This study focuses on the Brazilian species of the genus Purenleon Stange (Neuroptera: Myrmeleontidae). A total of five species are herein reported to Brazil: Purenleon clavatus (Navás), Purenleon fernandezi Miller & Stange (first record for Brazil), Purenleon cautus (Walker) comb. n., and two new species: Purenleon limeirai sp. n. and Purenleon rafaeli sp. n. The taxonomical status of other two species was reevaluated: Formicaleo bipunctatus Navás was synonymized under P. cautus and Feinerus nebulosus Navás was revalidated and transferred to Purenleon. A key to the South American species of Purenleon is also presented.

Nine new species of the collembolan genus Salina MacGillivray from South America are described and illustrated. Two Neotropical species were recorded for the first time from Brazil: S. dedoris Mari-Mutt and S. tristani Denis. Salina was previously known to occur in three Brazilian states, and this is now updated to include 19 states with 12 recorded species. A new proposal of morphological character description and illustration, and an identification key for the celebensis group are provided. A hypothesis for the phylogenetic relationships among 34 species of Salina (about 50% of the 72 described species) allowed three main pursuits: (a) a reevaluation of Salina species groups; (b) the first explicit interpretation of how morphological characters of these springtails may have changed during the course of the diversification of the taxon; and (c) an evaluation of the historical biogeographic connections of Salina, with an emphasis on the celebensis group distribution to the New World.

The tribe Sisyphini sensu stricto comprises only three genera, the widespread Sisyphus and Neosisyphus , and the Mauritius endemic, Nesosisyphus . In southern Africa, Sisyphus and Neosisyphus are represented by five species groups in each genus. Together, they comprise a total of 33 valid species, of which six are new: Sisyphus auricomus sp. n; Sisyphus australis sp. n ; Sisyphus bicuariensis sp. n; Sisyphus inconspicuus sp. n; Sisyphus swazi sp. n; and Neosisyphus tembyi sp. n. A further Southern African species, Sisyphus crispatus , is proposed as a nomen dubium. Sisyphus natalensis (syn. n), and Sisyphus bornemisszanus (pars) (syn. n) are made synonyms of Sisyphus sordidus . Lectotypes and paralectotypes are designated for Sisyphus costatus (); Sisyphus seminulum ; Sisyphus nanniscus ; Sisyphus transvaalensis ; Neosisyphus spinipes () and Neosisyphus barbarossa (). Diagnoses, photographs of habitus and male genitalia, lists of examined material and distribution maps are presented for all species. An identification key to the southern African sisyphine species is provided.

Mantellid frogs present an extensive adaptive radiation endemic to Madagascar and Comoros, being the subfamily Mantellinae the most morphologically and ecologically diverse. The Mantellinae present key innovative evolutionary traits linked to their unique reproductive behavior, including the presence of femoral glands and a derived vomeronasal organ. In addition, previous studies pointed to size differentiation in playing an important role in species’ dispersal capacities and shaping of their geographic ranges. Despite the high phenotypic variation observed in this clade, to date an exhaustive morphological analysis of their anatomy has still not been performed, much less in relation to internal structures. Here, we present a comprehensive skeletal description of a mantellid species, Blommersia transmarina, from the island of Mayotte in the Indian Ocean, which has potentially undergone a process of moderate gigantism compared to other Blommersia species. We describe its intraspecific skeletal variation utilizing non-destructive volume renderings from μCT-scans, and characterize the presence of sexual dimorphism and size covariation in skeletal structures. Notably, we found numerous signs of hyperossification, a novel structure for mantellids: the clavicular process, and the presence of several appendicular sesamoids. Our findings suggest that skeletal phenotypic variation in this genus may be linked to biomechanical function for reproduction and locomotion.

The connectivity of groundwater aquifers is lower compared to surface waters. Consequently, groundwater species are expected to have smaller distributional ranges than their surface relatives. Molecular taxonomy, however, unveiled that many species comprise complexes of morphologically cryptic species, with geographically restricted distributional ranges in subterranean as well as in surface waters. Hence, the range sizes of surface and groundwater species might be more similar in size than hitherto thought. We tested this hypothesis by comparing the range size of surface amphipods of the genus Gammarus and subterranean amphipods of the genus Niphargus in Iran. We re-analyzed the taxonomic structure of both genera using two unilocus species delimitation methods applied to a fragment of the COI mitochondrial marker, to identify molecular operational taxonomic units (MOTUs), and assessed the maximum linear extent (MLE) of the ranges of MOTUs from both genera. Genus Gammarus comprised 44–58 MOTUs while genus Niphargus comprised 20–22 MOTUs. The MLEs of the two genera were not significantly different, regardless the delimitation method applied. The results remained unchanged also after exclusion of single site MOTUs. We tentatively conclude that in this case there is no evidence to consider that groundwater species are geographically more restricted than surface species.

The putative monophyly and systematic position of Merodon nigritarsis group was assessed based on morphological and molecular data of the mitochondrial COI and nuclear 28S rRNA genes. The previously reported concept of the group has been redefined, and M. crassifemoris Paramonov, 1925 is now excluded. The related M. avidus group is redefined here, including the Merodon avidus complex and M. femoratus Sack, 1913. Species delimitation of morphologically defined species of M. nigritarsis group was well supported by COI gene analysis, with the exception of M. alagoezicus Paramonov, 1925 and M. lucasi . Descriptions are given for three new species of the M. nigritarsis species group: Merodon cohurnus Vujić, Likov et Radenković sp. n., Merodon longisetus Vujić, Radenković et Likov sp. n. and Merodon obstipus Vujić, Radenković et Likov sp. n., and one new species from the M. avidus group: Merodon rutitarsis Likov, Vujić et Radenković sp. n. A lectotype is designated for M. femoratus Sack, 1913, and two new synonymies of this species were proposed: M. biarcuatus Curran, 1939 and M. elegans . Here we review 18 species from the M. nigritarsis group and six species from the M. avidus group and provide morphological diagnoses of the species groups. Additionally, diagnosis of 12 branches (groups or individual taxa) of M. avidus-nigritarsis lineage, an illustrated diagnostic key for the males, and distribution map are provided for the new species.

This volume of the Chinese Research Perspectives on the Environment series is a translation of Environmental Security in China, which features contributions from top researchers from Chinese universities, including the Chinese Academy of Social Sciences. The ten articles following the introduction cover a range of environmental issues in four large categories with significant security implications: pollution, ecosystem deterioration, food and energy supply. In addition to long-standing environmental problems such as air, water and soil pollution, and grassland degradation, genetically modified (GM) foods, climate change and China’s energy dependence, which have taken on increasing urgency in recent years, are also discussed. Each chapter includes conceptual clarifications, historical overview, empirical analysis, case studies, international comparisons, and policy recommendations.
Paintings, Drawings and Prints up to the Nineteenth Century
Authors: Sam Segal and Klara Alen
This richly illustrated book provides an overview of all known Dutch and Flemish artists up to the nineteenth century who painted or drew flower pieces, or else made prints of them. Unlike many mainstream art historical studies, the book takes a truly comprehensive approach, including cases where only a single example is known or even if nothing of the artist’s other work appears to have survived. Containing highly instructive lists identifying the names of flowers, as well as insects and other animals, the book also discusses the earliest depictions of flower still life and the distinctive characteristics behind the development of floral arrangements in different periods, including the variation of the flowers, the variety of techniques used by artists, as well as an exploration of the symbolism behind the numerous plant and animal species this form of art portrays.

Composed in Dutch, the text was translated into English by Judith Deitch and edited by Philip Kelleway.

This book is the first comprehensive work on oriental Notodontidae (Lepidoptera) outside mainland Asia. The studied area includes also Borneo Island, the Malayan Peninsula, entire New Guinea with adjacent islands. All species are illustrated in both sexes with a total number of 1272 specimens on 51 colour plates. Genitalia photos of both sexes as well as detailed distribution maps are provided for each species.
The book deals in the first volume with 298 species and contains descriptions of 99 new notodontid taxa. A second volume will treat with the remaining 160 species and include also a comprehensive biogeographic analysis.

Brief periods of repetitive stimulation (click trains) presented either contiguous or simultaneous to an interval have been previously shown to impact on its perceived duration. In the current investigation we asked whether the perception of temporal order can be altered in a similar way. Participants completed a dichotic spectral temporal order judgement task with the stimuli titrated to their individual thresholds. Immediately prior to the judgement, participants were presented with five seconds of click trains, white noise or silence. We extended previous work on this topic by using each participant’s accuracy and response time data to estimate diffusion model parameters so that the cognitive mechanisms underlying any effect of click trains on the response could be disentangled. There was no effect of stimulation condition on participant’s accuracy, or diffusion model parameters (drift rate, boundary separation or non-decision time). The present findings therefore suggest that click trains do not influence temporal order perception. Additionally, the previous suggestion that click trains induce an increase in the rate of information processing was not supported for this temporal order task. Further work probing the limits and conditions of the click train effect will help to constrain and extend theoretical accounts of subjective timing.
