  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...

Description of two new huntsman spiders from Vietnam (Araneae, Sparassidae)

Abstract

Two new species of the sparassid genera Heteropoda Latreille, 1804 and Pseudopoda Jäger, 2000 are described from Vietnam: Heteropoda taygiangensis sp. nov. (♂) from Quang Nam Province and Pseudopoda tadungensis sp. nov. (♀) from Dak Nong Province. The new Pseudopoda species is described and diagnosed based on both morphological characteristics and DNA barcoding. DNA barcode data (COI) are provided for both new species.
