Thiratoscirtus Harpago
''Thiratoscirtus harpago'' is a species of jumping spider in the genus ''Thiratoscirtus'' that lives in Nigeria. The species was first described in 2011 by Wanda Wesołowska and Russell-Smith. Only the male has been identified. It is a medium-sized spider, with a cephalothorax that is typically 3.9 mm long and an abdomen that is 2.7 mm in length, both oval in shape. The carapace is generally dark brown and the abdomen dark greyish-fawn on top. The clypeus, or face, has a triangular marking of white hairs. The mouthparts include large chelicerae and a short fang. Its copulatory organs are unusual, including the a very small palpal bulb enclosed in a cymbium that is shaped like a half-moon and a hook at the end of the embolus, which is recalled in the species name, a Latin word that can be translated "harpoon".

Wanda Wesołowska
Wanda Wesołowska (born 11 August 1950) is a Polish zoologist known for her work with jumping spiders. She has described more species of jumping spider than any contemporary writer, and is second only to Eugène Simon in the history of arachnology. Originally a student of ornithology, she developed an interest in jumping spiders while still a student at the Siedlce University of Natural Sciences and Humanities in the 1970s. She subsequently undertook study into the genus ''Heliophanus'' at the University of Wroclaw. Her subsequent doctoral thesis described 44 new species, and joined the staff at the university. She stayed until retiring in 2020. Her research included the taxonomy and zoogeography of jumping spiders, and has included extensive work on African genera like ''Menemerus'' and ''Pachyballus''. She has identified over 500 species, including half of all those from South Africa, as well as having more than 20 named after her. Early life Wanda Wesołowska (née Nowysz) was ...

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 ...

Clade (biology)
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organis ...

Subclade
In genetics, a subclade is a subgroup of a haplogroup. Naming convention Although human mitochondrial DNA (mtDNA) and Y chromosome DNA (Y-DNA) haplogroups and subclades are named in a similar manner, their names belong to completely separate systems. mtDNA mtDNA haplogroups are defined by the presence of a series of single-nucleotide polymorphism (SNP) markers in the hypervariable regions and the coding region of mitochondrial DNA. They are named with the capital letters A through Z, with further subclades named using numbers and lower case letters. Y-DNA Y-DNA haplogroups are defined by the presence of a series of SNP markers on the Y chromosome. Subclades are defined by a ''terminal SNP'', the SNP furthest down in the Y chromosome phylogenetic tree. Human Y-DNA The Y Chromosome Consortium (YCC) developed a system of naming major human Y-DNA haplogroups with the capital letters A through T, with further subclades named using numbers and lower case letters (YCC longhand nomenc ...

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 (phylogenetics), 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 phylogeny software, thMacCladeprogram, and the Tree of Life Web Project. His research has led him to discover new species of jumping spiders in Sarawak and Papua New Guinea. Selected pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alfenus
''Alfenus'' is a genus of jumping spiders. The two species were described by Eugène Simon in the early 1900s, based on a single male specimen each. However, the two species are so different that they probably do not belong to the same genus (Szűts & Scharff, 2005). ''Alfenus calamistratus'' has a characteristic hairy appearance. The males (no females have been observed yet) are 7 (''A. chrysophaeus'') to 9 millimeters (''A. calamistratum'') long, with a dark brown carapace. The hairs on ''A. calamistratum'' are white or brownish-orange. Species * '' Alfenus calamistratus'' Simon, 1902 – Congo basin * '' Alfenus chrysophaeus'' Simon, 1903 – Equatorial Guinea Equatorial Guinea ( es, Guinea Ecuatorial; french: Guinée équatoriale; pt, Guiné Equatorial), officially the Republic of Equatorial Guinea ( es, link=no, República de Guinea Ecuatorial, french: link=no, République de Guinée équatoria ... or Cameroon References * Szűts, T. & Scharff, N.

Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy.
