Lutzomyia Adiketis
''Lutzomyia adiketis'' is an extinct species of sandfly in the moth fly subfamily Phlebotominae. ''L. adiketis'' is a vector of the extinct '' Paleoleishmania neotropicum'' and both species are solely known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola. History and classification The species is known solely from the holotype specimen, number # P-3–5, a complete female fly. The specimen is currently residing in the Poinar Amber Collection housed at the Oregon State University in Corvallis, Oregon. The specimen was collected from an unidentified amber mine in the Cordillera Septentrional between Puerto Plata and Santiago de los Caballeros. The specimen was first studied by noted amber researcher George Poinar Jr., from Oregon State University. Poinar published his 2008 type description in the journal ''Parasites & Vectors''. The specific epithet "''adiketis''" was coined by the author as a derivation from the Greek word ('), meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cordillera Septentrional
The Cordillera Septentrional is a mountain range that runs parallel to the north coast of the Dominican Republic, with extensions to the northwest as Tortuga island in Haiti, and to the southeast through lowlands to where it rises as the Sierra de Samaná on the Samaná Peninsula. The range's highest point is Diego de Ocampo mountain at , located near Santiago de los Caballeros in Santiago Province. There are several small plains between the range and the Atlantic Ocean The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe ... coastline. Rivers have short courses in the range, and most of them flow to the north into the Atlantic.

Flagellate
A flagellate is a cell or organism with one or more whip-like appendages called flagella. The word ''flagellate'' also describes a particular construction (or level of organization) characteristic of many prokaryotes and eukaryotes and their means of motion. The term presently does not imply any specific relationship or classification of the organisms that possess flagella. However, the term "flagellate" is included in other terms (such as "dinoflagellate" and "choanoflagellata") which are more formally characterized. Form and behavior Flagella in eukaryotes are supported by microtubules in a characteristic arrangement, with nine fused pairs surrounding two central singlets. These arise from a basal body. In some flagellates, flagella direct food into a cytostome or mouth, where food is ingested. Flagella often support hairs, called mastigonemes, or contain rods. Their ultrastructure plays an important role in classifying eukaryotes. Among protoctists and microscopic anima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleoleishmania
''Paleoleishmania'' is an extinct genus of kinetoplastids, a monophyletic group of unicellular parasitic flagellate protozoa. At present it is placed in the family Trypanosomatidae. The genus contains two species, ''Paleoleishmania neotropicum'' and the type species ''Paleoleishmania proterus''. The genus is known from the Albian aged Burmese amber deposits of northern Myanmar and the Burdigalian aged Dominican amber deposits on the island of Hispaniola. Etymology The genus name ''Paleoleishmania'' is derived from the Greek ''paleo'' meaning "old" and ''leishmania'' referencing the modern Leishmaniasis-causing genus ''Leishmania''. All trypanosomes are heteroxenous (requiring more than one obligatory host in order to complete life cycle) or are transmitted through some variation of a vector. ''Paleoleishmania proterus'' The genus was described in 2004 by George Poinar Jr. and Robert Poinar in the journal ''Protist'' from amastigotes, promastigotes and paramastigotes preserv ...

Trypanosomatid
Trypanosomatida is a group of kinetoplastid excavates distinguished by having only a single flagellum. The name is derived from the Greek ''trypano'' (borer) and ''soma'' (body) because of the corkscrew-like motion of some trypanosomatid species. All members are exclusively parasitic, found primarily in insects. A few genera have life-cycles involving a secondary host, which may be a vertebrate, invertebrate or plant. These include several species that cause major diseases in humans. Some trypanosomatida are intracellular parasites, with the important exception of Trypanosoma brucei. Medical importance The three major human diseases caused by trypanosomatids are; African trypanosomiasis (sleeping sickness, caused by ''Trypanosoma brucei'' and transmitted by tsetse flies), South American trypanosomiasis (Chagas disease, caused by '' T. cruzi'' and transmitted by triatomine bugs), and leishmaniasis (a set of trypanosomal diseases caused by various species of ''Leishmania'' trans ...

Alimentary Tract
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines. Food taken in through the mouth is digested to extract nutrients and absorb energy, and the waste expelled at the anus as feces. ''Gastrointestinal'' is an adjective meaning of or pertaining to the stomach and intestines. Most animals have a "through-gut" or complete digestive tract. Exceptions are more primitive ones: sponges have small pores ( ostia) throughout their body for digestion and a larger dorsal pore (osculum) for excretion, comb jellies have both a ventral mouth and dorsal anal pores, while cnidarians and acoels have a single pore for both digestion and excretion. The human gastrointestinal tract consists of the esophagus, stomach, and intestines, and is div ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proboscis
A proboscis () is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular mouthparts used for feeding and sucking. In vertebrates, a proboscis is an elongated nose or snout. Etymology First attested in English in 1609 from Latin , the latinisation of the Ancient Greek (), which comes from () 'forth, forward, before' + (), 'to feed, to nourish'. The plural as derived from the Greek is , but in English the plural form ''proboscises'' occurs frequently. Invertebrates The most common usage is to refer to the tubular feeding and sucking organ of certain invertebrates such as insects (e.g., moths, butterflies, and mosquitoes), worms (including Acanthocephala, proboscis worms) and gastropod molluscs. Acanthocephala The Acanthocephala or thorny-headed worms, or spiny-headed worms are characterized by the presence of an eversible proboscis, armed with spines, which it uses to pierce and ...

Lutzomyia (Lutzomyia)
''Lutzomyia'' is a genus of Phlebotominae, phlebotomine Sandfly, sand flies consisting of nearly 400 species, at least 33 of which have medical importance as Vector (epidemiology), vectors of human disease. Species of the genus ''Lutzomyia'' are found only in the New World, distributed in southern areas of the Nearctic realm, Nearctic and throughout the Neotropical realm. ''Lutzomyia'' is one of the two genera of the subfamily Phlebotominae to transmit the Leishmania parasite, with the other being ''Phlebotomus'', found only in the Old World. ''Lutzomyia'' sand flies also serve as vectors for the bacterial Oroya fever, Carrion's disease and a number of arboviruses. Evolution The genus, named after Adolfo Lutz, is known from the extinct Burdigalian (20–15 Mya (unit), mya) species ''Lutzomyia adiketis'' found as a fossil in Dominican amber on the island of Hispaniola. It is thought that species in the genus ''Lutzomyia'' all originated in the lowland forests to the east of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...
