Lyssomaninae
Lyssomaninae is a subfamily of jumping spiders. It includes four genera, three from the New World. Description Members of the subfamily Lyssomaninae are mostly green or yellow, and have long legs compared to other salticids. The anterior lateral eyes form a second row behind the anterior median eyes. The male palpal bulb has a membraneous conductor. Taxonomy The subfamily Lyssomaninae, as described in 1976 by MarÃa Elena Galiano and in 1980 by Wanless, was agreed by both authors not to be monophyletic, and to consist of three groups. It was formally divided into three subfamilies, Onomastinae, Asemoneinae and Lyssomaninae ''s.s.'', by Wayne Maddison in 2015. He included only two genera, '' Chinoscopus'' and '' Lyssomanes'', although noting that ''Lyssomanes'' might be paraphyletic. Molecular data strongly supported the monophyly of the group defined in this way. In 2016, Maddison described a new genus, ''Sumakuru'', which he placed in Lyssomaninae. Maddison originally kept t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asemoneinae
Asemoneinae is a subfamily of jumping spiders (family Salticidae). It was created in 2015 by Wayne Maddison. Most species are found in Africa or Asia. The subfamily initially had five genera, but '' Hindumanes'' was later transferred to the subfamily Lyssomaninae. Description Members of the subfamily Asemoneinae are translucent and long-legged relative to most other salticids. They resemble members of the subfamilies Onomastinae and Lyssomaninae ''sensu'' Madison, 2015. The posterior median eyes are unusually central for salticids, being distinctly closer to the midline than is the inner edge of the anterior lateral eyes. Taxonomy In 2015, Wayne Maddison divided the subfamily Lyssomaninae, as circumscribed in 1980 by Wanless, into three subfamilies, Onomastinae, Asemoneinae and Lyssomaninae ''s.s.'' Maddison included five genera. Molecular data united the three sampled genera, '' Asemonea'', ''Goleba'' and '' Pandisus''. Two genera, '' Hindumanes'' and ''Macopaeus'', were ...

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 ...

Lyssomanes
''Lyssomanes'' is a spider genus of the family Salticidae (jumping spiders), ranging from South and Central America, up to the southern United States. There have been described 94 extant and two fossil species from the Neotropical Region. The genera ''Lyssomanes'', '' Chinoscopus'', '' Hindumanes'', and ''Sumakuru'' make up the Lyssomaninae, which is one of the six deeply-diverging subfamilies of jumping spiders. They are long-legged, with translucent bodies frequently green or yellow. They resemble lynx spiders, except that they have large anterior median eyes. Habitat ''Lyssomanes'' are typically found in foliage in mesic habitats. Species , the World Spider Catalog accepted the following species: *''Lyssomanes adisi'' Logunov, 2002 – Brazil *''Lyssomanes amazonicus'' Peckham, Peckham & Wheeler, 1889 – Colombia, Ecuador, Bolivia, Brazil, Guyana *''Lyssomanes anchicaya'' Galiano, 1984 – Costa Rica, Panama, Colombia *''Lyssomanes antillanus'' Peckham, Peckham & Whee ...

Onomastinae
''Onomastus'' is a genus of Asian jumping spiders (family Salticidae) that was first described by Eugène Louis Simon in 1900. It is the only genus in the subfamily Onomastinae. Description ''Onomastus'' species are delicate, translucent spiders, with long legs compared to most other members of the family Salticidae. Males have highly complex palpal bulbs. Two clades have been distinguished: in species from Southeast Asia, the palpal bulb has a broad conductor; in those from South Asia it has a medial branch on the median apophysis. Like species of the subfamilies Lyssomaninae and Asemoneinae, the anterior lateral eyes form a separate row from the anterior median eyes. The genus was originally diagnosed on the basis of the arrangement of the eyes. Taxonomy The genus ''Onomastus'' was first described by Eugène Simon in 1900. He placed it in the "Attidae", the name he then used for the family Salticidae. It was later placed in a broadly defined subfamily Lyssomaninae, althou ...

Palpal Bulb
The two palpal bulbs – also known as palpal organs and genital bulbs – are the copulatory organs of a male spider. They are borne on the last segment of the pedipalps (the front "limbs" of a spider), giving the spider an appearance often described as like wearing boxing gloves. The palpal bulb does not actually produce sperm, being used only to transfer it to the female. Palpal bulbs are only fully developed in adult male spiders and are not completely visible until after the final moult. In the majority of species of spider, the bulbs have complex shapes and are important in identification. Structure The palpal bulb of a mature male spider is borne on the last segment of the pedipalp. This segment usually has touch-sensitive hairs (setae) with nerves leading to them. The bulb itself is entirely without nerves, and hence without sensory organs and muscles, since these depend on nerves for their functioning, although some spiders have one or two muscles external to the bulb and ...

MarÃa Elena Galiano
MarÃa Elena Galiano (1928 – October 30, 2000) was an Argentine arachnologist. She was one of the leading taxonomists of Neotropical jumping spiders. Galiano worked at the Bernardino Rivadavia Natural Sciences Museum in Buenos Aires. She died in an accident on October 30, 2000. The genera ''Galianora'' and ''Galianoella'' are named in her honor. Taxa described Galiano described numerous species and genera of spiders. She is the authority for the following genera: * '' Admesturius'' Galiano, 1988 * '' Hisukattus'' Galiano, 1987 * '' Kalcerrytus'' Galiano, 2000 * '' Nycerella'' Galiano, 1982 * '' Simonurius'' Galiano, 1988 * '' Sumampattus'' Galiano, 1983 * '' Trydarssus'' Galiano, 1995 * '' Wedoquella'' Galiano, 1984 * ''Yepoella ''Yepoella'' is a monotypic taxon, monotypic genus of Argentinian Salticidae, jumping spiders containing the single species, ''Yepoella crassistyli''.

Monophyly
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 taken ...

Genera
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 ...
