The two-striped jumper, or Telamonia dimidiata, is a jumping spider found in various Asian tropical rain forests, in foliage in wooded environments.
Females can reach a body length of 9–11 mm (0.35–0.43 in), males can reach a length of 8–9 mm (0.31–0.35 in). The female is light yellowish, with a very white cephalus and red rings surrounding the narrow black rings around the eyes. Two longitudinal bright red stripes are present on the opisthosoma. [3] The male is very dark, with white markings, and red hairs around the eyes. They appear in Singapore, Indonesia, Pakistan, Iran, India, and Bhutan. T. dimidiata produces no toxin significant to humans.
Since 1999, the spider has been the subject of an email hoax claiming that it was a fatal spider found lurking under toilet seats in North Florida. [4] This hoax was a rehashing of an older email circulated in 1999 with similar claims, except under the name "South American Blush Spider (arachnius gluteus[ sic ])" - literally "butt spider". Similar email hoaxes (with details of the original changed) occurred in other parts of the world, alleging the same falsity in the recipients' countries. Lately[ when? ] it has also appeared on Facebook, also including a picture of the arachnid. Posts commonly report of it being found world-round, suggesting everyone must take precautions. [5] No such events appear to have occurred, and the story is considered an urban legend. [6] [7] [8] The false rumor has since spread to websites such as Twitter, Facebook and Tumblr in 2012. Now the same hoax is circulating on WhatsApp (2018). The hoax has also been seen on Facebook in 2019.
Telamonia is a genus of jumping spiders that was first described by Tamerlan Thorell in 1887. They are colorful spiders, with patterns that vary considerably between sexes and species. Two longitudinal stripes along the abdomen are common, and the carapace is often colored. They have a slender opisthosoma and long legs.
Viciria is a genus of jumping spiders that was first described by Tamerlan Thorell in 1877.
Langona mediocris is a species of jumping spider in the genus Langona that lives in Zimbabwe. The male was first described by Wanda Wesołowska in 2000. The female has not been identified. The spider is large and brown-black with a carapace between 3 and 3.4 mm long and a abdomen between 2.7 and 3.1 mm. The carapace has two converging white stripes while the abdomen has a single stripe. The legs are orange and the pedipalps yellow. As is typical for the genus, the chelicerae are toothless. The long, thin embolus is hidden within a pocket in the cymbium and has a spiralled tip. The male differs from the similar Langona bitumorata by the single bump on its palpal bulb.
Phintella paludosa is a species of jumping spider in the genus Phintella that lives in Africa. It was first described in 2012 from a holotype discovered in Cross River State, Nigeria, by Wanda Wesołowska and G. B. Edwards, and was subsequently also found in Ivory Coast. The species was first seen in a swamp, so the species name is derived from the Latin for marshy. The spider is small, with a brown carapace and almost black abdomen. The female is smaller than the male. It is similar to the related Phintella aequipes but can be distinguished by the thick short embolus in the male of the species and the very small epigyne with copulatory openings at the rear in the female.
Phintella africana is a species of jumping spider in the genus Phintella that lives in Ethiopia. The female of the species was first described in 2008 by Wanda Wesołowska and Beata Tomasiewicz. The spider, which is named after the continent where it was found, is small and brown, with a mottled brown and yellow abdomen 2.4 mm (0.094 in) long. It lives in grasslands.
Phintella lucida is a species of jumping spider in the genus Phintella that lives in Ethiopia and Kenya. The female of the species was first described in 2008 by Wanda Wesołowska and Beata Tomasiewicz and the male by Angelika Dawidowicz and Wesołowska in 2016. The spider is large for the genus, and the female larger than the male with an abdomen that is up to 3.2 mm (0.13 in) in length. It is yellow, with brown spots on the abdomen, the lighter colour recognised in the name of the species, which recalls the Latin word for light.
Phintella incerta is a species of jumping spider in the genus Phintella that lives in the Mkomazi Game Reserve in Tanzania. The female of the species was first described in 2000 by Wanda Wesołowska and Anthony Russel-Smith. The spider, is small with a light brown carapace, a greyish-beige abdomen that has three stripes, and a distinctive sclerotized epigyne.
Aelurillus desertus is a species of jumping spider in the genus Aelurillus that is endemic to the United Arab Emirates. It was first described in 2010 by Wanda Wesołowska and Antonius van Harten. Initially only the male was described, the female following ten years later. The spider was originally classified in the genus Rafalus but was moved to its current genus at the same time as the female description was first published. The species is medium-sized with cephalothorax that is between 2.8 and 3.3 mm long and a abdomen that is between 2.8 and 4.8 mm long. The female is larger than the male. The carapace has a distinctive stripe. The female has three darker spots on the abdomen. The species can be distinguished by the existence of a triangular lobe on the palpal bulb on the male and the way that the copulatory openings are close to the rear of the epigyne on the female.
Plexippus fuscus is a species of jumping spider in the genus Plexippus that lives in Guinea. It was first described in 2002 by Christine Rollard and Wanda Wesołowska. Only the female has been described. It is a medium-sized spider, with a dark brown carapace typically 3.4 mm (0.13 in) long and a reddish-brown abdomen that is 2.3 mm (0.091 in) long. Both the carapace and abdomen are covered in dark brown hairs. The abdomen has a yellow marking like a belt. Although superficially similar to other species in the genus like Plexippus paykulli, it can be distinguished by the presence of a long thin pocket in the epigyne and significant sclerotisation on the edges of the copulatory openings, which are also wider than other Plexippus spiders.
Plexippus lutescens is a species of jumping spider in the genus Plexippus that lives in Namibia and Zimbabwe. It was first described in 2002 by Wanda Wesołowska. Only the male has been described. In 2017, Jerzy Prószyński declared it should be reclassified as the spider has a different palpal bulb to others in the genus, but this was not been undertaken. It is a medium-sized spider, with a cephalothorax typically 3.3 mm (0.13 in) long and an abdomen that is 4 mm (0.16 in) long. The dark brown carapace has three white stripes and the reddish-brown abdomen has a single stripe of lighter brown. The spider has a short tibial apophysis and thin embolus. It lacks the lateral lobe on the palpal bulb that is visible on other species in the genus.
Plexippus minor is a species of jumping spider in the genus Plexippus that lives in the United Arab Emirates. The male was first described by Wanda Wesołowska and Antonius van Harten in 2010 and the female in 2020. The spider is medium-sized with a cephalothorax between 3.1 and 3.8 mm long and an abdomen between 3.3 and 4.1 mm long. It has a shape and colouring typical of the genus. The male has a orange carapace while the female is brownish-fawn. The copulatory organs distinguish it from related species, particularly the male's shorter embolus and tibial apophysis and the female's wide pocket on its epigyne.
Phintella lajuma is a species of jumping spider in the genus Phintella that lives in South Africa. It was first described in 2013 by Charles Haddad and Wanda Wesołowska, and given a name to reflect the fact that it was first found in the forests around Lajuma Mountain in Soutpansberg. Only the female has so far been described. The spider is medium-sized and lighter in colour than its relative Phintella lucida. It has a light brown carapace and yellow beige abdomen that has a pattern of linesand patches. The epigyne is distinctively large and has a plate at the rear.
Phintella parva is a species of jumping spider in the genus Phintella that lives in China, Japan, Korea and Russia.The species was first described by Wanda Wesołowska in 1981 based on a holotype from North Korea. However, retrospectively; it was recognised that other examples of the spider had been previously collected and, at one time, a description published without a species name. The spider is small, between 3.5 and 4 mm long, and yellow. The abdomen has a striped pattern and the carapace has circular markings, but the most distinguishing difference between this species and other members of the genus are the sexual organs, particularly the short curved embolus on the male and long straight insemination ducts in the female.
Phintella pygmaea is an endemic species of jumping spider in the genus Phintella that lives in China. It was first described in 1981 by Wanda Wesołowska from a holotype discovered in Guangdong. Only the female has been described. The spider is small, with a brown cephalothorax and yellow abdomen. It has distinctive half-crescent markings on the cephalothorax and a ridge marked by two depressions on the small epigyne.
Phintella lunda is a species of jumping spider in the genus Phintella that lives in Angola. It was first described in 2010 by Wanda Wesołowska, and given a name to reflect the fact that it was first found in Lunda Sul Province. The spider is medium-sized and a similar shape to others in the genus. It has a very dark brown carapace that has edge markings and a greyish-brown abdomen that has streaks on the top and sides, but the main distinguishing feature are the copulatory organs. The male has a distinctive straight side to its palpal bulb, while the female has am epigyne which has two pockets and copulatory openings in cups.
Yimbulunga foordi is the type species of the genus Yimbulunga. It is a species of jumping spider species that lives in South Africa. The male was described in 2014 by Wanda Wesołowska, Galina Azarkina and Anthony Russell-Smith. The female has not been identified. The spider is very small, with a carapace that is 1.8 mm (0.071 in) long and an abdomen 1.4 mm (0.055 in) long. Both the carapace and abdomen are rounded, which is reflected in the genus name, the Zulu word for spherical. The species is named for the arachnologist Stefan Foord. The pedipalps are brown with a small lobe on the palpal bulb and a thin embolus that coils all the way round. The shape of the embolus and the overall stout shape of the spider differentiate the species.
Phintella kaptega is a species of jumping spider in the genus Phintella that lives in Kenya. The species is named after the area around the Kaptega river where it was first found. The spider was first described in 2016 by Angelika Dawidowicz and Wanda Wesołowska in 2016, and is distinguished by the large pockets in the female's epigyne. It is a small spider with a light brown carapace that has a dark line along its edge. The abdomen is between 1.95 and 2.2 mm long and has light brown markings on a yellow background.
Phintella caledoniensis is a species of jumping spider in the genus Phintella that lives in New Caledonia. First described in 2009 by Barbara Patoleta, it was named after the island where it was found. The spider is small and has a brown cephalothorax with patches, the female being generally darker, and a grey or grey-brown abdomen. The female has distinctive bean-shaped spermatheca and the male a long and thin embolus.
Padilla wandae is a species of jumping spider in the genus Padilla that lives in Madagascar. The species was first described in 2020 by Galina Azarkina and Charles Haddad. It is a medium-sized spider, with a brown carapace that is between 1.55 and 1.75 mm long, and a yellow abdomen that has a length of between 1.9 and 2.55 mm. The female is larger than the male. Although generally they have similar overall colouring and a single stripe on the carapace of both sexes, the female has one stripe on the abdomen and the male has two. The male palpal bulb has a hump in the middle and a coiled embolus. The female has an epigyne atrium that is longer than it is wide. The spider is similar to the related Padilla cornuta, but differs in lacking the chelicerae horns of the other species.
Phintella occidentalis is a species of jumping spider in the genus Phintella that lives in Ivory Coast. First described by Wanda Wesołowska and Anthony Russell-Smith in 2022, the species is named after the Latin word for western as it is found in West Africa. The spider is small, with a cephalothorax between 2.3 and 2.8 mm long and an abdomen that is between 3.1 and 3.5 mm long. The female is smaller than the male. The carapace is brown, the female light and the male dark. The abdomen is yellow and is marked by two wide brown stripes on the female and a grey streak on the male. It is the abdominal pattern that most clearly distinguishes the species from others in the genus. The copulatory organs are also different. The male has a longer tibial apophysis, or appendage and the female has seminal ducts that diverge and then converge.
