In this study, we revise the taxonomy of the endemic Mexican genus Ceratotrupes Jekel, 1865. It comprises three species, distributed in the Sierra Madre Occidental and Trans-Mexican Volcanic Belt (Ceratotrupes fronticornis (Erichson, 1847) and Ceratotrupes bolivari Halffter & Martínez, 1962), and the Sierra Madre del Sur (Ceratotrupes sturmi (Jekel, 1865)). We confirm C. mniszechi (Jekel, 1865) as a junior subjective synonym of C. sturmi. The examination of the holotype of C. sturmi and specimens recently collected in the Sierra Sur de Oaxaca (Oaxaca) and Omiltemi (Guerrero) allowed us to identify and describe a new species, Ceratotrupes gonzaloi sp. nov. from Omiltemi, Guerrero. We redescribe the morphology of C. sturmi and provide a diagnostic key to the four members of the genus Ceratotrupes. Photographs of the habitus and male genitalia of the four species, a distribution map, and observations on their ecology and biogeography are provided.

The number of currently described species of Afrotropical parasitoid wasps does not reflect the true species diversity. One of the most severely understudied parasitoid wasp groups is Ceraphronoidea. In this first study on Afrotropical mainland Ceraphronoidea in more than 20 years, which is also the first ever taxonomic monograph focusing on Ceraphronidae, we describe 88 new species of Ceraphronidae (85 new species) and Megaspilidae (3 new species) from Kakamega Forest (Kenya), Mt.

The early Tournaisian (Early Carboniferous; Mississippian) ammonoids from the classical abandoned limestone quarry of Gattendorf (Upper Franconia) are revised, using the historical collections as well as so far undescribed material. The ammonoid assemblage is composed of prionoceratid ammonoids of the six genera Mimimitoceras, Paragattendorfia, Stockumites, Acutimitoceras, Gattendorfia and Gattenpleura, which indicate a stratigraphic position near the Devonian–Carboniferous boundary in the earliest Carboniferous. The new species Stockumites hofensis sp. nov. and S. nonaginta sp. nov. are described.

The railway cutting near Oberrödinghausen at the northern margin of the Rhenish Mountains is the cardinal section for the investigation of Early Tournaisian (Early Carboniferous; Mississippian) ammonoids. The ammonoids from the Hangenberg Limestone (= Gattendorfia Limestone) of this and neighbouring outcrops are revised here, using the historical collections as well as undescribed new material. The ammonoid assemblages are composed of a total of 67 species, which occur in four successive ammonoid zones. The assemblages are composed of predominant prionoceratids (Order Goniatitina) with the twenty genera Mimimitoceras (two species), Globimitoceras (one species), Paragattendorfia (two species), Kornia (three species), Stockumites (eleven species), Acutimitoceras (two species), Costimitoceras (one species), Nicimitoceras (four species), Imitoceras (one species), Voehringerites (one species), Gattendorfia (eight species), Zadelsdorfia (two species), Kazakhstania (one species), Gattenpleura (one species), Weyerella (three species), Hasselbachia (three species), Paprothites (five species), Pseudarietites (three species), Rodingites (two species), Paralytoceras (one species) as well as subordinate eocanitids (Order Prolecanitida) with the genera Eocanites (eight species) and Nomismocanites (one species). The new genera Rodingites gen. nov. and Nomismocanites gen. nov. as well as the new species Mimimitoceras perditum sp. nov., Kornia fibula sp. nov., Kornia acia sp. nov., Stockumites parallelus sp. nov., Stockumites voehringeri sp. nov., Acutimitoceras ucatum sp. nov., Acutimitoceras paracutum sp. nov., Imitoceras initium sp. nov., Gattendorfia rhenana sp. nov., Gattendorfia bella sp. nov., Gattendorfia valdevoluta sp. nov., Gattendorfia schmidti sp. nov., Gattendorfia corpulenta sp. nov., Gattendorfia immodica sp. nov., Zadelsdorfia oblita sp. nov., Weyerella lenis sp. nov., Hasselbachia erronea sp. nov., Paprothites beckeri sp. nov., Paprothites kullmanni sp. nov., Eocanites delicatus sp. nov. and Nomismocanites raritas gen. et sp. nov. are described from Oberrödinghausen. Mimimitoceras mina sp. nov., Stockumites marocensis sp. nov., Zadelsdorfia zana sp. nov. and Kazakhstania kana sp. nov. are newly named for material from the Anti-Atlas of Morocco.

We provide a floristic account for the Begoniaceae of Peru. The family is represented in Peru by 76 species, which are all members of the genus Begonia and represent eighteen sections. Twelve new species are described: B. condorensis Jara & Moonlight sp. nov., B. deltoides Moonlight sp. nov., B. huancabambae Moonlight sp. nov., B. imbrexiformis Moonlight sp. nov., B. longinqua Moonlight sp. nov., B. longitepala Moonlight sp. nov., B. nunezii Moonlight sp. nov., B. occultata J.P.Allen & Moonlight sp. nov., B. pedemontana Moonlight sp. nov., B. serratistipula Moonlight sp. nov., B. vargasii Moonlight sp. nov. and B. yuracyacuensis Moonlight sp. nov. We also provide four new records for the country: B. andina Rusby, B. brandbygeana L.B.Sm. & Wassh., B. neoharlingii L.B.Sm. & Wassh. and B. unilateralis Rusby. We provide an identification key to all species. The ecology, distribution, and conservation status of all Peruvian Begonia species are discussed, including provisional IUCN threat assessments. Most species are illustrated by either historical illustrations, contemporary photographic plates, or line drawings. Twenty-six names are newly synonymised including fifteen previously accepted species, and we designate eighty-three lectotypes, four neotypes, and four epitypes.

The North American-Caribbean genera Pholcophora Banks, 1896 and Tolteca Huber, 2000 are representatives of Ninetinae, a group of small, cryptic, and thus poorly known pholcid spiders. We present the first comprehensive revisions of the two genera, including extensive SEM data and descriptions of seven new species from Mexico (Pholcophora mazatlan Huber sp. nov., P. papanoa Huber sp. nov., P. tehuacan Huber sp. nov., Tolteca huahua Huber sp. nov., T. manzanillo Huber sp. nov., T. oaxaca Huber sp. nov., and T. sinnombre Huber sp. nov.). We add new CO1 sequences of nine species to previously published molecular data and use these for a preliminary analysis of relationships. We recover a North American-Caribbean clade including ‘true’ (mainland) Pholcophora, Tolteca (Mexico), and a Caribbean clade consisting of the genus Papiamenta Huber, 2000 (Curaçao) and Caribbean ‘Pholcophora’. First karyotype data for Tolteca (2n♂ = 13, X1X2Y and 15, X1X2Y, respectively) reveal a strong reduction of the number of chromosome pairs within the North American-Caribbean clade, and considerable karyotype differentiation among congeners. This agrees with considerable CO1 divergence among species of Tolteca but contrasts with very inconspicuous morphological divergence. Environmental niche analyses show that the widespread P. americana Banks, 1896 (western USA, SW Canada) occupies a very different niche than its Mexican congeners and other close relatives. Caribbean taxa also have a low niche overlap with ‘true’ Pholcophora and Tolteca, supporting the idea that Caribbean ‘Pholcophora’ are taxonomically misplaced.
北美-加勒比地区的Pholcophora Banks属(1896年)和Tolteca Huber属(2000年)是九蛛科的代表,九蛛科是一组小型的、隐蔽的、因此不为人知的phoolcid蜘蛛。本文首次对这两个属进行了全面的修订,包括广泛的扫描电镜数据和对来自墨西哥的7个新种(phocophora mazatlan Huber sp. nov., P. papanoa Huber sp. nov., P. tehuacan Huber sp. nov., Tolteca huahua Huber sp. nov., T. manzanillo Huber sp. nov., T. oaxaca Huber sp. nov.和T. sinnombre Huber sp. nov.)的描述。我们将九个物种的新CO1序列添加到先前发表的分子数据中,并使用这些数据进行初步的关系分析。我们在Tolteca(墨西哥)恢复了一个北美-加勒比分支,包括“真正的”(大陆)phocophora,以及2000年由Papiamenta Huber属(curaao)和加勒比“phocophora”组成的加勒比海分支。Tolteca的第一个核型数据(分别为2n♂= 13,X1X2Y和15,X1X2Y)显示了北美-加勒比分支中染色体对数量的强烈减少,并且在同系物中存在相当大的核型分化。这与托尔特克物种间相当大的co2差异一致,但与非常不明显的形态差异形成对比。环境生态位分析表明,1896年分布广泛的美洲斑滩(美国西部,加拿大西南部)与其墨西哥同系物和其他近亲所占据的生态位非常不同。加勒比分类群与“真正的”phocophora和Tolteca的生态位重叠也很低,这支持了加勒比“phocophora”在分类学上错位的观点。

Caribbean taxa also have a low niche overlap with ‘true’ Pholcophora and Tolteca, supporting the idea that Caribbean ‘Pholcophora’ are taxonomically misplaced.","PeriodicalId":12062,"journal":{"name":"European journal of taxonomy","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43641292","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}

The fauna of Loricifera along a north-south longitudinal transect following the Atacama Trench was explored. Whereas no loriciferans were collected from the actual trench, the continental slope and surrounding abyssal plains yielded two species of Rugiloricus and two of Pliciloricus. All four species are considered as new to science, but only one of them could be formally described. The new species, Pliciloricus ukupachaensis sp. nov., is closely related with the North Atlantic Pliciloricus leocaudatus, and the two species share different morphological traits, including an enlarged anal field with conspicuous pentagonal and hexagonal fields formed by strong, cuticular ridges. Among other peculiar traits, the new species is characterised by having strongly reduced trichoscalid plates and no double trichoscalids. Comparison with previously published, unidentified specimens suggests that the new species’ distributional range might reach as far as Oregon off the US west coast.

Recently, it has been hypothesized that the wide distribution of A. fiuzai Salles & Lugo-Ortiz is due to a wide diagnosis and conflicting keys. The same arguments can be applied to A. kallawaya Nieto. In order to test this hypothesis, we revised the type material of A. fiuzai, literature of A. kallawaya, and part of the recorded specimens in Brazil. As a result, three new species from previous records are recognized: Apobaetis pasternakae sp. nov., former A. fiuzai in Amazonas, Roraima and Maranhão states; Apobaetis jaquelinae sp. nov., former A. fiuzai in Rondônia State; Apobaetis luanae sp. nov., former A. kallawaya in Rondônia State. The new data showed that A. fiuzai does not occur in the Amazon Biome and A. kallawaya does not occur in Brazil. Records of A. fiuzai that could not be reviewed in this study are treated as putative and should be evaluated in the light of the new evidence. We also studied the intraspecific variation in A. fiuzai and A. pasternakae sp. nov. The pigment pattern of the nymphs was not considered a robust characteristic for the species differentiation due to the wide variation in and between populations, and interspecific similarity of many features. On the other hand, classical morphological characters such as mouthparts, legs, spines of terga, paraproct and caudal filaments have minimal variation, stable and reliable for specific identification.

The ant genus Temnothorax Mayr, 1861 (Myrmicinae, Crematogastrini) is diverse with 498 species described. Species are distributed predominately within the northern hemisphere with species richness decreasing closer to the tropics; contrary to other ant genera overall. In Southeast Asia, richness is relatively low and knowledge on the genus remains fragmentary, likely due to poor sampling efforts compared to temperate regions. Here, using specimens from recent sampling efforts, Temnothorax is reported for the first time from the Hong Kong Special Administrative Region. Two new species, T. barrettoi Hamer & Guénard sp. nov. and T. haveni Lee, Hamer & Guénard sp. nov., are described based on qualitive morphological characters, with additional morphometric data also gathered. An updated key, as well as a distributional checklist of Temnothorax species from mainland China is provided. We suggest that the two new species are likely arboreal based on our collections, however, further arboreal sampling is necessary to confirm this hypothesis. We hope this study may spurn effort to generate further information on sub-tropical Chinese Temnothorax species.

Fourteen species of the subgenus Sinotipula (Diptera, Tipulidae) were previously known to occur in China. Here four species are described and illustrated as new to science: Tipula (Sinotipula) drolma sp. nov., T. (S.) forcipicauda sp. nov., T. (S.) heminga sp. nov. and T. (S.) longiloba sp. nov. The following three species are redescribed: T. (S.) exquisita Alexander, 1935, T. (S.) hobsoni Edwards, 1928 and T. (S.) wardi Edwards, 1928, and a key to the species of Tipula (Sinotipula) from China is presented. We also give a new replacement name for Tipula (Vestiplex) bucera Yang, Li, Pan, Liu & Yang, 2021, i.e., T. (V.) curvicornis nom. nov.
