This book was released on 1986-01-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cladistic analysis based on internal male female reproductive characters and external characters is used to group exemplar taxa in the carabid tribe Platynini. A classification, key to genera in North America, and a key to species groups of Agonum in North America north of Mexico are presented. The Agonum extensicolle species group comprises seven species: A. cyanope (Bates); A. extimum Liebherr, n.sp.; A. parextimum Liebherr n. sp.; A. texanum (LeConte); A. extensicolle (Say); A. decorum (Say); A. elongatulum (Dejean). Analyses of infraspecific geographic variation show: 1 ) A. texanum is biometrically uniform over the center of its range whereas individuals from outlying populations deviate in several measurements; 2) A. extensicolle is a variable species, with clinal changes in biometry and color ocurring across its range; 3) A. decorum is polymorphic for color and setation, and clinally variable in biometric characters. Across the group, flight apparatus development is inversely correlated with the amount of genetic heterogeneity measured by starch-gel electrophoresis. Electrophoretic, qualitative morphological, and biometric data are used to estimate phylogenetic relationships in the A. extensicolle group. The electrophoretic and morphological data produce compatible estimates of phylogeny. The biometric data are incompatible with the other data and are judged less useful for estimation of affinities. Distributional data are utilized in conjunction with the proposed phylogeny to investigate speciation events in the group. The principal mechanism is allopatric speciation brought about by vicariance across the lowlands of southeastern Arizona; the Cochise filter barrier. A second pattern involves a peripheral isolate of Antillean stock diverging on the Florida peninsula. A third speciation event involves a habitat shift in which a lowland desert form produced a species which now inhabits the pine-oak zone in the Sierra Madre Occidental. The area-taxon relationships are compared with those in other groups. Based on an electrophoretic clock calibrated using data from Drosophila, the timing of the initial speciation event in the group is estimated at 6-12 million years b.p. Other speciation events occurred throughout the Pliocene and Pleistocene, with the most recent divergence of A. decorum and A. elongatulum estimated at less than two million years b.p.

Download or read book Phylogeny and Revision of the Anchomenus Clade written by James Kenneth Liebherr and published by . This book was released on 1991 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Taxa comprising the Anchomenus clade within the carabid tribe Platynini, subtribe Platyni, possess the synapomorphy of a female spermatheca with a basal reservoir and a long apical filament. As presently constituted, this clade comprises 29 species arrayed in four genera; the monotypic Tetraleucus Casey in eastern North America, the Holarctic Anchomenus Bonelli with 10 species, the Holarctic Sericoda Kirby with 7 species, and the Mexican Elliptoleus Bates with 11 species. Seven species are newly described; Anchomenus capensis, n. sp. from Baja California Sur, Sericoda montana, n. sp. from Cuba, Elliptoleus corvus, n. sp. from México state, Elliptoleus zapotecorum, n. sp. from Oaxaca, Elliptoleus whiteheadi, n. sp. from Guerrero, Elliptoleus balli, n. sp. from Jalisco and Michoacan, and Elliptoleus tequilae, n. sp. from Jalisco. New combinations proposed include: Tetraleucus picticornis Newman (removed from Agonum Bonelli); Anchomenus virescens Motschulsky (removed from Chlaeniomimus Semenow, 1889, as that generic name is a new synonym of Anchomenus Bonelli, 1810); Anchomenus yukihikoi (removed from Agonum (Nipponanchus) Habu, 1978, as that subgeneric name is a new synonym of Anchomenus); Sericoda ceylonica (removed from Agonum Bonelli), and Sericoda lissoptera (removed from Anchomenus Bonelli). Species-level names placed into synonymy within Anchomenus, followed by their respective senior synonyms, include: Dohrni diana Sahlberg = dohrnii Fairmaire, discophorus Chaudoir = dorsalis Pontoppidan, cyaneus asturicus Heinz = cyaneus Dejean, gracilicollis Jakowleff = virescens Motschulsky. Batenus? borealis Motschulsky is removed from synonymy under Sericoda bogemannii, and is recognized as a junior synonym of Agonum consimile Gyllenhal. Lectotypes are designated for Anchomenus dohrnii diana Sahlberg, Anchomenus virescens Motschulsky, A. leucopus Bates, A. funebris LeConte, Sericoda lissoptera Chaudoir, S. ceylonica Motschulsky, Elliptoleus acutesculptus Bates, E. olisthopoides Bates, E. curtulus Bates, E. vixstriatus Bates, E. luteipes Csiki, and E. crepericornis Bates. A cladistic hypothesis of the phylogenetic relationships among the species is formulated based on 65 potential synapomorphies of adults, represented by 54 characters. The genera Sericoda and Elliptoleus are hypothesized as sister genera, with Anchomenus their sister group. Tetraleucus is the outgroup for the rest of the clade. The amount of character evolution is heterogeneous across the clade, with significantly less anagenetic change per internode of the cladogram within Elliptoleus compared to its sister group Sericoda. Elliptoleus species possess limited powers of dispersal and exhibit very restricted geographic ranges, whereas Sericoda species readily fly and possess some of the largest geographic ranges observed within Carabidae. Thus, relatively less anagenetic change is associated with speciation in the less vagile more endemic Elliptoleus, and extensive anagenesis occurs during the history of the vagile, widespread Sericoda species. First-instar larvae of 6 of the 29 species are described, and a cladistic hypothesis of relationships based on six larval characters is proposed. This hypothesis supports the monophyly of the sister genera Sericoda and Elliptoleus, but is otherwise discordant with the cladistic hypothesis based on adult characters. Autapomorphies of the first-instar larvae of the six taxa are listed in order to facilitate comparison of derived states in newly discovered larvae. The biogeographic patterns within the individual genera are analyzed using cladistic biogeographic methodology. The entire clade is hypothesized as Eocene in age, with the basal taxon Tetraleucus isolated from Old World progenitors of the rest of the clade due to amphi-Atlantic vicariance. Anchomenus is divisable into two clades; four New World species distributed along the Pacific coast from Alaska to Baja California, and six Old World species distributed from Japan to western Europe. Beringian vicariance in the Miocene is the likely cause of this pattern. Sericoda species exhibit a collective Holarctic distribution, with one species found in montane regions of southeast Asia and Indomalaya. Beringian vicariance has occurred at least twice during the diversification of the seven species leading to divergence of: (1) S. ceylonica from its sister group of S. bembidioides plus S. montana, (2) the sister species S. bogemannii and S. obsoleta. These vicariant events are hypothesized to have occurred in late Miocene or Pliocene times. Elliptoleus was probably isolated in México from its more northern sister group, Sericoda, in late Miocene. Cladistic biogeographic analysis allows derivation of a fundamental area cladogram for the temperate humid montane forest habitats occupied by Elliptoleus species. The Sierra Madre Occidental is hypothesized as the sister area of the Transvolcanic Sierra plus the more southerly Sierra de Oaxaca and Sierra Madre del Sur. Biotic connections of the Transvolcanic Sierra with montane regions to the south are via a filter bridge along the Atlantic versant, running from Pico de Orizaba to the Sierra de Oaxaca. Divergence events at the species level are geographically associated with river valleys, or regions of geological uplift near major volcanoes"--P. 5.

This book was released on 2020 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: The genera Psalistops Simon, 1889, Trichopelma, Simon, 1888 and Cyrtogrammomma Pocock, 1895 are revised and included in cladistics analyses including almost all species of these genera. In order to test previous morphological hypotheses on the relationships of Barychelidae, Paratropididae and Theraphosidae and because of the controversial taxonomic position of Psalistops and Trichopelma, a set of terminal taxa representing all subfamilies of Paratropididae (Paratropidinae, Glabropelmatinae), Barychelidae (Barychelinae, Sasoninae, Trichopelmatinae) and most theraphosid subfamilies were included, as well as a diplurid, a nemesiid, and a pycnothelid, the later used to root the cladogram. The matrix with 66 terminal taxa, 2 continuous and 93 discrete characters was analysed with TNT 1.5. We found that Trichopelmatinae is not a monophyletic group, and Psalistops is transferred to Theraphosidae, as well as the barychelid genus Cyrtogrammomma and the paratropidid genus Melloina Brignoli. Cyrtogrammomma was retrieved as the sister group of Trichopelma, and Melloina as the sister group of Holothele Karsch. Psalistops was retrieved as the sister group of Reichlingia Rudloff, and the clade with these two genera is the most basal in Theraphosidae. Barychelidae was found to be monophyletic and the sister group of Theraphosidae. Paratropididae was retrieved as the sister group of Barychelidae + Theraphosidae. The relationship and possible synapomorphies of the three families are herein discussed. This is the first time since Raven (1985) that representatives of all barychelid (Barychelinae, Sasoninae, Trichopelmatinae), paratropidid (Paratropidinae, Glabropelmatinae) and most theraphosid subfamilies have been included in a morphological cladistic analysis. Psalistops comprises two species, P. melanopygius Simon, 1889 (type species) and P. colombianus sp. nov. Psalistops montigena Simon, 1889, P. tigrinus Simon, 1889 and P. zonatus Simon, 1889 are synonymized with P. melanopygius Simon, 1889. Psalistops fulvus Bryant, 1948, P. hispaniolensis Wunderlich, 1988 (fossil), P. maculosus Bryant, 1948, P. venadensis Valerio, 1986 and P. steini (Simon, 1889) are transferred to Trichopelma. Psalistops gasci Maréchal, 1996 is transferred to Hapalopus Ausserer (Theraphosidae); P. opifex (Simon, 1889) and P. solitarius (Simon, 1889) are transferred to Schismatothele Karsch, 1879 (Theraphosidae). Schismatothele solitarius (Simon, 1889) n. comb. is synonymized with Schismatothele lineata Karsch, 1879, n. syn. Psalistops nigrifemuratus Mello-Leitão, 1939 is probably a nemesiid or pycnothelid, and herein considered as nomen dubium in Pycnothelidae. Trichopelma comprises 22 species: Trichopelma nitidum Simon, 1888 (type species), T. coenobita (Simon, 1889), T. steini (Simon, 1889), T. affine (Simon, 1892), T. cubanum (Simon, 1903), T. maculatum (Banks, 1906), T. zebra (Petrunkevitch, 1925), T. banksia Özdikmen & Demir, 2012, T. insulanum (Petrunkevitch, 1926), T. fulvus (Bryant, 1948) n. comb., T. laselva Valerio, 1986, T. venadensis (Valerio, 1986) n. comb., T. huffi sp. nov., T. gabrieli sp. nov., T. tostoi sp. nov., T. goloboffi sp. nov., T. juventud sp. nov., T. laurae sp. nov., T.bimini sp. nov., T. loui sp. nov., T. platnicki sp. nov., and T. hispaniolensis Wunderlich, 1988 n. comb. (fossil). Trichopelma maculosus (Bryant, 1948) n. comb. is synonymized with P. fulvus Bryant, 1948; T. corozalis (Petrunkevitch, 1929) is synonymized with T. insulanum (Petrunkevitch, 1926). Trichopelma astutum Simon, 1889 is transferred to Euthycaelus Simon, 1889, and T. maddeni Esposito & Agnarsson, 2014 to Holothele Karsch, 1879 (Theraphosidae). Trichopelma flavicomum Simon, 1891 is transferred to Neodiplothele (Barychelidae, Sasoninae). The species T. illetabile Simon, 1888, T. spinosum (Franganillo, 1926), T. scopulatum (Fischel, 1927) and T. eucubanum Özdikmen & Demir, 2012 are considered as nomina dubia. Cyrtogrammomma comprises two species: C. monticola Pocock, 1895 (type species) and C. raveni sp. nov. Keywords: Araneae, cladistic analysis, Melloina, Mygalomorphae, Reichlingia, Trichopelmatinae"--Page 4.

This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The present study examines the rhyparochromine tribe Myodochini at the generic level on a world basis. A key to 56 genera is provided and diagnoses and brief summary descriptions of salient morphological features are given for all genera. Thirteen new genera (Ashlockaria, Bacacephalus, Ereminellus, Froeschneria, Humilocoris, Megacholula, Neopamera, Paracholula, Paraparomius, Pseudoparomius, Slaterobius, Stalaria, and Stridulocoris) and the new species Megacholula englemani are described. The following new synonymies are made: Exptochiomera with Prytanes; Neocattarus with Cholula; Sphaerobius with Erlacda; and Sphaerobius gracilis with Erlacda arhaphaeoides. New combinations include: Ashlockaria sobrius; Bacacephalus globiceps; Cholula firmus, C. irrorandus, C. maculatus, C. parvus, C. vigens; Ereminellus arizonensis; Froeschneria infumatus, F. multispinus, F. oblitus, F. piligerus, F. vicinalis; Horridipamera bergrothi, H. ebenaui, H. inconspicuus, H. perlongus, H. pullatus, H. rusticus, H. spinicrus, H. subsericeus; Humilocoris cephalotes; Ligyrocoris occultus; Neopamera albocinctus, N. bilobata, N. brachialis, N. costalis, N. crassicornis, N. honduranus, N. insularis, N. intermedius, N. mumfordi, N. neotropicalis, N. paganus, N. platanus, N. procerulus, N. recinctus, N. serripes, N. sororculus, N. tineodes, N. tuberculatus, N. vicarius, N. vividus; Orthaea consuta, O. procinctus ; Pamerana punctulatus, P. scotti, P. sinae; Paracholula thoracicus, P. vegetus; Paraeucosmetus albofasciatus, P. crassiceps, P. gemmatus, P. harimaensis, P. malayus, P. mimulus, P. nervosus, P. sladeni, P. vitalisi, Paraparomius lateralis, P. leptopoides; Paromius limbatus; Prytanes albomaculata, P. caeca, P. confusa, P. dissimilis, P. foeda, P. formosa, P. fusicornis, P. intercisa, P. minima, P. oblonga, P. plebeius, P. tumens; Pseudopachybrachius basalis, P. capicolus, P. nesovinctus, P. pacificus, P. reductus, P. undulatus, P. vinctus; Pseudopamera ater, P. institius, P. setosa; Pseudoparomius linearis; Remaudiereana africana, R. andrewsi, R. annulipes, R. boninensis, R. castanea, R. flavipes, R. horvathi, R. inornatus, R. kydippe, R. nigra, R. nigriceps, R. noctuabundus, R. octonotata, R. puberulus, R. robustus, R. sidnicus, R. sobrina, R. tibialis; Slaterobius insignis, S. quadristriatus; Stalaria ferruginosus, S. kisseis, S. nysias; Stigmatonotum afrus, S. geniculatus; Stridulocoris gracilis. A cladistic analysis of the myodochine genera is presented with emphasis on the valuable character system of the male genitalia. Plesiomorphic and apomorphic states are designated for all characters employed, and only synapomorphic character states are employed to infer relationship and to construct a generic cladogram for the tribe Myodochini. The phylogeny shown in the cladogram is viewed against the current known distributions of the various living myodochine species and used to propose a broad zoogeographic hypothesis about the origins of the tribe and major monophyletic assemblages within the Myodochini. Almost total lack of transoceanic sister groups at the generic level suggests a post-Gondwanaland origin and evolution for the tribe, and the distributional patterns also attest to the isolated evolution of two major lineages in North America"--P. 49.

Available in PDF, EPUB and Kindle. Book excerpt: The Carabidae form one of the largest and best studied families of insects, occurring in nearly every terrestrial habitat. The contributions included in this book cover a broad spectrum of recent research into this beetle family, with an emphasis on various aspects of ecology and evolution. They deal both with individual carabid species, for example in studies on population and reproductive biology or life history in general, and with ground beetle communities, as exemplified in papers treating assemblages in natural habitats, on agricultural land and in forests. Disciplines range from biogeography and faunistics, over morphology, taxonomy and phylogenetics, ecophysiology and functional ecology, to population, community, conservation and landscape ecology. This volume is the result of the 8th European Carabidologists' Meeting, 2nd International Symposium of Carabidology, September 1-4, 1992, Belgium.

Download or read book Cladistic Biogeography written by Christopher J. Humphries and published by OUP Oxford. This book was released on 1999-04-15 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution and classification of life on earth has long been of interest to biological theorists, as well as to travellers and explorers. Cladistic biogeography is the study of the historical and evolutionary relationships between species, based on their particular distribution patterns across the earth. Analysis of the distributions of species in different areas of the world can tell us how those species and areas are related, what regions or larger groups of areas exist, and what their origins might be. The first edition of Cladistic Biogeography was published in 1986. It was a concise exposition of the history, methods, applications of, and prospects for cladistic biogeography. Well reviewed, and widely used in teaching, Cladistic Biogeography is still in demand, despite having been out of print for some time. This new edition draws on a wide range of examples, both plant and animal, from marine, terrestrial, and freshwater habitats. It has been updated throughout, with the chapters being rewritten and expanded to incorporate the latest research findings and theoretical and methodological advances in this dynamic field.
