THE FAMILY GALLIENIELLIDAE (ARANEAE, GNAPHOSOIDEA) IN THE AMERICAS [PDF]
Abstract Azilia leucostigma Mello-Leitao 1941 considered by Mello-Leitao as a metine (Tetragnathidae), is transferred to the gnaphosoid family Gallieniellidae, as the type species of the new genus Galianoella. The obliquely depressed endites, the flattened irregular posterior median eyes, and the conical anterior lateral spinnerets retaining a ...

Minimising insect mortality during grassland mowing: The potential of insect chasing devices
Insect chasing devices have a great potential to deter arthropods prior to mowing, thereby reducing mortality. The effectiveness of mechanical flushing bars is limited and depends on driving speed, vegetation structure and species composition. The blowing device is the most independent of external factors and therefore the most effective.

Zodarion morosum and Lessertinella kulczynskii are recorded for the first time in Romanian fauna. The species Palliduphantes milleri is reconfirmed. The new illustrations contribute to a better knowledge regarding morphological characterization of the species. The currently known distribution of this species in Romania is also given.

ABSTRACT Spiders are dominant predators in terrestrial ecosystems, regulating invertebrate biomass, diversity and abundance through predation. However, analysing predation patterns in the field is challenging, especially as spiders are extra‐intestinal liquid feeders and often active at night.

Effect of laboratory heat stress on mortality and web mass of the common house spider, Parasteatoda tepidariorum (Koch 1841) (Araneae: Theridiidae) [PDF]
We determined the effects of chronic heat stress on web construction of Parasteatoda tepidariorum (Araneae: Theridiidae) by measuring the survival and web mass of specimens after a 48-h period within a temperature chamber at 21, 30, 35, 40, or 50°C.

The negative impacts of using insecticide‐treated methods and slot traps against Ips cembrae were evaluated. Negative impacts on predator species of bark beetles such as Thanasimus formicarius and Red‐Listed species were described. Abstract BACKGROUND Ips cembrae is serious forest pest of European larch (Larix decidua).

The first record of Oecobius nadiae (Spassky, 1936) (Aranei: Oecobiidae) in Russia [PDF]
Oecobius nadiae (Spassky, 1936) is registered on the territory of Russia for the first time. A single male was found indoors in Makhachkala (Dagestan). This male is slightly larger in size than type specimens.

Assessing spider diversity remains a great challenge, especially in tropical habitats where dozens of species can locally co-occur. Pitfall trapping is one of the most widely used techniques to collect spiders, but it suffers from several biases, and its
