picture info	Eduardo Ladislao Holmberg Eduardo Ladislao Holmberg (27 July 1852, in Buenos Aires – 4 November 1937) was an Argentine natural historian and novelist, one of the leading figures in Argentine biology. Together with Florentino Ameghino he undertook the inventory of Argentine flora and fauna, and explored all the ecoregions in the country, summarizing for the first time the biodiversity of its territory. The son of botanical aficionado and grandson of the Baron Holmberg, Holmburg accompanied Argentine '' Libertador'' Manuel Belgrano on his campaigns and introduced the cultivation of the ''camellia'' to Argentina. As director of the Buenos Aires Zoological Garden he greatly developed its scientific aspect, publishing booklets and providing printed media for a learned appreciation of its contents. He also directed the Natural History Cabinet of the University of Buenos Aires and published the standard reference works on botany and zoology used in his country for most of the 20th century.

	Senoculus ''Senoculus'' is a genus of araneomorph spiders in the family Senoculidae, and was first described by Władysław Taczanowski in 1872. It is the only genus in the family Senoculidae. Species it contains thirty-one species, found in South America, Guatemala, Panama, Mexico, and on Trinidad: ''Senoculus albidus'' ( F. O. Pickard-Cambridge, 1897) – Brazil ''Senoculus barroanus'' Chickering, 1941 – Panama ''Senoculus bucolicus'' Chickering, 1941 – Panama ''Senoculus cambridgei'' Mello-Leitão, 1927 – Brazil ''Senoculus canaliculatus'' F. O. Pickard-Cambridge, 1902 – Mexico to Panama ''Senoculus carminatus'' Mello-Leitão, 1927 – Brazil ''Senoculus darwini'' (Holmberg, 1883) – Argentina ''Senoculus fimbriatus'' Mello-Leitão, 1927 – Brazil ''Senoculus gracilis'' (Keyserling, 1879) – Guyana to Argentina ''Senoculus guianensis'' Caporiacco, 1947 – Guyana '' Senoculus iricolor'' (Simon, 1880) – Brazil '' Senoculus maronicus'' Taczanowski, 1872 (type) ...

	Araneomorphae The Araneomorphae (also called the Labidognatha) are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae (tarantulas and their close kin), where they point straight down. Araneomorphs comprise the vast majority of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations they can employ during prey capture. They have fewer book lungs (when present), and the females typically live one year. The Mygalomorphae have fangs that face towards the ground, and which are parallel to the long axis of the spider's body, thus they have only one orientation they can employ during prey capture. They have four pairs of book lungs, and the females often live many years. Image:Atrax robustus.jpg, This '' Atrax robustus'' shows the orientation of Myglamorphae fangs. Ima ...

picture info	Endemic Fauna Of Argentina Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Spiders Of Argentina 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 a separate ...
