A revision of Peltariosilis Wittmer (Coleoptera: Cantharidae), a surprisingly diverse Amazonian radiation

Peltariosilis Wittmer, 1952 is a South American Silinae genus characterised by the highly modified male pronotum and scutellum with a remarkable lamellar projection. Six species were previously recognised. The study of numerous specimens from previously unsampled localities and the revision of previously studied material shows that Peltariosilis is far more diverse than previously recognised. 15 species are here recognised as valid, nine of which are described as new: P. brancuccii, P. brunneoapicalis, P. cleidecostae, P. diversicollis, P. flavicornis, P. gracilicornis, P. major, P. orientalis and P. parviscutellaris spp. nov. A comparative study and new morphological terminologies are introduced for pronotum, scutellum and male genitalia. All Peltariosilis species are described and illustrated, including the first illustration of a female pronotum, and an identification key is provided. A map is given, including records of all known Peltariosilis, showing a distribution confined to the Amazonian subregion (Suriname, French Guiana, N Brazil, E Peru and NE Bolivia). The identity of the type species P. scutulata (Wittmer, 1952), hitherto considered as broadly distributed and highly variable, is addressed through study of their type series and additional specimens from widespread localities

Systematics, bionomy, and metamorphosis of Coleoptera (Insecta): Papers celebrating the 80th birthday of Cleide Costa - Foreword from the editors

We present a brief biography of Dr. Cleide Costa, eminent entomologist from Museu de Zoologia da Universidade de São Paulo (MZUSP). She has been dedicating the last six decades to the study of adults and immatures of Coleoptera. Dr. Costa is the pioneer in collecting and rearing immature beetles in Brazil, being responsible for establishing the most extensive Latin American collection of reared immatures Coleoptera. We discuss central aspects of her personal history, as well as career landmarks and achievements. A compilation of taxa introduced to science by her, taxa named in her honor, and a full list of her scientific, educational and cultural production are provided in chronological order. More than a biographical account, this publication is an acknowledgment of Dr. Cleide Costa’s legacy to entomology

Illustrated catalogue of type specimens of Megalopodidae (Coleoptera) deposited at the Museu de Zoologia da Universidade de São Paulo

The Museu de Zoologia da Universidade de São Paulo (MZUSP) houses an important Megalopodidae collection representing 144 species, especially from Brazil and the Neotropical fauna. The type specimens of some species have never been accessed since their original descriptions, and are thus unknown to a major part of the Megalopodidae researchers. Presented here is an illustrated catalogue of the megalopodid type specimens of 32 species deposited at MZUSP, featuring photos of habitus and labels, and complete label data of all the specimens, which originally belonged to Jacintho Guérin’s personal collection. Conflicting and inconsistent data provided in the literature and in the specimens’ labels are addressed. Taxa originally proposed as species varieties are here reaffirmed as valid, with subspecific rank. Agathomerus varians Monrós, 1945 and Plesioagathomerus vittatus Monrós, 1945, originally described as junior synonyms, are considered unavailable names. The subspecific epithet ngriapex is emended into Agathomerus bifasciatus nigrapex Guérin, 1949. An overview of the MZUSP Megalopodidae collection is presented with a history of the arrival of Guérin’s specimens

The systematics of Dysmorphocerinae (Cantharidae) based on larvae

Dysmorphocerinae is a subfamily of Cantharidae erected for a group of genera with a mainly gondwanan distribution whose adult forms could not be reliably assigned to any other subfamily. The systematic position and monophyly of Dysmorphocerinae remains questionable, as recent molecular and morphological studies have produced conflicting results. Despite the importance of immature morphology for characterising lineages of Cantharidae, so far, the larvae of only two dysmorphocerine species had been briefly described: Neoontelus sp., from New Zealand, and Afronycha picta (Wiedemann), from South Africa. Their morphologies considerably differ from one another, and the larvae cannot be readily attributed to any subfamily, as usually occurs with cantharid larvae. Here, we fully describe for the first time the larvae of Asilis Broun (New Zealand) and Plectonotum laterale Pic (Brazil) and redescribe Neoontelus Wittmer (New Zealand). We also diagnose larvae of Heteromastix Boheman (Australia) and A. picta. Dysmorphocerinae cannot be clearly diagnosed because each genus has a unique combination of features, though Neoontelus is the most divergent. We conclude that the Dysmorphocerinae may not be monophyletic with Plectonotum laterale, Asilis, Neoontelus, Heteromastix showing a closer relationship to Malthininae and Afronycha more aligned with Silinae or Cantharinae. The double gland openings present on the body of Neoontelus reported by are reinterpreted as a complex character involving a single posterior pore linked to a gland and an anterior sensillum that may serve as a trigger for the release of defensive chemicals. These are also reported in Asilis and Heteromastix and may be a potential synapomorphy for part of the Dysmorphocerinae. Neoontelus has a series of unique features, including a cotyliform glandular pore on abdominal segment IX.The São Paulo Research Foundation, The Foundation of Support to the University of São Paulo and Fundação de Amparo e Desenvolvimento da Pesquisa as well as funded in part by Strategic Science Investment Funding for Crown Research Institutes from the Ministry of Business, Innovation and Employment’s Science and Innovation Group.https://brill.com/view/journals/ise/ise-overview.xmlhj2023Zoology and Entomolog

Processos oxidativos avançados: fundamentos e aplicação ambiental

The Advanced Oxidation Processes (or Advanced Processes Oxidation) known by the acronym POA's are processes which rely on the generation of free radicals, especially the hydroxyl radical (∙OH), which has high oxidizing power and can promote the degradation of various compounds pollutants efficiently. These processes have gained great attention due to the increasing complexity and difficulty in treating wastewater, which has been the reason for searching for new methodologies aimed at remediation of such wastes. Therefore, the present study aimed to relate four treatment methodologies of Advanced Oxidation: H2O2 processes involving, systems Fenton and Photo-Fenton, Heterogeneous Photocatalysis and systems based on the use of ozone. The present review describes the main principles of these processes and discusses mechanisms of degradation of organic pollutants. The main advantages of using these processes is in its specificity and can be used to degrade substrates of any chemical nature, the possibility of employment to degrade pollutants whose concentration is very low (μg L-1) and not waste. Furthermore, some drawbacks are noted, such costs can be high and the formation of reaction byproducts. Os Processos Oxidativos Avançados (ou Processos Avançados de Oxidação), conhecidos pela sigla POA’s, são processos que se baseiam na geração de radicais livres, principalmente o radical hidroxil (∙OH), que possui alto poder oxidante e pode promover a degradação de vários compostos poluentes eficientemente. Esses processos têm obtido grande atenção devido ao aumento da complexidade e dificuldade no tratamento de águas residuárias, o que tem sido motivo para a busca de novas metodologias visando a remediação desses rejeitos. Diante disso, o presente trabalho teve por objetivo relacionar quatro metodologias de tratamento via Oxidação Avançada: processos envolvendo H2O2, sistemas Fenton e Foto-Fenton, Fotocatálise Heterogênea e sistemas fundamentados na utilização de ozônio. A revisão realizada descreve os principais fundamentos destes processos e discute mecanismos de degradação de poluentes orgânicos. As principais vantagens da utilização destes processos estão em sua inespecificidade, podendo ser utilizados para degradar substratos de qualquer natureza química, na possibilidade de emprego para degradar poluentes cuja concentração seja muito baixa (μg L-1) e na não geração de resíduos. Por outro lado, algumas desvantagens são observadas, como os custos que podem ser elevados e a formação de subprodutos de reação

CHEX-MATE:Morphological analysis of the sample

In this work, we performed an analysis of the X-ray morphology of the 118 CHEX-MATE (Cluster HEritage project with XMM-Newton - Mass Assembly and Thermodynamics at the Endpoint of structure formation) galaxy clusters, with the aim to provide a classification of their dynamical state. To investigate the link between the X-ray appearance and the dynamical state, we considered four morphological parameters: the surface brightness concentration, the centroid shift, and the second- and third-order power ratios. These indicators result to be: strongly correlated with each other, powerful in identifying the disturbed and relaxed population, characterised by a unimodal distribution and not strongly influenced by systematic uncertainties. In order to obtain a continuous classification of the CHEX-MATE objects, we combined these four parameters in a single quantity, M, which represents the grade of relaxation of a system. On the basis of the M value, we identified the most extreme systems of the sample, finding 15 very relaxed and 27 very disturbed galaxy clusters. From a comparison with previous analysis on X-ray selected samples, we confirmed that the Sunyaev-Zeldovich (SZ) clusters tend to be more disturbed. Finally, by applying our analysis on a simulated sample, we found a general agreement between the observed and simulated results, with the only exception of the concentration. This latter behaviour, is partially related to the presence of particles with high smoothed-particle hydrodynamics density in the central regions of the simulated clusters due to the action of the idealised isotropic thermal Active Galactic Nuclei (AGN) feedback

Forest leaf litter beetles of Taiwan: first DNA barcodes and first insight into the fauna

We report the publication of 953 DNA barcodes of forest leaf litter beetles from central Taiwan, in total representing 334 spe- cies of 36 beetle families. This is the first bulk of data from the Taiwanese Leaf Litter beetles project focused on uncovering the under-explored diversity of leaf litter beetles across Taiwan. Based on these data, we provide the first records of the following taxa for Taiwan: family Sphindidae (genus Aspidiphorus Ziegler, 1821); tribes Trichonychini, Ctenistini, and Bythinoplectini (all Staphylinidae: Pselaphinae); genera Gyrelon Hinton, 1942, Thyroderus Sharp, 1885, Cautomus Sharp, 1885 (all Cerylonidae), Dermatohomoeus Hlisnikovský, 1963 (Leiodidae), Paraploderus Herman, 1970 (Staphylinidae: Oxytelinae), Thinocharis Kraatz, 1859 (Staphylinidae: Paederinae), Cephennodes Reitter, 1884, Napoconnus Franz, 1957 (both Staphylinidae: Scydmaeninae), Bicava Belon, 1884 (Latridiidae), Otibazo Morimoto, 1961, Seleuca Pascoe, 1871 and Acallinus Morimoto, 1962 (all Curculioni- dae); species Oodes (Lachnocrepis) japonicus (Bates, 1873) (Carabidae: Licininae), Drusilla obliqua (Bernhauer, 1916) (Staphylin- idae: Aleocharinae) and Coccotrypes advena Blandford, 1894 (Curculionidae: Scolytinae). The records of Anapleus Horn, 1873 (Histeridae) and Batraxis Reitter, 1882 (Staphylinidae: Pselaphinae) have been confirmed. The male of Sivacrypticus taiwanicus Kaszab, 1964 (Archeocrypticidae) is described for the first time. Gyrelon jenpani Hu, Fikáček & Matsumoto, sp. nov. (Cerylon- idae) is described, illustrated, and compared with related species. DNA barcodes associated larvae of 42 species with adults, we are concisely illustrating some of these: Oodes japonicus, Perigona cf. nigriceps Dejean, 1831 (both Carabidae), Ptilodactyla sp. (Ptilodactylidae), Maltypus ryukyuanus Wittmer, 1970 (Cantharidae), Drusilla obliqua, Myrmecocephalus brevisulcus (Pace, 2008), Diochus sp., Mimopinophilus sp.
