Of these, 997 refer to currently accepted genera, 227 in Dynastinae, 261 in Rutelinae and 509 in Cetoniinae. A further >650 genus-group names are given subgeneric rank or placed in synonymy. The chronology of descriptions of currently valid genera shows similar patterns in each of the three subfamilies with many described in the 1840s, a large group in the late 1800s (especially the Cetoniinae) and early 1900s (Dynastinae and Rutelinae) and a steady increase in numbers following World War 2. We predict that discovery of new genera, as well as the potential for further splitting of mega-genera with elevation of subgenera to full generic level, will continue the upward trend, albeit somewhat balanced by combining the numerous monobasic genera.\u0000 ","PeriodicalId":52569,"journal":{"name":"Megataxa","volume":"7 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141107027","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}

{"title":"Systematics and palaeobiology of kangaroos of the late Cenozoic genus Protemnodon (Marsupialia, Macropodidae)","authors":"Isaac A. R. Kerr, A. Camens, Jacob D. van Zoelen, T. Worthy, G. Prideaux","doi":"10.11646/megataxa.11.1.1","DOIUrl":"https://doi.org/10.11646/megataxa.11.1.1","url":null,"abstract":"Species of the kangaroo genus Protemnodon were common members of late Cenozoic communities across Australia and New Guinea until their extinction in the late Pleistocene. However, since the genus was first raised 150 years ago, it has proven difficult to diagnose, as have the species allocated to it. This is due primarily to the incompleteness of the type material and a heavy reliance on cheek tooth size and slight variations in premolar form. Along with the rare association between cranial and postcranial material, this has hampered understanding of the palaeobiology of these large-bodied kangaroos. Here we review and re-diagnose Protemnodon, recognising a total of seven species and providing a hypothesis of species interrelationships. The following new synonymies are made: Protemnodon chinchillaensis is synonymised with P. otibandus and P. hopei with P. tumbuna. The following are considered nomina dubia: Protemnodon brehus, P. roechus, P. mimas, P. antaeus, and P. devisi. We reveal that the morphology of the cheek dentition is not as consistently useful for differentiating species of Protemnodon as features of the cranium and postcranial skeleton. As a whole, the species share anatomical features that reflect stability and power in the limb joints, yet they differ in body proportions, and axial and limb morphology. This we interpret as showing locomotory adaptations to different habitats. Of the three Pliocene species, Protemnodon snewini is interpreted as a medium- to high-geared hopper, suggesting proficiency in more open environments, whereas P. dawsonae sp. nov. we infer to have been a medium-geared inhabitant of eastern Australian forests and woodlands. Protemnodon otibandus, with a range extending through the woodlands and forests of eastern Australia into the rainforests of eastern New Guinea, displays adaptations to slower hopping. Its Pleistocene descendant, P. tumbuna, is convergent on the morphology of modern New Guinea forest wallabies, and was likely facultatively quadrupedal. Of the three Australian Pleistocene species, the long-necked P. anak is hypothesised to have been a large, medium-geared, eastern Australian species, and P. mamkurra sp. nov. a robust, low-geared resident of well-wooded southern Australia habitats. By contrast, P. viator sp. nov. was larger but more gracile, suggested to be a medium- to high-geared species convergent in some traits on large extant kangaroos. This and a wide inland distribution point to adeptness in open, arid environments. Protemnodon mamkurra sp. nov. and P. viator sp. nov. occupy the morphospace previously occupied by P. roechus and P. brehus. Overall, the species of Protemnodon exhibit a degree of ecomorphological variation suggestive of a broader array of ecological adaptations than hitherto envisioned.","PeriodicalId":52569,"journal":{"name":"Megataxa","volume":"49 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140700367","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}

Megataxa has grown steadily since January 2020 and has published 44 papers of various types in 3329 pages, 14 issues and 10 volumes, averaging 76 pages per paper and including six large monographs. These were contributed by 99 authors from 27 countries in six regions. Analysis of citation data in the Web of Science Core Collection showed that papers in Megataxa were cited three to nine times as often as those in Zootaxa published in the same year. The estimated (non-official) journal impact factor of 2023 for Megataxa is 6.8. These indicate that although Megataxa is still in its infancy, it has great promise to become a journal of high impact in taxonomy.","PeriodicalId":52569,"journal":{"name":"Megataxa","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139145117","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}

Here we discuss how this data contributes to character analysis, species identification, but also to integration with other data sources such as citizen science observations (which depend on correct identifications). Importantly, the data described here may serve as training data for machine learning projects and we present examples of species comparisons using ChatGPT. While these AI-driven comparisons are still erroneous, we expect substantial improvements in the near future. We request the herpetological community to help complete our public collection of species descriptions and suggest that other species databases follow suit and provide similar data for their taxa.","PeriodicalId":52569,"journal":{"name":"Megataxa","volume":"44 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135927773","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}

With reference to a proposal to amend the International Code of Nomenclature for algae, fungi, and plants (Turland et al. 2018), adoption of which would eliminate epithets with the root ca[f]f[e]r- from the scientific nomenclature in use for algae, fungi, and plants (Smith & Figueiredo 2021), Pethiyagoda (2023: 21) further stated that: “They [Hammer & Thiele (2021)] cite, for example, a proposal by Smith & Figueiredo (2021)”. This statement is not correct. Both Hammer & Thiele (2021) and Smith & Figueiredo (2021) were published on “15 December 2021”, and Hammer & Thiele (2021) could not have cited Smith & Figueiredo (2021).

Preregistration is a practice for researchers to document their hypotheses, design and methods of their proposed studies in a public repository before they start the study and collect the data (Nosek et al. 2018). It is believed that preregistration can help reduce bias, increase transparency, and improve study design (especially replicability) of research (e.g. Nosek et al. 2018; Krypotos et al. 2022), including exploratory research such as some aspects of biodiversity discovery and taxonomy (Dirnagl et al. 2020). While preregistration has been already employed in other fields such as social sciences (e.g. Camerer et al. 2016, 2018) and ecology/evolution (e.g. Kelly 2019), it has yet been adopted in taxonomy.

Because of this, there are sometimes multiple viable competing methodological paths, which could lead to different ranking (or even grouping) decisions. As a result, it is often unclear what it means for a group to be recognized as a species, the groups recognized as species are not always comparable, and some have even called ranking decisions ‘subjective’. To mitigate the problems this causes for users of taxonomy and taxonomists, we propose that taxonomists across the tree of life should start preregistering their research design and criteria for species delimitation in advance of their research. We argue that even if it were to require additional effort, preregistering taxonomic research would strongly benefit taxonomy in the long term, by increasing the transparency and usability of taxonomic outcomes and by reducing the need for ad hoc methodological decisions.","PeriodicalId":52569,"journal":{"name":"Megataxa","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79379764","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}
