Lasiodora Cryptostigma
''Lasiodora'' is a genus of tarantulas that was first described by Ludwig Carl Christian Koch in 1850. They are often very large; body lengths of up to , including the legs, are not unusual. They are found in South America, including the countries of Brazil, Bolivia, Costa Rica, Argentina and Uruguay. Diagnosis This genus can be distinguished from other tarantulas by the presence of hairs used for stridulation on the upper area of the coxae of leg 1 and 2. Males also own a triangular keel below the apex of the palpal bulb, females also have a sclerotized (hardened by sclerotin) area between the two sections of the spermathecae. Species it contains thirty-three species, found in Uruguay, Argentina, Bolivia, Brazil, and Costa Rica: *'' Lasiodora acanthognatha'' Mello-Leitão, 1921 – Brazil *'' Lasiodora benedeni'' Bertkau, 1880 – Brazil *'' Lasiodora boliviana'' (Simon, 1892) – Bolivia *'' Lasiodora brevibulba'' (Valerio, 1980) – Costa Rica *'' Lasiodora carinat ...

Ludwig Carl Christian Koch
Ludwig Carl Christian Koch (8 November 1825 – 1 November 1908) was a German entomologist and arachnologist. He was born in Regensburg, Germany, and died in Nuremberg, Germany. He studied in Nuremberg, initially law, but then turned to medicine and science. From 1850, he practiced as a physician in the Wöhrd district of Nuremberg. He is considered among the four most influential scientists on insects and spiders in the second half of the 19th century. He wrote numerous works on the arachinoids of Europe, Siberia, and Australia. His work earned him worldwide reputation as "Spider Koch". Sometimes confused with his father Carl Ludwig Koch (1778–1857), another famous arachnologist, his name is abbreviated L.Koch on species descriptions; his father's name is abbreviated C.L.Koch Pierre Bonnet. ''Bibliographia araneorum,'' (1945) Les frères Doularoude (Toulouse). Works ''Die Arachniden Australiens'' (1871-1883), his major work on Australian spiders, was completed by Euge ...

Spermatheca
The spermatheca (pronounced plural: spermathecae ), also called receptaculum seminis (plural: receptacula seminis), is an organ of the female reproductive tract in insects, e.g. ants, bees, some molluscs, oligochaeta worms and certain other invertebrates and vertebrates. Its purpose is to receive and store sperm from the male or, in the case of hermaphrodites, the male component of the body. Spermathecae can sometimes be the site of fertilization when the oocytes are sufficiently developed. Some species of animal have multiple spermathecae. For example, certain species of earthworms have four pairs of spermathecae—one pair each in the 6th, 7th, 8th, and 9th segments. The spermathecae receive and store the spermatozoa of another earthworm during copulation. They are lined with epithelium and are variable in shape: some are thin, heavily coiled tubes, while others are vague outpocketings from the main reproductive tract. It is one of the many variations in sexual reproduction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ralph Vary Chamberlin
Ralph Vary Chamberlin (January 3, 1879October 31, 1967) was an American biologist, ethnographer, and historian from Salt Lake City, Utah. He was a faculty member of the University of Utah for over 25 years, where he helped establish the School of Medicine and served as its first dean, and later became head of the zoology department. He also taught at Brigham Young University and the University of Pennsylvania, and worked for over a decade at the Museum of Comparative Zoology at Harvard University, where he described species from around the world. Chamberlin was a prolific taxonomist who named over 4,000 new animal species in over 400 scientific publications. He specialized in arachnids (spiders, scorpions, and relatives) and myriapods (centipedes, millipedes, and relatives), ranking among the most prolific arachnologists and myriapodologists in history. He described over 1,400 species of spiders, 1,000 species of millipedes, and the majority of North American centipedes, altho ...
