Filling knowledge gaps in insect conservation by leveraging genetic data from public archives
Full text linkInsect decline has become a growing concern in recent years, with studies showing alarming declines in populations of several taxa. Our knowledge about genetic spatial patterns and evolutionary history of insects still exhibits significant gaps hindering our ability to effectively conserve and manage insect populations and species. Genetic data may provide valuable insights into the diversity and the evolutionary relationships of insects' species and populations. Public repositories, such as GenBank and BOLD, containing vast archives of genetic data with associated metadata, offer an irreplaceable resource for researchers contributing to our understanding of species diversity, population structure and evolutionary relationships. However, there are some issues in using these data, as they are often scattered and may lack accuracy due to inconsistent sampling protocols and incomplete information. In this paper we describe a curated georeferenced database of genetic data collected in GenBank and BOLD, for insects listed in the International Union for Conservation of Nature (IUCN) Italian Red Lists (dragonflies, bees, saproxylic beetles and butterflies). After querying these repositories, we performed quality control and data standardization steps. We created a dataset containing approximately 33 000 mitochondrial sequences and associated metadata about taxonomy, collection localities, geographic coordinates and IUCN Red List status for 1466 species across the four insect lists. We describe the current state of geographical metadata in queried repositories for species listed under different conservation status in the Italian Red Lists to quantify data gaps posing barriers to prioritization of conservation actions. Our curated dataset is available for data repurposing and analysis, enabling researchers to conduct comparative studies. We emphasize the importance of filling knowledge gaps in insect diversity and distribution and highlight the potential of this dataset for promoting other research fields like phylogeography, macrogenetics and conservation strategies. Our database can be downloaded through the Zenodo repository in SQL format.Database URL: https://zenodo.org/records/837518

No full textSystematic study of the genus Rossimyiops Mesnil (Diptera: Tachinidae)
No full textThe systematic position and generic limits of Rossimyiops Mesnil, 1953 (type species: R. whiteheadi Mesnil, 1953) are critically redefined. Examination of the male terminalia allowed us to demonstrate the unjustified placement of Rossimyiops within the subfamily Dexiinae, tribe Dufouriini and its probable affiliation with the subfamily Tachininae, tribe Minthoini. The following generic names are synonymised with Rossimyiops Mesnil, 1953: Mesnilomyia Kugler, 1972 (type species: M. magnifica Kugler, 1972) syn. nov., and Persedea Richter, 2001 (type species: P. exquisita Richter, 2001) syn. nov. The following new combinations are proposed: Rossimyiops achilleae (Kugler, 1972) comb. nov., R. exquisitus (Richter, 2001) comb. nov., R. longicornis (Kugler, 1972) comb. nov., R. magnificus (Kugler, 1972) comb. nov., and R. subapertus (Herting, 1983) comb. nov. Mesnilomyia rufipes Zeegers, 2007 is established as a synonym of Persedea exquisita Richter, 2001, syn. nov. Rossimyiops austrinus Cerretti sp. nov. from Namibia and Rossimyiops djerbaensis Cerretti sp. nov. from Tunisia are described, illustrated and compared with the other known species of the genus. Male terminalia and female external morphology of R. subapertus and R. whiteheadi are described for the first time. Finally, Mesnilomyia calyptrata Zeegers, 2007 is removed from this genus and placed as Tachinidae incertae sedis
The South African Meligethes of the M. amplicollis-complex (Coleoptera : Nitidulidae : Meligethinae)
No full textThe known South African species of the M. amplicollis-complex in the genus Meligethes Stephens, 1830, are listed and revised. A diagnosis of this species-complex is given, and five species, known to occur in the Western and Eastern Cape Provinces, and southern KwaZulu-Natal, are described or re-described and illustrated. A new sibling species, M. aspalathi sp. n. is described from the southeastern Western Cape Province. Meligethes chevrolati Reitter, 1872, previously erroneously considered a synonym of M. amplicollis Boheman, 1851, is resurrected to specific rank. Meligethes imbricatus Easton, 1953, erroneously attributed to Australia, where Meligethes species are absent, is considered to be a synonym of M. chevrolati Reitter, 1872. Bionomical and ecological data on the species covered, which all use flowers of Fabaceae of the genus Aspalathus as larval host-plants, are also included
