Stenaelurillus Pilosus
''Stenaelurillus pilosus'' is a species of jumping spider in the genus ''Stenaelurillus'' that is endemic to Nigeria. It was first described in 2011 by Wanda Wesołowska and Anthony Russell-Smith. The spider is medium-sized, with a brown carapace between in length and an abdomen between in length. It can be distinguished from other species in the genus by the dark brown band on its clypeus, the distinctive long orangish-brown hairs on its black eye field, the male's straight embolus and the presence of two fissure-like openings in the epigyne on the female. Taxonomy ''Stenaelurillus pilosus'' was first described by Wanda Wesołowska and Anthony Russell-Smith in 2011. It is one of over 500 species identified by the Polish arachnologist Wesołowska. The genus ''Stenaelurillus'' was first raised by Eugène Simon in 1886. The name relates to the genus name '' Aelurillus'', which itself derives from the Greek word for cat, with the addition of a Greek stem meaning narrow.It has be ...

Stenaelurillus Albus
''Stenaelurillus albus'' is a species of jumping spider in the genus '' Stenaelurillus'' that lives in India. It was first described in 2015 by Pothalil A. Sebastian, Pradeep M. Sankaran, Jobi J. Malamel and Mathew M. Joseph. The spider was first found in Kerala but has also been observed in Karnataka, including the Mookambika Wildlife Sanctuary and Parambikulam Tiger Reserve.

The female has a black oval cephalothorax which has a pattern of yellow bands and an oval abdomen that has yellow patches, the most pronounced three of which make a triangle shape, on a black background. The male differs in having a shiny black abdomen which has no patterns and a cephalothorax that is black with thick white stripes that mark the spider from front to back. This pattern distinguishes the species from others in the genus, including ''Ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Fauna Of Nigeria
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Fallow
Fallow is a farming technique in which arable land is left without sowing for one or more vegetative cycles. The goal of fallowing is to allow the land to recover and store Organic compound, organic matter while retaining moisture and disrupting pest life cycles and soil borne pathogens by temporarily removing their Host (biology), hosts. Crop rotation systems typically called for some of a farmer's fields to be left fallow each year. The increase in intensive farming, including the use of cover crops in lieu of fallow practices, has caused a loss of acreage of fallow land, as well as field margins, hedges, and wasteland. This has reduced biodiversity; fallows have been the primary habitat for farmland bird populations. Fallow syndrome Fallow syndrome is when a crop has insufficient nutrient uptake due to the lack of arbuscular mycorhizae (AM fungi) in the soil following a fallow period. Crops such as corn that are prone to fallow syndrome should not follow a period of fallow, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Paratype
In zoology and botany, a paratype is a specimen of an organism that helps define what the scientific name of a species and other taxon actually represents, but it is not the holotype (and in botany is also neither an isotype (biology), isotype nor a syntype). Often there is more than one paratype. Paratypes are usually held in museum research collections. The exact meaning of the term ''paratype'' when it is used in zoology is not the same as the meaning when it is used in botany. In both cases however, this term is used in conjunction with ''holotype''. Zoology In zoological nomenclature, a paratype is officially defined as "Each specimen of a type series other than the holotype.", ''International Code of Zoological Nomenclature'' In turn, this definition relies on the definition of a "type series". A type series is the material (specimens of organisms) that was cited in the original publication of the new species or subspecies, and was not excluded from being type material ...

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 ...
