In the mid-2000s, molecular phylogenetics turned into phylogenomics, a development that improved the resolution of phylogenetic trees through a dramatic reduction in stochastic error. While some then predicted “the end of incongruence”, it soon appeared that analysing large amounts of sequence data without an adequate model of sequence evolution amplifies systematic error and leads to phylogenetic artefacts. With the increasing flood of (sometimes low-quality) genomic data resulting from the rise of high-throughput sequencing, a new type of error has emerged. Termed here “data errors”, it lumps together several kinds of issues affecting the construction of phylogenomic supermatrices (e.g., sequencing and annotation errors, contaminant sequences). While easy to deal with at a single-gene scale, such errors become very difficult to avoid at the genomic scale, both because hand curating thousands of sequences is prohibitively time-consuming and because the suitable automated bioinformatics tools are still in their infancy. In this paper, we first review the pitfalls affecting the construction of supermatrices and the strategies to limit their adverse effects on phylogenomic inference. Then, after discussing the relative non-issue of missing data in supermatrices, we briefly present the approaches commonly used to reduce systematic error.

Odonata checklist from Son Tra Nature Reserve, Da Nang city, central Vietnam
Abstract: A checklist of 44 odonate species (21 Zygoptera and 23 Anisoptera) from Son Tra Nature Reserve, central Vietnam is provided. Idionyx thailandica Hämäläinen, 1985 is recorded for the Vietnamese fauna for the first time, a new Coeliccia sp. is awaiting description in the near future, and the taxonomic status of specimens of the genus Leptogomphus remains unsettled and will have to be solved in the future.
Am 3. Oktober begeht der 1969 eingeweihte Berliner Fernsehturm seinen Jahrestag. Seit einigen Jahren wird hier in dem auf 207 m Höhe gelegenen Drehrestaurant Sphere, ehemals Tele-Café, das "Einheits-Menü" aus kulinarischen Ost- und West-Spezialitäten serviert. Dass das einstige Wahrzeichen der DDR nach dem Mauerfall rasch zum Symbol des wiedervereinten Deutschlands avancierte, verdankt es nicht allein seinem heutigen Betreiber, der Deutschen Telekom, die mit eindrucksvollen Außenverkleidungen der Turmkugel zu besonderen Anlässen auch für Deutschland wirbt. Es ist die in der Tradition von Kugelbauten stehende sphärische Konstruktion selbst, die eine architektonische Vision gesellschaftlicher Einheit verkörpert.
The genus Brachypsectra LeConte, 1874 (Coleoptera: Brachypsectridae) in the Palaearctic Region
(2017)
We summarize all information regarding the genus Brachypsectra (Coleoptera: Brachypsectridae) in the Palaearctic Region. New material of B. kadleci Hájek, 2010 is reported from western and southern Iran and its intraspecific variability in coloration and morphology is described and figured. Brachypsectra jaechi sp. nov. from southern Turkey is described from males, and an unassociated Brachypsectra species from Cyprus is reported, including the descriptions of its female and larva. These findings are the first records of this genus as well as of the family Brachypsectridae for Turkey and Cyprus. Additionally, a diagnostic key to the adult males and larvae of all Brachypsectra species is updated.
A new genus is erected within the Cetoniini to describe a newly discovered species with characters shared between Heteroclita Burmeister, 1842, Ichnestoma Gory & Percheron, 1833 and Meridioclita Krikken, 1982. Neoclita pringlei gen. et sp. nov. exhibits a simple clypeal structure without specialized armour, along with hypertrophic and hairy tarsal segments as well as a fully winged female. The new species also exhibits an aedeagal structure closest to Meridioclita, with dorsal lobes of parameres substantially narrower than the ventral ones. The species appears to be restricted to high altitudes in the southwestern peri-Drakensberg area of the Eastern Cape Province, South Africa. Similarly to other mountain relicts known from the southern African region, adults emerge only after major rainfall events during the late spring to early summer season and do not show any evidence of feeding. It appears that flying activity may be temporarily interrupted following soil desiccation, to resume promptly after the next rainfall.
The genus Synaldis Foerster, 1863 is recorded in the Neotropical region for the first time. Five new Neotropical species, S. brasiliense Peris-Felipo, sp. nov., S. fritzi Peris-Felipo, sp. nov., S. longiflagellaris Peris-Felipo, sp. nov., S. magnioculis Peris-Felipo, sp. nov., and S. novateutoniae Peris-Felipo, sp. nov., are described and illustrated. The original combination for Synaldis ulmicola Ashmead, 188
A new species of the Andean stag beetle genus Auxicerus Waterhouse, 1883 is described from the humid Tucuman-Bolivian forest in the southern Bolivian Andes. Auxicerus magnipunctatus sp. nov. is distinguished from all congeners by the distinctly larger punctures of the mesosternum; antennomeres 2–6 subquadrate, last two joints of club wider than long; lamellae not widely separated; posterior end of ocular canthus rounded and anterior edge of canthus moderately developed into an obtuse triangle. Auxicerus magnipunctatus sp. nov. is possibly endemic to the Tucuman-Bolivian forest. Along with the presence of other endemic beetle species with tropical congeners, the discovery of A. magnipunctatus sp. nov. supports the idea that the persistence of rather tropical taxa in the subtropical realm is fostered by increased humidity at orographic rain barriers and climatic stability in the Tucuman-Bolivian forest.
Six species of Anastatus Motschulsky, 1859 (Hymenoptera: Eupelmidae) were described from China in Chinese by J.K. Sheng and coauthors in 1997 and 1998: A. dexingensis, A. flavipes, A. fulloi, A. huangi, A. meilingensis and A. shichengensis. This represents almost half the species of Anastatus recorded from China, but no keys were given to differentiate the species and the original descriptions included only simple line drawings to illustrate the species. Because recognition of these species is critical prior to clarifying the Anastatus fauna of China and of the eastern Palaearctic and Oriental regions, we have redescribed the six species in detail in English based on original type material, illustrating the species through macrophotography of type material and providing a key to differentiate females of the species.
This paper describes and illustrates a new genus and a new species belonging to the family Nesticidae based on morphology and supported by molecular data. The new genus, Kryptonesticus gen. nov., groups eight species spread from Bulgaria and Turkey to Croatia, including Montenegro, Bosnia and Herzegovina and Crete. As a result, seven new combinations are proposed: K. eremita (Simon, 1879) comb. nov., K. arenstorffi (Kulczyński, 1914) comb. nov., K. fagei (Kratochvíl, 1933) comb. nov., K. beroni (Deltshev, 1977) comb. nov., K. beshkovi (Deltshev, 1979) comb. nov., K. henderickxi (Bosselaers, 1998) comb. nov. and K. dimensis (López-Pancorbo, Kunt & Ribera, 2013) comb. nov., all ex Nesticus. Kryptonesticus deelemanae gen. et sp. nov. is described on the basis of both sexes and its phylogenetic relationships with closely related species are discussed based on morphological and molecular data (the cox1, rrn and H3 genes). In addition, the species of this new genus (except for K. eremita) are clear candidates for protection: they have highly restricted ranges and some of them show a high degree of adaptation to the subterranean environment.
This paper revises the genus Ganelius Benesh, which is endemic to Madagascar, in the stag beetle tribe Figulini Burmeister (Coleoptera: Lucanidae: Lucaninae). Species in the genus are striking in their highly sexually dimorphic mandibles, a character that rarely occurs in the tribe. The genus was previously comprised of four species, but three of these names were problematic or questionably applied. A lectotype is designated for G. madagascariensis Laporte, a neotype is designated for Ganelius oberndorferi Nonfried, and Nigidius passaliformis Benesh is newly synonymized with G. oberndorferi. Two new species, G. gnamptus Paulsen and G. zombi Paulsen, are described from western Madagascar. The identity of the overlooked Ganelius nageli (Kriesche) is fixed through a neotype designation, and the species is moved to the new genus Agnelius, which is distinguished from Ganelius by a lack of sexual dimorphism, serrate protibiae, and a more flattened body.
Als der jiddische Dichter Abraham Sutzkever 1943 im Ghetto von Wilna sein Gedicht "unter dayne vayse shtern" ("Unter deinen weißen Sternen") schrieb, hatte er bereits die Ermordung der Hälfte aller jüdischen Einwohner der litauischen Hauptstadt, darunter seine Mutter und sein neugeborenes Kind, erlebt. Er selbst überlebte die Vernichtung zunächst in der durch die Deutschen besetzten Stadt - bis dahin auch "Yerushalyim de Lite" genannt -, dann im Ghetto und später als Partisan in den Naroczer Wäldern, von wo aus er noch während des Krieges nach Moskau gelangte. Nachdem er bei den Nürnberger Prozessen als Zeuge ausgesagt hatte, emigrierte er schließlich 1947 über Polen und Frankreich nach Erez Israel, wo er bis zu seinem Tod 2010 lebte und schrieb. So wendungsreich sein Lebensweg war, so vielschichtig sind seine lyrischen Texte. Immer neu kreisen sie um das Gedenken an die Ermordeten und versuchen, dem drohenden Abbruch jüdischer Gedächtnisgenealogie zu begegnen. [...] Sutzkevers bekannteste Ghetto-Dichtung, vertont von Avrom Brudno und vermutlich uraufgeführt in einer Revue des Ghetto-Theaters, thematisiert das Rätsel des verborgenen göttlichen Antlitzes.
New state records for 49 species of Eucnemidae (Coleoptera) are reported throughout the United States and a single species is newly reported from Utah. Diagnostic remarks are offered for Xylophilus crassicornis Muona and distributional observations are discussed for Dirrhagofarsus lewisi. The importance of retaining by-catch from statewide, regional, and national surveys for future studies is also discussed.
A primitive subfamily of false click beetles (Coleoptera: Eucnemidae: Phlegoninae) distributed primarily in the Neotropical region is revised. Euryphlegon gen. nov. is described from Belize in Central America. New species include: Phlegon chiriquiensis sp. nov. (Panama), Phlegon panamensis sp. nov. (Panama), Euryphlegon jacqueschassaini sp. nov. (Panama) and Euryphlegon parallelus sp. nov. (Belize). Phlegon herculeanus (Lacordaire) stat. res. is resurrected from synonymy with Phlegon buqueti Laporte. One new combination is proposed: Euryphlegon degallieri (Muona) (Phlegon). Based on a number of observed external character traits, Euryphlegon is placed in Orodotini Muona, 1993 within Macraulacinae Fleutiaux, 1922. Identifi cation keys are provided for species of Phlegon and Euryphlegon in the Neotropical region. The relationships among Phlegon, Euryphlegon, Euryptychus LeConte and other groups within Echthrogasterini Cobos, 1964 and Orodotini are discussed.
Six new species of false click beetle (Coleoptera: Eucnemidae) are described. These new species are: Fornax dixiensis sp. nov. (Florida, USA), Dromaeolus comayaguiensis sp. nov. (Honduras), Asiocnemis bicolor sp. nov. (Ecuador), Miruantennus chinensis sp. nov. (Yunnan prov., China), Miruantennus cuneiformis sp. nov. (Malaysia) and Nematodes africanus sp. nov. (Côte d’Ivoire). Identifi cation keys are provided for species of Fornax in the Nearctic ecozone and Miruantennus in the Palearctic and Indo-Malayan ecozones. A new key to include all the genera within the tribe Nematodini Leiler is also provided.
Descriptions and illustrations of the triungulin, 5th instar, and prepupal larval forms for Nematodes penetrans (LeConte, 1852) (Coleoptera: Eucnemidae: Macraulacinae: Nematodini) are given. The descriptions are based on triungulins collected in a plastic vial as well as 5th instars and prepupal larval stages collected from hard sections of sugar maple (Acer saccharum Marshall; Aceraceae) logs and limbs. Adults were reared from those pieces placed in plastic bags. Biological information is provided, based on literature search and personal observations.
Comparative studies between larvae of N. penetrans and the European species, Nematodes fi lum (Fabricius, 1801) along with other Nearctic larval forms are briefl y discussed. This discovery represents the fi rst larval description for the genus in the Nearctic region.
The New World genus Chariessa Forster (Coleoptera: Cleroidea: Cleridae) is revised and includes C. catalina Opitz, new species, C. elegans Horn, C. dichroa (LeConte), C. floridana Schaeffer, C. pilosa (Forster), C. texana Wolcott, C. ramicornis Perty, C. vestita (Chevrolat), and C. duponti (Spinola). Enoplium pilosa var. marginata Say is synonymized with Chariessa pilosa Forster. Lectotypes are designated for C. pilosa (Forster), C. ramicornis Perty, and C. vestita (Chevrolat). Available information indicates that Chariessa adult and immature individuals are predatory on lignicolous insects with a particular affinity for cerambycids and buprestids that infest species of oak. It is postulated that Pleistocene speciation generated the North American components of Chariessa with more ancient southern species generated during the Middle Tertiary; after closures of the Middle American portals and orogeny of the South American Andes. Included in this treatise is a discussion of natural history, key to species, narratives of zoogeography and phylogeny, one diagram of a phylogenetic tree, 35 line drawings, eight SEM micrographs, twelve habitus photographs, nine photographs of male genitalia, and five distributional maps.
A new species belonging to the crustacean class Remipedia is described from an anchialine cave system on the island of Cozumel (Mexico), and is illustrated and compared morphologically and molecularly (CO1 and 16S) with closely related taxa. Xibalbanus cozumelensis sp. nov., the first remipede described from Cozumel, is morphologically similar to Xibalbanus tulumensis (Yager, 1987) from the Yucatán Peninsula, but the two species are genetically separate from each other (about 10% in CO1). A phylogenetic (Bayesian) analysis of Yucatán remipede populations based on CO1 and 16S placed them in a monophyletic Xibalbanus (in Xibalbanidae fam. nov.), with X. cozumelensis as most closely related to X. tulumensis. The Yucatán Peninsula and Cozumel have been separate since approx. early Cenozoic (~65 Ma), which suggests allopatric speciation for X. cozumelensis sp. nov. and X. tulumensis. However, the comparatively low genetic divergence between the two species may indicate that there has been gene flow between ‘mainland’ Yucatán and Cozumel long after the geological separation of the two landmasses, e.g., in cave systems under the sea bed, either continuously or sporadically, for example during the Last Glacial Maximum when the sea level was about 120 m lower than today.
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.
The genus Oxidus Cook, 1911 is revised to contain five species, O. avia (Verhoeff, 1937), O. gigas (Attems, 1953), O. gracilis (C.L. Koch, 1847), O. riukiaria (Verhoeff, 1940), and “species inquirenda” O. obtusus (Takakuwa, 1942). A cosmopolitan species, O. gracilis, is widely found in temperate and sub-tropical regions over the world, but other species have limited distribution in restricted regions, e.g., O. gigas in northern Vietnam, O. riukiaria and O. avia in the Ryukyu Islands (Japan). Four species, O. gracilis, O. riukiaria, O. avia and O. gigas, are confirmed as different from each other in gonopod characters, coloration and body size. The status of the last species, O. obtusus, is still doubtful and requires examination of further fresh material. The phylogenetic relationships among species of Oxidus is analyzed using two fragments of the mitochondrial genes COI (Cytochrome c Oxidase subunit I) and 16S rRNA. Three species of Oxidus are clearly separated from each other; O. gigas and O. gracilis form a monophyletic sister group with O. riukiaria. The genus Oxidus is also monophyletic and more closely related to the genus Tylopus Jeekel, 1968 than to the genera Sellanucheza Enghoff, Golovatch & Nguyen, 2004 or Kronopolites Attems, 1914. In addition, an identification key to species of Oxidus is provided.
