Zoraptera is one of the smallest and least known insect orders, with only 47 described species, mostly known from tropical regions. Data on their distribution remain largely scattered throughout the extensive and often old and/or not easily accessible literature. Recent changes in the supraspecific classification of the order, combined with recent discoveries of new species and other taxonomic changes, have made the understanding of the distribution of Zoraptera even less clear. To summarize and update the knowledge of the worldwide distribution of Zoraptera, we have compiled a data resource of occurrence records: Zoraptera Occurrence Dataset. The dataset contains up-to-date information on the distribution of all zorapteran species according to the latest classification. The dataset is regularly curated and updated with new records from the literature and revised records from iNaturalist and GBIF.

Zoraptera (also called "angel insects") is one of the most unexplored insect orders. However, it holds promise for understanding the evolution of insect karyotypes and genome organization given its status as an early branching group of Polyneoptera and Pterygota (winged insects) during the Paleozoic. Here, we provide karyotype descriptions of three Zorapteran species: Brazilozoros huxleyi (2n♂; ♀ = 42; 42), B. kukalovae (2n♂; ♀ = 43; 44) and Latinozoros cacaoensis (2n♂; ♀ = 36; 36). These species represent two of the four recently recognized Zorapteran subfamilies. Contrary to an earlier suggestion that Zoraptera has holocentric chromosomes, we found karyotypes that were always monocentric. Interestingly, we detected both X0 (B. kukalovae) and XY (B. huxleyi, L. cacaoensis) sex chromosome systems. In addition to conventional karyotype descriptions, we applied fluorescent in situ hybridization for the first time in Zoraptera to map karyotype distributions of 18S rDNA, histone H3 genes, telomeres and (CAG)n and (GATA)n microsatellites. This study provides a foundation for cytogenetic research in Zoraptera.
