A rich fauna of 19 edaphic species inhabiting the leaf litter of tropical forests is reported for the first time from the Australian Wet Tropics.     

Revision of the subgenus Orthoscymnus Canepari of Scymnus Kugelann (Coleoptera,Coccinellidae), with descriptions of four new species

The subgenus Orthoscymnus Canepari, 1997 of Scymnus Kugelann, 1794 is herein revised. Seven species of the Orthoscymnus fauna are recognized, of which four species, Scymnus (Orthoscymnus) jilongicus sp. n., Scymnus (Orthoscymnus) paradoxus sp. n., Scymnus (Orthoscymnus) crispatus sp. n. and Scymnus (Orthoscymnus) duomaculatus sp. n., are described as new to science. Scymnus (Orthoscymnus) rhododendri Canepari is recorded from China for the first time. Scymnus (Pullus) robustibasalis Yu is transferred to the subgenus Orthoscymnus (comb. n.). All species are diagnosed, described and illustrated, and distributions are provided for each species. A key to the species is included.     

A review of myrmecophilous mites of the family Microdispidae (Acari,Heterostigmatina) of Western Siberia

Five species of myrmecophilous microdispid mites (Acari: Microdispidae) are recorded from Western Siberia, Russia. Unguidispus lasii Kurosa, 1979, Unguidispus japonicus Kurosa, 1979, Caesarodispus minutus (Sevastianov, 1981), and Caesarodispus samsinaki (Mahunka, 1967), comb. n. are reported from Russia for the first time. Unguidispus polyctenus (Sevastianov, 1969) and Caesarodispus samsinaki are redescribed. The keys to species of the genera Unguidispus Mahunka, 1970 and Caesarodispus Mahunka, 1977 are provided.     

Checklist of the superfamilies Oestroidea and Hippoboscoidea of Finland (Insecta,Diptera)

An updated checklist of the superfamilies Oestroidea and Hippoboscoidea recorded from Finland is presented. The checklist covers the following families: Calliphoridae, Rhiniidae, Sarcophagidae, Rhinophoridae, Tachinidae, Oestridae and Hippoboscidae.     

Checklist of the Cecidomyiidae (Diptera) of Finland

A list of the 356 species of Cecidomyiidae (Diptera) recorded from Finland is presented, which comprises 6 Lestremiinae, 156 Micromyinae, 16 Winnertziinae, 69 Porricondylinae, and 109 Cecidomyiinae. The faunistic knowledge of Finnish Winnertziinae, Porricondylinae and Cecidomyiinae is regarded as particularly poor. Based on species numbers known from other countries in Europe, a conservative estimate is 700–800 species of Cecidomyiidae actually occurring in Finland.     

Description of six new species of Lycocerus Gorham (Coleoptera,Cantharidae), with taxonomic note and new distribution data of some other species

Six new species of Lycocerus Gorham are described, Lycocerus gracilicornis sp. n. (China: Sichuan), Lycocerus longihirtus sp. n. (China: Yunnan), Lycocerus sichuanus sp. n. (China: Sichuan), Lycocerus hubeiensis sp. n. (China: Hubei), Lycocerus napolovi sp. n. (Vietnam: Sa Pa) and Lycocerus quadrilineatus sp. n. (Vietnam: Sa Pa), and provided with illustrations of habitus, antennae and aedeagi of male or and antennae, abdominal sternites VIII and genitalia of female. Lycocerus rubroniger Švihla, 2011 is synonymized with Lycocerus obscurus Pic, 1916. Lycocerus hickeri Pic, 1934 and Lycocerus obscurus are provided with illustrations of abdominal sternites VIII of female.

Phylogenies of symbiotic genes of Bradyrhizobium symbionts of legumes of economic and environmental importance in Brazil support the definition of the new symbiovars pachyrhizi and sojae

Bradyrhizobium comprises most tropical symbiotic nitrogen-fixing strains, but the correlation between symbiotic and core genes with host specificity is still unclear. In this study, the phylogenies of the nodY/K and nifH genes of 45 Bradyrhizobium strains isolated from legumes of economic and environmental importance in Brazil (Arachis hypogaea, Acacia auriculiformis, Glycine max, Lespedeza striata, Lupinus albus, Stylosanthes sp. and Vigna unguiculata) were compared to 16S rRNA gene phylogeny and genetic diversity by rep-PCR. In the 16S rRNA tree, strains were distributed into two superclades—B. japonicum and B. elkanii—with several strains being very similar within each clade. The rep-PCR analysis also revealed high intra-species diversity. Clustering of strains in the nodY/K and nifH trees was identical: 39 strains isolated from soybean grouped with Bradyrhizobium type species symbionts of soybean, whereas five others occupied isolated positions. Only one strain isolated from Stylosanthes sp. showed similar nodY/K and nifH sequences to soybean strains, and it also nodulated soybean. Twenty-one representative strains of the 16S rRNA phylogram were selected and taxonomically classified using a concatenated glnII-recA phylogeny; nodC sequences were also compared and revealed the same clusters as observed in the nodY/K and nifH phylograms. The analyses of symbiotic genes indicated that a large group of strains from the B. elkanii superclade comprised the novel symbiovar sojae, whereas for another group, including B. pachyrhizi, the symbiovar pachyrhizi could be proposed. Other potential new symbiovars were also detected. The co-evolution hypotheses is discussed and it is suggested that nodY/K analysis would be useful for investigating the symbiotic diversity of the genus Bradyrhizobium.     

Crustaceans from antipatharians on banks of the northwestern Gulf of Mexico

The stalked barnacle Oxynaspis gracilis, the chirostylid squat lobster Uroptychus sp., and the caridean shrimps Periclimenes cf. antipathophilus and Pseudopontonides principis have been collected at 68–124 m by a remotely operated vehicle (ROV) on banks in the northern Gulf of Mexico. These species inhabited six species of antipatharian hosts. Pseudopontonides principis, Oxynaspis gracilis, and Uroptychus sp. were not confined to a single host species. Except for Oxynaspis gracilis, collected by ROV in 2004–2005, these species have not been reported previously in the northwestern Gulf of Mexico.     

Spatial distribution of brood-bearing females of limnetic species of Cladocera

In this study, the spatial distribution of brood-bearing females of five species of limnetic cladocerans (Daphnia cucullata, D. longispina, Bosmina coregoni, B. longirostris, Diaphanosoma brachyurum) in the deep mesotrophic lake in relation to the predation pressure of planktivorous fish (roach Rutilus rutilus, perch Perca fluviatilis, catfish Ictalurus nebulosus, white fish Coregonus albula, bleak Alburnus alburnus), and planktonic invertebrates (cyclopoids Mesocyclops leuckartii, Thermocyclops oithonoides, T. crassus, and cladoceran Leptodora kindtii) as well as some environmental variables was estimated. Most cladocerans showed apparent differences in horizontal distribution (ANOVA F = 0.2–0.45, P < 0.05) in the littoral zone and lack of such differences in the pelagic zone (F = 0.07–0.13, P > 0.05). Vertical distribution of most species, in turn, showed a clear pattern in the pelagic zone (F = 0.31–0.39, P < 0.05) and less regularities in the littoral zone (F = 0.15–029, P > 0.05). The differences in spatial distribution of non-predated and predated species suggest that predation pressure, but not predatory type, was an important factor structuring their distribution. Other factors that affected their distribution were conductivity, dissolved oxygen, TOC and macrophyte biomass; however, most of those variables better explained the distribution of brood-bearing cladocerans in the vertical than horizontal aspect.     

An annotated catalogue of the types of Chrysididae (Hymenoptera) at the Swedish Museum of Natural History,Stockholm, with brief historical notes

A critical and annotated catalogue of 72 types of Chrysididae (Hymenoptera) belonging to 53 species and subspecies housed in the Swedish Museum of Natural History is given. The lectotypes of Chrysis diversa Dahlbom, 1845, Chrysis soror Dahlbom, 1854, Chrysura sulcata Dahlbom, 1845 and Holopyga amoenula Dahlbom, 1845 are designated. The previous lectotype of Chrysis diversa Dahlbom, 1845 is set aside. Five new synonymies are proposed: Chrysis elegans var. smaragdula Trautmann, 1926 (currently Chrysis elegans ssp. interrogata Linsenmaier, 1959 repl. name for smaragdula Trautmann, nec Fabricius, 1775), syn. n. of Chrysis confluens (Dahlbom, 1845); Chrysis eximia Mocsáry, 1889, syn. n. of Chrysis poecila Mocsáry, 1889; Chrysis pyrrhina Dahlbom, 1845, syn. n. of Chrysis erythromelas Dahlbom, 1845; Chrysis separata Trautmann, 1926, syn. n. of Chrysis lateralis Dahlbom, 1845; Chrysis sicula Abeille de Perrin, 1877, syn. n. of Chrysis erythromelas Dahlbom, 1845. Chrysis serena Radoszkowski, 1891 is the first available name for Chrysis pyrrhina sensu auctorum. Chrysis erythromelas Dahlbom, 1845 is revaluated as valid species. The neotype of Chrysis inaequalis Dahlbom, 1845 is designated in the Linsenmaier collection (NMLS). Illustrations of 34 types are given.     

Melithaeidae of Japan (Octocorallia,Alcyonacea) re-examined with descriptions of 11 new species

Japanese melithaeid type material is re-examined and re-described. The sclerites of the different species are depicted using Scanning Electron Microscopy. All Japanese species of the family Melithaeidae treated here belong to the genus Melithaea and are endemic to Japanese waters. Old museum material and newly collected specimens from Japanese waters are identified after comparison with this type material. Acabaria modesta var. abyssicola is regarded a separate species, here named Melithaea abyssicola (Kükenthal, 1909). In addition, 11 new species are described: Melithaea boninensis sp. n., Melithaea doederleini sp. n., Melithaea isonoi sp. n., Melithaea keramaensis sp. n., Melithaea oyeni sp. n., Melithaea ryukyukensis sp. n., Melithaea sagamiensis sp. n., Melithaea satsumaensis sp. n., Melithaea suensoni sp. n., Melithaea tanseii sp. n., and Melithaea tokaraensis sp. n.. Pleurocorallium confusum Moroff, 1902, Pleurocoralloides formosum Moroff, 1902, Melitodes flabellifera Kükenthal, 1908, and Melitodes densa Kükenthal, 1908 are synonymized with Melithaea japonica (Verrill, 1865). We have designated a neotype for Melithaea mutsu Minobe, 1929. A key to the Japanese melithaeids is presented.     

A revision of the Nearctic species of Liancalus Loew (Diptera,Dolichopodidae)

The genus Liancalus Loew is revised for the Nearctic Region. Seven species are documented from this region including two new species: Liancalus genualis Loew, Liancalus hydrophilus Aldrich, Liancalus limbatus Van Duzee, Liancalus pterodactyl sp. n., Liancalus querulus Osten Sacken, Liancalus similis Aldrich, and Liancalus sonorus sp. n. Lectotypes are designated for the following species: Liancalus genualis, Liancalus hydrophilus, Liancalus querulus, and Liancalus similis. The species are illustrated, a key to males and females is provided, and their distributions mapped. Adults of Liancalus are some of the largest species of Dolichopodidae and commonly occur on waterfalls and vertical seeps.     

Revision of Paranastatus Masi (Eupelmidae,Eupelminae) with descriptions of four new species

Paranastatus Masi, 1917 (Eupelmidae, Eupelminae) was originally described based on two species from Seychelles: Paranastatus egregius and Paranastatus violaceus. Eady (1956) subsequently described Paranastatus nigriscutellatus and Paranastatus verticalis from Fiji. Here, four new species of Paranastatus are described: Paranastatus bellus Scallion, sp. n. and Paranastatus pilosus Scallion, sp. n. from Indonesia, and Paranastatus halko Scallion, sp. n. and Paranastatus parkeri Scallion, sp. n. from Fiji. A key to all Paranastatus species based on females is included and lectotypes are designated for Paranastatus egregius and Paranastatus violaceus. Finally, previously unobserved colour variation from newly collected material of Paranastatus verticalis, distribution patterns of species, and possibilities for future research are discussed.     

Annotated check list of the Pyraloidea (Lepidoptera) of America North of Mexico

An annotated check list of Pyraloidea of North America north of Mexico is presented, including 861 Crambidae and 681 Pyralidae with 1542 total species. It includes all new species described, tropical species with new records in the United States, and species introduced from Europe and Asia since 1983. The Notes section provides the seminal citations, data and/or commentary to all changes since 1983 for easy and future reference. In addition, this list proposes seven new generic combinations, the transfer of a phycitine species, Salebria nigricans (Hulst), to Epipaschiinae and its syn. n. with Pococera fuscolotella (Ragonot), and three new records for the United States. Purposefully, no new taxa are described here, but we found a gradual increase of 10% in the number of species described since 1983. Finally, we also include a list of thirteen species not included or removed from the MONA list. Many higher-level changes have occurred since 1983 and the classification is updated to reflect research over the last 30 years, including exclusion of Thyrididae and Hyblaeidae from the superfamily and recognition of Crambidae and Pyralidae as separate families. The list includes multiple changes to subfamilies based on morphology such as the synonymization of the Dichogamini with the Glaphyriinae, but also incorporating recent molecular phylogenetic results such as the synonymization of the Evergestinae with the Glaphyriinae.     

Taxonomic review of the Ornithocheirus complex (Pterosauria) from the Cretaceous of England

Over a decade after the last major review of the Cambridge Greensand pterosaurs, their systematics remains one of the most disputed points in pterosaur taxonomy. Ornithocheiridae is still a wastebasket for fragmentary taxa, and some nomenclatural issues are still a problem. Here, the species from the Cretaceous of England that, at some point, were referred in Ornithocheirus, are reviewed. Investigation of the primary literature confirmed that Criorhynchus should be considered an objective junior synonym of Ornithocheirus. Taxonomic review of more than 30 species known from fragmentary remains showed that 16 of them are undiagnosable (nomina dubia): Palaeornis cliftii, Cimoliornis diomedeus, Pterodactylus compressirostris, Pterodactylus fittoni, Pterodactylus woodwardi, Ornithocheirus brachyrhinus, Ornithocheirus carteri, Ornithocheirus crassidens, Ornithocheirus dentatus, Ornithocheirus enchorhynchus, Ornithocheirus eurygnathus, Ornithocheirus oxyrhinus, Ornithocheirus scaphorhynchus, Ornithocheirus tenuirostris, Ornithocheirus xyphorhynchus, and Pterodactylus sagittirostris. Fourteen species are considered valid, and diagnoses are provided to all of them: Ornithocheirus simus, Lonchodraco giganteus comb. n., Lonchodraco machaerorhynchus comb. n., Lonchodraco(?) microdon comb. n., Coloborhynchus clavirostris, ‘Ornithocheirus’ capito, Camposipterus nasutus comb. n., Camposipterus(?) sedgwickii comb. n., Camposipterus(?) colorhinus comb. n., Cimoliopterus cuvieri comb. n., ‘Ornithocheirus’ polyodon, ‘Ornithocheirus’ platystomus, ‘Pterodactylus’ daviesii, and ‘Ornithocheirus’ denticulatus. These species are referred in the genera Ornithocheirus, Lonchodraco gen. n., Coloborhynchus, Cimoliopterus gen. n., and Camposipterus gen. n., but additional genera are probably present, as indicated by the use of single quotation marks throughout the text. A cladistic analysis demonstrates that Anhangueridae lies within a newly recognized clade, here named Anhangueria, which also includes the genera Cearadactylus, Brasileodactylus, Ludodactylus, and Camposipterus. The anhanguerian ‘Cearadactylus’ ligabuei belongs to a different genus than Cearadactylus atrox. Lonchodraconidae fam. n. (more or less equivalent to Lonchodectidae sensu Unwin 2001) is a monophyletic entity, but its exact phylogenetic position remains uncertain, as is the case of Ornithocheirus simus. Therefore, it is proposed that Ornithocheiridae should be constricted to its type species and thus is redundant. Other taxa previously referred as “ornithocheirids” are discussed in light of the revised taxonomy.     

A new species and synonymy of the Neotropical Eucelatoria Townsend and redescription of Myiodoriops Townsend

The New World tropics represents the most diverse region for tachinid parasitoids (Diptera: Tachinidae), but it also contains the most narrowly defined, and possibly the most confusing, tachinid genera of any biogeographic region. This over-splitting of genera and taxonomic confusion has limited progress toward our understanding the family in this region and much work is needed to revise, redefine, and make sense of the profusion of finely split taxa. In a recent analysis of the Neotropical genus Erythromelana Townsend, two species previously assigned to this genus, Euptilodegeeria obumbrata (Wulp) and Myiodoriops marginalis Townsend were reinstated as monotypic genera. In the present study, we demonstrate that Euptilodegeeria obumbrata (Wulp), previously assigned to three different genera, represents in fact a species of the large New World genus Eucelatoria Townsend, in which females possess a sharp piercer for oviposition. We also show that the species Eucelatoria carinata (Townsend) belongs to the same species group as Eucelatoria obumbrata, which we here define and characterize as the Eucelatoria obumbrata species group. Additionally, we describe Eucelatoria flava sp. n. as a new species within the Eucelatoria obumbrata species group. Finally, we redescribe the genus Myiodoriops Townsend and the single species Myiodoriops marginalis Townsend.     

Contents of the poison apparatus of some species of Pheidole ants

Four Old World species of Pheidole ants contain different mixtures of farnesene-type hydrocarbons in their poison apparatus, and the mixture is different between the minor and major workers within a species. A bishomofarnesene (C₁₇H₂₈) provides approximately half of the secretion of the Dufour glands of minor workers of Pheidole pallidula. (Z,E)-α-Farnesene constituted 96% of the Dufour secretion of major workers of P. pallidula, but only 20% of that of minors. The Dufour glands of minor workers of Pheidole sinaitica contain a mixture of farnesene homologues with (Z,E)-α-farnesene and the bishomofarnesene also found in P. pallidula predominant. The mixture in major workers was similar but had, in addition, a small amount of (E)-β-farnesene. The Dufour glands of Pheidole teneriffana minors contain chiefly the same bishomofarnesene found in P. pallidula and P. sinaitica while major workers contain (Z,E)-α-farnesene. Pheidole megacephala minor workers contained small amounts of eight farnesenes, while major workers contained essentially no farnesenes. The poison glands of minor workers of P. pallidula contain 3-ethyl-2,5-dimethylpyrazine. No pyrazine compounds were found in the major workers of P. pallidula or the minor workers of P. sinaitica. The poison glands of the major workers of P. sinaitica contained larger amounts of tetra-substituted pyrazines. No pyrazines were found in the poison reservoirs of major or minor workers of P. teneriffana or P. megacephala.
