Four species of the genus Panaspis – P. cabindae, P. wahlbergi, P. maculicollis and P. mocamedensis – are currently known from Angola. The analysis of recently collected specimens from Serra da Neve Inselberg, an isolated mountain located in northern Namibe Province, revealed unexpected taxonomic diversity in the group. Using an integrative taxonomy approach based on morphological and DNA sequence data, with both mitochondrial (16S) and nuclear (RAG-1) genes, we were able to distinguish two distinct populations, described here as two new species, Panaspis ericaesp. nov. and P. mundavambosp. nov. Both species are assumed to be endemic to the inselberg. This reinforces our notion of southwestern Angola as a hotspot of skink diversity, and highlights the urgent need for the conservation of Serra da Neve.
目前已知安哥拉有四个Panaspis属物种--P. cabindae、P. wahlbergi、P. maculicollis和P. mocamedensis。对最近从纳米贝省北部的一座孤山 Serra da Neve Inselberg 采集到的标本进行分析后，发现该类动物具有意想不到的分类多样性。利用基于线粒体（16S）和核（RAG-1）基因的形态学和 DNA 序列数据的综合分类方法，我们能够区分出两个不同的种群，在此描述为两个新种：Panaspis ericaesp.这两个物种都被认为是岛山的特有种。这加强了我们关于安哥拉西南部是石龙子多样性热点地区的观点，并强调了保护Serra da Neve的紧迫性。

There was a considerable gap of 21 years between the illustrated description of a specimen of the Sumatran Rhinoceros (Dicerorhinus sumatrensis) by William Bell in 1793 and the proposal to accept it as a named new species by Gotthelf Fischer in 1814. In the meantime some 17 authors reported the possibility that the animal should be regarded as a new species. Hitherto overlooked, the German writer Friedrich Justin Bertuch used a new name in the caption to a reproduction of Bell’s plate, as Rhinoceros bicornis Sumatricus. This was published in 1805 in a second edition of his “Bilderbuch für Kinder”, a serial magazine aimed at young people. This work has an extremely complex bibliography through many re-issues and translations, which is only partly resolved. The same name in the combination Rhinoceros Sumatricus was included by Gottlieb Tobias Wilhelm in a companion to the “Bilderbuch” available in 1808. The complicated circumstances of Bertuch’s proposal in 1805 and his unusual usage of a trinomen lead to the suggestion that his book might not be consistently binominal, making the name unavailable. The naming by Wilhelm in 1808 is straightforward and correct, hence Rhinoceros sumatricus Wilhelm, 1808 is an available name and a senior objective synonym of Rhinoceros sumatrensis G. Fischer, 1814. The International Code of Zoological Nomenclature allows the suggestion that Wilhelm’s name was a nomen oblitum (forgotten name). The various plates of the rhinoceros found in the “Bilderbuch” by Bertuch and the “Unterhaltungen aus der Naturgeschichte” are figured and explained.
从威廉-贝尔（William Bell）于 1793 年绘声绘色地描述苏门答腊犀牛（Dicerorhinus sumatrensis）标本，到戈特尔夫-费舍尔（Gotthelf Fischer）于 1814 年提议将其作为一个命名的新物种，中间相隔了 21 年之久。在此期间，约有 17 位作者报告了将该动物视为新物种的可能性。迄今为止，德国作家弗里德里希-贾斯汀-贝尔图赫（Friedrich Justin Bertuch）在贝尔图版的标题中使用了一个新名称，即苏门答腊犀牛（Rhinoceros bicornis Sumatricus）。这本书于 1805 年发表在他的 "Bilderbuch für Kinder"（一本面向青少年的连载杂志）第二版中。这部作品经过多次再版和翻译，书目极为复杂，目前只解决了部分问题。戈特利布-托比亚斯-威廉（Gottlieb Tobias Wilhelm）在 1808 年出版的 "Bilderbuch "的附录中收录了同名的苏门答腊犀牛（Rhinoceros Sumatricus）。贝尔图赫在 1805 年提出这一建议时的复杂情况以及他对三名的不寻常使用，导致有人认为他的书中可能没有一致的双名法，从而使这一名称无法使用。Wilhelm 在 1808 年的命名直接而正确，因此 Rhinoceros sumatricus Wilhelm, 1808 是一个可用的名称，也是 Rhinoceros sumatrensis G. Fischer, 1814 的高级客观异名。国际动物命名法》允许认为 Wilhelm 的名字是一个被遗忘的名字（nomen oblitum）。对贝尔图赫的《Bilderbuch》和《Unterhaltungen aus der Naturgeschichte》中的各种犀牛图版进行了标注和解释。

Discovering and handling cryptic diversity among species challenges taxonomists around the world. This is particularly true for the most diverse animal class – the insects – with cryptic diversity, apart from vast species numbers, being one of the main factors that hamper the description of new species. The biodiversity hotspot Cape Floristic Region of South Africa harbors many endemic and yet undescribed insect species, inter alia, Orthoptera. In this study, extended depth of field and 3D imagery enabled for a novel assessment of the external morphological characteristics used for defining and describing the genetically highly diverse genus Betiscoides Sjösdtedt, 1924, leading to a new definition of the genus’ characteristics as well as a revision of character traits of the known species. Two new species are described and a key to all five recognized Betiscoides species is provided. Application standards are derived to enable replicable and reliable image acquisition and measuring. These findings shall contribute to promote efforts being made to establish image based taxonomic identification for researchers worldwide. High-resolution images provide the basis to train deep learning algorithms/ tools, to detect the smallest differences in highly morphologically alike species, and to implement this knowledge in global species monitoring and conservation action to prevent further species loss.

We present a taxonomic review and systematic revision of the Eyelash Palm-Pitviper Bothriechis schlegelii (Berthold, 1846) based on examination of 400 museum specimens, a phylogeographic analysis of 818 locality records, and 80 individuals sampled for molecular characters. We find morphological and phylogenetic support for five new species of Bothriechis Peters, 1859, which we describe here based on their unique combination of molecular, meristic, hemipenial, and color pattern characteristics. They are: B. klebbaisp. nov., B. rasikusumorumsp. nov., B. khwargisp. nov., B. rahimisp. nov., and B. hussainisp. nov. Finally, we revalidate the names B. nigroadspersus (Steindachner, 1870), B. nitidus (Günther, 1859), and B. torvus (Posada Arango, 1889a), and provide a redescription of B. schlegelii.

We describe a new species of Ninia Baird & Girard, 1853 endemic to the cloud forests of northwestern Ecuador. The new species has previously been confused with N. atrata (Hallowell, 1845) and N. teresitae (Angarita-Sierra and Lynch 2017) but is genetically most closely related to a third species of Ninia endemic to the Chocoan–Tumbesian transition area of western Ecuador. We revalidate the name N. schmidti (Jan, 1862), designate a neotype, and provide a diagnosis of the taxon and a description of its hemipenial morphology based on new material. The new and revalidated species can easily be identified from one another and from other trans-Andean South American Ninia based on ventral and subcaudal scale counts, hemipenial morphology, and coloration of the supralabials, throat, and belly. Finally, we remove N. atrata from the herpetofaunal list of Ecuador.

This study aimed to investigate the pulmonate snail species in the vicinity of the cercarial dermatitis outbreak area in southern Thailand. In 2020, an outbreak of cercarial dermatitis was reported in Chana district, Songkhla Province, caused by the ruminant schistosome Schistosoma indicum and its snail intermediate host Indoplanorbis exustus . In the present study, 1,175 pulmonate snails were collected between October 2021 and October 2022 from five provinces covering 34 locations in southern Thailand. Seven pulmonate snail species were identified based on shell morphology, including Amerianna carinata , Gyraulus bakeri , G. convexiusculus , G. hubendicki , Physella acuta , Indoplanorbis exustus , and Radix rubiginosa . Among these snails, eight species, and five types of cercariae were identified, viz. type (i) Echinostome cercariae consisted of Echinoparyphium recurvatum , Echinostoma spiniferum , and E. revolutum , type (ii) Brevifurcate-apharyngeate cercariae consisted of Schistosoma indicum and S. spindale , type (iii) Brevifurcate-pharyngeate-clinostomatoid-cercariae was represented by Clinostomum giganticum , type (iv) Longifurcate–pharyngeate cercariae (strigea cercaria) was Diplostomum baeri eucaliae , and type (v) Ophthalmoxiphidiocercaria. Among the seven pulmonated snail species, three were found to be infected, viz. G. convexiusculus , I. exustus , and R. rubiginosa , with infection rates of 1.14% (2/176), 0.25% (2/802), and 4.02% (7/174), respectively.

Among these snails, eight species, and five types of cercariae were identified, viz. type (i) Echinostome cercariae consisted of Echinoparyphium recurvatum , Echinostoma spiniferum , and E. revolutum , type (ii) Brevifurcate-apharyngeate cercariae consisted of Schistosoma indicum and S. spindale , type (iii) Brevifurcate-pharyngeate-clinostomatoid-cercariae was represented by Clinostomum giganticum , type (iv) Longifurcate–pharyngeate cercariae (strigea cercaria) was Diplostomum baeri eucaliae , and type (v) Ophthalmoxiphidiocercaria. Among the seven pulmonated snail species, three were found to be infected, viz. G. convexiusculus , I. exustus , and R. rubiginosa , with infection rates of 1.14% (2/176), 0.25% (2/802), and 4.02% (7/174), respectively.","PeriodicalId":36314,"journal":{"name":"Evolutionary Systematics","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134886730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new monotypic Australian genus in the orb-weaving spider family Araneidae Clerck, 1757 is described, Venomiusgen. nov., with V. tomhardyisp. nov. as type species. Somatically, Venomiusgen. nov. is similar to the typical leaf-curling orb-weaving spiders, such as Phonognatha Simon, 1894 or Leviana Framenau & Kuntner, 2022, due to a similar elongate cylindrical abdomen and colouration; however, the genital morphology of the new genus is very different. Most unusual are the presence of two strong macrosetae on the male pedipalp tibia. Male pedipalp sclerites are complex, with diagnostic characters including the tibial macrosetae and a keeled median and a rounded basal process on the stipes. The epigyne of females is wholly covered by the scape that has a short median process. Venomius tomhardyigen. nov. et sp. nov. has been collected in southern Australia, from Tasmania to Western Australia, where it builds a circular, vertical orb-web. Spiders often hide in silk-lined hollows in branches of trees when disturbed during the day.

Another new species of Dixonius, D. fulbrightisp. nov., is described from Gia Lai Province, in the Central Highlands of Vietnam, using an integrated approach based on morphological, categorical (color pattern), and mitochondrial NADH dehydrogenase subunit 2 gene (ND2) and its flanking tRNAs data. Phylogenetic analyses recovered Dixonius fulbrightisp. nov. as closely related to D. gialaiensis from Gia Lai Province and part of a clade that includes D. minhlei, D. siamensis, and D. somchanhae. Multivariate (PCA, DAPC, and MFA) and univariate (ANOVA) analyses of 15 meristic (scale counts), six morphometric (mensural), and five categorical (color pattern and morphology) characters from 44 specimens of all eight species of Dixonius from Vietnam, Laos, and Cambodia clearly demonstrated that Dixonius fulbrightisp. nov. is statistically different and diagnostically distinct from all closely related species of Dixonius. This new species discovery highlights the underestimated gecko diversity and the importance of continued fieldwork in the Central Highlands of Vietnam.
