A new Mexican species of Ochraethes Chevrolat, 1860 (Coleoptera, Cerambycidae, Cerambycinae, Clytini) is described: Ochraethes skillmani Wappes, Santos-Silva and Botero. Plocaederus mirim Martins and Monné, 2002 (Cerambycini) is redescribed and its female is figured for the first time. New geographical records in Plocaederus Dejean, 1835 are also provided.
A taxonomic revision of Panamanian species of the genus Dasymutilla Ashmead (Hymenoptera, Mutillidae) is presented and a key for the six species is given, all recognized from both sexes. Dasymutilla colorado Cambra, Williams and Quintero sp. nov., from central and eastern Panama, is described and illustrated. Sex associations permitted us to make the following five synonymies: D. sleipniri Manley and Pitts, 2007 (male) under D. phya (Cameron, 1895) (female); D. deyrollesi Mickel, 1937 (male) and Sphaerophthama [sic.] temaxensis Cameron, 1895 under Dasymutilla araneoides (Smith, 1862) (female); D. ionothorax Manley and Pitts, 2007 (male) under Dasymutilla spilota Manley and Pitts, 2007 (female); and D. guanacaste Manley and Pitts, 2007 (male) under D. paradoxa (Gerstaecker, 1874) (female). Seasonal flight activity for Dasymutilla from six years of continuous malaise trappings in Barro Colorado Island is presented.
An early, overlooked description of the genus Atelodesmis (Coleoptera, Cerambycidae, Lamiinae) is attributed to Chevrolat (in Duponchel and Chevrolat 1841), with A. mannerheimii Duponchel and Chevrolat, 1841 as its type species, and the genus redescribed. Atelodesmis Buquet, 1857, is a junior synonym and primary homonym of Atelodesmis Chevrolat. Atelodesmis hirticornis Buquet, 1857 and A. vestita Buquet, 1857 are synonymized with A. mannerheimii. Fallaxdesmis is described as a new genus with Atelodesmis unicolor Buquet, 1857 as type species. Atelodesmis piperita Bates, 1855 is transferred to Eupogonius and newly recorded for the state of Oaxaca, Mexico. A new species for Mexico and Guatemala, Eupogonius giesberti, is described. The following new combinations are established: Fallaxdesmis unicolor (Buquet, 1857) and Eupogonius piperita (Bates, 1855). Illustrations of A. mannerheimii, Fallaxdesmis unicolor, and the holotypes of A. hirticornis, A. vestita, A. unicolor, A. piperita and Eupogonius giesberti are included.
A new cryptic species, Aleochara (Xenochara) castaneimarmotae Klimaszewski, Webster, and Brunke, new species (Coleoptera: Staphylinidae: Aleocharinae), associated with Marmota monax (Linnaeus) burrows and caves in eastern North America, is described and illustrated. A key to Canadian species of subgenus Xenochara Mulsant and Rey and revised distributions of the taxonomically difficult fumata species group are provided. Aleochara quadrata Sharp is recorded from Washington and Oregon for the first time.
This paper revises the genus Ganelius Benesh, which is endemic to Madagascar, in the stag beetle tribe Figulini Burmeister (Coleoptera: Lucanidae: Lucaninae). Species in the genus are striking in their highly sexually dimorphic mandibles, a character that rarely occurs in the tribe. The genus was previously comprised of four species, but three of these names were problematic or questionably applied. A lectotype is designated for G. madagascariensis Laporte, a neotype is designated for Ganelius oberndorferi Nonfried, and Nigidius passaliformis Benesh is newly synonymized with G. oberndorferi. Two new species, G. gnamptus Paulsen and G. zombi Paulsen, are described from western Madagascar. The identity of the overlooked Ganelius nageli (Kriesche) is fixed through a neotype designation, and the species is moved to the new genus Agnelius, which is distinguished from Ganelius by a lack of sexual dimorphism, serrate protibiae, and a more flattened body.
Adesmus martinsi (Coleoptera, Cerambycidae, Lamiinae, Hemilophini), a new species from Bolivia, is described, illustrated, and included in a previous key. The new species displays gender dimorphism in the pubescent pattern and in anatomical structure. Thus, Adesmus becomes the second genus recorded in the Hemilophini to have visual chromatic dimorphism.
Lantana camara L., considered among the world’s worst invaders is in identity crisis and contentiously referred as Lantana camara L. (sensu lato). Taxonomic ambiguity in L. camara L. (sensu lato), a species complex is one of the grim caveats behind incompetence of its management efforts. Recognizing the extent of variability within the complex, we aim to highlight the need to circumscribe its composition to bring effective management and control efforts into practice. There is a need for clear terminology to examine weedy, naturalized and/or invasive complex constituents that have been placed under the contentious umbrella of 'L. camara L. (sensu lato)'. The time is ripe for invasion ecologists, cytogeneticists and conservationists to collaboratively focus on disentangling the complex and integrate their knowledge and expertise into management and control programs.
Two new genera and species of tiger beetles from Baltic amber (Coleoptera: Carabidae: Cicindelinae)
(2017)
Two fossil tiger beetle species (Coleoptera, Carabidae, Cicindelinae) are described from Eocene Baltic amber using light microscopic and X-ray microscopic techniques. Both species are considered representatives of the subtribe Iresina Rivalier, 1971 due to the shared combination of character states: glabrous head, six labral and four suborbital setae, and glabrous pronotum. Palaeopronyssiformia groehni Wiesner, Will, and Schmidt, new genus, new species, is characterized by a glabrous and furrowed head with six labral setae, large eyes, presence of two supraorbital setae on each side, mandibles with two teeth of the incisor region, and a glabrous and furrowed pronotum. Palaeoiresina cassolai Wiesner, Will, and Schmidt, new genus, new species, is characterized by a unicolored, undentated labrum, mandibles with two teeth of the incisor region, glabrous head with six labral setae, two clypeal setae, two supraorbital setae on each side, and a glabrous pronotum, mesepisternum, mesepimeron, and metepisternum. The species described here represent the only known tiger beetle fossils preserved in Baltic amber.
New Bolivian Rhinotragini (Coleoptera, Cerambycidae, Cerambycinae) are described: three species of Phygopoda Thomson, 1864 (P. longiscopifera sp. nov., P. boliviensis sp. nov. and P. chaquensis sp. nov.); and one species of Phygopoides Peñaherrera-Leiva and Tavakilian, 2007 (P. maxwelli sp. nov.). Two Brazilian species of Neophygopoda Melzer, 1933 are transferred to the genus Phygopoda: P. exilis (Melzer, 1933) comb. nov. and P. agdae (Martins, Galileo and Santos-Silva, 2015) comb. nov. All the species are illustrated, and a key to the Bolivian species of Phygopoda and host flower records are provided.
A primitive subfamily of false click beetles (Coleoptera: Eucnemidae: Phlegoninae) distributed primarily in the Neotropical region is revised. Euryphlegon gen. nov. is described from Belize in Central America. New species include: Phlegon chiriquiensis sp. nov. (Panama), Phlegon panamensis sp. nov. (Panama), Euryphlegon jacqueschassaini sp. nov. (Panama) and Euryphlegon parallelus sp. nov. (Belize). Phlegon herculeanus (Lacordaire) stat. res. is resurrected from synonymy with Phlegon buqueti Laporte. One new combination is proposed: Euryphlegon degallieri (Muona) (Phlegon). Based on a number of observed external character traits, Euryphlegon is placed in Orodotini Muona, 1993 within Macraulacinae Fleutiaux, 1922. Identifi cation keys are provided for species of Phlegon and Euryphlegon in the Neotropical region. The relationships among Phlegon, Euryphlegon, Euryptychus LeConte and other groups within Echthrogasterini Cobos, 1964 and Orodotini are discussed.
Abstract. Six new species of Coleoxestia Aurivillius, 1912 (Cerambycidae, Cerambycinae, Cerambycini) are described: C. clarkei from Bolivia; C. chemsaki and C. eyai from Peru; C. fragosoi and C. rafaeli from Brazil; and C. hovorei from Ecuador. Coleoxestia rachelae Eya and Chemsak is also newly recorded from Peru (new country record). Dorsal, ventral and lateral illustrations along with illustrations of various other structures are provided for each of the new species. In some cases, existing key couplets by Eya and Chemsak (2005) or Martins and Monné (2005) are modifi ed to help separate a new species from similar existing species. A reproduction of the general descriptive terminology for the head, prothorax and antennomeres of Coleoxestia, from Fragoso (1993), is also included in the illustrations.
The New World genus Chariessa Forster (Coleoptera: Cleroidea: Cleridae) is revised and includes C. catalina Opitz, new species, C. elegans Horn, C. dichroa (LeConte), C. floridana Schaeffer, C. pilosa (Forster), C. texana Wolcott, C. ramicornis Perty, C. vestita (Chevrolat), and C. duponti (Spinola). Enoplium pilosa var. marginata Say is synonymized with Chariessa pilosa Forster. Lectotypes are designated for C. pilosa (Forster), C. ramicornis Perty, and C. vestita (Chevrolat). Available information indicates that Chariessa adult and immature individuals are predatory on lignicolous insects with a particular affinity for cerambycids and buprestids that infest species of oak. It is postulated that Pleistocene speciation generated the North American components of Chariessa with more ancient southern species generated during the Middle Tertiary; after closures of the Middle American portals and orogeny of the South American Andes. Included in this treatise is a discussion of natural history, key to species, narratives of zoogeography and phylogeny, one diagram of a phylogenetic tree, 35 line drawings, eight SEM micrographs, twelve habitus photographs, nine photographs of male genitalia, and five distributional maps.
A detailed study of the holotype of Sphecomyrma canadensis Wilson, 1985 (Hymenoptera: Formicidae) from Canadian amber has led to the conclusion that the specimen belongs to a new genus, here named Boltonimecia gen.n. Since the taxonomy of stem-group ants is not well understood, in order to find the taxonomic position of this genus, it is necessary to review the classifi cation of stem-group ants in a study of their relation to crown-group ants. In the absence of data for traditional taxonomic approaches, a statistical study was done based on a morphometric analysis of antennae. Scape elongation is believed to play an important role in the evolution of eusociality in ants; however, this hypothesis has never been confirmed statistically. The statistical analysis presented herein lends support to the view that antennal morphology reliably distinguishes stem-group ants from crown-group ants, to determine whether a species belongs to one or the other group. This, in turn, may indicate a relationship exists between eusociality and scape elongation. A review of Cretaceous records of ants is made and the higher classification of Formicidae with definitions of stem and crown groups is proposed. Newly obtained data are discussed focusing particularly on the origin, evolution and diversity of ants.
Dipropus tequesta Johnson new species (Coleoptera: Elateridae) is described from southern Florida. Dipropus fuscus (LeConte) is a new synonym of D. soleatus (Say), and D. granosus (Fall) is a new synonym of D. asper (LeConte). The fl ightless female of D. asper is described and provides the fi rst report of brachyptery and endogean habits in Dipropus. A key to the species of the eastern United States and a new checklist of species for the country are provided.
Una nueva especie del género Eugnosta Hübner, E. lankinae n.sp. (Lepidoptera: Tortricidae), es descrita para la Provincia de Elqui, Chile. Se entregan los caracteres morfológicos del adulto y las fi guras de la genitalia masculina. Además se discute su posición sistemática con dos especies congéneres Neotropicales.
The taxonomic history of the rhinotragine genera Phygopoda Thomson, 1864 and Pseudophygopoda Tavakilian and Peñaherrera-Leiva, 2007 (Coleoptera: Cerambycidae: Cerambycinae) are discussed, and evidence is presented to suggest that some recent taxonomic changes made by Carelli and Monné (2015) were unjustified. Consequently, Phygopoda nigritarsis Gounelle, 1911 is moved to the genus Neophygopoda Melzer, 1933, creating the new combination Neophygopoda nigritarsis, the genera Panamapoda Clarke, 2014 and Paraphygopoda Clarke, 2014 are revalidated, and the species Paraphygopoda viridimicans (Fisher, 1952) and Paraphygopoda nappae Clarke, 2014 are also revalidated.
Chiquitano gen. nov. Chiquitano volcanesensis sp. nov., Compsibidion achiraensis sp. nov. and Compsibidion amboroensis sp. nov. (Coleoptera: Cerambycidae: Cerambycinae: Neoibidionini) are described from Bolivia. Notes on Rhysium Pascoe, 1866 and Rhysium bimaculatum Pascoe, 1866 are provided, and Brechmoidion separatum Martins and Galileo, 2007 is transferred to Rhysium. Keys to species of Compsibidion Thomson, 1864, Brechmoidion Martins, 1969 and Rhysium Pascoe, 1866 are also provided.
We describe a new butterfl y species, Anaeomorpha mirifi ca Simon and Willmott, n. sp. (Lepidoptera, Nymphalidae, Charaxinae), from premontane rain forest of the Chocó region of northwestern Ecuador. This represents the second known species and the fi rst record outside of the Amazon basin for this taxonomically and biologically enigmatic genus. Although the two species are not known to be sympatric, we identifi ed 21 characters in the external color pattern, wing shape and male genitalia that together support distinct species status. Most notably, the new species possesses an ocellus in the ventral hind wing tornus, a character which occurs in the Neotropical Charaxinae only in the genus Prepona Boisduval, 1836. A mean divergence of 6.8% in the COI ‘barcodes’ between the two species underlines their taxonomic distinctness.
