Studies on species of Holarctic Pardosa groups (Araneae, Lycosidae). VIII. The Palearctic species of the Pardosa nigra group.
The eight Palearctic species of the Pardosa nigra group are reviewed, illustrated and keyed. Two of them are redescribed: Pardosa lyrata (Odenwall, 1901) and P. paramushirensis (Nakatsudi, 1937). The former is widespread in Siberia and has also been found in Mongolia while the latter has been recorded from Japan (Honshu and Hokkaido) and Russia: the Kuril Islands (a neotype is designated from t...
متن کاملRedescription of three Hippasa species from China (Araneae: Lycosidae), with a proposed species group-division and diagnosis.
The genus Hippasa is a group of web-weaving lycosids, whose web is funnel-like, quite similar to those of the Agelenidae. In this paper, based on published papers and specimens from China, we diagnose and discuss the composition of this genus. Two species groups are recognised, the Hippasa greenalliae-group (12 species and a subspecies) mainly from Asia and the Hippasa partita-group (17 species...
متن کاملThe effects of hunger on locomotory behaviour in two species of wolf spider (Araneae, Lycosidae).
We compared the influence of recent feeding history on locomotory behaviour in two species of wolf spiders, Hogna helluo (Walckenaer) and Pardosa milvina Hentz, in the laboratory. Both species are cursorial hunters. We maintained the spiders in the laboratory on satiation and stringent feeding regimes and measured their locomotory activity levels for 1 h using a digital activity recording devic...
متن کاملSexual Dimorphism in the Metabolic Rate of Two Species of Wolf Spider (araneae, Lycosidae)
Spiders have long been noted as classic examples of extreme sexual dimorphism and adaptations to the lifestyle of a sit-and-wait predator. We examined sex-based differences in the metabolic rate of two species of wolf spider that differ in their degree of sexual dimorphism and predatory strategy. Pardosa milvina (Hentz 1877) is a small active wolf spider that does not exhibit a large degree of ...
متن کاملVisual odometry in the wolf spider Lycosa tarantula (Araneae: Lycosidae).
The wolf spider Lycosa tarantula homes using path integration. The angular component of the displacement is measured using a polarized-light compass associated with the functioning of the anterior median eyes. However, how L. tarantula estimates the linear component of the displacement was not known prior to this investigation. The ability of L. tarantula to gauge the distance walked after bein...
