Abstract
Abstract In the course of evolution, mutualism between pollinators and plants was likely first developed between insects and gymnosperms, since the occurrence of long-proboscid Mecoptera, Neuroptera and Diptera predates the diversification of flowering plants in the Early Cretaceous by at least 60 million years. Here we report one of the most advanced pre-angiosperm pollinator, the Late Jurassic acrocerid fly Archocyrtus kovalevi (Nartshuk, 1996). Re-examination of the holotype specimen has shown that A. kovalevi had an extremely long siphonate proboscis (12 mm) almost twice the length of its body. Relatively, this kind of mouthpart was the longest of all long-proboscid Mesozoic insects hitherto. While long-proboscid species of extant Acroceridae are known as pollinators of long-tubular flowers with long corolla tubes, we hypothesize that A. kovalevi pollinated bisexual bennettitalean cones such as Williamsoniella karataviensis Tur.-Ket., 1963 from the same deposits.

The majority of the analyses of the evolutionary history of the megadiverse class Insecta are based on the documented taxonomic palaeobiodiversity. A different approach, poorly investigated, is to focus on morphological disparity, linked to changes in the organisms’ functioning. Here we establish a hierarchy of the great geological epochs based on a new method using Wagner parsimony and a ‘presence/absence of a morphological type of mouthpart of Hexapoda’ dataset. We showed the absence of major ...

For more than 20 years an undescribed species of Prosoeca has been referred to in numerous publications by pollination biologists, evolutionary biologists and ecologists, originally as being part of the Prosoeca peringueyi Lichtwardt, 1920, pollination guild. Ongoing research in these and related fields has necessitated the formal description of this large-bodied, striking new species, with a proboscis 1.5–2.3 x body length (mean proboscis length ± SD 36.25 ± 3.90 mm). Prosoeca marinusi Barraclo...

Two new genera and species, and one indeterminate genera and species of fossil Mantispidae, Mesomantispinae are described from the Upper Jurassic of Karatau, Kazakhstan: Longicollum benmaddoxi gen. et sp. nov., Ovalofemora abbottae gen. et sp. nov., and Mesomantispinae sp. et gen. indet. Karataumantispa monstruosa is removed from the genus Karataumantispa and placed in the new genus Ovalofemora gen. nov. due to its different foreleg morphology (stout coxae, trochanter, and oval shaped femur), in...

Spider flies are a remarkable lineage of Diptera that develop exclusively as endoparasitoids of spiders; the only exception is found in the Chilean genus Carvalhoa (= Sphaerops), which remains ectoparasitic on the host for weeks after leaving its body. The group is relatively well represented in the fossil record, with some species being quite common in Baltic and Dominican amber deposits. Here we present the first comprehensive review of fossil spider flies (Diptera: Acroceridae), with morpholo...

Summary During the mid-Cretaceous, angiosperms diversified from several nondiverse lineages to their current global domination [1], replacing earlier gymnosperm lineages [2]. Several hypotheses explain this extensive radiation [3], one of which involves proliferation of insect pollinator associations in the transition from gymnosperm to angiosperm dominance. However, most evidence supports gymnosperm–insect pollinator associations, buttressed by direct evidence of pollen on insect bodies, curren...

Molecular dating has suggested that angiosperms existed earlier than the Late Cretaceous. Scattered fossil evidence for Triassic or Jurassic angiosperms exists but this Review concludes that the case remains unproven at best.

Summary 1.Proboscis length has been proposed as a key dimension of plant pollination niches, but this niche space has not previously been explored at regional and global scales for any pollination system. Hawkmoths are ideal organisms for exploring pollinator niches as they are important pollinators in most of the biodiverse regions of the earth and vary greatly in proboscis length, with some species having the longest proboscides of all insects. 2.Using datasets for nine biogeographical regions...

Abstract Although recent molecular phylogenetic analyses suggest a great antiquity, going into the Jurassic, for the small modern fly family Hilarimorphidae, no fossil was attributed to this group. The first fossil hilarimorphid Cretahilarimorpha lebanensis gen. et sp. nov., is described, based on a specimen from the Lower Cretaceous Lebanese amber. Its external morphology is analysed and compared with that of Hilarimorpha , unique modern hilarimorphid genus. The differences concern the wing ven...

Mid-Mesozoic kalligrammatid lacewings (Neuroptera) entered the fossil record 165 million years ago (Ma) and disappeared 45 Ma later. Extant papilionoid butterflies (Lepidoptera) probably originated 80–70 Ma, long after kalligrammatids became extinct. Although poor preservation of kalligrammatid fossils previously prevented their detailed morphological and ecological characterization, we examine new, well-preserved, kalligrammatid fossils from Middle Jurassic and Early Cretaceous sites in northea...

Morphological insect-insect mimicry is known from few Cretaceous cockroaches and a beetle. Formicamendax vrsanskyi gen. et sp. n. (Blattaria, Alienopteridae) shows myrmecomorph features such as an elongated, smooth and black body, simple fenestrated hindwing, legs lacking protective spines. Elbowed or “geniculate “antenna is a typical character of advanced ants and weevils used for different forms of communication. Together with reduced mouthparts and specialized palps still preserved grasping f...
