Three new species of Goera Stephens (Trichoptera: Goeridae) from Sulawesi, Indonesia
Three new species of the caddisfly genus Goera Stephens (Trichoptera: Goeridae) are described from
the Indonesian island of Sulawesi. Goera neboissi sp. n., G. jolanda sp. n., and G. higleri sp. n. were found to be related
to G. skiasma Neboiss, which is the only previously recorded species from Sulawesi. These species share the
following combination of characters: an upright IXth segment; the absence of the median dorsal process of tergum X;
a long, mesal process of the inferior appendage with a subbasal projection; and, the absence of parameres
Interesting species of the genus Helicopsyche von Siebold (Trichoptera: Helicopsychidae) from Vietnam
Three new species of the genus Helicopsyche von Siebold (Trichoptera: Helicopsychidae), H. botosaneanui, H. verrucaspinosa, and H. inusitata, from Vietnam are described, and 1 new country record, H. pathoumthongi Johanson and Malm, is reported. The male of H. boniata Malicky and Chantaramongkol is redescribed to facilitate comparisons with two of the new species
The genus Psilotreta Banks (Trichoptera: Odontoceridae) in Vietnam
Eight species of the genus Psilotreta Banks (Trichoptera: Odontoceridae) are currently known from Vietnam: P. albogera Mey 1997, P. androconiata Mey 1997, P. bidens Mey 1995, P. enikoae Oláh and Johanson 2010, P. frigidaria Mey 1996, P. jaroschi Malicky 1995, P. papaceki Malicky 1995, P. spitzeri Malicky 1995. A new species, Psilotreta kurenschikovorum, from Thua Thien-Hue Province is herein described. The new species differs from other species of the genus by peculiarities in wing venation, by the unusual shape of epicranial suture on the head, and by the bifid apical segment of the inferior appendage. Additional province and collection information for previously recorded species are included
Two new species of the genus Pahamunaya Schmid (Trichoptera: Polycentropodidae) from Vietnam
Two new species of the genus Pahamunaya Schmid (Trichoptera: Polycentropodidae), P. talon sp. n. and P. spinifera sp. n., from Vietnam are described and illustrated. Examination of the holotype male of P. khoii Oláh and Johanson, in combination with an additional specimen of the same species, revealed new characters. New illustrations for this species are provided
Additions to the genus Goera Stephens (Trichoptera, Goeridae) from Southeast Asia
Two new species of Goera, G. zwicki and G. nozakii (Trichoptera, Goeridae), from the Philippines and one new species, G. meyi, from Vietnam are described and illustrated herein. In addition, type specimens of G. disparilis Banks, G. octospina Banks, G. tagalica Banks, and G. uniformis Banks are illustrated. All species of Goera known from both the Philippines and Vietnam are listed
In the cities of the beyond: an interview with Paul Virilio
At the request of Open, the cultural theoretician John Armitage interviewed the French urbanist and philosopher Paul Virilio (b. 1932, Paris). A discussion on the future of the city
Crime Prevention through Environmental Design
This chapter is concerned with the extent to which the individual design features of
the built environment (such as a house, school, shopping mall or hospital), as well as
the natural environment surrounding those buildings, impact upon crime risk, and
subsequently, how these features can be altered to reduce that level of risk. This
approach is known as Crime Prevention through Environmental Design (CPTED).
CPTED draws upon opportunity theories that assert that those involved in, or
considering, criminality are influenced (to some extent) by their immediate
environmen
The potential of RIVPACS for predicting the effects of environmental change
RIVPACS has been used successfully for biological assessment of river water quality but its potential in forecasting the effects of environmental change has not been investigated. This study has shown that it is possible to simulate faunal changes in response to environmental disturbance, provided that the disturbance directly involves the environmental variables used in RIVPACS predictions. These variables relate to channel shape, discharge and substratum. Many impacts, particularly those associated with pollution, will not affect these variables and therefore RIVPACS cannot simulate the effects of pollution. RIVPACS was sensitive only to major changes in substratum. It was concluded that, because of the static nature of RIVPACS, it cannot respond to the dynamic effects and processes associated with environmental disturbance. Thus RIVPACS, while showing direction of change and indicating sensitive taxa, cannot be used to predict or forecast the effects of environmental impacts
