Annandaliella pectinifera is a species of tarantula, a type of spider, in the subfamily Selenogyrinae. It is endemic to India. [1]
Fredrick Gravely described this species in 1935, placing it in the Ischnocolinae simply because "it seemed undesirable to form a special subfamily for so small a genus". [2] But now that the Selenogyrinae has been created, it has now been placed in this subfamily. [1]
Annandaliella pectinifera has stout stridulatory setae on the inside of both chelicerae, to form a primitive stridulatory organ, in the young and male specimens as well as the females. The male has unique colouration: brown, deepening in darkness as the height gets lower, and the underside having long golden hairs and reddish hair on the margin of the chelicerae. The embolus is long and slender, but is not very evenly curved and very curved at all. [2]
Annandaliella travancorica is a species of tarantula spider found in the Western Ghats of India. It was the first of three members of the genus Annandaliella to be described, therefore the type species.
Annandaliella is a genus of tarantulas that was first described by A. S. Hirst in 1909. As of December 2019 it contains three species endemic to India: A. ernakulamensis, A. pectinifera, and A. travancorica. They are selenogyrid tarantulas, meaning they have a stridulating organ on the inner side of the chelicerae, consisting of an oblique row of five strong spines in front of several weak spines.
Unicorn ("one horn", in Latin) is a genus of goblin spiders from South America, containing seven species that occur predominantly in high elevation, semi-desert regions of Bolivia, Chile, and Argentina. Individuals are relatively large for goblin spiders, measuring up to 3.0 mm (0.12 in) in body length. The genus name refers to a characteristic pointed projection between the eyes and jaws of males. In at least one species, broken-off tips of the male pedipalps have been found within the genitalia of females, postulated as a means of sperm competition. Unicorn possesses several traits that suggest it is a relatively "primitive" member of the Oonopidae, and is classified with other similar, soft-bodied goblin spiders in the subfamily Sulsulinae.
Tarantulas comprise a group of large and often ″hairy″ spiders of the family Theraphosidae. Currently, about 1,000 species have been identified. 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 urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.
Theraphosa apophysis is a species of spider in the family Theraphosidae, found in Venezuela and Brazil.
Zygoballus sexpunctatus is a species of jumping spider which occurs in the southeastern United States where it can be found in a variety of grassy habitats. Adult spiders measure between 3 and 4.5 mm in length. The cephalothorax and abdomen are bronze to black in color, with reddish brown or yellowish legs. The male has distinctive enlarged chelicerae and front femora. Like many jumping spiders, Z. sexpunctatus males exhibit ritualized courtship and agonistic behavior.
Menemerus bivittatus is a spider in the family Salticidae commonly known as the gray wall jumper. It is a pantropical species and is usually found on the walls of buildings or on tree trunks where it stalks its prey.
Gibbaranea bituberculata is a species of 'orbweavers' belonging to the family Araneidae, subfamily Araneinae.
Euphrictus spinosus is a tarantula, subfamily Selenogyrinae, first described by A.S. Hirst in 1908. It is only known from the male, and from the Dja River, Cameroon.
Euphrictus is a genus of tarantula which is found in Africa. It is part of the subfamily Selenogyrinae.
Annandaliella ermakulamensis is a species of tarantula in the subfamily Selenogyrinae. It is one of three species in the genus Annandaliella and the first to be described in 73 years. It is native to Ermakulam, Kerala State, India.
Bacillochilus is a monotypic genus of African tarantulas containing the single species, Bacillochilus xenostridulans. The genus and sole species were both described by R. C. Gallon in 2010, and is found in Angola. The name is a combination of the Ancient Greek "xénos" (ξενος), meaning "foreign" or "strange", and the Latin "stridulere", meaning "to creak". It is a reference to the unusual form of the stridulatory organ that distinguishes it from other members of the subfamily Harpactirinae.
The Eumenophorinae are a subfamily of tarantula spiders. They are known from genera distributed across Africa, southwestern countries in Saudi Arabia, and Madagascar and the associated islands.
Selenogyrus austini is a theraphosid spider. As of February 2016, it is a member of the selenogyrinae. It is native to Sierra Leone.
Selenogyrus is a genus of spider, or more specifically, selenogyrine theraphosid. The type species is Selenogyrus caeruleus.
Selenogyrus aureus is a species of tarantula, in the subfamily Selenogyrinae. It is endemic Sierra Leone.
Selenogyrus africanus is a species of tarantula, which is native to the Ivory Coast and is a member of the Selenogyrinae subfamily.
Pachistopelma rufonigrum is a species of theraphosid, contained within the Aviculariinae subfamily. It is endemic to Brazil.
Selenogyrus caeruleus is a species of tarantula native to Sierra Leone.
Archaea is an extinct genus of spiders in the family Archaeidae. As of October 2016, four species are placed in the genus. All have been found preserved in amber, either from the Baltic or Bitterfeld, Germany. First described in 1854, Archaea species have a distinctive "neck" separating the head from the thorax, and very long chelicerae ("jaws").
