The analysis of recently collected specimens from Serra da Neve Inselberg, an isolated mountain located in northern Namibe Province, revealed unexpected taxonomic diversity in the group. Using an integrative taxonomy approach based on morphological and DNA sequence data, with both mitochondrial (16S) and nuclear (RAG-1) genes, we were able to distinguish two distinct populations, described here as two new species, Panaspis ericaesp. nov. and P. mundavambosp. nov. Both species are assumed to be endemic to the inselberg. This reinforces our notion of southwestern Angola as a hotspot of skink diversity, and highlights the urgent need for the conservation of Serra da Neve.","PeriodicalId":36314,"journal":{"name":"Evolutionary Systematics","volume":"17 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141806698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the meantime some 17 authors reported the possibility that the animal should be regarded as a new species. Hitherto overlooked, the German writer Friedrich Justin Bertuch used a new name in the caption to a reproduction of Bell’s plate, as Rhinoceros bicornis Sumatricus. This was published in 1805 in a second edition of his “Bilderbuch für Kinder”, a serial magazine aimed at young people. This work has an extremely complex bibliography through many re-issues and translations, which is only partly resolved. The same name in the combination Rhinoceros Sumatricus was included by Gottlieb Tobias Wilhelm in a companion to the “Bilderbuch” available in 1808. The complicated circumstances of Bertuch’s proposal in 1805 and his unusual usage of a trinomen lead to the suggestion that his book might not be consistently binominal, making the name unavailable. The naming by Wilhelm in 1808 is straightforward and correct, hence Rhinoceros sumatricus Wilhelm, 1808 is an available name and a senior objective synonym of Rhinoceros sumatrensis G. Fischer, 1814. The International Code of Zoological Nomenclature allows the suggestion that Wilhelm’s name was a nomen oblitum (forgotten name). The various plates of the rhinoceros found in the “Bilderbuch” by Bertuch and the “Unterhaltungen aus der Naturgeschichte” are figured and explained.","PeriodicalId":36314,"journal":{"name":"Evolutionary Systematics","volume":"13 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141661008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The biodiversity hotspot Cape Floristic Region of South Africa harbors many endemic and yet undescribed insect species, inter alia, Orthoptera. In this study, extended depth of field and 3D imagery enabled for a novel assessment of the external morphological characteristics used for defining and describing the genetically highly diverse genus Betiscoides Sjösdtedt, 1924, leading to a new definition of the genus’ characteristics as well as a revision of character traits of the known species. Two new species are described and a key to all five recognized Betiscoides species is provided. Application standards are derived to enable replicable and reliable image acquisition and measuring. These findings shall contribute to promote efforts being made to establish image based taxonomic identification for researchers worldwide. High-resolution images provide the basis to train deep learning algorithms/ tools, to detect the smallest differences in highly morphologically alike species, and to implement this knowledge in global species monitoring and conservation action to prevent further species loss.","PeriodicalId":36314,"journal":{"name":"Evolutionary Systematics","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140383865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
