BackgroundAn extinct new family of Pentatomomorpha, Venicoridae Yao, Ren & Cai fam. nov., with 2 new genera and 2 new species (Venicoris solaris Yao, Ren & Rider gen. & sp. nov. and Clavaticoris zhengi Yao, Ren & Cai gen. & sp. nov.) are described from the Early Cretaceous Yixian Formation in Northeast China.Methodology/Principal FindingsA cladistic analysis based on a combination of fossil and extant morphological characters clarified the phylogenetic status of the new family and has allowed the reconstruction of intersuperfamily and interfamily relationships within the Infraorder Pentatomomorpha. The fossil record and diversity of Pentatomomorpha during the Mesozoic is discussed.Conclusions/SignificancePentatomomorpha is a monophyletic group; Aradoidea and the Trichophora are sister groups; these fossils belong to new family, treated as the sister group of remainder of Trichophora; Pentatomoidea is a monophyletic group; Piesmatidae should be separated as a superfamily, Piesmatoidea. Origin time of Pentatomomorpha should be tracked back to the Middle or Early Triassic.
Multimodal named entity recognition and relation extraction (MNER and MRE) is a fundamental and crucial branch in information extraction. However, existing approaches for MNER and MRE usually suffer from error sensitivity when irrelevant object images incorporated in texts. To deal with these issues, we propose a novel Hierarchical Visual Prefix fusion NeTwork (HVPNeT) for visual-enhanced entity and relation extraction, aiming to achieve more effective and robust performance. Specifically, we regard visual representation as pluggable visual prefix to guide the textual representation for error insensitive forecasting decision. We further propose a dynamic gated aggregation strategy to achieve hierarchical multiscaled visual features as visual prefix for fusion. Extensive experiments on three benchmark datasets demonstrate the effectiveness of our method, and achieve state-of-the-art performance 1 .
An extinct new family of flower bugs, Vetanthocoridae fam. nov., with 2 new tribes, Vetanthocorini and Crassicerini, 8 new genera, and 9 new species (Byssoidecerus levigatus gen. & sp. nov., Collivetanthocoris rapax gen. & sp. nov., Vetanthocoris decorus gen. & sp. nov., Vetanthocoris longispicus gen. & sp. nov., Curvicaudus ciliatus gen. & sp. nov., Mecopodus xanthos gen. & sp. nov., Pustulithoracalis gloriosus gen. & sp. nov., Curticerus venustus gen. & sp. nov., and Crassicerus furtivus gen. & sp. nov.) are described from the Late Jurassic Yixian Formation in western Liaoning Province, China. These fossil records suggest there was an important diversity of flower bugs in the earlier Late Jurassic of northern China. A key to four flower-bug families and a key to the known fossil flower bugs are provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
