Bumblebees (Bombus Latreille, 1802), because of their large body size, bright colours and activity at times and places that coincide with biologists, are an example of a group of insects that is particularly well represented in museum collections. This is important if taxonomic revisions are to achieve greater comparability among species. Bumblebees have also attracted particular attention because they are especially ecologically and economically valuable for pollination in north temperate regions, where they are now becoming increasingly threatened. I argue that the what, the where, and the how of effective conservation management may be informed by understanding the divergent characteristics that have affected their biogeographical past: by helping us to see ‘the woods’, not just ‘the trees’, of their habitat needs. Identifying suitable habitat should be part of reconstructing historical biogeography within taxonomic revisions. For bumblebees, for example, biogeographical analysis associates major taxonomic groups either with flower-rich lowland grasslands or with flower-rich montane grasslands, highlighting their contrasting requirements for: nest sites, flowers of different depths, pollen-plant families, and especially the differing importance of early spring and late summer flowers for breeding success. This broad view of species groups helps filter the less important idiosyncrasies from local case studies in order to focus conservation actions.

A new species of Liolaemus is described from southwest of the town of Añelo, Neuquén Province, Argentina. Integrative evidence methodology of external morphological characters and molecular phylogenetic analyses of mitochondrial DNA (cyt-b) is used to place the new species to the species group of Liolaemus boulengeri. The new species is phenotypically close to L. mapuche. The new Liolaemus is medium to large in size (males 77.64–83.98 mm, females 72.88–78.58 mm), with evident sexual dichromatism. Genetic distances of the mtDNA (cyt-b) between the new species and its closest relative species are greater than 3% (L. cuyanus 7.48–12.02%; L. josei 7.56–9.60%; L. puelche 8.23–9.93%; L. mapuche 8.51–9.79%). Molecular and morphological phylogenetic results show L. mapuche as the sister species of the new one. The new species is larger than L. mapuche. Dorsal and ventral scales are more numerous in the new species than in L. mapuche, precloacal pores in females are present in L. mapuche and absent in the new species. It has strict psammophilic habits, using sand mounds and sheltering, under Alpataco (Neltuma alpataco) bushes. The L. boulengeri group now contains 75 species distributed in Argentina, Bolivia, Brazil, Chile, Paraguay, Peru and Uruguay.

Three new species of the genus Pelodera Schneider, 1866 viz., P. indica sp. nov., P. adeeli sp. nov. and P. paratretzeli sp. nov. collected from dung beetles and P. cylindrica (Cobb, 1898) collected from soil samples, are described and illustrated. Pelodera indica sp. nov. is characterised by sexual dimorphism in anterior region, cupola-shaped tail with a spike; males having punctated, striated and lobed bursa with no genital papillae originating anterior to cloaca. Pelodera adeeli sp. nov. is characterised by coarsely annulated cuticle; relatively narrow stoma; tail conoid without spike; males with punctated, lobed bursa and nine pairs of genital papillae arranged in a 2/1+2+P+3+1 configuration. Pelodera paratretzeli sp. nov. is characterised by sexual dimorphism in anterior region, stoma wide with three well-developed metastegostomal denticles; tail cupola-shaped with a long spike; males having spicules fused distally up to 12–14% of spicule length; bursa peloderan, anteriorly closed and punctated with nine pairs of genital papillae arranged in a 3/2+P+3+1 configuration. Pelodera cylindrica is described with additional details. The comparative analysis as well as phylogenetic relationship of the species belonging to the coarctata group have been elaborated by incorporating scanning electron microscopic observations. Information on the biogeographical distribution has also been provided.

Scelolabes, historically is a monotypic genus of Ocydromiinae (Hybotidae) that for a long time was not studied due to the absence of the type of the type species (Scelolabes bivittatus Philippi), which is probably lost or destroyed. In this context, we propose an updated diagnosis and redescription of the genus, based on specimens identified by experts and in agreement with the original description of Philippi (1865), as well as illustrating male and female terminalia for the first time. This serves as an aid to discuss and corroborate the status of Scelolabes in the Neotropical region as a genus distinct from Hoplopeza. In addition, two new species are described, and an identification key and a distribution map are provided to all the Neotropical species of the genus.

Paramacrobiotus bengalensis sp. nov. was discovered in a moss sample collected from a tree in West Bengal, India. We describe this new species using detailed morphological and morphometric data obtained from phase contrast microscopy and scanning electron microscopy, along with molecular and phylogenetic data analyses. Due to the presence of a cap-like structure at the distal portion of egg processes, the new species showed the highest similarity with Paramacrobiotus garynahi (Kaczmarek, Michalczyk & Diduszko, 2005), Paramacrobiotus alekseevi (Tumanov, 2005), Paramacrobiotus filipi Dudziak, Stec & Michalczyk, 2020, Paramacrobiotus sagani Daza, Caicedo, Lisi & Quiroga, 2017, Paramacrobiotus vanescens (Pilato, Binda & Catanzaro, 1991) and Paramacrobiotus gadabouti Kayastha, Stec, Mioduchowska & Kaczmarek, 2023. However, it can be differentiated from them by some morphological and morphometric characteristics. The genetic data corroborated our phenotypic outcome further supporting the new species hypothesis.

Aname L. Koch, 1873 is an incredibly diverse genus of mygalomorph spiders endemic to Australia, occurring from coast to coast in tropical, semi-arid and arid bioregions. They are relatively gracile mygalomorph spiders that build open burrows, sometimes with a secondary entrance that functions as an escape chute. The genus currently contains 48 species, but the true diversity is likely to be closer to 200 species. Here we describe five new species (A. ningaloo sp. nov., A. salina sp. nov., A. tatarnici sp. nov., A. tenuipes sp. nov. and A. wongalara sp. nov.), primarily based on specimens collected on Bush Blitz expeditions in Western Australia (Cape Range, 2019), South Australia (Great Victoria Desert, 2017) and the Northern Territory (Wongalara, 2012). We complement these descriptions with a molecular phylogenetic analysis to place all new species into an existing phylogenetic framework.
Aname L. Koch, 1873是澳大利亚特有的mygalomorph蜘蛛的一个令人难以置信的多样化属，在热带，半干旱和干旱的生物区从海岸到海岸都有出现。它们是一种相对柔软的mygalomorph蜘蛛，它们会建造开放的洞穴，有时还会有一个次要的入口，作为逃生通道。该属目前包含48种，但真正的多样性可能接近200种。在这里，我们描述了五个新种(A. ningaloo sp. nov, A. salina sp. nov, A. tatarnici sp. nov, A. tenuipes sp. nov和A. wongalara sp. nov)，主要基于在西澳大利亚(Cape Range, 2019)，南澳大利亚(Great Victoria Desert, 2017)和北领地(wongalara, 2012)的布什闪电战探险中收集的标本。我们用分子系统发育分析来补充这些描述，将所有新物种放入现有的系统发育框架中。

Hebius beddomei (Günther, 1864) is an endemic natricine colubrid snake species from the biodiverse Western Ghats, India. A recent molecular phylogeny provided evidence for the paraphyly of the genus Hebius, with Hebius beddomei recovered as sister to a clade containing Fowlea and Atretium. Freshly collected specimens and existing museum material allowed us to elucidate the generic status of the species and identify two distinct populations, one of which is described as a new species. A new genus, Sahyadriophis gen. nov., is proposed to accommodate Sahyadriophis beddomei gen. et. comb. nov., and Sahyadriophis uttaraghati gen. et. sp. nov. is described as a new species from the northern part of the range. The discovery of a new Oligocene divergent lineage, Sahyadriophis gen. nov., highlights the role of the Western Ghats as a source of relic lineages.

Costanana DeLong & Freytag, 1972 is a Neotropical genus of leafhoppers currently comprising 13 species with a wide distribution from Mexico to Argentina. In this study, eight new species of Costanana are described, C. xenomorpha sp. nov. from Department of Cuzco, Peru, and seven Brazilian species: C. alata sp. nov. from Minas Gerais State; C. bifida sp. nov. from Paraná and Mato Grosso states; C. cifi sp. nov., C. obtusa sp. nov. and C. piraquarensis from Paraná State; C. luzi sp. nov. from Distrito Federal; and C. rubromarginata sp. nov. from Mato Grosso and Pará states. We propose that Costanana cella DeLong & Freytag, 1972 is a junior synonym of C. praecellens (Stål, 1862) and C. asymmetrica DeLong & Freytag, 1972 is a junior synonym of Gypona viridans DeLong & Martinson, 1972. Costanana costata DeLong &Freytag, 1972 and C. flavicosta (Stål, 1862) are transferred to Gypona Germar, 1821, C. minuta (Spångberg, 1878) is transferred to Acuponana DeLong & Freytag, 1970 and Gypona nupera Van Duzee, 1907 is transferred to Costanana. Gypona costata comb. nov. and Costanana santana DeLong & Wolda, 1983 are newly recorded from Pernambuco State, and Gypona flavicosta comb. nov. is recorded from Espírito Santo and Paraná states, Brazil. The female genitalia of Costanana flavina DeLong & Freytag, 1972, C. praecellens and Gypona flavicosta comb. nov. are described and illustrated for the first time and a brief note on feeding behavior is given for C. flavina and C. praecellens. A key to males and a new diagnosis are provided for Costanana. We also describe and illustrate Metacostana cornuta gen. et sp. nov., a new Brazilian genus for Gyponini sharing characteristics with Costanana, Acuthana Domahovski & Cavichioli, 2018, Domahovana Silva et al., 2022 and Dumorpha DeLong & Freytag, 1975.

In this study, eight new species of Costanana are described, C. xenomorpha sp. nov. from Department of Cuzco, Peru, and seven Brazilian species: C. alata sp. nov. from Minas Gerais State; C. bifida sp. nov. from Paraná and Mato Grosso states; C. cifi sp. nov., C. obtusa sp. nov. and C. piraquarensis from Paraná State; C. luzi sp. nov. from Distrito Federal; and C. rubromarginata sp. nov. from Mato Grosso and Pará states. We propose that Costanana cella DeLong & Freytag, 1972 is a junior synonym of C. praecellens (Stål, 1862) and C. asymmetrica DeLong & Freytag, 1972 is a junior synonym of Gypona viridans DeLong & Martinson, 1972. Costanana costata DeLong &Freytag, 1972 and C. flavicosta (Stål, 1862) are transferred to Gypona Germar, 1821, C. minuta (Spångberg, 1878) is transferred to Acuponana DeLong & Freytag, 1970 and Gypona nupera Van Duzee, 1907 is transferred to Costanana. Gypona costata comb. nov. and Costanana santana DeLong & Wolda, 1983 are newly recorded from Pernambuco State, and Gypona flavicosta comb. nov. is recorded from Espírito Santo and Paraná states, Brazil. The female genitalia of Costanana flavina DeLong & Freytag, 1972, C. praecellens and Gypona flavicosta comb. nov. are described and illustrated for the first time and a brief note on feeding behavior is given for C. flavina and C. praecellens. A key to males and a new diagnosis are provided for Costanana. We also describe and illustrate Metacostana cornuta gen. et sp. nov., a new Brazilian genus for Gyponini sharing characteristics with Costanana, Acuthana Domahovski & Cavichioli, 2018, Domahovana Silva et al., 2022 and Dumorpha DeLong & Freytag, 1975.","PeriodicalId":12062,"journal":{"name":"European journal of taxonomy","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49465207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a preliminary discussion about cauliflory, sexual dimorphism and biogeographic patterns in Drypetes Vahl (Putranjivaceae Endl.), focused on Africa. We also present a taxonomic treatment for two new species of cauliflorous trees of this genus from the rainforests of western Central Africa, one endemic to Gabon and known from six gatherings, D. aphanes Quintanar, D.J.Harris & Barberá sp. nov., and the other distributed in Gabon and the Republic of the Congo, D. cauta D.J.Harris, Barberá & Quintanar sp. nov., also known from another six gatherings. They are presented along with D. gabonensis Pierre ex Hutch., known from 25 gatherings made throughout western Central Africa, a species with markedly dimorphic flowers between sexes compared to the rest of the species in the genus. Specimens of these two new species have been confused with D. gabonensis due to some morphological resemblances. This treatment includes the detailed descriptions of these three species, the typification of their names, a comparative table summarizing their main morphological differences, an identification key, an illustration and information about their habitat and distribution. A provisional IUCN Red List assessment shows that D. gabonensis and D. cauta sp. nov. are ‘Vulnerable’ species, and D. aphanes sp. nov. is ‘Endangered’. After the publication of these new species, Drypetes consists of 86 species in continental Africa and the Malagasy Region and 219 species for the whole world.
