Article Synopsis
- This text presents a detailed catalogue of stick and leaf insect type specimens housed at the Zoological Museum Hamburg, totaling 305 specimens from 130 species.
- The catalogue includes various types, such as holotypes, lectotypes, and paratypes, with a focus on contributions from notable researchers like Redtenbacher and Zompro.
- The updated information will serve as a crucial resource for future research and taxonomy of the Phasmatodea group.
Article Synopsis
- * Using double-digest RAD sequencing (ddRADseq), the research reconstructs the evolutionary relationships among Central European grasshopper species, revealing significant discordance with mitochondrial DNA barcoding.
- * The findings support reclassifications of certain species, enhance understanding of species distinctiveness, and illustrate the effectiveness of high-throughput genomic methods in clarifying complex evolutionary histories in orthopteran groups.
Habitat destruction and fragmentation are among the major current threats to global biodiversity. Fragmentation may also affect species with good dispersal abilities. We study the heath bushcricket , a specialist of steppe-like habitats across Europe that are highly fragmented, investigating if these isolated populations can be distinguished using population genomics and if there are any traces of admixture or dispersal among them.

- - The genus Lygodactylus, consisting of 79 species primarily found in Sub-Saharan Africa and Madagascar, has a rich evolutionary history, likely originating in Madagascar and undergoing multiple transoceanic dispersal events.
- - Recent studies focused on L. grotei pakenhami from Pemba Island, L. insularis from Juan de Nova, and L. verticillatus from Europa Island to determine their taxonomic status and origins in relation to other species in the L. capensis and L. verticillatus groups.
- - Genetic analysis revealed that L. grotei pakenhami is distinct from its African counterparts, leading to its elevation to a separate species, Lygod
Animal genomes vary widely in size, and much of their architecture and content remains poorly understood. Even among related groups, such as orders of insects, genomes may vary in size by orders of magnitude-for reasons unknown. The largest known insect genomes were repeatedly found in Orthoptera, e.
