Abstract Species spread in a new environment is often associated with founders’ effect, and reduced effective population size genetic diversity. However, diversity does not necessarily translate to low establishment potential. Paracoccus marginatus Williams Granara de Willink polyphagous pest that has invaded 4 continents around 34 years. It was first detected the Northern Territory, Australia July 2023. Following this, we collected 45 specimens from 20 suburbs across 3 regions. Using mitochondrial cytochrome oxidase I nuclear ribosomal RNA genes (18S 28S), examined molecular diagnostics robustness, diversity, haplotype network, demographics (Tajima D) of recently Australian population. We compared our samples publicly available sequences deposited on GenBank. All were suitable for diagnosis 100% identity score. For all genes, found nucleotide negative Tajima D newly P. population, suggesting recent single founder event by few individuals. Comparing study’s global showed Tajima’s D, despite at successfully South America, Africa, Asia, Oceania. Our study highlights role demographic life history traits species’ invasion success. provide baseline dataset detection Australia. Further analysis can insights into invasive adaptation novel environment.

A project initiated in 1991 to untangle species-taxonomy of European Procladius (Chironomidae) has been accomplished. Increasing amount material, loans and especially the development barcodes BIN-system BOLD, made finalization possible after about 33 years. An iterative process based on detailed studies male morphology barcode clusters, BINs, resulted identification 27 species present Europe, most them also Asia (China, Japan, Mongolia Russia) North America (Canada United States). One hundred morphological characters were adopted for which 30 important ones used construct a key an additional helpdesk. The contains three each separation as this is frequently needed reliable identification. ratio GspR, outer length gonostylus versus margin gonostylus, proved be character All but two have BINs. one BIN contained only species. exception that previously was divided into BINs containing morphologically distinct Intraspecific divergence within ranged from 0‒3.3% interspecific 2.0‒8.8%.
