Laufeia Sicus
''Laufeia'' is a spider genus of the jumping spider family, Salticidae, with a mainly Asian distribution, where they are found on tree trunks and branches or among leaf litter. Description ''Laufeia'' species are mostly small, hairy, brownish spiders. The chelicerae, chelicera usually has a tooth with two cusps on the rear-facing edge. The male generally has a slightly hardened plate (Scute, scutum) on the upper surface of the abdomen. The genitalia vary considerably between species; for example, the male palpal bulb has either a long or short embolus, which may or may not be coiled. Taxonomy The genus ''Laufeia'' was erected by Eugène Simon in 1889 for the type species ''Laufeia aenea'', which had been collected in Yokohama, Japan. Simon did not explain the origin of the genus name. In Norse mythology, Laufeia was the mother of the god Loki. Four more ''Laufeia'' species were known to Andrzej Bohdanowicz and Jerzy Prószyński in 1987; they doubted that three of them belonged ...

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene fossil spider species '' Cenotextricella simoni'' was named in h ...

Wayne Maddison
Wayne Paul Maddison , is a professor and Canada Research Chair at the departments of zoology and botany at the University of British Columbia, and the Director of the Spencer Entomological Collection at the Beaty Biodiversity Museum. His research concerns the phylogeny, biodiversity, and evolution of jumping spiders (Salticidae), of which he has discovered new species and genera. He has also done research in phylogenetic theory, developing and perfecting various methods used in comparative biology, such as character state inference in internal nodes through maximum parsimony, squared-change parsimony, or character correlation through the concentrated changes test or pairwise comparisons. In collaboration with David R. Maddison, he worked on thMesquiteopen-source Open source is source code that is made freely available for possible modification and redistribution.
