Cilantica
''Cilantica'' is a genus of Indian tarantulas that was described by Mirza in 2024. Two members from '' Haploclastus'' were transferred into the genus along with one new species. They are only found in the Palakkad Gap. Etymology The name is the Latinized form of the Tamil word for spider, s''ilanthi'' (சிலந்த). Diagnosis Large spiders, measuring 25–38 mm. The carapace is oval, hairy, with two distinct setae-free bands on each side of the caput. The fovea is shallow and curved. The posterior sternal sigilla are not very deep and are placed near the center. The retrolateral face of the chelicerae has parallel rows of thick, curved setae. The prolateral face of the maxilla features stout black bristles arranged along the suture line. Spines are present on legs II–IV. The spermathecae are mound-shaped. Females carry the egg sac under their chelicerae. Ecology The burrow is typically found on mud walls and embankments along streams, with a tubular extension made ...

Haploclastus
''Haploclastus'' is a genus of Indian tarantulas (family Theraphosidae) that was first described by Eugène Simon in 1892. The genus '' Phlogiodes'' has been synonymized with ''Haploclastus'' by some authors. Description They can be distinguished by the deep and procured fovea, with horizontal thornlike hairs in two or three rows above and below the maxillary. These hairs have a long tapering, they are modified and aligned vertically in a "diffuse" pattern on the maxilla. Taxonomy The genus ''Haploclastus'' was first described by Eugène Simon in 1892. In 1899, Reginald Pocock erected the genus ''Phlogiodes''. He described two species, ''Phlogiodes validus'' from a male specimen and ''Phlogiodes robustus'' from a female specimen. The relationship between the genera ''Haploclastus'' and ''Phlogiodes'' has varied; in 1985, Raven sank ''Phlogiodes'' into ''Haploclastus''. In 2010, the two ''Phlogiodes'' species were synonymized and transferred to ''Haploclastus'' as ''Haplocla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theraphosidae
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,100 species have been identified, with 166 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.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
