The system should return a JSON schema containing a list of sentences.A new genus, Archaeoluprops, and species groehni, are reported, having been discovered within the Eocene Baltic amber. And the species. Sentences, a list of, this JSON schema returns. This fossil Lagriinae (Tenebrionidae) darkling beetle shares superficial characteristics with species of the Lupropini and Goniaderini tribes—a robust pubescent body and elytra with striations. Yet, this beetle is uniquely characterized by the absence of intersegmental membranes between abdominal ventrites 3-5 (a tentyrioid feature), leading to the absence of defensive glands. Distinguishing the new tribe Archaeolupropini from all past and present lagriine lineages is made possible by a combination of plesiomorphic and apomorphic features, alongside other noteworthy differences. Return this JSON schema consisting of a list of sentences. The genus *Archaeoluprops*, likely a fundamental branch in the evolutionary tree, relates to the non-fundamental lineage comprising Lagriini, Chaerodini, Lupropini, Pycnocerini, Goniaderini (potentially Gonialaenini), and Laenini. The Baltic amber lagriine tribes are nowhere to be found in the extant faunas of the middle latitudes of Europe.Approximately 38,000 species comprise the Cerambycidae family, a substantial grouping within the Coleoptera. Progress in understanding Brazil's Cerambycidae has been notable over the last five decades; nonetheless, some regions, including the Brazilian semi-arid region, require further exploration. The Zoology Museum of the Universidade Estadual de Feira de Santana provides an updated checklist of Cerambycidae from that region, based on previous publications, existing checklists and catalogs, and the study of 331 specimens representing 72 species, 58 genera, 26 tribes and three subfamilies. Across nine states in Brazil's semi-arid region, encompassing 75 municipalities, the Cerambycidae family presents a remarkable array of diversity: four subfamilies, 633 species, 303 genera, and 58 tribes. A map is provided to demonstrate the distribution pattern of Cerambycidae species within the semi-arid region. Researchers unveil the distinct characteristics of the newfound species, Eburodacrys boteroi sp. This JSON schema, which contains sentences, should be returned as a list.

The Lamiinae subfamily is composed of a multitude of species with unique characteristics. A guide to the identification of the respective genera now lists the new species discovered. Bahia State now boasts a new species, Antodice kyra Martins & Galileo, 1998; a new record for the Brazilian semi-arid region is Chevrolatella tripunctata (Chevrolat, 1862); Colobothea rubroornata Zajciw, 1962 is now documented in both Bahia State and the Brazilian semi-arid region; and Odontocera bilobata Zajciw, 1965 is likewise newly recorded in both Bahia State and the Brazilian semi-arid region. Sampling in the Brazilian semi-arid region is clearly inadequate in some locations, necessitating the initiation of new, comprehensive inventory studies.A comprehensive revision and rediagnosis is undertaken for the Neotropical flower fly genus Argentinomyia, belonging to the Diptera Syrphidae. sbc-115076antagonist A key to the Neotropical Bacchini and Melanostomini genera, now updated, is presented here.

Colombia, Ecuador, and Peru; three South American countries. Taxonomic revision proposes new synonyms for four species as follows: Melanostoma melanocerum (Williston, 1891) is now synonymous with Argentinomyia catabomba (Williston, 1891), Braziliana columbiana (Enderlein, 1935) is synonymous with Argentinomyia fastigata (Fluke, 1945), Braziliana peruviana (Shannon, 1927) maintains its current designation, Braziliana thiemei (Enderlein, 1935) is synonymous with Argentinomyia longicornis (Walker, 1836), and Rhysops funerea (Hull, 1949) is synonymous with Argentinomyia nigrans (Fluke, 1945). Lectotypes are to be assigned to the taxa Melanostoma catabombum Williston, 1891; Melanostoma crenulatum Williston, 1891; Melanostoma longicornis Williston, 1888; Melanostoma melanocerum Williston, 1891; and Pipiza longicornis Walker, 1836. The 47 recognized species are subject to a comprehensive review, leading to the redescription of 26 species and the introduction of a new key for the 41 species whose status has been validated. Comprehensive information encompassing high-resolution color photographs of the complete morphology, illustrative depictions of the male anatomy, field photographs, comparative diagnoses, and synonymous designations is provided. The biogeographical affinity and level of endemism of known species, as displayed in their mapped distribution ranges, are discussed. The genus's female genitalia are described for the first time, a significant advancement. Following its rediscovery, Argentinomyia berthae (Lima, 1946) has undergone a complete redescribing, including the crucial designation of a neotype. Arguinomyia scitula (Williston, 1888)'s taxonomic status remains ambiguous, prompting the need for more detailed research. Taxonomic considerations are provided for Argentinomyia aenea (Willistoni, 1891) and A. huitepecensis, described by Montoya in 2020. This revision underscores a previously underestimated diversity within the genus, evidenced by the high diversity, close biogeographic relationships, significant endemism, novel national records, and the appreciable morphological variation. Countless new species undoubtedly remain to be discovered in the uncharted areas of the Neotropics. Our investigation, encompassing a meticulous morphological evaluation and a refined biogeographical distribution, sets the stage for exploring the phylogenetic relationships, historical biogeography, diversification patterns, and conservation efforts of Argentinomyia, which will be further developed in subsequent publications.The taxonomic study of Afrotropical species within the Anterhynchium genus, established by de Saussure in 1863, is presented. Subspecies are sometimes promoted to specific rank; Anterhynchium argenteopilosellum (Giordani Soika, 1937) serves as an illustration of this. Statistically significant, the *bugandanum* species, as documented by Giordani Soika in 1987. Giordani Soika's formal taxonomy in 1987 includes the species *A. cariosum*, elevating it to a recognized taxonomic entity. A. denticulatum (Mocsary, 1903), is now considered a distinct species, according to November records. November's scientific findings officially establish A. sulphureomaculatum (von Schulthess, 1928) as a distinct species. The returned JSON schema should be a list of sentences. Alternative names are proposed for Anterhynchium fallax (de Saussure, 1852), considered synonymous with Rhynchium luctuosum, as described by Gerstacker in 1857. Epiodynerus grandidieri limbatulus, a synonym for Anterhynchium grandidieri, was first defined by Giordani Soika in 1991, replacing the earlier nomenclature by de Saussure (1890). Anterhynchium grayi (de Saussure, 1855) is a taxonomic equivalent of Synagris inermis var. (nov.), a newly recognized variant. Taxonomically speaking, atrata, described by Mocsary in 1903, has since been assigned a synonymous designation.
