Afraflacilla Arabica
''Afraflacilla arabica'' is a species of jumping spider in the genus '' Afraflacilla'' that lives in Afghanistan, Iran and Yemen. The spider was first described in 1994 by Wanda Wesołowska and Antonius van Harten. The spider is small to medium-sized, with an elongated brown carapace that is between 1.7 and 1.85 long and an oval greyish-brown abdomen between 2.25 and 3.0 mm long. The female and male are similar externally, differing mainly in the male's larger and thicker brown front legs that mount stridulatory apparatus. The remainder of the legs are smaller and yellow. The female is also slightly lighter. The spiders have distinctive copulatory organs. The male has a long embolus extending around the palpal bulb. The female has wide insemination ducts, small spermathecae and large accessory glands. Taxonomy ''Afraflacilla arabica'' is a jumping spider that was first described by Wanda Wesołowska and Antonius van Harten in 1994. It is one of over 500 species identified by ...

Marek Michał Żabka
Marek Michał Żabka (born 1955) is a Polish arachnologist. His main research area is the spider family Salticidae (jumping spiders), especially their systematics and biogeography. He has produced nearly 80 scientific publications, popular science articles and a book. The World Spider Catalog lists 25 genus names or synonyms and 237 species names or synonyms of which he is either the sole author or a co-author. Nine jumping spider species and one ant spider species have been given the specific name ''zabkai''. He received a master's degree in biology in 1978 from the Higher School of Agriculture and Pedagogy (Wyższa Szkoła Rolniczo-Pedagogiczna) in Siedlce – now the Siedlce University of Natural Sciences and Humanities. He then worked there, first as an assistant and then as adjunct professor. In 1984, he was awarded a PhD in biological sciences by the Department of Earth Sciences and Biology at the Adam Mickiewicz University in Poznań under the supervision of Jerzy Prósz ...

Spider Vision
The eyes of spiders vary significantly in their structure, arrangement, and function. They usually have eight, each being a simple eye with a single lens (optics), lens rather than multiple units as in the compound eyes of insects. The specific arrangement and structure of the eyes is one of the features used in the identification and classification of different species, genera, and families. Most Haplogynae, haplogynes have six eyes, although some have eight (Plectreuridae), four (e.g., ''Tetrablemma'') or even two (most Caponiidae). In some cave species, there are no eyes at all (e.g. Stalita taenaria). Sometimes one pair of eyes is better developed than the rest. Several families of hunting spiders, such as jumping spiders and wolf spiders, have fair to excellent vision. The main pair of eyes in jumping spiders even sees in colour. Structure and anatomy Spiders' eyes are Simple eye in invertebrates, simple eyes, or ''ocelli'' (singular ''ocellus''), meaning their eyes have a si ...

Pseudicius Asoroticus
''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'' (Simo ...

Salticoida
Salticoida is an unranked clade of the jumping spider family Salticidae. It is the larger and more widespread of the two subdivisions of the "typical" jumping spiders (subfamily Salticinae), occurring effectively world-wide. Its sister clade is Amycoida, which is also very diverse ecologically but has a mostly South American distribution. Systematics and evolution Salticoida includes the bulk of extant jumping spider diversity, with over 400 genera organized phylogenetically into 18 tribes according to Wayne Maddison's 2015 proposal. The age and origin of the Salticoida are not well determined. Certainly, by the late Paleogene the major lineages were recognizably distinct as indicated by the fossil evidence and molecular phylogeny. Thus, the salticoids presumably originated during or around the PETM or a bit earlier, but no corresponding fossils have been found yet. Their sister lineage, the Amycoida, probably originated by dispersal across the ocean to South America, which ... [...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".

Clade
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 org ...

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 take ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family (biology), family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Goat-antelope#Tribe Caprini, Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Scilloideae#Hyacintheae, Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form ...

Pseudicius Braunsi
''Afraflacilla braunsi'' is a species of jumping spider in the genus ''Afraflacilla''. First found in South Africa, the spider was subsequently observed living in Saudi Arabia, Turkmenistan, the United Arab Emirates and Yemen, although it is likely to have a wider distribution. First described in 1903 by George and Elizabeth Peckham, it was originally allocated to the genus ''Pseudicius'' with the name ''Pseudicius braunsii''. After being renamed ''Icius braunsi'' in 1987, it was finally given its current name by Jerzy Prószyński in 2017. ''Pseudicius tripunctatus'', now called ''Afraflacilla tripunctatus'', is a synonym. A small to medium-sized spider, ''Afraflacilla braunsi'' has a carapace that is between long and an abdomen long. The carapace is brown, sometimes with yellow sides. The abdomen is light brown or fawn with lighter yellow patches. It has large brown front legs, the remainder generally yellow and less robust. It makes noises by rubbing its forelegs against s ...
