Gene flow from transgenic crops can introduce novel traits into related species, but the ecological importance of this process is unknown. Here, we report first empirical evidence that wild plants benefit a bacterial transgene under uncaged, natural conditions. Cultivated sunflower (Helianthus annuus) known to hybridize frequently with (H. in western and midwestern United States. We studied crop-developed Bacillus thuringiensis (Bt) transgene, cry1Ac, backcrossed populations. Lepidopteran...

Two new species of South American Glaresidae (Coleoptera: Scarabaeoidea) are described: Glaresis smithi Paulsen, from Argentina, and mondacai Chile Peru. The compared to their closest congener, fritzi Martínez et al., a key is provided for the known genus Erichson.

The endemic North American stag beetle tribe Platyceroidini Paulsen & Hawks (Coleoptera: Lucanidae: Lucaninae) is reviewed. All primary types were studied and the existing generic species concepts are subsequently corrected. Based on study of male genitalia external morphology, previously monotypic genus Platyceropsis Benesh reduced to subgeneric status under Platyceroides Benesh, new status, laticollis (Casey) keeni combination transferred this subgenus. Praocerus, subgenus, created...

Adults of three known species Ochodaeus Dejean (Coleoptera: Scarabaeoidea: Ochodaeidae) in Madagascar have a strongly granulate pronotum. Three new are described herein that smooth or weakly pronotum: modopunctatus, O . polypollicatus , and meandrus A key to the from is provided.

Three new species of Ochodaeus Dejean (Coleoptera: Scarabaeoidea: Ochodaeidae) from Madagascar are described that have a strongly granulate pronotum and, unlike all previously the country, possess clypeal tubercle or minute horn: O. meridialis , umbonulus and iniquipes . An update to key is provided.

The 1042 species of Scarabaeoidea known to occur in Peru are listed with their taxonomic placement families, subfamilies, and tribes.

Podolasia diabla Smith and Paulsen, new species parapilosa (Coleoptera: Scarabaeidae: Melolonthinae: Podolasiini) are described from dune habitats in Coahuila, Mexico. The illustrated, diagnostic characters discussed to separate them previously species. is notable as the first known this tribe with head horns.

This paper contains nomenclatural acts concerning the genus Nigidius MacLeay in stag beetle tribe Figulini Burmeister (Coleoptera: Lucanidae: Lucaninae). A revision of species obesus group results correction multiple problems. lectotype is designated for N. Parry, and identity helleri Boileau corrected. new , gravelyi Paulsen, described from Borneo. The synonymy larssoni de Lisle transferred to dawnae Gravely.

General confusion has surrounded the status of Nearctic Dorcus species since 19th Century. In this paper two are clarified and compared, morphological characters discussed that will readily distinguish them. Examination type specimens D. mexicanus reveals they actually mislabeled is a new synonym Palearctic parallelipipedus (L.).

The genus Chiasognathus Stephens is revised and now consists of seven species, all which are endemic to southern South America. genus-level names Bomansodus Chalumeau & Brochier, Carmeniella Molino-Olmedo, Ramireziella Molino-Olmedo confirmed be synonyms Chiasognathus. A new species described from the Biobio Region Chile. mniszechii Thomson removed synonymy a valid with schoenemanni Kriesche as its junior synonym. In order promote nomenclatural stability, lectotype designated for name...

The status of Platycerus cribripennis Van Dyke, generally treated as a synonym P. marginalis Casey, has been unclear. Here we recognize and redescribe cribripennis, which is endemic to the coastal mountains California, valid species due its unique morphology. A key California presented, distributions recognized are discussed.

Four species of stag beetles in the genus Sclerostomus Burmeister from southern South America (composing subgenera Chileistomus Weinreich and Sclerostomulus Weinreich) are redescribed: S. cucullatus (Blanchard), nitidus Benesh, tuberculatus (Solier), varasi Nagel. A key to American genera Lucanidae provided facilitate identification. The classification within is discussed. Nomenclatural problems resolved, generic concept fixed through a lectotype designation for type species, costatus...

The genus Sclerostomus Burmeister (Lucanidae: Lucaninae) of South America is redefined and restricted to species with a complex male genital capsule. Subgenera that lack this character are elevated generic status, including Altitatiayus Weinreich 5 species, Chileistomus 1 Sclerostomulus 2 species. These genera redescribed, new monotypic created for cannot be accommodated into these existing genera. subgenus Sclerostominus synonymized Sclerostomus. Three simple genitalic capsules transferred...

A new species of stag beetle, Nicagus occultus n. sp., is described from the Monahans Sandhills western Texas. Previously, genus contained only two species: N. obscurus (LeConte) eastern and central United States southern Canada, japonicus Nagel Japan. The discovery represents both an unexpected range extension unusual habitat (unvegetated sand dunes) for family Lucanidae. synopsis (diagnosis distribution) each given, including detailed distributional information obscurus.

The Ochodaeidae (Coleoptera: Scarabaeoidea) of Argentina are revised. Previously, two species Ochodaeinae were known from the country, both in genus Parochodaeus Nikolajev: P. campsognathus (Arrow) and cornutus (Ohaus). An additional 7 described here as new. In addition, Gauchodaeus patagonicus, new subfamily Chaetocanthinae, is described. This first record Chaetocanthinae South America. Redescriptions, diagnoses, maps provided for each species. We also provide a key to genera Argentina....

We examine the taxonomic placement of South American stag beetles tribe Ceratognathini Sharp, 1899 that were previously placed in genus Ceratognathus Westwood. compared species with specimens from 13 Australasian using morphological characters legs, mandibles, genitalia, and elytra. Based on generic limits proposed by Holloway for Ceratognathini, differ three genera (Ceratognathus, Mitophyllus Parry, Holloceratognathus Nikolajev) sufficiently to establish a new genus, Hilophyllus n. gen. The...

Abstract The evolution of island systems is characterized by processes that result in extreme morphological diversity, high endemism and extinction rates. These dynamics can make phylogenetic reconstruction difficult, i.e. the extinct flightless Dodo from Mauritius was assigned to family doves only through DNA analysis subfossils. Many insect species on islands have gone habitat loss, face similar challenges decipher their evolutionary history, however historical specimens not yet been...

Ten new species in the Phyllophaga Harris subgenus Cnemarachis Saylor (Coleoptera: Scarabaeidae: Melolonthinae: Melolonthini) were discovered during a May 2013 field expedition Cuba. These are (Cnemarachis) andersoni Smith and Paulsen, bretti calai deleri falcata holguinensis manibota perfidia sarlacca secessicola Paulsen. Each is described, illustrated, diagnosed.
