a third-instar beaded lacewing (Berothidae) from the Penacerrada I locality (Burgos, Spain), and two specimens from the San Just locality (Teruel, Spain), i.e., a tentative first-instar beaded lacewing and a remarkable specimen considered a berothid-like mantispoid or dilaroid (instar unknown) displaying a combination of pot...

A new fossil genus of the family Hybotidae is described, based on male and female specimens. The new genus is monotypic: Syneproctus caridadi gen. et sp. nov. It belongs to the subfamily Hybotinae and shares some characters with the extant genera Syneches Walker, 1852, Stenoproctus Loew, 1858 and Chillcottomyia Saigusa, 1986; however, the differences, principally in the wing venation (shortened cua cell, horizontal m-cu crossvein) and sclerotized mouthparts, support the description of a new genu...

Abstract Two virtually complete termites in Lower Cretaceous amber from the Penacerrada I outcrop, Spain, are described and figured, representing the most well-preserved Isoptera yet discovered from the Albian stage. The material is described as Ithytermes montoyai gen. et sp. nov., and is similar in many details to the slightly younger Krishnatermes yoddha Engel, Barden, and Grimaldi from northern Myanmar amber. Given the presence of distinct soldiers in this grade of Cretaceous termites, it is...

Multiple predatory insect lineages have developed a raptorial lifestyle by which they strike and hold prey using modified forelegs armed with spine-like structures and other integumentary specialisations. However, how structures enabling the raptorial function evolved in insects remains largely hypothetical or inferred through phylogeny due to the rarity of meaningful fossils. This is particularly true for mantidflies (Neuroptera: Mantispidae), which have a scarce fossil record mostly based on r...

Ancient protein analysis is a rapidly developing field of research. Proteins ranging in age from the Quaternary to Jurassic are being used to answer questions about phylogeny, evolution, and extinction. However, these analyses are sometimes contentious, and focus primarily on large vertebrates in sedimentary fossilisation environments; there are few studies of protein preservation in fossils in amber. Here we show exceptionally slow racemisation rates during thermal degradation experiments of re...

Angiosperms and their insect pollinators form a foundational symbiosis, evidence for which from the Cretaceous is mostly indirect, based on fossils of insect taxa that today are anthophilous, and of fossil insects and flowers that have apparent anthophilous and entomophilous specializations, respectively. We present exceptional direct evidence preserved in mid-Cretaceous Burmese amber, 100 mya, for feeding on pollen in the eudicot genus Tricolporoidites by a basal new aculeate wasp, Prosphex ant...
