A New Species And Significant Range Extension For The Genus Fractipes Bechynĕ (Coleoptera: Chrysomelidae: Eumolpinae: Eumolpini), Wills Flowers

Insecta Mundi

Fractipes tayrona new species (Coleoptera: Chrysomelidae: Eumolpinae: Eumolpini) is described from a dry forest on the Caribbean coast of Colombia. This locality is very distant from the localities in southeast Brazil, where the other two known species of Fractipes Bechynĕ were described. Male and female genitalia are described for the first time in this genus, and F. tayrona is compared with holotype photographs of F. rhabdopteroides Bechynĕ and F. secundus Bechynĕ and Springlová de Bechynĕ.

Three New Species Of South American Checkered Beetles (Coleoptera: Cleridae: Clerinae), Weston Opitz

Insecta Mundi

Three new species of Enoclerus Gahan (Coleoptera: Cleridae) are described and illustrated. They are: Enoclerus minas Opitz from Colombia and Brazil, E. salta Opitz from Argentina, and E. thomasi Opitz from Bolivia.

Corporaal (1950: 14) lists 185 species of Enoclerus Gahan (Coleoptera: Cleridae: Clerinae). I know of over 60 undescribed species. It is a daunting task to organize such a high number of species into some sort of taxonomic revision, which cannot be provided at this time. However, some of these new species can be described that will be added to a larger work at a later date. Such descriptive …

Drivers Of Ant Composition, Richness, And Trophic Guilds In Neotropical Iron Ore Cavities, Rodrigo A. Castro-Souza, Thais G. Pellegrini, Marconi Souza-Silva, Rodrigo L. Ferreira

International Journal of Speleology

Subterranean habitats may be considered limiting for animal colonization, especially for ants, due to permanent darkness and mainly because of oligotrophic conditions. While not as deep as limestone caves, iron ore caves and other subterranean habitats may be more available for colonization because of their shallower depth. We use the richness and composition of ants to assess how differences in habitat structure affect the biodiversity and ecosystem function between cavities and surrounding epigean landscapes. We predicted that the distribution of ants would be different because of the variation in habitat structure and cavity conditions may act as a filter for …

A Fourth Account Of Centipede (Chilopoda) Predation On Bats, T. Todd Lindley, Jesús Molinari, Rowland M. Shelley, Barry N. Steger

Insecta Mundi

With an incident in Palo Duro Canyon, Texas, USA, Scolopendra heros Girard (Chilopoda: Scolopendromorpha: Scolopendridae) becomes the third centipede species known to prey on bats; S. gigantea Linnaeus and S. viridicornis Newport have been so documented in Venezuela and Brazil, respectively. The Texas predation was interrupted by the predator/prey pair’s falling around 15–20 m from the canyon wall and, perhaps also, by human presence where they landed. The centipede uncoiled and retreated to shelter under a nearby rock and, after initial immobilization, so did the bat.

Corrections To Neotropical Rhinaspis Perty And Plectris Lepeletier And Audinet-Serville (Coleoptera: Scarabaeidae: Melolonthinae) Classifi Cation And Nomenclature, Andrew B. T. Smith

Insecta Mundi

The name Melolontha hypocrita Mannerheim, 1829 has been long unused, even though it is the type species of Hyporhiza Dejean, 1833. I examined the only known specimen from the type series and here designate it as the lectotype. Examination of this lectotype reveals that this species is best placed in the genus Rhinaspis Perty, 1830. Consequently, the genus Hyporhiza Dejean, 1833 is confi rmed as a junior synonym of Rhinaspis. Further, the replacement name Rhinaspis fuhrmanni is proposed for Rhinaspis hypocrita (Blanchard, 1850), a new secondary homonym of Rhinaspis hypocrita (Mannerheim, 1829). A homonymy problem was also discovered and …

Convergent Habitat Segregation Of Aedes Aegypti And Aedes Albopictus (Diptera : Culicidae) In Southeastern Brazil And Florida, Marieta A H Braks, Ricardo Lourenco-De-Oliveira, Steven A. Juliano, Nildimar A. Honorio, L Philip Lounibos

Faculty Publications – Biological Sciences

During the rainy season of 2001, the incidence of the dengue vectors Aedes aegypti and Ae. albopictus was examined in different habitats of two cities (Rio de Janeiro and Nova Iguacu) in Rio de Janeiro State, Brazil, and in two cities (Palm Beach and Boca Raton) in Florida. Oviposition trap collections were performed in urban, suburban, and rural habitats in both areas. Our hypothesis that the abundances and frequencies of occurrence of Ae. aegypti and Ae albopictus are affected in opposite ways by increasing urbanization was only partially supported. City, habitat, and their interaction significantly affected the abundance of both …
