Schendylops Ramirezi
''Schendylops ramirezi'' is a species of soil centipede in the family Schendylidae. This centipede is notable as the species with the fewest legs recorded in the order Geophilomorpha for each sex (27 pairs of legs for males, 29 leg pairs for females). This species is also the smallest in the genus ''Schendylops'', reaching only in length. Discovery This species was first described in 2013 by the Argentine myriapodologist Luis Alberto Pereira of the Universidad Nacional de La Plata based on specimens collected in 1999 in Brazil. These specimens include a female holotype, five paratypes (three males and two females), and nineteen other specimens (fifteen females and four males), including five subadults and fourteen juveniles. The species is named for the Argentine arachnologist Martin Javier Ramirez of the Museo Argentino de Ciencias Naturales in Buenos Aires, who collected all the specimens. These specimens are deposited at the Museu de Zoologia da Universidade de São Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ilha Grande
Ilha Grande (), or "big island", is a forested island located around 12 km (7.5 mi) off of the Atlantic coast of Angra dos Reis, Rio de Janeiro, Brazil, and about 243 km (151 mi) from São Paulo. The highest point on Ilha Grande is the tall Pico da Pedra D'Água. History For almost a century, the Brazilian government declared the island off-limits, banning unauthorized entry, as it had contained an immigration quarantine station and, later, a maximum-security prison (''Colônia Penal de Dois Rios'', later known as ''Instituto Penal Cândido Mendes''). The Cândido Mendes Penal Colony, which housed some of the most dangerous offenders in Brazil, was closed in 1994. On 1 January 2010, devastating mudslides killed at least 19 people on the island. On 5 July 2019, Ilha Grande and Paraty were inscribed as a UNESCO World Heritage Site. Environment Ilha Grande and Paraty are contained within the of Tamoios Environmental Protection Area (APA), created in 1982. The main island ( ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is ...

Maxilla (arthropod Mouthpart)
In arthropods, the maxillae (singular maxilla) are paired structures present on the head as mouthparts in members of the clade Mandibulata, used for tasting and manipulating food. Embryologically, the maxillae are derived from the 4th and 5th segment of the head and the maxillary palps; segmented appendages extending from the base of the maxilla represent the former leg of those respective segments. In most cases, two pairs of maxillae are present and in different arthropod groups the two pairs of maxillae have been variously modified. In crustaceans, the first pair are called maxillulae (singular maxillula). Modified coxae at the base of the pedipalps in spiders are also called "maxillae", although they are not homologous with mandibulate maxillae. Myriapoda Millipedes In millipedes, the second maxillae have been lost, reducing the mouthparts to only the first maxillae which have fused together to form a gnathochilarium, acting as a lower lip to the buccal cavity and the ...

Seta
In biology, setae (; seta ; ) are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Depending partly on their form and function, protostome setae may be called macrotrichia, chaetae, Scale (insect anatomy), scales, or Common name, informally, hairs. The setal membrane is not Cuticle, cuticularized, so movement is possible. Annelid setae are stiff bristles present on the body. They allow earthworms and their relatives to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (the group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. The setae on polychaete worms are referred to as chaeta due to their differing morphology. Crustaceans have mechano- and chemos ...

Antenna (biology)
An antenna (plural: antennae) is one of a pair of appendages used for Sensory system, sensing in arthropods. Antennae are sometimes referred to as ''feelers''. Antennae are connected to the first one or two Segmentation (biology), segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing tactition, touch, air motion, heat, vibration (sound), and especially insect olfaction, smell or gustation, taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate (biology), substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sternum (arthropod Anatomy)
The sternum (: sterna) is the ventral portion of a segment of an arthropod thorax or abdomen. In insects, the sterna are usually single, large sclerites, and external. However, they can sometimes be divided in two or more, in which case the subunits are called sternites, and may also be modified on the terminal abdominal segments so as to form part of the functional genitalia, in which case they are frequently reduced in size and development, and may become internalized and/or membranous. For a detailed explanation of the terminology, see Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with those of arthropods.Sørensen, M. V. et al. Phylogeny of Kinorhyncha based on morphology and two molecular loci. PLoS One 10, 1–33 (2015). Ventrites are externally visible sternites. Usually the first sternite is covered up, so that ventrite numbers do not correspond to sternite numbers. The term is also used in other arthropod groups such as crustaceans, ...

Dinogeophilus Oligopodus
''Dinogeophilus oligopodus'' is a species of soil centipede in the family Schendylidae. This centipede ranges from 4.5 to 5.5 mm in length, the smallest size recorded not only in the order Geophilomorpha but also in any epimorphic order of centipedes. This species is also notable as one of only six species in the order Geophilomorpha to feature only 29 pairs of legs and one of only two species to include females with only 29 pairs, the minimum number recorded for females in this order. Discovery and distribution The zoologist Luis Alberto Pereira first described this species in 1984, based on five specimens collected near Puerto Iguazu, close to the Paraná river, in the Missiones province of Argentina. These specimens include a male holotype, three male paratypes, and one female allotype. These specimens were found in soil rich with humus, with leaf litter and abundant roots from jungle vegetation. Since the original description of ''D. oligopodus'', Pereira and three bio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schendylops Oligopus
''Schendylops oligopus'' is a species of soil centipede in the family Schendylidae. This species is notable as one of only two species in the order Geophilomorpha known to include centipedes with only 27 pairs of legs, the minimum number recorded in this order. Furthermore, ''S. oligopus'' was the first species in this order found to feature so few legs. Discovery This species was first described in 1995 by the biologists Luis Alberto Pereira, Alessandro Minelli, and Francesco Barbieri. The original description of this species is based on a large sample, including a female holotype, a male allotype, nine paratypes (eight females and one male), and fourteen other specimens (thirteen females and one male). All specimens were collected in 1982 or 1983 from the Adolfo Ducke Forest Reserve in Amazonas state in Brazil. Pereira and his coauthors named the species ''oligopus'' in light of the small number of legs observed in these specimens: All the females had only 31 pairs of l ...
