Diplura is a group of entognathous hexapods, often considered a sister group to insects. They play an important role in recycling organic matter in soil and subterranean terrestrial ecosystems. The Campodeidae is the most diverse family, divided into four subfamilies. The subfamily Plusiocampinae has a subterranean life-style with many species distributed in the Euro-Mediterranean area. The incertae sedis tachycampoids (“lignée Tachycampoïde”) is a group within the family Campodeidae that share with the Plusiocampinae a strong preference for subterranean habitats and several morphological characters, such as slender body shape, elongated appendages, considerable increment in the number of antennomeres and cercal articles, and complexity of sensorial structures. The present monograph provides a taxonomic revision of the subfamily Plusiocampinae and the genera belonging to the tachycampoid lineage from Europe and the Mediterranean region. It comprises detailed morphological descriptions and illustrations together with data on the habitats and distributions of 87 species, 10 subspecies and 11 affinis forms. Seven new species are described among those, namely: Plusiocampa (Plusiocampa) apollo Sendra, Giachino & Vailati sp. nov., P. (P.) chiosensis Sendra & Gasparo sp. nov., P. (P.) dublanskii Sendra & Turbanov sp. nov., P. (P.) hoffmanni Sendra & Paragamian sp. nov., P. (P.) rhea Sendra sp. nov., P. (P.) ternovensis Sendra & Borko sp. nov. and P. (Venetocampa) ferrani Sendra & Delić sp. nov.

A cladistic analysis of the Empidoidea and basal lineages of the Cyclorrhapha, based on morphological characters, confirms the monophyly of both groups as well as that of the                    Eremoneura. The resulting final trees are used to revise the classification of the Empidoidea to include the following five families: Empididae, Hybotidae, Atelestidae (including Nemedininae n. subfam.), Brachystomatidae rev. stat. (comprising the subfamilies Brachystomatinae, Ceratomerinae and Trichopezinae), and Dolichopodidae s.lat. The family Microphoridae is not recognized, and the Microphorinae and Parathalassiinae are assigned to the Dolichopodidae s.lat. The Dolichopodidae s.str. includes 15 subfamilies that were previously recognized within the family. Within the Empidoidea we found support for Atelestidae as the sister group to the Hybotidae and for the monophyly of Parathalassiinae + Dolichopodidae s.str. The Empididae remains poorly defined and the genera Homalocnemis Philippi, Iteaphila Zetterstedt, Anthepiscopus Becker, and Oreogeton Schiner are classified as incertae sedis within the                   Empidoidea. In addition, the following higher taxa are proposed: Symballophthalmini n. tribe, Bicellariini n. tribe, Oedaleinae rev. stat., and Trichininae rev. stat., which are all assigned to the Hybotidae. The genus Sematopoda Collin is tentatively assigned to Trichopezinae, and Xanthodromia Saigusa is transferred from Hemerodromiinae to Brachystomatinae.        All morphological characters are extensively discussed and illustrated, including details of the antennae, mouthparts, internal thoracic structures, wings, and male and female terminalia. In addition, a key to families and unplaced genus groups of the Empidoidea is provided. Feeding habits are also discussed in terms of the empidoid ground plan condition.

Historically, morphological characters have been used to support the monophyly, composition, and phylogenetic relationships of scorpion families. Although recent phylogenomic analyses have recovered most of these traditional higher-level relationships as non-monophyletic, certain key taxa have yet to be sampled using a phylogenomic approach. Salient among these is the monotypic genus Caraboctonus Pocock,1893, the type species of the family Caraboctonidae Kraepelin, 1905. Here, we examined the putative monophyly and phylogenetic placement of this family, sampling the library of C. keyserlingi Pocock, 1893 using high throughput transcriptomic sequencing. Our phylogenomic analyses recovered Caraboctonidae as polyphyletic due to the distant placement of the genera Caraboctonus and Hadrurus Thorell, 1876. Caraboctonus was stably recovered as the sister-group of the monotypic family Superstitioniidae Stahnke, 1940, whereas Hadrurus formed an unstable relationship with Uroctonus Thorell, 1876and Belisarius Simon, 1879. Four-cluster likelihood mapping revealed that the instability inherent to the placement of Hadrurus, Uroctonus and Belisarius was attributable to significant gene tree conflict in the internodes corresponding to their divergences. To redress the polyphyly of Caraboctonidae, the following systematic actions have been taken: (1) the family Caraboctonidae has been delimited to consist of 23 species in the genera Caraboctonus and Hadruroides Pocock, 1893; (2) Caraboctonidae, previously included in the superfamily Iuroidea Thorell, 1876 or as incertae sedis, is transferred to the superfamily Caraboctonoidea (new rank); (3) the superfamily Hadruroidea (new rank) is established and the status of Hadrurinae Stahnke, 1973 is elevated to family (Hadruridae new status) including 9 species in the genera Hadrurus and Hoffmannihadrurus Fet & Soleglad, 2004 and (4) we treat Uroctonus and Belisarius as insertae sedis with respect to superfamilial placement. Our systematic actions engender the monophyly of both Iuroidea and Caraboctonidae. Future phylogenomic investigations should target similar taxon-poor and understudied lineages of potential phylogenetic significance, which are anticipated to reveal additional non-monophyletic groups.

AbstractThe family Nemasomatidae is redefined to include onty genera with all sterna secondarily free from pleurotergites. Comments are given on the included genera, viz., Antrokoreana, Basoncopus gen. n. (type-species B. filiformis sp. n.) (Kazakhstan), Dasynemasoma, Thalassisobates, Sinostemmiulus, Nemasoma, and Orinisobates. Isobates coiffaiti Demange, 1961 is synonymized with Thalassisobates littoralis (Silvestri, 1903). Orinisobates is revised and shown to include O. soror sp. n. (Kuril Islands), O. microthylax sp. n. (Kamchatka and Siberia), O. gracilis (Verhoeff, 1933) (NW China), O. sibiricus (Gulicka, 1963) (Altai region, Kazakhstan), O. kasakstanus (Lohmander, 1933) (Kazahkstan), O. nigrior (Chamberlin, 1943) (eastern United States), O. utus (Chamberlin, 1912) (northwestern United States), and O. expressus (Chamberlin, 1941) (northwestern United States and adjacent Canada). Mimolene oregona Chambertin, 1941 and M. sectile Loomis & Schmitt, 1971 are synonymized with O. expressus. A possible case of parthenogenesis in O. microthylax is recorded. Evidence is presented for the following sister-group relationships: Antrokoreana + (Basoncopus + (Dasynemasoma + (Thalassisobates + (Sinostemmiulus + (Orinisobates + Nemasoma))))). The position of Basoncopus is uncertain, and O. soror may belong in a separate genus and constitute the sister-group of Orinisohates + Nemasoma. If soror does belong in Orinisobates, it is the sister-group of all its congeners. The American species of Orinisobates are shown probably to constitute a monophyietic group. The family is suggested to have originated in the eastern Palearctic region, Orinisobates having invaded North America via the Bering Bridge. Doubtful species and species erroneously assoiciated with the Nemasomatidae are listed. The genera Okeanobates and Yosidaiulus are excluded from the family and referred to Okeanobatidae stat. n. in superfamily Blaniuloidea. The genera Trichonemasoma, Telsonemasoma, and Chelojulus are also excluded from the Nemasomatidae and relegated to Julida incertae sedis.

Rove beetles of the genus Piestus Gravenhorst, 1806 are commonly captured under the bark of or inside decaying logs from Neotropical forests. Piestus belongs to the subfamily Piestinae, historically an ill-defined dumping-ground for Staphylinidae defined by plesiomorphic characters, but which has gradually been restricted in concept and currently includes only six additional extant genera worldwide. Piestinae in this restricted sense has been considered a probably monophyletic subfamily, but its status and phylogenetic position, as a possible sister-group of Osoriinae within the recently proposed Oxyteline group of staphylinid subfamilies, are uncertain and need confirmation. The main aim of the present study was to provide a morphological cladistic analysis and complete taxonomic revision of Piestus, which, as the type and most speciose genus of Piestinae, is critical for future phylogenetic studies involving the subfamily. In our study, the monophyly of Piestus is established and phylogenetic relationships among its species are proposed based on 70 adult morphological characters. Piestus is supported by 11 synapomorphies and high branch support. All species of Piestus are revised and the genus is redefined. The genus contains 43 species, including 13 species described here for the first time. The previously proposed subgenera Antropiestus Bernhauer, 1917, Eccoptopiestus Scheerpeltz, 1952, Elytropiestus Scheerpeltz, 1952, Lissopiestus Scheerpeltz, 1952, Piestus s. str., Trachypiestus Scheerpeltz, 1952 and Zirophorus Dalman, 1821 have not been confirmed, as they were found to be poly- or paraphyletic, or are here removed from Piestus, and therefore subgenera are not used. The main taxonomic changes are as follows. Lissopiestus, syn. nov. is proposed as new synonym of Eleusis Laporte, 1835 and its species, E. interrupta (Erichson, 1840), comb. rest., is transferred again to that genus. Antropiestus, syn. nov. and Eccoptopiestus, syn. nov. are proposed as new synonyms of Hypotelus Erichson, 1839 and their species, H. laevis (Solsky, 1872), comb. nov. and H. andinus (Bernhauer, 1917), comb. nov., are transferred to Hypotelus. Fourteen new synonymies are proposed (valid species listed first): P. lacordairei Laporte, 1835 = Z. furcatus Sharp, 1887, syn. nov.; P. capricornis Laporte, 1835 = P. frontalis Sharp, 1876, syn. nov.; P. pennicornis Fauvel, 1864 = P. plagiatus Fauvel, 1864, syn. nov.; P. rectus Sharp, 1876, syn. nov.; P. pygialis Fauvel, 1902, syn. nov.; P. surinamensis Bernhauer, 1928, syn. nov.; P. minutus Erichson, 1840 = P. nigrator Fauvel, 1902, syn. nov.; P. sulcatus Gravenhorst, 1806 = P. sanctaecatharinae Bernhauer, 1906, syn. nov.; P. condei Wendeler, 1955, syn. nov.; P. gounellei Fauvel, 1902 = P. wasmanni Fauvel, 1902, syn. nov.; P. mexicanus Laporte, 1835 = P. alternans Sharp, 1887, syn. nov.; P. aper Sharp, 1876 = P. schadei Scheerpeltz, 1952, syn. nov.; P. angularis Fauvel, 1864 = P. crassicornis Sharp, 1887, syn. nov.; H. andinus (Bernhauer, 1917) = P. strigipennis Bernhauer, 1921, syn. nov. One species is revalidated: P. fronticornis (Dalman, 1821), stat. rev., and one synonym is restored: P. penicillatus (Dalman, 1821) = P. erythropus Erichson, 1840, syn. rest. Neotypes are designated for P. lacordairei Laporte, 1835 and Oxytelus bicornis Olivier, 1811, and lectotypes are designated for P. puncticollis Fauvel, 1902, P. capricornis variety muticus Fauvel, 1902, P. zischkai Scheerpeltz, 1951, P. pennicornis Fauvel, 1864, P. plagiatus Fauvel, 1864, P. pygmaeus Laporte, 1835, P. niger Fauvel 1864, P. minutus Erichson, 1840, P. nigratror Fauvel, 1902, P. sulcatus Gravenhorst, 1806, P. sanctaecatharinae Bernhauer, 1906, P. sulcipennis Scheerpeltz, 1952, P. aper Sharp, 1876, P. schadei Scheerpeltz, 1952 and P. andinus Bernhauer, 1917.

The family Harrimaniidae (Hemichordata: Enteropneusta) is revised on the basis of morphological characters. The number of harrimaniid genera is increased to nine by the addition of Horstia n. gen., Mesoglossus n. gen., Ritteria n. gen. and Saxipendium, a genus previously assigned to the monospecific family Saxipendiidae. The number of species is increased to 34, resulting from the description of five new species from the eastern Pacific — Horstia kincaidi, Mesoglossus intermedius, M. macginitiei, Protoglossus mackiei and Ritteria ambigua. A description is supplied for a sixth harrimaniid species, Stereobalanus willeyi Ritter & Davis, 1904, which previously had the status of a nomen nudum. Four harrimaniids previously assigned to the genus Saccoglossus are transfered to the genus Mesoglossus — M. bournei, M. caraibicus, M. gurneyi and M. pygmaeus, while Saccoglossus borealis is reassigned to the genus Harrimania. Notes on habitat and zoogeography are included for the seven foregoing species and a table of diagnostic characters for existing and new species and a dichotomous key to the enteropneust families and harrimaniid genera are provided. Finally, a phylogenetic hypothesis concerning the Harrimaniidae is postulated, with discussion on the evolution of the group.

A taxonomic revision of the West Palaearctic species of the genus Pales Robineau-Desvoidy is presented and the identity of the genus is defined and discussed. Pales abdita sp. nov. from some localities in the Mediterranean region and Pales marae sp. nov. from Sardinia are described, illustrated and compared with similar species. A key to the ten known West Palaearctic species of Pales is presented. The rare genus Schembria Rondani is suggested as the possible sister-group of Pales and the male genitalia of the only known species, S. meridionalis Rondani, are figured for the first time.

Although the taxonomy of the ca 18 000 species of butterflies and skippers is well known, the family-level relationships are still debated. Here, we present, to our knowledge, the most comprehensive phylogenetic analysis of the superfamilies Papilionoidea, Hesperioidea and Hedyloidea to date based on morphological and molecular data. We reconstructed their phylogenetic relationships using parsimony and Bayesian approaches. We estimated times and rates of diversification along lineages in order to reconstruct their evolutionary history. Our results suggest that the butterflies, as traditionally understood, are paraphyletic, with Papilionidae being the sister-group to Hesperioidea, Hedyloidea and all other butterflies. Hence, the families in the current three superfamilies should be placed in a single superfamily Papilionoidea. In addition, we find that Hedylidae is sister to Hesperiidae, and this novel relationship is supported by two morphological characters. The families diverged in the Early Cretaceous but diversified after the Cretaceous–Palaeogene event. The diversification of butterflies is characterized by a slow speciation rate in the lineage leading to Baronia brevicornis , a period of stasis by the skippers after divergence and a burst of diversification in the lineages leading to Nymphalidae, Riodinidae and Lycaenidae.

AbstractExternal morphology of late-instar larvae and pupae of the coleopteran family Dascillidae is revised. Larvae studied for Dascillus Latreille with two species from Europe and North America, Notodascillus Carter from Australia and Pleolobus Philippi from Chile; pupae studied for D. davidsoni LeConte. Larval diagnosis and description of the family are updated. Dascillid larvae exhibit little morphological variation and share eight apparently apomorphic characters. Widely accepted sister-group relationship between Dascillidae and Rhipiceridae is not supported with larval morphology because ectoparasitic larvae of Rhipiceridae are poorly known and apparently highly modified morphologically. The superfamily Scarabaeoidea is unlikely to be a close relative of Dascillidae since this hypothesis is based mainly on habitat-dependent convergences of soil-dwellers (grub-like body shape, reduced stemmata) or possible symplesiomorphic similarities. Ten similarities between larvae of Dascillidae and Eulichadidae (Dryopoidea) were found. Some of these are possibly synapomorphies of these two groups. Larval and pupal morphology of Dascillidae is illustrated by 26 drawings.

The family Characidae is the most diverse among Neotropical fishes. Systematics of this family are mainly based on pre-cladistic papers, and only recently a phylogenetic hypothesis for Characidae was proposed by the author. That phylogeny was based on 360 morphological characters studied for 160 species, including representatives of families related to Characidae. This paper is based on that phylogenetic analysis, with the analyzed characters described herein and documented, accompanied by comparisons of their definition and coding in previous papers. Synapomorphies of each node of the proposed phylogeny are listed, comparisons with previous classifications provided, and autapomorphies of the analyzed species listed. Taxonomic implications of the proposed classification and the position of the incertae sedis genera within Characidae are discussed. A discussion of the phylogenetic information of the characters used in the classical systematics of the Characidae is provided.

This study examines the phylogeny, taxonomy, distribution and biology of the gasteruptiid subfamily Hyptiogastrinae and, at the same time, presents an overview of the family. Following a cladistic analysis of 35 discrete morphological characters, two monophyletic genera are recognised, Hyptiogaster Kieffer and Pseudofoenus s. l. Kieffer. As a consequence, the genera Aulacofoenus Kieffer, Crassifoenus Crosskey, and Eufoenus Szépligeti are synonymised with Pseudofoenus. A total of 88 species are recognised for the subfamily, 10 species of Hyptiogaster, which are restricted to mainland Australia, and 78 species of Pseudofoenus, 40 of which are described as new. Pseudofoenus has a restricted Gondwanan distribution and is found in Australia including Tasmania (65 spp.), New Guinea and New Britain (5 spp.), the south-west Pacific (New Caledonia, New Hebrides and Fiji – 2 spp.), New Zealand (4 spp.) and South America (2 spp.). No new species have been recorded from either New Zealand or South America. For Pseudofoenus, information on the distribution of each species, their biology (if known) and an identification key are presented.Following a taxonomic revision, the following new species are described: P. baileyi, sp. nov., P. baitetaensis, sp. nov., P. beverlyae, sp. nov., P. caperatus, sp. nov., P. cardaleae, sp. nov., P. carrabinensis, sp. nov., P. claireae, sp. nov., P. collessi, sp. nov., P. coorowensis, sp. nov., P. crosskeyi, sp. nov., P. douglasorum, sp. nov., P. eliseae, sp. nov., P. ericae, sp. nov., P. eustonensis, sp. nov., P. feckneri, sp. nov., P. gressitti, sp. nov., P. gullanae, sp. nov., P. hackeri, sp. nov., P. imbricatus, sp. nov., P. iqbali, sp. nov., P. kadowi, sp. nov., P. karimuiensis, sp. nov., P. kelleri, sp. nov., P. leinsterensis, sp. nov., P. macdonaldi, sp. nov., P. malkini, sp. nov., P. marshalli, sp. nov., P. masneri, sp. nov., P. mitchellae, sp. nov., P. morganensis, sp. nov., P. nalbarraensis, sp. nov., P. pumilis, sp. nov., P. schmidti, sp. nov., P. stevensi, sp. nov., P. tasmaniensis, sp. nov., P. taylori, sp. nov., P. umboiensis, sp. nov., P. walkeri, sp. nov. and P. zborowskii, sp. nov. The synonymy of Aulacofoenus, Crassifoenus and Eufoenus with Pseudofoenus result in the following new combinations: from Aulacofoenus: P. bungeyi (Jennings & Austin), comb. nov., P. deletangi (Schletterer), comb. nov., P. fallax (Schletterer), comb. nov., P. fletcheri (Jennings & Austin), comb. nov., P. goonooensis (Jennings & Austin), comb. nov., P. infumatus (Schletterer), comb. nov., P. kurmondi (Jennings & Austin), comb. nov., P. loxleyi (Jennings & Austin), comb. nov., P. marionae (Jennings & Austin), comb. nov., P. perenjorii (Jennings & Austin), comb. nov., P. swani (Jennings & Austin), comb. nov., P. thoracicus (Guérin Menéville), comb. nov., P. whiani (Jennings & Austin), comb. nov. and P. wubinensis (Jennings & Austin), comb. nov.; from Crassifoenus: P. houstoni (Jennings & Austin), comb. nov., P. grossitarsis (Kieffer), comb. nov and P. macronyx (Schletterer), comb. nov.; and from Eufoenus: P. antennalis (Schletterer), comb. nov., P. australis (Westwood), comb. nov., P. crassitarsis (Kieffer), comb. nov., P. darwini (Westwood), comb. nov., P. extraneus (Turner), comb. nov., P. ferrugineus (Crosskey), comb. nov., P. floricolus (Turner), comb. nov., P. inaequalis (Turner), comb. nov., P. melanopleurus (Crosskey), comb. nov., P. minimus (Turner), comb. nov., P. nitidiusculus (Turner), comb. nov., P. patellatus (Westwood), comb. nov., P. pilosus (Kieffer), comb. nov., P. reticulatus (Crosskey), comb. nov., P. rieki (Crosskey), comb. nov., P. ritae (Cheesman), comb. nov. and P. spinitarsis (Westwood), comb. nov. Pseudofoenus microcephalus (Crosskey), comb. nov. is transferred from Hyptiogaster and Eufoenus flavinervis (Kieffer) remains incertae sedis.
