Neoheterophrictus Uttarakannada
''Neoheterophrictus uttarakannada'' is a species of spiders in the genus ''Neoheterophrictus'' from India. It was first described in 2012 by Manju Siliwal, Neha Gupta, & Robert John Raven. Its name comes from the place where it was discovered, Uttara Kannada. Characteristics The species is only known from the female. It is identified by two short 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 ...e receptacles (which show some constriction at the ends), with multiple (6-7) large contiguous lobes at the end. Its legs have short yellow-orange tarsal hairs, and the full body colour is grey-brown. It makes temporary holes under stones.

Neoheterophrictus
''Neoheterophrictus'' is a genus of tarantula in the family Theraphosidae. It comprises seven species, all found in India. Characteristics ''Neoheterophrictus'' is similar to ''Heterophrictus'' and ''Plesiophrictus'', however the females differ by having a different spermathecae structure, which have two receptacles with many lobes/termini at the end. Males are distinguished from ''Plesiophrictus'' by the absence of a tegular keel on the male palpal bulb. It occurs in the Western Ghats, India. Etymology The name is a combination of two words ''neo'' and ''heterophrictus'', ''neo'' in Latin meaning "new" and ''Heterophrictus'' being a genus name within the family Theraphosidae. Species , the World Spider Catalog recognized seven species. All are restricted to India. *'' Neoheterophrictus amboli'' Mirza & Sanap, 2014 *''Neoheterophrictus bhori'' (Gravely, 1915) *''Neoheterophrictus crurofulvus'' Siliwal, Gupta & Raven, 2012 *''Neoheterophrictus madraspatanus'' (Gravely, 1 ...

Uttara Kannada
Uttara Kannada is a district in the Indian state of Karnataka. Uttara Kannada District is a major coastal district of Karnataka, and currently holding the title of the largest district in Karnataka.

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 reproduct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theraphosidae
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,040 species have been identified, with 156 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes. Overview Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.Pomeroy, R. (2014, February 4). Pub.

Spiders Described In 2012
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 ...
