Abstract Calonecrinae represent a unique but small subfamily of Nitidulidae that is endemic to South Asia. Their habitats, the Asian lowland forests, are under imminent threat degradation, posing risk rapid extinction for these species in their specific locales. Despite looming existence, our understanding this enigmatic group remains limited. We conducted an examination museum and newly collected specimens, alongside review literature, which led discovery new species, Calonecrus mindanaoensis sp. nov ., from Mindanao, Philippines. Additionally, we provide detailed illustrations various type specimens genus Thomson. For first time, immature stages were described based on jendeki , with photographs including scanning electron microscopy images. natural history was uncovered, revealing all life uniquely adapted complete entire cycle sticky sap. reevaluate phylogenetic placement analyses mitochondrial genomes. positioned within Epuraeinae clade phylogenetically related epuraeine Trimenus . Consequently, study proposes reclassifying as Calonecrini stat. extremely modified tribe Epuraeinae. This research significantly broadens ecology Calonecrini. Along taxonomic results, solid foundation conservation further into habitat preferences evolutionary behaviour.

An unusual Cretaceous beetle with affinity to Anamorphidae (Coleoptera: Coccinelloidea)

PeerJ, Journal Year: 2024, Volume and Issue: 12, P. e18008 - e18008

Published: Sept. 16, 2024

Coccinelloid beetles have a sparse fossil record in the Mesozoic. Here, we describe and illustrate an unusual coccinelloid beetle, Yassibum yoshitomii gen. et sp. nov., from mid-Cretaceous Kachin amber. stands out within Coccinelloidea due to its notched profemora presence of antennal grooves on elytral epipleura. Based our phylogenetic analyses, suggest that is most likely related family Anamorphidae. The alternative placements are critically evaluated based comparison morphology.

Detection of Hindwing Landmarks Using Transfer Learning and High-Resolution Networks

Biology, Journal Year: 2023, Volume and Issue: 12(7), P. 1006 - 1006

Published: July 14, 2023

Hindwing venation is one of the most important morphological features for functional and evolutionary analysis beetles, as it key used beetle flight performance design beetle-like flapping wing micro aerial vehicles. However, manual landmark annotation hindwing a time-consuming process hindering development morphology research. In this paper, we present novel approach detection landmarks on hindwings leaf beetles (Coleoptera, Chrysomelidae) using limited number samples. The proposed method entails transfer pre-existing model, trained large natural image dataset, to specific domain hindwings. This achieved by deep high-resolution network backbone. low-stage parameters are frozen, while high-stage re-trained construct model. A dataset was constructed, varying numbers randomly selected results demonstrate that average normalized mean error (100 samples) remains below 0.02 only reached 0.045 when mere three samples training. Comparative analyses reveal out-performs prevalently (i.e., residual network). study showcases practicability employing images-specifically, those in ImageNet-for purpose pre-training models particular, providing promising insect digitization.
