A new genus of jumping spider from the Bolivian Yungas forest, a new country record for Erica eugenia Peckham & Peckham, 1892, and notes on turtle ant mimicry (Araneae: Salticidae: Simonellini)

Arachnology, 2022
A new genus and species of the ant-resembling jumping spider tribe Simonellini, Flurica sikimira gen. et sp. nov., from the Yungas mountain forest in the Bolivian Andes is described.

Predatory Behavior of Jumping Spiders

Annual Review of Entomology, 1996
Salticids, the largest family of spiders, have unique eyes, acute vision, and elaborate vision-mediated predatory behavior, which is more pronounced than in any other spider group. Diverse predatory strategies have evolved, including araneophagy, aggressive mimicry, myrmicophagy, and prey-specific prey-catching behavior. Salticids are also distinctive

Sexual selection on jumping spider color pattern: investigation with a new quantitative approach

, 2021
How animals assess information encoded in individual color patches have been extensively studied, yet the role of both individual color patches and gross color pattern (i.e., the combination of color patches) remains understudied.

Fine structure of the eyes of jumping spiders

Journal of Ultrastructure Research, 1971
The four pairs of eyes in two species of jumping spiders (Metaphidippus harfordi and Phidippus johnsoni) were studied by light and electron microscopy. Unique features of the anteromedial eyes, used in acute vision, are: stratification of receptors (basis of color vision?); rhabdomeres in anterior row of receptors in two planes perpendicular to each ...

Cold tolerance strategy, supercooling, and cold hardening in three populations of the jumping spider Phidippus audax (Araneae: Salticidae)

The journal of arachnology
. Cold temperatures can cause injury and death, and thermal tolerance influences organismal abundance, distribution, and physiology. We characterized cold tolerance and supercooling point (SCP) in the broadly distributed jumping spider Phidippus audax ...

Hypersensitivity in the Anterior Median Eye of A Jumping Spider

Journal of Experimental Biology, 1976
ABSTRACT Changes in sensitivity of the photoreceptor cells of the anterior median eye of the jumping spider Menemerus confusus Boes, et Str. have been studied by recording electroretinograms (ERGs) and receptor potentials. The amplitudes of the responses (ERGs and receptor potentials) increase during repetitive stimulation, with a ...

Phylogenetic relationships and systematics of the jumping spider genus Colopsus with the description of eight new species from Sri Lanka (Araneae: Salticidae)

Journal of Natural History, 2020
The Sri Lankan jumping spider species first described as Colopsus cancellatus and its close relatives are an understudied yet charismatic part of the fauna of the island.

Visual attention and processing in jumping spiders

Trends in Neurosciences
Jumping spiders have extraordinary vision. Using multiple, specialized eyes, these spiders selectively gather and integrate disparate streams of information about motion, color, and spatial detail. The saccadic movements of a forward-facing pair of eyes allow spiders to inspect their surroundings and identify objects.

Individual preference functions exist without overall preference in a tropical jumping spider

Animal Behaviour, 2020
Female mate choice is a widespread and well-recognized phenomenon. Nevertheless, individual variation in female preference has not yet received the same attention, although such preferences can have important effects on evolutionary dynamics.

The Jumping Mechanism of Salticid Spiders

Journal of Experimental Biology, 1959
ABSTRACT Photographs of the jumping spider Sitticus pubescens (Salticidae) show that the jump is almost entirely due to the sudden straightening of the fourth pair of legs. Multiple-image photographs show the importance of a silk drag-line in controlling the jump. The torques at the leg joints have been estimated. Extension torques occur
