Marchena
''Marchena'' is a genus of jumping spiders only found in the United States. Its only described species, ''M. minuta'', dwells on the barks of conifers along the west coast, especially California, Washington and Nevada.Maddison, Wayne. 1995. Marchena. Marchena minuta. Version 1 January 1995 (under construction). http://tolweb.org/Marchena_minuta/2986/1995.01.01 in The Tree of Life Web Project, http://tolweb.org/ It forms a monophyletic group with the genera ''Afraflacilla'', ''Pseudicius'' and '' Festucula''.Zabka & Grey 2002 Description This species can easily be distinguished from others in its range by the tubercles on the first femur of its first legs. ''M. minuta'' has a body length of about 4 mm. Name The genus name is probably derived from the Spanish city of Marchena, Seville. As witnessed by other generic names, the describers had a habit of naming taxa after places unrelated to the species' distribution. The species name is Latin Latin (, or , ) is a c ...

Afraflacilla
''Afraflacilla'' is a genus of the spider family Salticidae (jumping spiders). Most species are distributed in Eastern to Northern Africa (including the Middle East) and Australia, with two species (''A. epiblemoides and A. tarajalis'') found in Europe. This genus was for a time included in the genus ''Pseudicius'', and the boundaries between both genera are disputed. In 2016 Jerzy Prószyński erected the genus ''Psenuc'' for some borderline species. The name ''Afraflacilla'' is combined from Africa, where most earlier described species were found, and ''Flacilla'' Simon, 1901, an obsolete salticid genus now called '' Flacillula'' Strand, 1932. This genus name is in turn derived from Aelia Flaccilla, wife of Roman Emperor Theodosius I. ''Afraflacilla'', ''Pseudicius'', '' Festucula'' and ''Marchena'' are close relatives and form a monophyletic group. Afraflacilla species have tubercles and bristles (on the sides of the carapace near the eyes and on their legs) which they r ...

Pseudicius
''Pseudicius'' is a genus of the jumping spiders first described by Eugène Simon in 1885. The name is combined of Greek ''pseudo'' "false" and the salticid genus name ''Icius''. The small genus '' Wesolowskana'' (formerly known as ''Luxuria'') should possibly be included in this genus. There is some dispute whether ''Afraflacilla'' is a distinct genus or should be included in ''Pseudicius''. '' Festucula'' and ''Marchena'' are other close relatives, these genera form a monophyletic group. Species , the World Spider Catalog accepted the following species. Many species formerly placed here have been transferred to a variety of other genera. * '' Pseudicius adustus'' Wesołowska, 2006 – Namibia * '' Pseudicius africanus'' Peckham & Peckham, 1903 – South Africa, Lesotho * '' Pseudicius amicus'' Prószyński, 2000 – Middle East * '' Pseudicius andamanius'' ( Tikader, 1977) – Andaman Islands * '' Pseudicius athleta'' Wesołowska, 2011 – Uganda, Kenya * '' Pseudicius badius ...

George And Elizabeth Peckham
George Williams Peckham (March 23, 1845 – January 10, 1914) and Elizabeth Maria Gifford Peckham (December 19, 1854 – February 11, 1940) were a married couple who were early American teachers, taxonomists, ethologists, arachnologists, and entomologists, specializing in animal behavior and in the study of jumping spiders (family Salticidae) and wasps. Lives and careers George Peckham was born in Albany, New York in 1845. At age 18, he enlisted in the U.S. Army to fight in the American Civil War, reaching the rank of first lieutenant. After the war, he resumed his studies, obtaining a law degree from Albany Law School in 1867. After graduation, George worked at the law office of James T. Brown of Milwaukee. Not caring for the law, however, he became a student in the medical college of the University of Michigan, earning his M.D. in 1872. Rather than practice medicine, however, he chose to teach biology at East Division High School of Milwaukee, Wisconsin. In 1 ...

Genus (biology)
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

Salticidae
Jumping spiders are a group of spiders that constitute the 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 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 anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider families because of the shape of the cephalothorax and their eye pa ...

Conifer
Conifers are a group of conifer cone, cone-bearing Spermatophyte, seed plants, a subset of gymnosperms. Scientifically, they make up the phylum, division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class (biology), class, Pinopsida. All Neontology, extant conifers are perennial plant, perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include Cedrus, cedars, Pseudotsuga, Douglas-firs, Cupressaceae, cypresses, firs, junipers, Agathis, kauri, larches, pines, Tsuga, hemlocks, Sequoioideae, redwoods, spruces, and Taxaceae, yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecology, ecologically important. They are the dominant plants over large areas of land, most ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...
