Larval morphology of Macrovatellus haagi (Wehncke) and phylogeny of Hydroporinae (Coleoptera: Dytiscidae)
Authors: Torres Patricia , Michat Mariano 
Published: March 2011

AbstractThe three larval instars of Macrovatellus haagi (Wehncke) are described and figured for the first time. Detailed morphometric, chaetotaxic and porotaxic analyses are provided. They are compared with the immatures of other species of the genus and the tribe Vatellini. Tribal- and generic-level larval characters are identified based on the descriptions herein provided and those found in the literature. A Vatellini larva is distinguished by its very characteristic nasale, antennomere 1 and maxillary stipes elongate, prementum as long as broad, and very long siphon and urogomphi. Macrovatellus Sharp differs from Derovatellus Sharp by the presence of lateral spinulae on prementum, and secondary setation on antennomeres 1 and 2 and maxillary palpomere 1. Third instar of M. haagi differs from M. mexicanus Sharp by its one-segmented labial palpi and siphon shorter than cerci. A phylogenetic analysis based on 57 larval characters and including members of six tribes of the Hydroporinae was conducted. It supports the hypothesis of a derived condition of the tribe Vatellini within this subfamily. The clade Bidessini + Vatellini + Hyphydrini and the clade Vatellini + Hyphydrini are well supported. Several characters suggest a monophyletic origin of the tribe Vatellini, and two synapomorphies support monophyly of the genus Macrovatellus.
The genus Sciarotricha gen. n. (Sciaridae) and the phylogeny of recent and fossil Sciaroidea (Diptera)
Authors: Vilkamaa Pekka , Hippa Heikki 
Published: March 2011

AbstractThe phylogeny of the main groups of the Sciaroidea, including the fossil Antefungivoridae, Archizelmiridae, Mesosciophilidae, Pleciofungivoridae, Pleciomimidae, Protopleciidae and Bolitophilidae: Mangasinae, and an extant new taxon, was studied by parsimony analysis. Two cladistic analyses of seventy-eight morphological characters from adults were made. One analysis, with forty-one extant taxa in the ingroup and the other, with the addition of twelve fossil taxa, both produced two most parsimonious cladograms. The phylogenetic hypotheses obtained differed from each other, and in part also to a great extent from previous ones although most of the traditionally recognized groups appeared monophyletic, including the speciose Cecidomyiidae and Sciaridae. The Cecidomyiidae (fossil analysis) or the Keroplatidae-Ditomyiidae (extant analysis) appeared as the sister-group of the rest of the Sciaroidea. Following on from these analyses, we propose emending the current Sciaridae to include the following subfamilies: Archizelmirinae stat. n., Rangomaraminae stat. n., Sciarinae, Sciarosominae subfam. n. and Sciarotrichinae subfam. n. A new taxon from Namibia, Sciarotricha biloba gen. n., sp. n. is described, and, according to the phylogenetic analysis, is placed in the Sciaridae (Sciarotrichinae). The sister-group of the Sciaridae as newly defined is the Mycetophilidae group, in the extant analysis including the Mycetophilidae, Manotidae, Lygistorrhinidae, Pterogymnus and Sciaropota, and in the fossil analysis even including the Mesosciophilidae and the Ohakunea group (Ohakunea + Colonomyia).
Chironomids (Diptera: Chironomidae) of Dominican amber. Ablabesmyia electrohispaniolana, sp. n. and paleoecological indications due to subfamily proportions
Authors: Grund Martin 
Published: March 2011

AbstractThe first fossil Chironomid species in Dominican amber, Ablabesmyia electrohispaniolana, sp. n. is described. Additionally, a first overview on the proportions of three subfamilies in this fossil chironomid fauna is given. This percent composition is compared with the chironomid fauna in the tropical lowlands of South America and with the fauna of Andean-Patagonian flowing waters. The data presented and knowledge on today's chironomid fauna is not detailed enough to draw new conclusions about the ancient amber forest, but it is shown how chironomids in Dominican amber can contribute in reconstructing palaeoenvironments even at subfamilial level.
On new species of the Neotropical spider genus Attacobius Mello-Leitão, 1923 (Araneae, Corinnidae, Corinninae), with a cladistic analysis of the tribe Attacobiini
Authors: Bonaldo Alexandre , Brescovit Antonio 
Published: March 2011

AbstractA cladistic analysis of the Attacobiini spiders (Corinnidae, Corinninae) is made from 11 species in the tribe, plus two Corinninae outgroup species (Septentrinna yucatan and Falconina gracilis), scored for 70 characters. Attacobiini, Attacobius and a group composed by A. attarum Roewer, A. luederwaldti (Mello-Leitão) and A. nigripes (Mello-Leitão) are the best supported clades in the analysis. Six new Brazilian species are described: Attacobius blakei, A. tucurui and A. uiriri, from the state of Pará; A. lamellatus and A. kitae, from Tocantins and A. carranca, from Tocantins and Bahia. The known distribution ranges of A. attarum and A. luederwaldti are extended from Rio de Janeiro to Brasilia (Distrito Federal) and from São Paulo to Minas Gerais and Mato Grosso, respectively. A 10 percent KOH preparation of the male palp of A. carranca suggests that the Attacobiini tegular process is homologous to the median apophysis, which is putatively symplesiomorphic in Corinninae.
Biodiversity of Apis mellifera iberica (Hymenoptera: Apidae) from northeastern Spain assessed by mitochondrial Analysis
Authors: Rúa Pilar De La , Galián José , Serrano José , Hernández-García Raquel , Jiménez Yolanda 
Published: March 2011

AbstractThe molecular variability has been analysed at the mitochondrial level in 288 honeybee colonies from 28 localities distributed along the four Catalonian provinces. In total sixteen different haplotypes belonging to three evolutionary lineages were found. The west European M lineage has been found at a high frequency in the four provinces and is fixed in Lérida, whereas the African A lineage shows a cline of distribution being more frequent in the northern Catalonia. The east European C lineage has been found in three colonies (one in Gerona and two from Barcelona). These results are most likely attributable to natural evolution events but the human influence should also be considered as an agent causing recent changes in the distribution of the honeybee populations. New insights about the evolution of the honeybee populations from the Iberian Peninsula are discussed in the light of the new information provided.

On the basis of the wing patterns, six species-groups are established: the atrofrons, grandipalpis, fleximediata, javana, latiparma and zonaria groups. A key to the all species of this genus is provided.
Review of fungus gnats of the genus Tarnania Tuomikoski, with a phylogeny of the Rymosia s.l. genus group (Diptera: Mycetophilidae)
Authors: Kjærandsen Jostein 
Published: March 2011

AbstractThe four known species of Tarnania Tuomikoski are reviewed, viz. T. dziedzickii (Edwards, 1941), T. fenestralis (Meigen, 1818), T. nemoralis (Edwards, 1941), and T. tarnanii (Dziedzicki, 1910). Males and females are re-described, photographed and their terminalia figured. An attempt is made to homologize and name specific substructures of the male gonostylus, widely recognizable within the tribe Exechiini. A phylogenetic analysis of the Tarnania species, including representatives of the six other genera of the Rymosia s. lat. genus group, strengthens the view that Tarnania is monophyletic. Tarnania is supported by six unambiguous character changes of which three are considered to be unique synapomorphies, viz. 1) lower parts of metepisternum and metepimeron covered with campaniform sensilla; 2) hind tibia with several curved bristles posterodorsally, placed irregularly in more than one row; and 3) anterior branch of male gonostylus forming an elongated, bifurcated lobe. The most parsimonious hypothesis for relationships among the species of Tarnania is ((T. tarnanii + T. nemoralis) + (T. dziedzickii + T. fenestralis)). The practice of regarding the genera of the Rymosia s. lat. genus group as an assemblage of plesiomorphic genera is also supported, the most parsimonious hypothesis for relationships among them being (Notolopha (Allodiopsis (Myrosia (Synplasta (Tarnania + (Rymosia + Pseudorymosia)))))). Tarnania is most diverse in northwestern Europe, with all four species known from Norway, Sweden, Great Britain, Belgium, Germany, Switzerland, and France. T. dziedzickii extends its distribution southwards to include the North African and the Near East Regions. T. fenestralis is widely distributed in the western Palaearctic Region and extends its distribution eastwards to the eastern Palaearctic region. Only T. tarnanii displays a wide Holarctic distribution including most of Russia, Alaska, Canada and Greenland.
Anatomical investigations of the male reproductive system of five species of Calaphidinae (Hemiptera, Aphidoidea)
Authors: Wieczorek Karina 
Published: March 2011

AbstractThe structure of the male reproductive system of 5 species of Calaphidinae Clethrobius comes, Euceraphis betulae, Myzocallis (Lineomyzocallis) walshii, Tuberculatus (Tuberculoides) annulatus and Tuberculatus (Tuberculoides) neglectus is discussed. C. comes and E. betulae feed on birches (Betula), whereas M. (L.) walshii, T. (T.) annulatus, and T. (T.) neglectus are associated with oaks (Quercus). On the basis of histological sections and whole mount preparations the following elements in the structure of the male reproductive system have been examined: the number of testis follicles and the stage of spermatogenesis, the connection of follicles and vasa deferentia, the position of the proximal part of vasa deferentia as well as the development of accessory glands and the ejaculatory duct. In males of studied species the characters of the reproductive system have been observed: each testis holds 3 or 4 follicles, strongly elongated and arranged in a rosette. Vasa deferentia run separately along their length, only in the proximal part their walls cling together. Accessory glands are strongly elongated, sometimes asymmetric (T.(T.) annulatus) whereas the ejaculatory duct is usually reduced (in exception C. comes). These characters were then used to supplement morphological data in order to interpret developmental trends in the Calaphidinae.
Species delimitation in the leaf beetle genus Macroplea (Coleoptera, Chrysomelidae) based on mitochondrial DNA, and phylogeographic considerations
Authors: Kölsch Gregor , Pedersen Bo Vest , Biström Olof 
Published: March 2011

AbstractThe genus Macroplea Samouelle, 1819 is a group of highly specialized aquatic leaf beetles occurring in the Palaearctic. Since the members of this genus are morphologically very similar, we addressed the question of species identification and delimitation by analysing the second half of the mitochondrial gene coding for the cytochrome oxidase I (COI) subunit. Species limits are inferred from the multimodal frequency distribution of genetic distances between specimens: low genetic distances within a species are clearly set apart from distances between species. The species status of the hitherto controversial species M. japana (Jacoby, 1885) is confirmed. The pattern of nucleotide and amino acid substitutions is discussed in the light of functional domains of the COI molecule. Although the data are preliminary, the results provide new data on the distribution of the species. Together with the phylogenetic analysis they allow for a discussion of the phylogeography of the genus.
Species identity of Macrolophus melanotoma (Costa 1853) and Macrolophus pygmaeus (Rambur 1839) (Insecta: Heteroptera: Miridae) based on morphological and molecular data and bionomic implications
Authors: Sanchez Juan Antonio , Cenis Jose Luis , Cassis Gerasimos , Martinez-Cascales Jose Isidro 
Published: March 2011

AbstractMacrolophus contains a small group of Palaearctic species with very simple and similar external morphology. The classification of these species has been based on variable characters such as body measurements, the height of the black band-shaped macula behind the eyes and the colour of the first antennal segment. Macrolophus melanotoma (Costa 1853), Macrolophus pygmaeus (Rambur 1839) and Macrolophus costalis Fieber 1858, are the most reputed predators of the genus. The classification history of M. melanotoma and M. pygmaeus shows a great number of misconceptions that have left the identity of the two species in confusion. Despite the economic importance of these two species, they have not received comprehensive taxonomical treatment until now. In this work, the morphological and sequence variation of a cytochrome b fragment (320 bp) were analysed to determine the identity of M. melanotoma and M. pygmaeus. Macrolophus costalis, Dicyphus cerastii Wagner 1951b, Dicyphus tamaninii Wagner 1951b, Cyrtopeltis geniculata Fieber 1861 and Nesidiocoris tenuis (Reuter 1895) were used as outgroup taxons in the phylogenetic analyses. Several evolutionary models were explored under a maximum likelihood framework. Macrolophus melanotoma and M. pygmaeus were classified as two distinct species based on monophyly, molecular and morphological data. Nodes at the species level were supported by high bootstrap values. M. pygmaeus and M. costalis are sister species, M. melanotoma basal to them. The shape of the black macula behind the eye may be used as a diagnostic character to differentiate M. melanotoma from M. pygmaeus with some degree of confidence.
A new genus and species of trichobiine bat flies (Diptera: Hippoboscoidea: Streblidae) from Costa Rica
Authors: Dick Carl , Wenzel Rupert 
Published: March 2011

AbstractA new genus and species of parasitic bat fly, Megistapophysis mordax gen. n., sp. n., is diagnosed and described within the subfamily Trichobiinae (Diptera: Hippoboscoidea: Streblidae). Illustrations of the wing, habitus, and male genitalia are provided. The new genus has affinities to species of Megistopoda Macquart, 1852, Neotrichobius Wenzel & Aitken, 1966, Paratrichobius Costa Lima, 1921, and the Trichobius phyllostomae group of species. Morphological affinities of related taxa to the new genus are discussed, and information regarding ecology and host associations is presented. The new genus is known exclusively from Costa Rican Sturnira mordax (Goodwin, 1938) (Chiroptera: Phyllostomidae: Stenodermatinae).
Phylogenetic review of desert firefly taxonomic characters (Coleoptera: Lampyridae: Microphotus)
Authors: Cognato Anthony , Usener Jessica 
Published: March 2011

AbstractSpecies are often difficult to discern when morphological attributes do not reflect taxonomic boundaries. Cladistic analysis using individuals as OTUs allows for morphological attributes to be determined as either taxonomic characters or traits. This approach is used to review 16 taxonomic attributes that define Microphotus species. In addition, mitochondrial cyctochrome oxidase I and luciferase DNA data are analyzed for phylogenetic signal and for the potential use for species diagnosis. Analysis of morphological attributes for 317 Microphotus individuals yielded 5000 trees with poor resolution. Individuals of each species where not monophyletic thus failing to reject the hypothesis that the 16 taxonomic attributes are traits, hence they are not taxonomic characters. Separate cladistic analyses of mitochondrial COI and luciferase gene data for ten and seven OTUs, respectively, each produced one parsimonious tree. Topologies of these trees were incongruent by the placement of M. chiricahuae, M. pecosensis, and M. fragilis. Cladistic analysis of all data for 11 OTUs produced two equally parsimonious trees which were unresolved for two nodes. All data sets supported the trees, however, the luciferase data showed the most conflict with the other data sets. The data support the synonymy of M. decarthrus Fall 1912 and M. fragilis Oliver 1912 based on lack of morphological variation and geographic and temporal proximity of collection localities. Additional data is needed to make a more robust statement of Microphotus phylogeny and taxonomy.
Phylogenetic analysis of Anomalophylla Reitter, 1887 (Coleoptera, Scarabaeidae: Sericini)
Authors: Ahrens Dirk 
Published: March 2011

AbstractThe phylogeny of the genus Anomalophylla Reitter, 1887 is investigated based on comparative morphology involving 68 characters. Three monophyletic lineages were recognized from the strict consensus tree within the ingroup: (1) Anomalophylla; (2) Gastroserica + Neoserica; (3) Microserica soppongensis + M. panzona. Monophyly of Anomalophylla was evident with highest branch supports in both analyses with unweighted and weighted characters, however its sister taxon was not apparent with present data set. Monophyly of Microserica species included in this analysis could not be shown according to the tree topology.
Revision of the genus Onychiuroides Bagnall, 1948 (Collembola: Onychiuridae: Onychiurinae)
Authors: Pomorski Romuald 
Published: March 2011

AbstractThe European genus Onychiuroides Bagnall, 1948 is revised. The genus is defined within the subfamily Onychiurinae on the basis of the arrangement of the dorsal posterior cephalic pseudocelli (set in a triangle), presence of 11 setae in the distal whorl of tibiotarsi and the structure of the reduced furca (finely granulated area with 1+1 setulae posteriorly, in contact with the border between abdominal sterna III and IV). Seven new species are described (O. igori sp. n., O. pirinensis sp. n., O. paoloi sp. n., O. cerberus sp. n., O. bojani sp. n., O. peteri sp. n. and O. occultus sp. n.). Nine previously known species are redescribed on the basis of types and new specimens [O. anelli (Denis, 1938), O. bureschi (Handschin, 1928) comb. nov., O. canzianus (Stach, 1934) comb. nov., O. hrabei (Rusek, 1963) comb. nov., O. papillaeferus (Stach, 1946) comb. nov., O. postumicus (Bonet, 1931) comb. nov., O. pseudogranulosus (Gisin, 1951), O. quadripapillatus (Rusek, 1965) comb. nov., O. subgranulosus (Gama, 1964) comb. nov., O. vornatscheri (Stach, 1946) comb. nov.]. Lectotypes are designated for O. anelli and O. vornatscheri. O. paucituberculatus (Stach, 1934) comb. nov., O. beroni (Gruia, 1972) comb. nov. and O. multisetis (Gruia, 1971) stat. & comb. nov. are transferred to the genus Onychiuroides after analysis of the original description. Onychiurus granulosus denticulatus Salmon, 1964 is junior synonym of O. granulosus (Stach, 1930). O. longisetosus (Stach, 1954) comb. nov. is regarded as “species inquirenda”. An identification key to all Onychiuroides species is provided.
Description of a new species of Dicyphus Fieber (Insecta: Heteroptera: Miridae) from Portugal based on morphological and molecular data
Authors: Cassis Gerasimos , Martinez-Cascales Jose Isidro , Sanchez Juan Antonio 
Published: March 2011

AbstractA new species of the plantbug genus Dicyphus (Insecta: Heteroptera: Miridae), D. umbertae Sanchez & Cassis sp. n., from Portugal is described and the closely related species, Dicyphus cerastii Wagner is redescribed. Several body measurements were taken. Male and female genitalia of both species are illustrated. D. umbertae was found in several localities in Central and South of Portugal on tomato (Lycopersicon esculentum Mill.) and Hyosciamus albus L. D. cerastii was found in southeast Spain on squash (Cucurbita maxima Duchesne), L. esculentum, Ononis natrix L., Withania frutescens (L.) Pauquy and H. albus. The external morphology of the two species is very alike and measurements overlap. In the two species the aedeagus has a similar pair of prominent slightly arcuate sclerites, but the shape and setae on the left paramere are different. Phylogenetic analyses were performed using 381 bp fragments of Cytochrome b. Other dicyphine species were used as outgroups in the analyses: Dicyphus tamaninii Wagner, D. rubicundus Blöte, D. escalerae Lindberg, Nesidiocoris tenuis (Reuter), Cyrtopeltis geniculata Fieber and Macrolophus sp. Several evolutionary models were explored under a maximum likelihood framework. The molecular analyses provided strong support for the species identity of the two sister species D. umbertae and D. cerastii.
The Patagonian species of the genus Atrichopogon Kieffer, with a biogeographic analysis based on Forcipomyiinae (Diptera: Ceratopogonidae)
Authors: Spinelli Gustavo , Marino Pablo , Posadas Paula 
Published: March 2011

AbstractThe following five new species of Atrichopogon Kieffer from southern Argentina and Chile are described and illustrated: A. aridus Spinelli & Marino, A. comechingon S. & M., A. endemicus S. & M., A. inacayali S. & M. and A. similis S. & M. A. aridus and A. comechingon also occur north of Patagonia. The previously known species A. obfuscatus Ingram & Macfie is redescribed, and notes on its type are provided. A key to recognition of males and females of the seven species inhabiting Patagonia is included. A biogeographic parsimony analysis of endemicity (PAE) interprets the relationships among the provinces of the southern South America. It is based on seven areas of endemism and distributional data of 30 species of the subfamily Forcipomyiinae. The analysis results in two most parsimonious cladograms and their strict consensus depicts the following relationships: ((Monte, Patagonian steppe) (Central Chile, Magellanic Moorland (Magellanic Forest, Maule, Valdivian Forest))).
Phylogeny and biogeography of the Australasian centipede Henicops (Chilopoda: Lithobiomorpha): A combined morphological and molecular approach
Authors: Colgan Donald , Edgecombe Gregory , Sharkey Deirdre 
Published: March 2011

AbstractThe lithobiomorph centipede Henicops is widely distributed in Australia and New Zealand, with five described species, as well as two species in New Caledonia and Lord Howe Island. Parsimony, maximum likelihood and Bayesian analyses of ca. 800 aligned bases of sequence data from 16S rRNA and 28S rRNA were conducted on a dataset including multiple individuals of Henicops species from populations sampled from different parts of species' geographic ranges, together with the allied henicopines Lamyctes and Easonobius. Morphological characters are included in parsimony analyses. Molecular and combined datasets unite species from eastern Australia and New Zealand to the exclusion of species from Western Australia, New Caledonia and Lord Howe Island. The molecular data favour these two geographic groupings as clades, whereas inclusion of morphology resolves New Caledonia, Lord Howe Island, southwest Western Australia and Queensland as successive sisters to southeastern Australia and New Zealand. The basal position of the Lord Howe Island species in the phylogeny favours a diversification of Australasian Henicops since the late Miocene unless the Lord Howe species originated in a biota that pre-dates the island. The molecular and combined data resolve the widespread morphospecies H. maculatus as paraphyletic, with its populations contributing to the geographic groupings New South Wales + New Zealand and Tasmania + Victoria.
