The First Reconstruction of the Head Anatomy of a Cretaceous Insect, †Gerontoformica gracilis (Hymenoptera: Formicidae), and the Early Evolution of Ants
Adrian Richter and others
The fossil record allows a unique glimpse into the evolutionary history of organisms living on Earth today. We discovered a specimen of the stem group ant † Gerontoformica gracilis ( Barden and Grimaldi, 2014 ) in Kachin amber with near-complete preservation of internal head structures, which we document employing ...
UCE phylogenomics, biogeography, and classification of long-horned bees (Hymenoptera: Apidae: Eucerini), with insights on using specimens with extremely degraded DNA
Felipe V Freitas and others
Long-horned bees (Apidae, Eucerini) are found in different biomes worldwide and include some important crop pollinators. In the Western Hemisphere, Eucerini received extensive taxonomic study during the twentieth century, resulting in several revisions of its genera. In contrast, progress on eucerine phylogenetic research ...
Lessons From a Museum's Cabinet: DNA Barcoding and Collections-Based Life Stage Associations Reveals a Hidden Diversity in the Puerto Rican Bank Paedomorphic Lycidae (Coleoptera: Elateroidea: Leptolycini)
Vinicius S Ferreira and Michael A Ivie
The Leptolycini are a group of Lycidae endemic to the West Indies. Leptolycini adult females have been hypothesized to be extreme paedomorphic (i.e., larviform), however, females and larvae of the group are currently unknown. Here we provide the first association of adult male and immature life stages from the Puerto Rico ...
Estimating the Drivers of Diversification of Stoneflies Through Time and the Limits of Their Fossil Record
Corentin Jouault and others
Deciphering the timing of lineage diversification and extinction has greatly benefited in the last decade from methodological developments in fossil-based analyses. If these advances are increasingly used to study the past dynamics of vertebrates, other taxa such as insects remain relatively neglected. Our understanding of ...
Morphology-based Phylogenetic Analysis of Membracoidea (Hemiptera: Cicadomorpha) With Placement of Fossil Taxa and Description of a New Subfamily
Christopher H Dietrich and others
Recently discovered amber-preserved fossil Cicadellidae exhibit combinations of morphological traits not observed in the modern fauna and have the potential to shed new light on the evolution of this highly diverse family. To place the fossils explicitly within a phylogenetic context, representatives of five extinct genera ...
New Non-native Pseudocryptic Cyclorhipidion Species (Coleoptera: Curculionidae: Scolytinae: Xyleborini) Found in the United States as Revealed in a Multigene Phylogeny
Sarah M Smith and Anthony I Cognato
Pseudocryptic species, those that are difficult to diagnose using traditional taxonomic methods, are serious impediments for recognizing the introduction of non-native species. Rapid identification of species facilitates a rapid response to newly introduced species which can lessen their damaging effects. This situation is ...
Molecular Phylogeny of Dermestidae (Coleoptera) Reveals the Polyphyletic Nature of Trogoderma Latreille and the Taxonomic Placement of the Khapra Beetle Trogoderma granarium Everts
Yu-Lingzi Zhou and others
The hide, larder, and carpet beetles (Coleoptera: Dermestidae) are a family of mainly scavenger beetles, with numerous species such as the khapra beetle ( Trogoderma granarium Everts, 1898), the black carpet beetle [ Attagenus unicolor (Brahm, 1791)] and the hide beetle ( Dermestes maculatus De Geer, 1774) being widely ...

Taxonomy in the digital era: ZooBank allows the registration of unavailable taxonomic works
Ladislav Bocak and others
Insect Systematics and Diversity, Volume 9, Issue 2, March 2025, 5, https://doi.org/10.1093/isd/ixaf004
We hope this commentary helps increase the community’s awareness when publishing new names and preparing taxonomic revisions. Some names might become available if subsequent authors fulfill all requirements ( ICZN 1999 ), and multiple usages of the same name in various publications and with ...
Species delimitation and biogeography of Adelgidae (Hemiptera): phylogeographic origin of newly discovered Adelges in Taiwan and their North American sister
Ming-Hsun Chou and others
Insect Systematics and Diversity, Volume 9, Issue 2, March 2025, 4, https://doi.org/10.1093/isd/ixaf008
Phylogeographic analyses provide valuable insights for species delimitation and taxonomic decision-making. The family Adelgidae (infraorder: Aphidomorpha) exhibits relatively low species diversity, comprising approximately 63 species primarily distributed across temperate regions. However, the ...
Mitochondrial gene rearrangements suggest a new genus Paduniellodes (Trichoptera: Psychomyiidae)
Lang Peng and others
Insect Systematics and Diversity, Volume 9, Issue 2, March 2025, ixaf009, https://doi.org/10.1093/isd/ixaf009
The Paduniella andamanensis species group (“ andamanensis ” group) is notable for its morphological consistency and contains the only species in the family Psychomyiidae with markings recorded on its wings, Paduniella fasciaria Peng & Sun, 2024. To elucidate the phylogenetic status of “ ...
Are scientific policies promoting internationalization related with a decline in descriptive taxonomy? Insights from the case of Spanish entomology
Fernando Cortés-Fossati and others
Insect Systematics and Diversity, Volume 9, Issue 2, March 2025, 2, https://doi.org/10.1093/isd/ixaf007
Linnean and Wallacean shortfalls limit our ability to, respectively, describe species and map their distributions. In entomology, well-established national scientific communities are essential for bridging these shortfalls, given the world’s entomofauna crisis. However, descriptive taxonomic ...
Phylogeny, divergence times, and biogeography of the subfamily Tagiadinae (Lepidoptera: Hesperiidae) based on molecular data and morphological characters
Xiangyu Hao and others
Insect Systematics and Diversity, Volume 9, Issue 2, March 2025, 1, https://doi.org/10.1093/isd/ixaf002
The skipper subfamily Tagiadinae has been a key group in taxonomic debates and phylogenetic inconsistencies due to limited taxon sampling and morphological evidence. In this study, we aimed to resolve intra-subfamilial relationships within Tagiadinae using 3 datasets: (i) a molecular dataset (3 ...
Crane fly (Diptera: Tipuloidea) systematics: past, present, and future
Matthew Petersen and others
Insect Systematics and Diversity, Volume 9, Issue 1, January 2025, 5, https://doi.org/10.1093/isd/ixaf005
Superfamily Tipuloidea, commonly known as true crane flies, represents a taxonomically and ecologically diverse group within Diptera. Species in this clade are easily recognized by their characteristic long-legged appearance and are widespread across terrestrial and aquatic habitats. This review ...
Population structure varies among 4 western North American bumble bee species

Insect Systematics and Diversity, Volume 9, Issue 1, January 2025, 4, https://doi.org/10.1093/isd/ixaf003
Bumble bees (Hymenoptera: Apidae, Bombus Latreille, 1802) are critical pollinators—providing the necessary ecological services for food and crop production. In western North America, species-rich bumble bee communities inhabit mountain ranges. However, as climate change increases temperatures, ...
