CLASSIFICATION, PHYLOGENY, AND ZOOGEOGRAPHY OF SCHIZOGENIUS PUTZEYS (COLEOPTERA: CARABIDAE: SCARITINI)* DONALD R. WHITEHEAD Department of Entomology University of Alberta Quaestiones entomologicae Edmonton 7, Alberta 8 : 131-348 1972 North and Middle American species of Schizogenius Putzeys are reviewed in detail, and South American species are treated provisionally. The genus is redefined, characterized, and illustrated. Two subgenera are Genioschizus new subgenus, with three species groups, and Schizogenius s. str., with 21 species groups. In all, I recognize 68 species and two subspecies. Keys are given to: subgenera; described species groups, species, and subspecies of Genio­ schizus; same of North and Middle American Schizogenius s. str.; and species groups and most described species of South American Schizogenius s. str. / describe as new the following 27 taxa: S. crenulatus chiapatecus, S. sculptilis, S. im- puncticollis, S. suturalis, S. jacarensis, S. bicolor, S. cearaensis, S. negrei, S. costipennis, S. reichardti, S. ocellatus, S. lindrothi, S. brevisetosus, S. seticollis vandykei, S. plurisetosus, S. kulti, S. dilatus, S. tibialis, S. ozarkensis, S. planuloides, S. neovalidus, S. chiricahuanus, S. pacificus, S. emdeni, S. scopaeus, S. falli, and S. ochthocephalus. Synonymies proposed for the first time are: S. peninsularis Van Dyke (= S. auripennis Bates), S. angusticollis Putzeys (= S. arechavaletae Putzeys), S. validus Fall (= S. longipennis Putzeys), and S. championi Kult (= S. pygmaeus Van Dyke). Given for each species are, as appropriate: synonymic list, diagnostic combination, de­ scription, discussion of variation, etymological derivation, geographic distribution list, col­ lecting notes, taxonomic notes, and illustrations of important structural characteristics. Geographic distributions are mapped for all North and Middle American species. Descrip­ tions of most North and Middle American species are augmented with tables of descriptive statistics. Results of detailed statistical analyses of geographic variation for members of some North and Middle American species groups are tabulated, mapped, and discussed. A phytogeny is reconstructed for the genus, and carefully integrated with historical zoo­ geography. No geographic evidence is used to reconstruct the phytogeny of major groups and lineages; phytogenies derived from contrasting phyletic and phenetic techniques are favorably compared. To derive the phytogeny of members of the truquii lineage, which includes most North and Middle American species of Schizogenius, use of zoogeographic evidence is essential; simple cladistic techniques are not used because character states of too many characteristics are reversible. An average time between dichotomies in the recon­ structed phytogeny of Schizogenius is about 3,000,000 years. This interval is used to inte­ grate Schizogenius phytogeny and zoogeography. On the same basis, phytogenies and zoo­ geographies of Brachinus and Evarthrus are compatible. Zoogeographies o/Brachinus, Evar- thrus, and Schizogenius are compared for North and Middle American faunas. Ancestral Schizogenius evolved in South America about Middle Eocene. Ancestors of the ferrugineus group, the truquii lineage, and the crenulatus group entered North America in Late Eocene, Middle Oligocene, and Middle Miocene. The ancestor of the truquii lineage ultimately evolved into eight species groups, and their evolutionary zoogeographies are dis­ cussed in detail. Since Early Pleistocene, members of the tenuis, optimus, and lindrothi groups have crossed the Panamanian land bridge to Middle America, and members of the depressus group have spread southward into South America. * Revised version of thesis submitted to the Faculty of Graduate Studies and Research in partial fulfillment of require­ ments for the degree of Doctor of Philosophy at the University of Alberta.

El genero es redefinido, senalado, e ilustrado. Dos subgeneros son el Genioschizus, subgenero nuevo, con tres grupos de especies; y el Schizogenius s. str., con 21 grupos. En total, yo reconozco 68 especies y dos subespecies. Se han ofrecido claves para los subgeneros, grupos de especies, especies, y subespecies del Genioschizus; lo mismo que para el Schizogenius s. str. de Norte y Centro America, asi como para los grupos de especies, y la mayor parte de las especies descritas en Sur America. Yo describo como nuevos los siguientes: S. crenulatus chiapatecus, S. sculptilis, S. impunc- ticollis, S. suturalis, S. jacarensis, S. bicolor, S. cearaensis, S. negrei, S. costipennis, S. reich- ardti, S. ocellatus, S. lindrothi, S. brevisetosus, S. seticollis vandykei, S. plurisetosus, S. kulti, S. dilatus, S. tibialis, S. ozarkensis, S. planuloides, S. neovalidus, S. chiricahuanus, S. pacifi- cus, S. emdeni, S. scopaeus, S. falli, y S. ochthocephalus. Son sinonimias nuevas: S. penin- sularis Van Dyke (= S. auripennis Bates), S. angusticollisPutzeys (= S. arechavaletae Putzeys), S. validus Fall (= S. longipennis Putzeys), y S. championi Kult (= S. pygmaeus Van Dyke). Para cada especie se ha ofrecido, como conviene: lista de sinonimias, combination de diagnostico, descripcion, discurso de variation, derivation etimologica, lista de localidades, notas sobre coleccion y taxonomia, e ilustraciones de caracteristicas esenciales. Igualmente se dan cartas de distribution para las especies de Norte y Centro America. Las especies de Norte y Centro America han sido provistas, en su description, con tablas de estadisticas descriptivas; y los resultados de andlisis estadisticos detallados, son catalogados, delineados en cartas, y discutidos. Se ha reconstruido una filogenia para el genero, y, cuidadosamente, se ha integrado esta con una zoogeografla historica. No se ha usado ninguna evidencia geogrdfica para la recons­ truction de la filogenia de grupos y los linajes mayores; las filogenias derivadas de tecnicas fileticas y feneticas son comparadas favorablemente. Para derivar la filogenia de miembros del linaje truquii, que contiene la mayor parte de las especies del Schizogenius de Norte y Centro America, el uso de evidencia zoogeogrdfica es indispensable. No se han usado tecni­ cas feneticas sencillas debido a que los estados de cardcter con demasiadas caracteristicas, son reversibles. Un intervalo proporcional entre dicotomias en la filogenia reconstruida del Schizogenius se aproxima a los 3,000,000 de anos. Este intervalo es usado para integrar la filogenia con la zoogeografla del Schizogenius. Igualmente, las filogenias y zoogeografias del Brachinus y el Evarthrus son compatibles. Las zoogeografias del Brachinus, el Evarthrus, y el Schizogenius son comparadas para las faunas de Norte y Centro America. El Schizogenius ancestral se desarrollo en Sur America alrededor del Eoceno Medio. Los predecesores del grupo ferrugineus, del linaje truquii, y del grupo crenulatus, penetraron en Norte America durante el Eoceno Ultimo, Oligoceno Medio, y Mioceno Medio. El predece- sor del linaje truquii finalmente desarrollado en ocho grupos de especies, y sus zoogeografias evolutivas son discutidos en detalle. Desde el Pleistoceno Primario, miembros de los grupos tenuis, optimus, y lindrothi han atravesado el puente de tierra de Panama hacia Centro America, y miembros del grupo depressus se han distribuido en el interior de Sur America.

This is unfortunate since as a result no other aspects of their biologies have been studied, but fortunate in that comparatively few taxonomic errors have been introduced into the literature. Lindroth (1961) wrote a fine revision of the Canadian and Alaskan members of this fascinating group of beetles. His treatment of Schizogenius, the subject of my investiga­ tions, is excellent for the limited Canadian fauna but is not adequate to identify specimens from most regions in the United States. The genus, after all, is mainly Neotropical, and in fact a good taxonomy for it must be based on the entire fauna. Except for Lindroth's (1961) key to described species from America north of Mexico, the most recent full revisions of Schizo­ genius were done by Putzeys (1866) for Mexico and southward, and by LeConte (1879) for America north of Mexico. How much is known about these beetles? Since Thomas Say named the first species in 1823, little more than descriptive morphological work has been done. Immature stages remain completely unknown, and aside from collector's notes on habitat we have no in­ formation on adult biology. The earliest names for species now placed in Schizogenius were proposed by Say (1823), Castelnau (1835), and Haldeman (1843). Putzeys (1846) intro­ duced the generic name Schizogenius, and in this and subsequent

  • A Genus-Level Supertree of Adephaga (Coleoptera) Rolf G
    ARTICLE IN PRESS Organisms, Diversity & Evolution 7 (2008) 255–269 www.elsevier.de/ode A genus-level supertree of Adephaga (Coleoptera) Rolf G. Beutela,Ã, Ignacio Riberab, Olaf R.P. Bininda-Emondsa aInstitut fu¨r Spezielle Zoologie und Evolutionsbiologie, FSU Jena, Germany bMuseo Nacional de Ciencias Naturales, Madrid, Spain Received 14 October 2005; accepted 17 May 2006 Abstract A supertree for Adephaga was reconstructed based on 43 independent source trees – including cladograms based on Hennigian and numerical cladistic analyses of morphological and molecular data – and on a backbone taxonomy. To overcome problems associated with both the size of the group and the comparative paucity of available information, our analysis was made at the genus level (requiring synonymizing taxa at different levels across the trees) and used Safe Taxonomic Reduction to remove especially poorly known species. The final supertree contained 401 genera, making it the most comprehensive phylogenetic estimate yet published for the group. Interrelationships among the families are well resolved. Gyrinidae constitute the basal sister group, Haliplidae appear as the sister taxon of Geadephaga+ Dytiscoidea, Noteridae are the sister group of the remaining Dytiscoidea, Amphizoidae and Aspidytidae are sister groups, and Hygrobiidae forms a clade with Dytiscidae. Resolution within the species-rich Dytiscidae is generally high, but some relations remain unclear. Trachypachidae are the sister group of Carabidae (including Rhysodidae), in contrast to a proposed sister-group relationship between Trachypachidae and Dytiscoidea. Carabidae are only monophyletic with the inclusion of a non-monophyletic Rhysodidae, but resolution within this megadiverse group is generally low. Non-monophyly of Rhysodidae is extremely unlikely from a morphological point of view, and this group remains the greatest enigma in adephagan systematics.

    30 THE GREAT LAKES ENTOMOLOGIST Vol. 42, Nos. 1 & 2 An Annotated Checklist of Wisconsin Ground Beetles (Coleoptera: Carabidae) Peter W. Messer1 Abstract A survey of Carabidae in the state of Wisconsin, U.S.A. yielded 87 species new to the state and incorporated 34 species previously reported from the state but that were not included in an earlier catalogue, bringing the total number of species to 489 in an annotated checklist. Collection data are provided in full for the 87 species new to Wisconsin but are limited to county occurrences for 187 rare species previously known in the state. Recent changes in nomenclature pertinent to the Wisconsin fauna are cited. ____________________ The Carabidae, commonly known as ‘ground beetles’, with 34, 275 described species worldwide is one of the three most species-rich families of extant beetles (Lorenz 2005). Ground beetles are often chosen for study because they are abun- dant in most terrestrial habitats, diverse, taxonomically well known, serve as sensitive bioindicators of habitat change, easy to capture, and morphologically pleasing to the collector. North America north of Mexico accounts for 2635 species which were listed with their geographic distributions (states and provinces) in the catalogue by Bousquet and Larochelle (1993). In Table 4 of the latter refer- ence, the state of Wisconsin was associated with 374 ground beetle species. That is more than the surrounding states of Iowa (327) and Minnesota (323), but less than states of Illinois (452) and Michigan (466). The total count for Minnesota was subsequently increased to 433 species (Gandhi et al. 2005). Wisconsin county distributions are known for 15 species of tiger beetles (subfamily Cicindelinae) (Brust 2003) with collection records documented for Tetracha virginica (Grimek 2009).

Coleoptera, Carabidae, exposed riverine sediments, pitfall trap, sandbar, effi ciency, psammophilous, riparian Abstract. Exposed riverine sediments are unique riparian environments that exhibit high biodiversity and harbor many specialist species. Ground beetles are the most well studied inhabitants within these environments where they are often sampled using pitfall traps. In order to develop conservation measures for species occupying these habitats a logical fi rst step is to refi ne sam- pling methods so that proper biodiversity assessments can be carried out. To that end, the effectiveness of two pitfall trap designs (standard trap vs. barrier trap) was evaluated. Over three sampling periods we collected 5,186 individuals represented by 43 spe- cies. Barrier traps proved to be superior, yielding signifi cantly greater numbers of individuals (n = 3,456 vs. 1,730) than standard traps. Additionally, we collected more ground beetle species (37 vs. 30) in barrier traps than in standard pitfall traps. This study supports the rationale for deployment of more than one trap design to avoid defi ciencies exhibited by a single type.
