The ant subfamilies Ponerinae,Cerapachyinae, and Pseudomyrmecinae (Hymenoptera,Formicidae) in the Late Eocene ambers of Europe

The ant subfamilies Ponerinae, Cerapachyinae and Pseudomyrmecinae are revised in the Baltic, Bitterfeld, Rovno, and Scandinavian ambers of the Late Eocene age. Thirteen new species are described: Amblyopone groehni sp. n., A. electrina sp. n., Pachycondyla conservata sp. n., P. tristis sp. n., Ponera lobulifera sp. n., P. mayri sp. n., P. wheeleri sp. n., Gnamptogenys rohdendorfi sp. n., Bradoponera similis sp. n., Proceratium eocenicum sp. n. (Ponerinae), Procerapachys sulcatus sp. n. (Cerapachyinae), Tetraponera europaea sp. n., and T. groehni sp. n. (Pseudomyrmecinae). Tetraponera angustata (Mayr) is synonymized with T. simplex (Mayr). Keys to species are provided.     

A new Veturius (Veturius) of the “cephalotes” group from southern Colombia,Putumayo (Coleoptera: Passalidae)

A new species of Veturius (Veturius) Kaup from southern Colombia, Putumayo, lowland forests, is described and illustrated. V. paya n. sp. belongs to the South American “cephalotes” species group and is sister species of V. cephalotes (Le Peletier & Serville, 1825). Both species are distinguished by few characters of the head and thorax. They seem to be allopatric close to the western distributional limits of V. cephalotes. The endemism of V. paya n. sp. corresponds to a geographic vicariance in the axis of the Amazon Basin. An overview is given on the phylogeny and the chorology of the completed “cephalotes” species group.     

Preliminary notes on the genus Aeschnosoma Selys 1870 (Odonata: Anisoptera: Corduliidae s. str.)

Three new species of the genus Aeschnosoma are briefly described and illustrated. A. pseudoforcipula n. sp. and A. heliophila n. sp., both from the Brazilian Central Plateau are respectively related to the two Amazonian species A. forcipula Hagen in Selys 1871, and A. auripennis Geijskes 1970. A. louissiriusi n. sp. from Northern Brazil is not closely related to any known species. Based on larval and adult derived characters, the genus Aeschnosoma appears closely related to the Australian genus Pentathemis Karsch 1890, and also to the Madagascan genus Libellulosoma Martin 1907. The clade Aeschnosomata nov. is erected to receive the three genera. Some putative plesiomorphies would place this clade sister group of the remaining Corduliidae s.str.     

A revision of the Chinese Catops Paykull 1798 of the Catops fuscus species group (Coleoptera: Leiodidae: Cholevinae)

Five species of the Catops fuscus species group are reported from China. Three species are newly described: C. hlisnikovskyi n. sp. from the Beijing municipality and Jiangsu province, C. schuelkei n. sp. from Sichuan and Yunnan provinces, and C. smetanai n. sp. from Sichuan and Yunnan provinces. Female of C. sasajii Nishikawa 2007 is described and the species is reported from Hubei, Sichuan and Yunnan provinces for the first time. Catops nigricans (Spence 1813) is reported for the first time from China (Xinjiang Uygur autonomous region). Important morphological characters are illustrated and the distribution of all species in China is mapped. Preliminar phylogenetic analysis separates (C. hlisnikovskyi n. sp.+C. fuscus fuscus Panzer 1794) as a sister clade to C. nigricans+(C. sasajii+(C. schuelkei n. sp.+C. smetanai n. sp.)), with C. paramericanus Peck & Cook 2002 as outgroup.     

Beetles with ‘trochantelli’: phylogeny of Cephenniini (Coleoptera: Staphylinidae: Scydmaeninae) focussing on Neotropical genera

Neotropical genera of Cephenniini characterized by an additional leg ‘segment’ (‘trochantellus’) are revised, and the following new taxa are described: Shyri gen.n. , Shyri pichincha sp.n. (type species of Shyri) (Ecuador), Shyri perversus sp.n. (Ecuador), Shyri quitu sp.n. (Ecuador), Shyri microphthalmus sp.n. (Ecuador), Monstrophennium gen.n. (type species: Cephennium spinicolle Schaufuss), Furcodes gen.n. , Furcodes apicalis sp.n. (type species of Furcodes) (Mexico), Furcodes tutule sp.n. (Honduras), Paracephennium pumilio sp.n. (Costa Rica), Pseudocephennium iwokramanum sp.n. (Guyana), Pseudocephennium trilineatum sp.n. (Guyana), Pseudocephennium araguanum sp.n. (Venezuela), Pseudocephennium maximum sp.n. (Venezuela), Pseudocephennium peruvianum sp.n. (Peru), Pseudocephennium cochabambanum sp.n. (Bolivia), Pseudocephennium saramaccanum sp.n. (Suriname) and Pseudocephennium brokopondonum sp.n. (Suriname). Pseudocephennium spinicolle (Schaufuss) is transferred to Monstrophennium. Cladistic analysis of characters from adult morphology of all genera of Cephenniini and a large outgroup sample from Cyrtoscydmini, Eutheiini, Scydmaenini, Clidicini and Mastigini strongly supported the monophyly of Cephenniini. However, only the Cephennomicrus group comprising nine genera was strongly supported as a monophyletic clade, while only weak support was found for the previously suggested Cephennodes group and Cephennium group. Two alternative hypotheses concerning the phylogeny of Cephenniini are put forward and discussed: (i) the Cephennium group is sister to all remaining Cephenniini; or (ii) the Cephennomicrus group is sister to all remaining Cephenniini. The Neotropical genera with ‘trochantellus’ form a well‐supported clade derived from the ancestral lineage of the Cephennodes group.     

Systematic revision,molecular phylogeny and biogeography of the antlion tribe Acanthoplectrini (Neuroptera: Myrmeleontidae: Dendroleontinae), with emphasis on the Oriental lineage

The tribe Acanthoplectrini (Myrmeleontidae: Dendroleontinae) includes a group of antlion genera widely distributed across the Australasian and Oriental regions. The intergeneric and interspecific relationships between or within the Australian and Oriental lineages of this tribe as well as their historical biogeography remain largely unexplored. Here, we present a molecular phylogenetic and biogeographic analyses of Acanthoplectrini to infer the diversification history of this tribe, with emphasis on the Oriental lineage. Both the Oriental and Australian lineages are monophyletic and recovered as sister groups. Ancestral area reconstruction suggests that the ancestor of Acanthoplectrini might have been once widely distributed from Indochina to Australia and then split into the Oriental and Australian lineages during the early-Miocene. Our analyses recovered northeastern Indochina and south China as the ancestral range of the Oriental Acanthoplectrini. During the mid-Miocene to the mid-Pliocene, orographic events such as the rising of mountain ranges (including the Himalayas) and the formation of major islands in southeastern Asia triggered several dispersal and vicariance events in the Oriental Acanthoplectrini, driving their speciation. We revise the classification of the Oriental Acanthoplectrini, establishing the new genus Paralayahima gen. n. , which is recovered sister to Layahima Navás. Moreover, we describe four new species of Layahima, Layahima aspoeckorum sp. n. , Layahima monba sp. n. , Layahima lhoba sp. n. and Layahima xinliae sp. n. , and we reinstate two previously synonymized species, Layahima melanocoris (Yang) stat. rev. and comb. n. and Layahima nebulosa Navás stat. rev.     

World revision of Dolichocolon Brauer & Bergenstamm (Diptera: Tachinidae: Exoristinae: Goniini)

The Palaeotropical goniine genus Dolichocolon Brauer & Bergenstamm is revised and analysed cladistically. Seventeen new species are described from Australia (Queensland, Northern Territory), Cameroon, China, the Democratic Republic of Congo, Ethiopia, Japan, Papua New Guinea, Senegal, Thailand, Uganda, Yemen, and Zimbabwe. The following new synonymy is proposed after direct comparison of primary types: Dolichocolon klapperichi Mesnil, 1967 = Dolichocolon orientale Townsend, 1927 syn. nov. A key to the 21 known species is presented. A cladistic analysis based on 36 morphological characters provides support for the monophyly of Dolichocolon. A sister‐group relationship is indicated between Dolichocolon and Kuwanimyia Townsend, whereas Dolichocolon chiangmaiensis sp. nov. from Thailand takes a position as sister group to all other Dolichocolon species. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 162 , 544–584.     

Two New Diophrys‐Like Genera and Their Type Species,Apodiophrys ovalis n. g., n. sp. and Heterodiophrys zhui n. g., n. sp. (Ciliophora: Euplotida), with Notes on Their Molecular Phylogeny

ABSTRACT. Based on both morphological and molecular information, two new euplotid genera Apodiophrys n. g. and Heterodiophrys n. g. are described in the present paper. Apodiophrys n. g. is defined as sculptured Diophryinae with bipartite adoral zone; frontoventral cirri arranged in Diophrys‐pattern; marginal cirri located in two clearly separated groups. Heterodiophrys n. g. is recognizable by the combination of Diophrys‐like frontoventral cirri and the unique structure of several marginal cirri that are arranged in a long row. The type species for both new genera, Apodiophrys ovalis n. sp. and Heterodiophrys zhui n. sp., collected from southern China sea, are described. The small subunit rRNA (SSU rRNA) gene sequences for both new taxa are determined. Phylogenetic analyses based on these data indicate that Apodiophrys is most closely related to Paradiophrys, which then clusters with Uronychia species. Thus, Apodiophrys–Paradiophrys is separated from other typical Diophrys‐like genera in the SSU rRNA gene trees. The new genus Heterodiophrys is basal to the sister group of Diophrys–Diophryopsis, hence belongs to the “core”Diophrys‐complex.     

A phylogeny of Pacific fiddler crabs of the subgenus Minuca (Crustacea,Brachyura, Ocypodidae: Uca) with the description of a new species from a tropical gulf in Pacific Costa Rica

The phylogeny of all Pacific fiddler crab representatives of the subgenus Minuca Bott, 1954 (sensu Beinlich and von Hagen, 2006) is reconstructed. For the molecular analysis, Cox1 mitochondrial and 28S ribosomal nuclear DNA sequences were used. According to these data, same transisthmian sister species relationships are confirmed and a new species of the genus Uca Leach, 1814, Uca osa sp. n., is described from Golfo Dulce, a tropical gulf in Pacific Costa Rica. Morphological as well as molecular data confirm distinctness of this species compared with all other members of the subgenus Minuca, to which it belongs. Distinctive morphological traits are presented to distinguish Uca osa sp. n. from its congeners in the Eastern Pacific.     

Evolutionary morphology of whip spiders: towards a phylogenetic system (Chelicerata: Arachnida: Amblypygi)*

The aim of this study is to present a cladogram and phylogenetic system and to use this to discuss the phylogeny and biogeography of the Amblypygi. A total of 29 morphological structures were studied, their plesiomorphic and apomorphic characters or character states were identified, and the resulting data matrix was analysed. As a result, the ‘old’Charontidae or Pulvillata emerge as a paraphyletic group; the genus Paracharon is the sister group of all other amblypygids, which are now termed Euamblypygi. The ‘new’Charontidae (sensu Quintero: the genera Stygophrynus and Charon) are the sister group of the Phrynida or Apulvillata; together they form the Neoamblypygi. The relationships of the genera of the Charinidae cannot be resolved with the available data. They may be a paraphyletic group. The genus Catageus is a possible candidate for being the sister group of the Neoamblypygi. The new system allows a discussion of the phylogeny and biogeography of whip spiders. It also points to unresolved taxa and thus indicates the questions future research should address.     

Molecular systematics of the suborder Trogiomorpha (Insecta: Psocodea: 'Psocoptera')

Phylogenetic relationships among extant families in the suborder Trogiomorpha (Insecta: Psocodea: 'Psocoptera') were inferred from partial sequences of the nuclear 18S rDNA and Histone 3 and mitochondrial 16S rDNA genes. Analyses of these data produced trees that largely supported the traditional classification; however, monophyly of the infraorder Psocathropetae (= Psyllipsocidae + Prionoglarididae) was not recovered. Instead, the family Psyllipsocidae was recovered as the sister taxon to the infraorder Atropetae (= Lepidopsocidae + Trogiidae + Psoquillidae), and the Prionoglarididae was recovered as sister to all other families in the suborder. Character states previously used to diagnose Psocathropetae are shown to be plesiomorphic. The sister group relationship between Psyllipsocidae and Atropetae was supported by two morphological apomorphies: the presence of a paraproctal anal spine and an anteriorly opened phallosome. Based on these sequence data and morphological observations, we propose a new classification scheme for the Trogiomorpha as follows: infraorder Prionoglaridetae (Prionoglarididae), infraorder Psyllipsocetae (Psyllipsocidae), infraorder Atropetae (Lepidopsocidae, Trogiidae, Psoquillidae).  © 2006 The Linnean Society of London, Zoological Journal of the Linnean Society , 2006, 146 , 287–299.     

A new cavefish of Sinocyclocheilus (Teleostei: Cypriniformes: Cyprinidae) from the Nanpanjiang River in Guizhou,China

A new species, Sinocyclocheilus xingyiensis, is described based on specimens collected from a karst cave in Guizhou Province, China. The authors used an integrated taxonomic approach, including morphological and molecular data, to identify the new species as a member of the Sinocyclocheilu angularis group, and it can be distinguished from all other members of this group by a combination of the following features: two pairs of long barbels and long pectoral fins, 42–46 lateral-line scales, 7 (13–14) on outer (inner) side of the first gill arch and 35 (14–15 + 4 + 16 − 17) vertebrae. Phylogenetic analyses based on the cytochrome b (cyt b) gene fragment suggest that S. xingyiensis is a sister lineage to Sinocyclocheilus flexuosdorsalis. The genetic distance (Kimura 2-parameter) between the S. xingyiensis and S. angularis groups of Sinocyclocheilus species based on cyt b gene fragment ranged from 1.2% to 15.4%.     

Folsomia (Collembola: Isotomidae) of China. II. heterocellata group

An annotated list of species of the Folsomia heterocellata group recorded in China is given. Folsomia cephalota n. sp., F. dorsomediaseta n. sp., F. longiseta n. sp., F. manubriopilosa n. sp., F. longdeica n. sp., and F. plenosensilla n. sp. are characterized by having a simple maxillary palp, four prelabral setae and no eyes. They differentiate mainly by characteristics of the furca. We report other species of the group which are recorded for the first time in China: Folsomia tianshanica Martynova, 1969, F. pseudovtorovi Potapov & Gulgenova, 2013, and F. pseudodecemoculata Stebaeva, 1971. This excludes F. wanxianensis Ji, Ding & Chen, 2007, for which we provide morphological remarks based on the type material. The group is mainly distributed in the central part of China (Chongqing, Gansu, southern part of Inner Mongolia, Ningxia and Shaanxi provinces). A key to all blind species with a simple maxillary palp is given.     

Molecules,morphology and minute hooded beetles: a phylogenetic study with implications for the evolution and classification of Corylophidae (Coleoptera: Cucujoidea)

Eight genes (nuclear: 18S, 28S, H3, CAD; mitochondrial: 12S, 16S, COI, COII) and morphology were used to infer the evolutionary history of Corylophidae, some of the smallest free‐living insects. The study included 36 corylophid exemplars, representing approximately 60% of the known generic diversity of the family and 16 cucujoid outgroup taxa. Multiple partitioning strategies, molecular datasets, combined datasets and different taxon sampling regimes using maximum likelihood and mixed‐model Bayesian inference were utilized to analyse these data. Most results were highly concordant across analyses. There was strong agreement across (i) partitioning strategies, (ii) maximum likelihood and Bayesian inference analyses of the molecular data, and (iii) Bayesian inference of the molecular data alone and Bayesian inference of the combined morphological and molecular data when all terminal taxa were included. When a strict taxon sampling protocol was employed so that only single generic exemplars were included, deep relationships were affected in the resulting phylogenetic hypotheses. Under such narrow sampling strategies, deep phylogenetic relationships were also sensitive to the choice of generic exemplars. Although it is often challenging to obtain single representatives for many taxa in higher‐level phylogenetic analyses, these results indicate the importance of using denser taxon sampling approaches even at the specific level for genera included in such studies. Molecular data alone support Anamorphinae (Endomychidae) strongly as the sister group of Corylophidae. In combined data analyses, Coccinellidae is recovered as the sister group to Corylophidae. In all analyses, Corylophidae and the subfamily Corylophinae are recovered as monophyletic. The monophyly of Periptyctinae was untested, as only a single species was included. All included corylophine tribes were recovered as monophyletic with the exception of Aenigmaticini; Aenigmaticum Matthews forms the sister group to Orthoperus Stephens and Stanus?lipiński et al. is recovered as the sister group of Sericoderus Stephens. Stanus tasmanicus?lipiński et al. is transferred to a new genus, Pseudostanus Robertson, ?lipiński & McHugh gen.n. incertae sedis. We propose a new tribe, Stanini Robertson, ?lipiński & McHugh trib.n. for Stanus bowesteadi?lipiński et al. and a new concept of Aenigmaticini sensu.n. to include only the nominate genus. Anatomical transitions associated with corylophid miniaturization are highlighted. Key phenotypic modifications and elevated rates of substitution in nuclear rRNA genes are evident in a subgroup of Corylophinae that includes the most diminutive species. Other taxonomic and evolutionary implications are discussed in light of the results.     

Comprehensive phylogeny of the Cleroidea (Coleoptera: Cucujiformia)

The first thorough molecular phylogeny of the superfamily Cleroidea, represented by 377 taxa, and the first with an emphasis on Trogossitidae, was undertaken. Maximum likelihood and Bayesian analyses were performed on a four‐gene dataset (18S, 28S, cox1, cytb) of 395 taxa (along with 18 outgroups), including all 16 currently recognized families of Cleroidea and all current and formerly recognized tribes of Trogossitidae. The superfamily as a whole received strong support in Bayesian analyses. On the basis of phylogenetic results, 18 families in Cleroidea are recognized, including three taxa elevated to family for the first time and two reinstated families. The former tribe Rentoniini (Trogossitidae: Peltinae) was strongly supported as a monophyletic group apart from the remainder of Trogossitidae, and is herein elevated to family status, Rentoniidae stat.n. Protopeltis was also found to be an isolated lineage and becomes Protopeltidae stat.n. Peltini + Larinotini were recovered as a weakly supported sister grouping; Peltini (including only Peltis) becomes Peltidae stat.rest. The trogossitid subfamily Lophocaterinae, to the exclusion of Decamerini, formed a clade which is here designated Lophocateridae stat.rest. and sensu n. The Trogossitinae tribes Calityini, Egoliini (represented by Egolia) and Larinotini were recovered apart from core Trogossitidae but showed no strong affinities to other taxa or congruence between analyses; they are here conservatively retained in Trogossitidae as Calityinae stat.rest. , Egoliinae stat.rest. and Larinotinae stat.rest. The genus Thymalus of the peltine tribe Thymalini was indicated with moderate to strong support as the sister group of the Decamerini (Trogossitidae: Lophocaterinae); together these represent Thymalidae stat.n. and sensu n. with subfamilies Decamerinae stat.rest. ( new placement ) and Thymalinae stat.n. The remainder of Trogossitinae, the tribes Trogossitini and Gymnochilini, formed a well‐supported clade which comprises the Trogossitidae: Trogossitinae sensu n. The tribe Gymnochilini syn.n. is synonymized with Trogossitini. The monotypic family Phloiophilidae was recovered, contradicting a recent placement within Trogossitidae. The melyrid lineage was recovered with moderate (maximum likelihood) to strong (Bayesian analyses) support and includes the families Phycosecidae, Rhadalidae, Mauroniscidae, Prionoceridae and Melyridae (including Dasytidae and Malachiidae). The genus Dasyrhadus is tentatively transferred from Rhadalidae to Mauroniscidae. The genus Gietella, once proposed as a distinct family but recently placed within Dasytidae, was recovered as strongly sister to Rhadalidae sensu n. , and we transfer it to that family as Gietellinae new placement . Attalomiminae (formerly Attalomimidae) syn.n. is synonymized with Melyridae: Malachiinae: Lemphini sensu n. Melyridae sensu n. includes only Dasytinae, Malachiinae and Melyrinae. Metaxina is returned to the Chaetosomatidae sensu n. , of which Metaxinidae syn.n. becomes a junior synonym. Resolution within Cleridae was generally poor, but a broadly defined Korynetinae stat rest. + Epiclininae received high support (Bayesian analyses). Outside of Trogossitidae, the main focus of this study, major rearrangements of the classification of Cleroidea were not undertaken, despite evidence indicating such changes are needed.     

A New Species of Dolichocephala,with a Key to the Species from China (Insecta: Diptera,Empididae)

Dolichocephala guangdongensis sp. n., a new aquatic dance fly (Diptera, Empididae), is described from Guangdong province in China. The relationships with its sister species are discussed. A key to the species of the genus Dolichocephala from China is presented.     

Phylogenetic relationships within the South American fish family Anostomidae (Teleostei,Ostariophysi, Characiformes)

Analysis of a morphological dataset containing 152 parsimony‐informative characters yielded the first phylogenetic reconstruction spanning the South American characiform family Anostomidae. The reconstruction included 46 ingroup species representing all anostomid genera and subgenera. Outgroup comparisons included members of the sister group to the Anostomidae (the Chilodontidae) as well as members of the families Curimatidae, Characidae, Citharinidae, Distichodontidae, Hemiodontidae, Parodontidae and Prochilodontidae. The results supported a clade containing Anostomus, Gnathodolus, Pseudanos, Sartor and Synaptolaemus (the subfamily Anostominae sensu Winterbottom) albeit with a somewhat different set of relationships among the species within these genera. Anostomus as previously recognized was found to be paraphyletic and is split herein into two monophyletic components, a restricted Anostomus and the new genus Petulanos gen. nov. , described herein. Laemolyta appeared as sister to the clade containing Anostomus, Gnathodolus, Petulanos, Pseudanos, Sartor and Synaptolaemus. Rhytiodus and Schizodon together formed a well‐supported clade that was, in turn, sister to the clade containing Anostomus, Gnathodolus, Laemolyta, Petulanos, Pseudanos, Sartor and Synaptolaemus. Anostomoides was sister to the clade formed by these nine genera. Leporinus as currently defined was not found to be monophyletic, although certain clades within that genus were supported, including the species with subterminal mouths in the former subgenus Hypomasticus which we recognize herein as a genus. Abramites nested in Leporinus, and Leporellus was found to be the most basal anostomid genus. The presence of cis‐ and trans‐Andean species in Abramites, Leporellus, Leporinus and Schizodon, all relatively basal genera, suggests that much of the diversification of anostomid species pre‐dates the uplift of the Andean Cordilleras circa 11.8 million years ago. Several important morphological shifts in anostomid evolution are illustrated and discussed, including instances of convergence and reversal. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 154 , 70–210.     

A molecular phylogeny of the checkered beetles and a description of Epiclininae a new subfamily (Coleoptera: Cleroidea: Cleridae)

We provide the first molecular phylogeny of the clerid lineage (Coleoptera: Cleridae, Thanerocleridae) within the superfamily Cleroidea to examine the two most recently proposed hypotheses of higher level classification. Phylogenetic relationships of checkered beetles were inferred from approximately ～5000 nt of both nuclear and mitochondrial rDNA (28S, 16S and 12S) and the mitochondrial protein‐coding gene COI. A worldwide sample of ～70 genera representing almost a quarter of generic diversity of the clerid lineage was included and phylogenies were reconstructed using Bayesian and Maximum Likelihood approaches. Results support the monophyly of many proposed subfamilies but were not entirely congruent with either current classification system. The subfamilial relationships within the Cleridae are resolved with support for three main lineages. Tillinae are supported as the sister group to all other subfamilies within the Cleridae, whereas Thaneroclerinae, Korynetinae and a new subfamily formally described here, Epiclininae subf.n ., form a sister group to Clerinae + Hydnocerinae.
