ZooKeys, Год журнала: 2024, Номер 1194, С. 1 - 981

Опубликована: Март 13, 2024

More than 4700 nominal family-group names (including for fossils and ichnotaxa) are nomenclaturally available in the order Coleoptera. Since each name is based on concept of its type genus, we argue that stability used classification beetles depends accurate nomenclatural data genus. Following a review taxonomic literature, with focus works potentially contain species designations, provide synthesis associated genus For author(s), year publication, page number given as well current status (i.e., whether treated valid or not) classification.

Because importance Principle Priority zoological nomenclature, information date publication references cited this work, when known.

How Does Landscape Structure Affect Dung Beetle Assemblages in Amazon Cities?

ABSTRACT The growth of cities is one the main direct and indirect factors responsible for loss native vegetation cover. Urbanization directly affects biological communities inhabiting forest remnants inserted in cities, compromising maintenance urban natural ecosystems. By understanding effects landscape transformation due to urbanization, we can have insights regarding distribution land uses that allow a proper This work assessed structure variables (forest cover, agricultural area, edge density, number patches) on dung beetle assemblages functional groups (i.e., diet resource removal strategy) sampled 38 sites located along an urban–rural gradient six belonging metropolitan area Manaus Central Amazonia. Losses cover were most determining factor, negatively affecting species richness, abundance, body size. increases agriculture affected while density positively their abundance. patches abundances—except dweller species—and size diet‐generalist species. These results demonstrate changes ecological diversity caused by urbanization are driven mostly loss, although configuration important study contributes how amount tropical affect taxonomic assemblages.

The Ecuadorian territory is divided into four natural regions: the coastal lowlands, Andean highlands, Amazon basin, and Galapagos Islands. Each of these regions has its own ecosystems specific vegetation. purpose this work to compile an updated catalog Scarabaeinae (Coleoptera: Scarabaeidae) Ecuador that includes distributional data several nomenclatural acts. We compiled from 25 scientific collections, with examination 13,550 scarabaeines; additionally, 390 bibliographic references were reviewed for their taxonomic histories. fauna represented by 33 genera 223 species, 45 range-restricted species; 27 species erroneously recorded country. following acts are made: (A) two new status as valid species: Canthon (Glaphyrocanthon) ohausi Balthasar, 1939, stat. n., Deltochilum (Calhyboma) arrowi Paulian, 1939 n.; (B) one synonym: Uroxysmagnus 1940 = Uroxyslatesulcatus Bates, 1891, syn. (C) revalidated names: Canthidium (Canthidium) orbiculatum (Lucas, 1857) Dichotomius (Luederwaldtinia) fortepunctatus (Luederwaldt, 1923); (D) ten lectotypes designated for: Choeridiumorbiculatum Lucas, 1857; Choeridiumcupreum Blanchard, 1846; Canthidiumcoerulescens 1939; Canthonangustatus Harold, 1867; Canthonangustatusohausi Deltochilumtessellatum 1870; Pinotusfortepunctatus Luederwaldt, 1923; Pinotusglobulus Felsche, 1901; 1891; 1940. type specimens related illustrated maps geographical distribution all provided.

Towards a comprehensive taxonomic revision of the Neotropical dung beetle subgenus Deltochilum (Deltohyboma) Lane, 1946 (Coleoptera: Scarabaeidae: Scarabaeinae): Division into species-groups

Deltochilum Eschscholtz, 1822 is perhaps the most speciose genus of tribe Deltochilini sensu Tarasov & Dimitrov (2016) (Scarabaeidae: Scarabaeinae) and has been traditionally divided into eight subgenera. Among them, subgenus Deltohyboma Lane, 1946, with 47 species, five which are described here ( D . genieri sp. nov. , gilli susanae bolivariensis inesae ), at least 165 species still undescribed. Due to large number for practical purposes, 19 species-groups, left as incertae sedis This division species-groups will help in reliable identification aid completion revision subgenus. report first part taxonomic ; it based on examination all type specimens almost 9,800 approximately 1,200, mostly males, had their genitalia studied.

The dung beetles of Venezuela (Coleoptera: Scarabaeidae: Scarabaeinae): catalogue and updated distribution

European Journal of Taxonomy, Год журнала: 2024, Номер 959

Опубликована: Окт. 11, 2024

Venezuela’s diverse land ecosystems are grouped into four major regions (coast-islands, low plains, hills and mountains), ranging from sea level up to 4978 m. The Scarabaeinae (Scarabaeidae, Coleoptera) currently encompass 278 genera 6837 species worldwide, but poorly inventoried in Venezuela. We reviewed the literature material housed at entomological collection of Universidade Federal de Mato Grosso (CEMT), Cuiabá, Brazil, found 32 149 dung beetles as certainly present Twenty-four these are, far current knowledge goes, endemic country, while another 34 restricted Venezuela neighbouring countries Colombia, Trinidad Tobago, Guyana. Additionally, 36 deemed potential inhabitants whilst 14 others previously recorded part Venezuelan fauna here concluded not be actually there. Complete is listed for each genus species, information on type material, examined, worldwide distribution, records also presented.

Bait attractiveness changes community metrics in dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae)

Ecology and Evolution, Год журнала: 2023, Номер 13(4)

Опубликована: Апрель 1, 2023

Species relative abundance (SRA) is an essential attribute of biotic communities, which can provide accurate description community structure. However, the sampling method used may have a direct influence on SRA quantification, since use attractants (e.g., baits, light, and pheromones) introduce additional sources variation in trap performance. We tested how aided by baits affect data therefore alter derived metrics. our hypothesis dung beetles using from flight interception traps (FITs) as baseline to evaluate baited pitfall Our objective was assess effect bait attractiveness estimates assemblage metrics when sampled with human feces.Dung were at three terra firme primary forest sites Brazilian Amazon. To achieve objective, we (i) identified species variable levels attraction feces; (ii) assessed differences SRA; (iii) most commonly diversity (Shannon Simpson indices). less highly attracted used, because showed greater abundances within samples compared baseline. Assemblages tend show lower higher dominance than those unbaited FITs. findings suggest that for ecological questions focused abundance, lead inaccurate conclusions regarding Although beetles, same could be observed other insect taxa are also traps. highlight need further studies groups elucidate any potential effects baits.
