Two new kateretid beetle species (Coleoptera: Kateretidae) with specialized antennal scapes in males from mid-Cretaceous Kachin amber
Kateretidae is a beetle family with 15 reported fossil species, four of them with specialized antennal scape. Specialized scape represents a rare form of sexual dimorphism in Kateretidae. Here we report two new species with a special scape in males of Protokateretes Zhao, Huang and Cai, 2023, and one female individual of an unnamed species of Protokateretes. The discovery of new species provides a supplementary diagnosis of Protokateretes, and increases the biodiversity of the fossil genus. The high diversity of species in Protokateretes provides new insights into sexual dimorphism of Kateretidae in mid-Cretaceous, enriching the knowledge of potential courtship strategy of kateretid beetles in the late Mesozoic.
期刊介绍:
Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings.
Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale.
Research Areas include:
• Regional geology
• Stratigraphy and palaeontology
• Palaeobiology
• Palaeobiogeography
• Palaeoceanography
• Palaeoclimatology
• Evolutionary Palaeoecology
• Geochronology
• Global events.
