Americobdella is a genus of carnivorous leeches from southern Chile, comprising only the species, Americobdella valdiviana.
Philippi, who originally classified A. valdiviana as an erpobdellid leech, noted that Americobdella valdiviana was similar to Trocheta (now synonymized with Erpobdella) "in both appearance and habit". [1] It is phylogenically between two major groups of leeches, the Rhynchobdellida and the Arhynchobdellida. [1] Recent work has suggested A. valdiviana is more closely related to the Erpobdelliformes than the Hirudiniformes. [1]
Americobdella valdiviana is a predator and has only rudimentary jaws. Because of these features, it was originally classified as an erpobdellid leech. [1] A. valdiviana is grey-coloured on the dorsal side with a yellowish ventral side. Whether eyes are present in this species is a matter of debate. While Philippi originally described Americobdella valdiviana as having no eyes, other authors have indicated that eyes are indeed present. [1]
A. valdiviana feeds on earthworms. [1]
The Juan Fernández fur seal is the second smallest of the fur seals, second only to the Galápagos fur seal. They are found only on the Pacific Coast of South America, more specifically on the Juan Fernández Islands and the Desventuradas Islands. There is still much that is unknown about this species. Scientists still do not know the average life span of this species, or the diet and behavior of males apart from the breeding season.
Rodolfo AmandoPhilippi was a German–Chilean paleontologist and zoologist. Philippi contributed primarily to malacology and paleontology. His grandson, Rodulfo Amando Philippi Bañados (1905-1969), was also a zoologist and in order to avoid confusion in zoological nomenclature, the elder is referred to as "Philippi [Krumwiede]" to distinguish him from his grandson "Philippi [Bañados]".
Darwin's fox or Darwin's zorro is an endangered canid from the genus Lycalopex. It is also known as the zorro chilote or zorro de Darwin in Spanish and lives on Nahuelbuta National Park, the Cordillera de Oncol, Cordillera Pelada in mainland Chile and Chiloé Island. This small, dark canine weighs 1.8 to 3.95 kg, has a head-and-body length of 48 to 59 cm and a tail that is 17.5 to 25.5 cm. Darwin's fox displays no key differences between male and female other than the fact that the male has a broader muzzle. Males display no territorial behavior and aren't aggressive towards other males roaming around their territory.
Valdivia is a city and commune in southern Chile, administered by the Municipality of Valdivia. The city is named after its founder, Pedro de Valdivia, and is located at the confluence of the Calle-Calle, Valdivia, and Cau-Cau Rivers, approximately 15 km (9 mi) east of the coastal towns of Corral and Niebla. Since October 2007, Valdivia has been the capital of Los Ríos Region and is also the capital of Valdivia Province. The national census of 2017 recorded the commune of Valdivia as having 166,080 inhabitants (Valdivianos), of whom 150,048 were living in the city. The main economic activities of Valdivia include tourism, wood pulp manufacturing, forestry, metallurgy, and beer production. The city is also the home of the Austral University of Chile, founded in 1954 and the Centro de Estudios Científicos.
Physidae, commonly called the bladder snails, is a family of small air-breathing freshwater snails, aquatic pulmonate gastropod molluscs in the superfamily Lymnaeoidea.
The Atacama myotis is a species of vesper bat in the family Vespertilionidae. It is found in Chile and Peru, an example ecoregion of occurrence being the Chilean matorral.
Irenomys tarsalis, also known as the Chilean climbing mouse, Chilean tree mouse, or long-footed irenomys, is a rodent found in Chile, from about 36° to 46°S, and in adjacent Argentina, mainly in forests. It is a large, long-tailed, soft-furred mouse characterized by grooved upper incisors and specialized molars with transverse ridges, divided by deep valleys, which are connected by a transverse ridge along the midline of the molars.
Latua pubiflora(Griseb.) Baillon, is the single species of the monotypic genus LatuaPhil., endemic to the coastal mountains of southern Chile. A shrub or small tree to 10 m in height, bearing attractive, magenta-to-red, hummingbird-pollinated flowers, it is extremely poisonous – hallucinogenic (deliriant) in smaller doses – due to tropane alkaloid content and is used by Chilean machi (shamans) of the Mapuche–Huilliche people in traditional medicine, as a poison and to enter trance states. Its elegant flowers and yellow tomato-like fruit are attractive enough to merit its cultivation as an ornamental.
Penion is a genus of large marine snails, commonly known as siphon whelks, classified within the mollusc family Austrosiphonidae, the true whelks.
Unicorn ("one horn", in Latin) is a genus of goblin spiders from South America, containing seven species that occur predominantly in high elevation, semi-desert regions of Bolivia, Chile, and Argentina. Individuals are relatively large for goblin spiders, measuring up to 3.0 mm (0.12 in) in body length. The genus name refers to a characteristic pointed projection between the eyes and jaws of males. In at least one species, broken-off tips of the male pedipalps have been found within the genitalia of females, postulated as a means of sperm competition. Unicorn possesses several traits that suggest it is a relatively "primitive" member of the Oonopidae, and is classified with other similar, soft-bodied goblin spiders in the subfamily Sulsulinae.
The Chilean National Museum of Natural History is one of three national museums in Chile, along with the Museum of Fine Arts and the National History Museum. It is located in Quinta Normal Park. Founded on September 14, 1830 by the French naturalist Claudio Gay, the director of the Museum and the Botanical garden was another Frenchman Jean-François Dauxion-Lavaysse.
Leeches are segmented parasitic or predatory worms that comprise the subclass Hirudinea within the phylum Annelida. They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid, and the coelom, the spacious body cavity found in other annelids, is reduced to small channels.
Rhodolirium is a small South American genus in the tribe Hippeastreae of the family Amaryllidaceae. Although originally described by Philippi in 1858 it has long remained buried in other taxa, principally Hippeastrum and more recently Rhodophiala. Only in recent years has it been rehabilitated.
Chiasognathus grantii is a species of stag beetle found in Argentina and Chile. It is known as Darwin's beetle, Grant's stag beetle, or the Chilean stag beetle.
Apoplania valdiviana is a species of moth belonging to the family Neopseustidae. It was described by Davis and Nielsen in 1985. It is known from the south-western part of the Neuquen Province of Argentina and the eastern part of the Osorno Province and the Cautin Province in Chile.
Caponiidae is a family of ecribellate haplogyne spiders that are unusual in a number of ways. They differ from other spiders in lacking book lungs and having the posterior median spinnerets anteriorly displaced to form a transverse row with the anterior lateral spinnerets. Most species have only two eyes, which is also unusual among spiders. A few species of Caponiidae variously have four, six or eight eyes. In some species the number of eyes will increase when the spiderling changes its skin as it grows towards adulthood.
Chilecomadia is a genus of moths in the family Cossidae.
The annelids, also known as the segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments.
Eysyslopterus is a genus of eurypterid, an extinct group of aquatic arthropods. Eysyslopterus is classified as part of the family Adelophthalmidae, the only clade within the derived ("advanced") Adelophthalmoidea superfamily of eurypterids. One fossil of the single and type species, E. patteni, has been discovered in deposits of the Late Silurian period in Saaremaa, Estonia. The genus is named after Eysysla, the Viking name for Saaremaa, and opterus, a traditional suffix for the eurypterid genera, meaning "wing". The species name honors William Patten, an American biologist and zoologist who discovered the only known fossil of Eysyslopterus.
Valdiviomyia is a genus of hoverflies from the family Syrphidae, in the order Diptera.
