Hisponinae
Hisponinae is a subfamily of jumping spiders (family Salticidae). The subfamily has six known extant genera and three extinct genera. Description Members of the subfamily Hisponinae have a distinctive constriction or furrow in the carapace just behind the small eyes. They share some features with those of the much larger subfamily Salticinae, such as reduction of the size of the posterior median eyes, and the loss of the conductor of the palpal bulb. Hisponine females have a very much reduced tarsal claw on the pedipalp (salticines have lost this claw altogether). Taxonomy The group was first described by Eugène Simon in 1901 as "Hisponeae". It has subsequently been treated as the subfamily Hisponinae, often using the informal name "hisponines". Phylogeny The relationships among the basal salticids are not yet fully resolved; summary cladograms published in both 2014 and 2015 show unresolved branching for five basal subfamilies. However, Hisponinae is resolved as sister to Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salticinae
Salticinae is a subfamily of jumping spiders (family Salticidae). It includes over 90% of the known species of jumping spiders. The subfamily is divided into two unranked clades: Amycoida and Salticoida. Description Members of the subfamily Salticinae have a number of features in common that distinguish them from the remaining salticids. Females lack a tarsal claw on the pedipalp. The palpal bulb of male basal salticids has a distinctive median apophysis, which is absent in the subfamily, and the cymbium is constricted at the tibial joint. Members also have a more complex tracheal system, which may be connected with their movements, which are more abrupt than other salticids, giving them a recognizable gait. Taxonomy Phylogeny The relationships among the basal salticids are not yet fully resolved; summary cladograms published in both 2014 and 2015 show unresolved branching for five basal subfamilies. However, Hisponinae is resolved as sister to Salticinae, which is the mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jumping Spider
Jumping spiders are a group of spiders that constitute the family (biology), family Salticidae. As of 2019, this family contained over 600 described genera and over 6,000 described species, making it the largest family of spiders at 13% of all species. Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and Invertebrate trachea, tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the Anatomical terms of location, anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baltic Amber
The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014, 400 tonnes in 2015. "Baltic amber" was formerly thought to include amber from the Bitterfeld Lignite, brown coal mines in Saxony (Eastern Germany). Bitterfeld amber was previously believed to be only 20–22 million years old (Miocene), but a comparison of the animal inclusions in 2003 suggested that it was possibly Baltic amber that was redeposited in a Miocene deposit. Further study of insect taxa in the ambers has shown Bitterfeld amber to be from the same forest as the Baltic amber forest, but separately deposited f ...

Alexander Petrunkevitch
Alexander Ivanovitch Petrunkevitch (Russian: Александр Иванович Петрункевич, December 22, 1875 in Plysky near Kyiv, now Ukraine – March 9, 1964 in New Haven) was an eminent Russian arachnologist of his time. From 1910 to 1939 he described over 130 spider species. One of his most famous essays was "The Spider and the Wasp." In it he uses effective word choices and some comic touch. Biography His aristocratic father, Ivan Illitch Petrunkevitch, was a liberal member of the First Duma and founded the Constitutional Democratic Party. After finishing his studies in Moscow and in Freiburg under August Weismann, Alexander settled in Yale in 1910, becoming a full professor in 1917. Apart from describing present-day species, he was a major figure in the study of fossil arachnids, including those in amber and from the Coal Measures. He also experimented with live specimens and worked on insects. Professor Petrunkevitch's formulation of the principle of p ...
