  The neonicotinoid imidacloprid impairs the predatory performance and functional response of the jumping spider Helpis minitabunda (Araneae, Salticidae) Abstract The neonicotinoid imidacloprid can cause lethal and sublethal effects in non-target organisms, including impaired behavior, reduced fertility, disrupted locomotion, and reduced predatory performance in arthropods. Spiders are among the most abundant arthropod predators in terrestrial ecosystems, including agricultural ecosystems, yet the effects of neonicotinoids on the predatory function of jumping spiders remain poorly understood. The functional response of a predator describes how predation rates change with prey density and is key to understanding predator–prey dynamics. We tested whether acute exposure to a commercial formulation of imidacloprid at field-recommended concentrations alters the functional response of the Aussie bronze jumping spider, Helpis minitabunda (L. Koch, 1880). We compared the predation of treat...

Abstract

Artoria Thorell, 1877 is revised for the Northern Territory and Queensland. Three species are recorded from the Northern Territory: A. parvula Thorell, 1877 (♂♀, type species), A. superelliptica sp. (♀) and A. vectis sp. Nov. (♂♀). Twenty-seven species (including 18 new ones) are recorded from Queensland: A. albopilata (Urquhart, 1893) (♂♀), A. berenice (L. Koch, 1877) (♂♀), A. bicornuta sp. nov. (♂), A. catinata sp. nov. (♂♀), A. coclearia sp. nov. (♂♀), A. cunicularia sp. nov. (♂♀), A. geniculata sp. ( ♂♀), A. globula sp. nov. (♂♀), A. grahammilledgei Framenau & Baehr, 2018 (♂♀), A . halterata sp. nov. (♀), A. hamifera sp. ( ♂♀), A. laciniata sp. nov. (♀), A. lineata (L. Koch, 1877) (♂♀), A. lingulata sp. nov. (♂♀), A. mckayi Framenau, 2002 (♂♀), A. nasuta sp. nov. (♂), A. orcina sp. nov. (♂♀), A. proboscidea sp. nov. (♂♀), A. quadrata Framenau, 2002 (♂♀), A. reniformis sp. nov. (♀), A. scapulata sp. nov. (♀), A. semicircularis sp. nov. (♂), A. terania Framenau & Baehr, 2018 (♂♀), A. triangularis Framenau, 2002 (♂♀), A. velata sp. nov. (♂), A. victoriansis Framenau, Gotch & Austin, 2006 (♂♀) and A. werrikimbe sp. Nov. (♂♀). This study also added 13 new species of Artoria to New South Wales, seven of these species endemic to the state— A. abscondita sp. nov. (♀), A. ancorata sp. nov. (♀), A. cucurbita sp. nov. (♀), A. limitata sp. nov. (♀), A. longinqua sp. nov. (♀), A. serpentidens sp. (♂♀), and A. tenuis sp. nov. (♀), and one also occurring in the Australian Capital Territory— A. pedroi sp. nov.(♂♀). Summing up, 39 species are taxonomically treated in this paper, including 28 new ones. In addition, we propose the beaury and lingulata species-groups, and redefine the lineata species-group based on male and female genital characteristics.
