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 ...

Neoheterophrictus Crurofulvus
''Neoheterophrictus crurofulvus'' is a species of tarantula. It is also the type species of ''Neoheterophrictus'' and is found in the Western Ghats, India. Etymology The specific name ''crurofulvus'' is a mixture of two Latin words: ''cruro'' meaning "leg" or "appendage"; and ''fulvus'' meaning "tawny" or "yellowish-brown". This refers to the light brown colour of the legs of the female, which is not seen in any other Indian Theraphosid. Distinguishing features ''Neoheterophrictus crurofulvus'' is known from the male and female. The female is distinguished by the structure of the 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; there are two receptacles, which narrow at the apex; also upon the apex are a multitude of tiny lobes.

Neoheterophrictus Bhori
''Neoheterophrictus bhori'' is a species of tarantula. It is native to Parambiculam, Western Ghats, Cochin province, India. Etymology The species name comes from the name of Mr. J. Bhore, the Dewan of Cochin, who aided Frederic Henry Gravely in his scientific research. Characteristics This species is currently only known from the female. It is found in bamboo forest, which is unusual as few arthropods are found in such an environment. It differs from other species mainly by the spines on its legs; the first leg has a small inner apical spine on the tibia, and the second has the same spine only at an earlier stage and is accompanied by a mid-apical spine and an outer apical spine. It also lacks white setae on the extremities of the legs. It is brown, and slightly darker brown on the abdomen. The multi-lobular spermathecae are thinner than in ''Neoheterophrictus sahyadri'' and wider than in ''Neoheterophrictus uttarakannada'' or ''Neoheterophrictus crurofulvus ''Neoheterop ...

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 Sahyadri
''Neoheterophrictus sahyadri'' is a spider species in the genus ''Neoheterophrictus''. It was first described in 2012 by Manju Siliwal, Neha Gupta, and Robert John Raven. Its name "sahyadri" comes from the vernacular name for the Western Ghats, a mountain range in India where it was discovered. Characteristics The female is characterized by short and very stout 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 (2×) with 6-7 large contiguous lobes and black-green bodies. The male is characterized by the presence of a thick spine on the tibial spur, the palp embolus gently curving retrolaterally towards the tip, and the completely white metatarsi and tarsi on all of the legs.

Tarantula
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.

Palpal Bulb
The two palpal bulbs – also known as palpal organs and genital bulbs – are the copulatory organs of a male spider. They are borne on the last segment of the pedipalps (the front "limbs" of a spider), giving the spider an appearance often described as like wearing boxing gloves. The palpal bulb does not actually produce sperm, being used only to transfer it to the female. Palpal bulbs are only fully developed in adult male spiders and are not completely visible until after the final moult. In the majority of species of spider, the bulbs have complex shapes and are important in identification. Structure The palpal bulb of a mature male spider is borne on the last segment of the pedipalp. This segment usually has touch-sensitive hairs (setae) with nerves leading to them. The bulb itself is entirely without nerves, and hence without sensory organs and muscles, since these depend on nerves for their functioning, although some spiders have one or two muscles external to the bulb and ...

World Spider Catalog
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of individual web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History. After Platnick's retirement in 2014, the Natural History Museum of Bern (Switzerland) took over the catalog, converting it to a relational database. , 50,151 accepted species were listed. The order Araneae 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 dive ... (spiders) has the seventh-most species of all orders. The existence of the World Spider Catalog makes spiders the largest taxon with an online listing that is updated regularly. It ha ...
