Attulus Inexpectus
''Attulus inexpectus'' is a species of spider from family Salticidae, found in from Europe (including southern England) to central Asia. It was previously misidentified as '' Attulus rupicola'' (syn. ''Sitticus rupicola''). Until 2017, it was placed in the genus ''Sitticus''. Description ''Attulus inexpectus'' females have a body length of about , males being slightly smaller at about . The fourth leg is the longest, about in females and about in males. Both sexes are generally brown to dark brown in overall coloration, males being darker than females. Both the carapace and abdomen have stripes and patterns formed by whitish or otherwise paler hairs, the carapace pattern being more distinct in males, with three longitudinal whitish stripes and a similarly coloured lateral border with the posterior part having a short line extending inwards. Taxonomy ''Attulus inexpectus'' was first described in 1997 by Dimitri Logunov and Torbjörn Kronestedt (as ''Sitticus inexpectus''). T ...

Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Jumping Spider
Jumping spiders are a group of spiders that constitute the family (biology), 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 Invertebrate trachea, 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 Anatomical terms of location, anterior median pair being particularly large. Distinguishing characteristics Jumping spiders are among the easiest to distinguish from similar spider f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attulus Rupicola
''Attulus'' is a genus of jumping spiders that was first described by Eugène Louis Simon in 1889. The name is a diminutive form of a common prefix for salticid genera, '. Taxonomy In 1889, Eugène Simon separated the genus ''Attulus'' from the genus '' Attus''. The correct name of the type species involves some taxonomic complexity. Simon gave ''Attus cinereus'' Westring, 1861 as the type of the genus. However, this name had already been used by Walckenaer in 1837 for a different species, so Simon's 1871 replacement name ''Attus helveolus'' is used instead. ''A. helveolus'' is now regarded as the same species as ''Attus distinguendus'', described by Simon in 1868, so having priority as a name. Thus the type species is currently known as ''Attulus distinguendus''. Within the family Salticidae, ''Attulus'' is placed in the tribe Sitticini (the sitticines). The taxonomy of the tribe and the genus ''Attulus'' has been subject to considerable uncertainty; some species changed g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Dmitri V
Dmitri (russian: Дми́трий); Church Slavic form: Dimitry or Dimitri (); ancient Russian forms: D'mitriy or Dmitr ( or ) is a male given name common in Orthodox Christian culture, the Russian version of Greek Demetrios (Δημήτριος ''Dēmētrios'' ). The meaning of the name is "devoted to, dedicated to, or follower of Demeter" (Δημήτηρ, ''Dēmētēr''), "mother-earth", the Greek goddess of agriculture. Short forms of the name from the 13th–14th centuries are Mit, Mitya, Mityay, Mit'ka or Miten'ka (, or ); from the 20th century (originated from the Church Slavic form) are Dima, Dimka, Dimochka, Dimulya, Dimusha etc. (, etc.) St. Dimitri's Day The feast of the martyr Saint Demetrius of Thessalonica is celebrated on Saturday before November 8 ld Style October 26 The name day (именины): October 26 (November 8 on the Julian Calendar) See also: Eastern Orthodox liturgical calendar.

Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

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 ...

Saltmarsh
A salt marsh or saltmarsh, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides. It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the salt marsh in trapping and binding sediments. Salt marshes play a large role in the aquatic food web and the delivery of nutrients to coastal waters. They also support terrestrial animals and provide coastal protection. Salt marshes have historically been endangered by poorly implemented coastal management practices, with land reclaimed for human uses or polluted by upstream agriculture or other industrial coastal uses. Additionally, sea level rise caused by climate change is endangering other marshes, through erosion and submersion of otherwise tidal marshes. However, recent ackn ...

Sitticini
The Sitticini are a tribe of spiders in the family Salticidae (jumping spiders). The tribe has been divided into two subtribes, Aillutticina, with five Neotropical genera, and Sitticina, with five genera from Eurasia and the Americas. One genus is unplaced within the tribe. The taxonomy of the tribe has been subject to considerable uncertainty. It was clarified in 2020. Description The group is now primarily defined by molecular phylogenetic analysis. However, members can be distinguished from other salticids by the fourth leg being much longer than the third and by the absence of the retromarginal cheliceral tooth. Taxonomy The group was first described by Eugène Simon in 1901, under the name "Sitticeae". It was treated as the subfamily Sitticinae by various authors before being reduced to the tribe Sitticini by Wayne Maddison in 2015. The taxonomy of the tribe has been subject to considerable uncertainty; generic boundaries were changed repeatedly between 2017 and 2020. ...
