While many programs are available to edit phylogenetic trees, associating pictures with branch tips in an efficient and automatic way is not an available option. Here, we present TreePics, a standalone software that uses a web browser to visualize phylogenetic trees in Newick format and that associates pictures (typically, pictures of the voucher specimens) to the tip of each branch. Pictures are visualized as thumbnails and can be enlarged by a mouse rollover. Further, several pictures are can be selected and displayed in a separate window for visual comparison. TreePics works either online or in a full standalone version, where it can display trees with several thousands of pictures (depending on the memory available). We argue that TreePics can be particularly useful in a preliminary stage of research, such as to quickly detect conflicts between a DNA-based phylogenetic tree and morphological variation, that may be due to contamination that needs to be removed prior to final analyses, or the presence of species complexes.
Two new genera and species of tiger beetles from Baltic amber (Coleoptera: Carabidae: Cicindelinae)
(2017)
Two fossil tiger beetle species (Coleoptera, Carabidae, Cicindelinae) are described from Eocene Baltic amber using light microscopic and X-ray microscopic techniques. Both species are considered representatives of the subtribe Iresina Rivalier, 1971 due to the shared combination of character states: glabrous head, six labral and four suborbital setae, and glabrous pronotum. Palaeopronyssiformia groehni Wiesner, Will, and Schmidt, new genus, new species, is characterized by a glabrous and furrowed head with six labral setae, large eyes, presence of two supraorbital setae on each side, mandibles with two teeth of the incisor region, and a glabrous and furrowed pronotum. Palaeoiresina cassolai Wiesner, Will, and Schmidt, new genus, new species, is characterized by a unicolored, undentated labrum, mandibles with two teeth of the incisor region, glabrous head with six labral setae, two clypeal setae, two supraorbital setae on each side, and a glabrous pronotum, mesepisternum, mesepimeron, and metepisternum. The species described here represent the only known tiger beetle fossils preserved in Baltic amber.
Samples from deep benthic areas in the Bransfield Strait, Antarctica, revealed the presence of two new species of Colletteidae: Filitanais elongatus sp. nov. and Macrinella lavradoae sp. nov. Filitanais elongatus sp. nov. resembles F. moskalevi in its habitus; it can, however, be distinguished by characters such as the pleonites and pleotelson with lateral margins parallel and the uropod exopod being longer than half of the first endopod article. Macrinella lavradoae sp. nov. differs from the other species of Macrinella in the shape of the uropod and the pleotelson, with the uropod exopod shorter than the first article of the endopod, the uropod about as long as the pleotelson and the pleotelson with a rounded tip. The number of species of Tanaidacea recorded from Antarctica increases to 162, while the colletteids are now represented by 16 species. Moreover, the diagnosis of the genus Filitanais is herein modified.
Two new species of hangingflies, Terrobittacus rostratus sp. nov. and Terrobittacus angustus sp. nov., are described and illustrated from Yunnan, southwestern China, increasing the species number of Terrobittacus Tan & Hua, 2009 to six. Terrobittacus rostratus sp. nov. differs from its congeners by wings devoid of markings and epandrial appendages slightly longer than half the length of the gonocoxites. Terrobittacus angustus sp. nov. can be recognized by wing markings along R5 distally. A key to species of the genus is updated to include the two new species.
Two new species of the Rhyacophila nigrocephala species group, R. voluta sp. nov. and R. linguiformis sp. nov., are described, diagnosed and illustrated. Rhyacophila voluta sp. nov. is similar to R. pentagona Malicky & Sun, 2002 in male genitalia, but can be diagnosed by the inferior appendages of the same length as the complex of preanal appendages and dorsal lobe of segment IX, fused base of the basal segments of inferior appendages, and slightly incised distal margin of apical segment of inferior appendage. Rhyacophila linguiformis sp. nov. is similar to R. rima Sun & Yang, 1995 and R. esorima Mey, 1996 in male genitalia, but can be diagnosed by the progressively narrowed complex of preanal appendages and the dorsal lobe of segment X, the short anal sclerites, and the small gap between the upper and lower lobes of apical segment of inferior appendages. An updated checklist of 23 species recorded from China is presented.
Ufocandona hannaleeae gen. et sp. nov. (Crustacea, Ostracoda) from an artesian well in Texas, USA
(2017)
We describe a new genus, Ufocandona gen. nov. with its type species Ufocandona hannaleeae gen. et sp. nov., from an artesian well in San Marcos, Texas, USA. The new genus has diagnostic characteristics that distinguish it from other genera in Candonidae, including the asymmetric shape of the valves, the smooth central area on the external surface of the valves, the hexagonal ornamentations around the marginal ends of the carapace, the dense spines on the marginal edges of the right valve and the dorsal prolongation and tubercles seen from inside the ventral edges of the left valve. Additional differences in the soft body parts of the male and female (e.g., claw-like uropod, shape of hemipenis, long Y aesthetascs, two short or reduced exopods on antenna, reduced numbers of setae and segments on other extremities) distinguish the new genus from others in the family. The discovery of this species from a deep artesian well contributes important information to our understanding of groundwater species diversity in a biologically diverse aquifer where the ostracod fauna has been unstudied.
A new species of Autostichidae, Eraina beechei nov. sp., is described from specimens collected in the Andean mountains of Ñuble, Biobío. Diagnostic characters for the species are presented; photographs of adults, illustrations of male and female genitalia, and a key for identifi cation of Eraina species are provided.
Una nueva especie del género Eugnosta Hübner, E. lankinae n.sp. (Lepidoptera: Tortricidae), es descrita para la Provincia de Elqui, Chile. Se entregan los caracteres morfológicos del adulto y las fi guras de la genitalia masculina. Además se discute su posición sistemática con dos especies congéneres Neotropicales.
The cryptic assassin bug subfamily Physoderinae is characterized by a distinctly uneven species and genus-level diversity across continents, but the lack of a phylogeny has so far precluded investigations into the biogeographic history of the group. Endemic Madagascan Physoderinae (11 of the 15 genera) exhibit broad morphological diversity, but the large (38 spp.) and seemingly uniform genus Physoderes is widely distributed across the Oriental and Australasian regions. The three remaining genera are small or even monotypic and restricted to the Neotropical (Cryptophysoderes, Leptophysoderes) and Afrotropical (Porcelloderes) regions. To investigate relationships among Physoderinae, with emphasis on the monophyly of the Madagascan fauna and the monophyly of Physoderes, we conducted a cladistic analysis based on 57 morphological characters and complete genus-level taxon sampling. We found that the Madagascan fauna is not monophyletic, indicating that the island was colonized more than once, although the great majority of Madagascan taxa are part of a single clade. Overall relationships are recovered as Afrotropical Porcelloderes + [(Neotropical Cryptophysoderes, Leptophysoderes) + (Madagascan, Oriental and Australasian taxa)]. Physoderes is shown to be polyphyletic and 3 new genera, Breviphysoderes gen. nov., Macrophysoderes gen. nov. and Nanophysoderes gen. nov., are erected to accommodate new species and several species previously classified as Physoderes. A taxonomic revision of Physoderes and allied genera is conducted. Diagnoses, updated distribution ranges, habitus and genitalic images, and identification keys are provided. A total of 17 synonymies are given, and 15 new species and 3 new genera are described, focusing on the diversity of Physoderinae in the Oriental and Australasian regions. The new species are Breviphysoderes fulvopicta gen. et sp. nov., B. tenebrosa gen. et sp. nov., Macrophysoderes cirripilosa gen. et sp. nov., M. elongata gen. et sp. nov., M. finisterre gen. et sp. nov., M. grandis gen. et sp. nov., Paraphysoderes popeye sp. nov., Physoderes anamalaiensis sp. nov., P. brevipennis sp. nov., P. minime sp. nov., P. muluensis sp. nov., P. mysorensis sp. nov., P. nigripennis sp. nov., P. ractepilosa sp. nov. and P. tricolor sp. nov.

In shelled molluscs, assigning valid species names to independent evolutionary lineages can be a difficult task. Most original descriptions are based on empty shells and the high levels of variation in shape, color and pattern in some groups can make the shell a poor proxy for species-level identification. The deep-sea gastropod turbinid genus Bolma is one such example, where species-level identification based on shell characters alone is challenging. Here, we show that in Bolma both traditional and molecular taxonomic treatments are associated with a number of pitfalls that can lead to biased inferences about species diversity. Challenges derive from the few phylogenetically informative characters of shells, insufficient information provided in original descriptions and sampling artefacts, which at the molecular level in spatially fragmented organisms can blur distinctions between genetically divergent populations and separate species. Based on a comprehensive dataset combining molecular, morphological and distributional data, this study identified several cases of shell-morphological plasticity and convergence. Results also suggest that what was thought to be a set of distinct, range-restricted species corresponds instead to a smaller number of more widespread species. Overall, using an appropriate sampling design, including type localities, allowed us to assign available names to evolutionarily significant units.
The Odonata fauna of flat marshy areas of the Gulf of Siam coast in Koh Kong Province of Cambodia, containing 55 species, is considered. The published data of 2010- 2013 and new data of 2014 and 2016 on the surroundings of Koh Kong town are compiled and the first data on the area of large swampy Melaleuca forests at Andoung Tuek village are presented as well as some occasional photographic records. Gynacantha bayadera, Lyriothemis mortoni and Pornothemis serrata were for the first time recorded for Cambodia. Mortonagrion falcatum was found unexpectedly abundant at Andoung Tuek.
Results are presented of a brief odonatological examination of the Abrau and Taman' Peninsulas at the northwesternmost Caucasian Black Sea coast in Krasnodarskiy Kray, Russia, on July 2026, 2017. Twenty three species have been observed at the former peninsula and five at the latter. The Odonata records at the Abrau Peninsula are summarised, to include 34 species.
Vergebene Chance
(2017)
Zu leugnen gibt es schon seit über zwanzig Jahren nichts mehr. Hans Robert Jauß, der vielleicht bedeutendste, ganz sicher aber der wirkmächtigste deutsche Romanist nach 1945 war ein hoch dekoriertes Mitglied der Waffen-SS. [...] Fest steht: Jauß war nicht jener kleine und durchschnittliche 'Mitläufer', als der er aufgrund manifester Falschaussagen 1948 'entlastet' wurde, als den er sich vermutlich selbst zeit seines Lebens sah und als den einige seiner Schüler ihn bis heute sehen wollen. Jauß war bis 1945 ein militanter Faschist. [...] Mit Bezug auf seine SS-Vergangenheit lassen sich bestimmte Dimensionen des Jauß'schen Werks neu oder anders perspektivieren, aber man dringt damit kaum zu seinem epistemologischen oder ideologischen Kern vor. [...] Das Verstörende am Wissenschaftler Jauß besteht nicht darin, dass seine Texte elementar vom NS infiziert wären. Das Verstörende besteht darin, dass sie das nicht sind.

Es war nicht das erste Mal, dass der Begriff des Überlebens in die Welt des Entertainments eingeführt wurde, aber Gloria Gaynors Disco-Hit "I Will Survive" aus dem Jahr 1978 markiert doch eine Zäsur. Wie Titel, Leitmotiv und Formsprache des Songs verweist auch das Vokabular, in dem sein durchschlagender Erfolg beschrieben worden ist, auf die Aktualität eines unheimlich gewordenen Erbes. Der Beginn der modernen Geschichte, die den Konnex von Fun und Survival stiften hilft, lässt sich datieren auf Darwins Ersetzung der Bezeichnung "natural selection" durch den Ausdruck "survival of the fittest", der ihm "besser und zuweilen ebenso bequem" wie jener erschien. Dies wird für lange Zeit das letzte Mal gewesen sein, dass die Verwendung des Ausdrucks "survival" als "bequem" angesehen wurde.

Several millions frogs captured in the wild in Indonesia are sold for food yearly in French supermarkets, as deep frozen frog legs. They are commercialized as Rana macrodon, but up to 15 lookalike species might also be concerned by this trade. From December 2012 to May 2013, we bought 209 specimens of deep frozen frog legs, and identified them through a barcoding approach based on the 16S gene. Our results show that 206 out of the 209 specimens belong to Fejervarya cancrivora, two to Limnonectes macrodon and one to F. moodiei. Thus only 0.96 % of the frogs were correctly identified. Unless misclassification was intentional, it seems that Indonesian frog leg exporters are not able to discriminate between the species. The quasi absence of L. macrodon in our samples might be an indication of its rarity, confirming that its natural populations are declining rapidly, in agreement with its “vulnerable” status according to the IUCN Red List. Our results show that the genetic and morphological diversity of the frogs in trade is much higher than the genetic and morphological diversity measured so far by scientific studies. These results underline the need for large scale studies to assess the status of wild populations.
