A Probable Pollination Mode Before Angiosperms: Eurasian, Long-Proboscid Scorpionflies

Science (2009)

Dong Ren Conrad C. Labandeira Jorge A. Santiago‐Blay Alexandr P. Rasnitsyn Chungkun Shih

The head and mouthpart structures of 11 species of Eurasian scorpionflies represent three extinct and closely related families during a 62-million-year interval from the late Middle Jurassic to the late Early Cretaceous. These taxa had elongate, siphonate (tubular) proboscides and fed on ovular secretions of extinct gymnosperms. Five potential ovulate host-plant taxa co-occur with these insects: a seed fern, conifer, ginkgoopsid, pentoxylalean, and gnetalean. The presence of scorpionfly taxa suggests that siphonate proboscides fed on gymnosperm pollination drops and likely engaged in pollination mutualisms with gymnosperms during the mid-Mesozoic, long before the similar and independent coevolution of nectar-feeding flies, moths, and beetles on angiosperms. All three scorpionfly families became extinct during the later Early Cretaceous, coincident with global gymnosperm-to-angiosperm turnover.

First non‐amber Mesozoic pseudoscorpion from Upper Triassic deposits of eastern Europe, with a description of two new fossil subfamilies (Arachnida, Pseudoscorpiones, Feaellidae)

Papers in Palaeontology (2022)

Vasiliy B. Kolesnikov И. С. Турбанов K. Yu. Eskov Evgenia A. Propistsova A. S. Bashkuev

Abstract Pseudoscorpiones is one of the oldest arachnid orders, known in the palaeontological record since the Middle Devonian ( c . 390 Ma). The following reliable indications of fossil pseudoscorpions occur in Early Cretaceous amber: Lebanese amber ( c . 135–125 Ma), Spanish Álava amber ( c . 113–100 Ma), Archingeay amber ( c . 100 Ma) and Burmese amber ( c . 99 Ma). Thus, there is a gap of at least 255–265 myr in the palaeontological record of pseudoscorpions. Therefore, the fossil feaellid pseudoscorpion Archaeofeaella henderickxi gen. et sp. nov., described herein from Triassic deposits of Ukraine ( c . 227 Ma) is of exceptional interest. Based on the analysis of previously unknown morphological features for the family Feaellidae, we place A . henderickxi in Archaeofeaellinae subfam. nov. The previously described species Protofeaella peetersae from Burmese amber is placed in Protofeaellinae subfam. nov., based on comparisons with A . henderickxi as more ancient and closer to the basal group, as well with Recent representatives of this family. Based on this new data, we show that the family Feaellidae survived the Triassic break‐up of Pangaea, and its earliest find is associated not with Gondwana, but with Laurasia; thus, the current ‘Gondwanan distribution’ of the family on the continents of the southern hemisphere is a relic of a wider (probably pancontinental) distribution.

New Jurassic Hangingflies (Insecta: Mecoptera: Bittacidae) from Inner Mongolia, China

Zootaxa (2016)

Sulin Liu Chungkun Shih A. S. Bashkuev Dong Ren

A new bittacid genus, Composibittacus gen. nov., with two new species, C. bipunctatus gen. et sp. nov. and C. reticulatus sp. nov., and a new species of Orthobittacus Willmann 1989, O. maculosus sp. nov., are described from the latest Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China. Composibittacus gen. nov. has unique wing characters, such as five pterostigmal crossveins between R1 and R2 and R1 and R2+3 and an elongated pterostigma area, which distinguishes it from all other known genera in Bittacidae. Orthobittacus maculosus sp. nov. differs from other species of Orthobittacus by a combination of the following wing characters: M with six branches in forewings and hind wings, two crossveins between C and Sc, and two pterostigmal crossveins in the forewing. In addition, O. maculosus sp. nov. has light-colored or white spots on the fore- and hind wings. These new venational characters of Composibittacus gen. nov. and O. maculosus sp. nov. enhance our understanding of the diverse morphological characters of early hangingflies. Furthermore, based on the striking similarity of the wings of O. maculosus sp. nov. and Juracimbrophlebia ginkgofolia Wang, Labandeira, Shih & Ren 2012 (Cimbrophlebiidae), we propose that leaf mimesis and mutualism with ginkgo plants might have been present in the Bittacidae, as has been proposed in the Cimbrophlebiidae.
