Asemonea maculata is a species of jumping spider in the genus Asemonea that is endemic to Ivory Coast. The spider was first defined in 1980 by Fred Wanless. It is a small spider, with a carapace that is between 2.08 and 2.10 mm (116 and 116 in) long and an abdomen typically 2.4 mm (18 in) long. The carapace is amber to whitish-yellow and the abdomen whitish-yellow, both with black markings. It is similar to the related species Asemonea pinangensis and Asemonea tanikawai , but can be distinguished by the tibia on the male pedipalp. The female has not been described.

Taxonomy

Asemonea maculata is a jumping spider that was first described by Fred Wanless in 1980. [1] He allocated the species to the genus Asemonea , first raised by Octavius Pickard-Cambridge in 1869. The genus is related to Lyssomanes . [2] Molecular analysis demonstrates that the genus is similar to Goleba and Pandisus . [3] In Wayne Maddison's 2015 study of spider phylogenetic classification, the genus Asemonea was the type genus for the subfamily Asemoneinae, split from Lyssomaninae. [4] A year later, in 2016, Jerzy Prószyński named it as the type genus for the Asemoneines group of genera, which was also named after the genus. [5]

Description

The spider is small, with a typical total length of between 4.56 and 4.7 mm (316 and 316 in). The male has a carapace that is between 2.08 and 2.10 mm (116 and 116 in) long and typically 1.8 mm (116 in) wide. [6] It is generally pale amber in colour, tending towards a more whitish-yellow in the eye field. The majority of the eyes are surrounded by black markings. The clypeus is pale yellow with a dark band across it and a thin covering of white hairs. The chelicerae, labium and the remainder of the mouthparts are pale yellow. The sternum is a shiny whitish-yellow. The abdomen is whitish-yellow with black spots and slightly iridescent. [7] It is typically 2.4 mm (18 in) long. [6] The spinnerets are whitish-yellow, as are the legs, although these have black stripes and other dark markings. The pedipalp is distinctive, particularly the enlarged tibia. [7] The female has not been described. [1]

The species is similar in colour to Asemonea murphyi , particularly in the spots and bars on its abdomen. [8] The spider also resembles both Asemonea pinangensis and Asemonea tanikawai but differs in the form of its pedipalp. [9]

Behaviour

Asemonea spiders rarely jump. Instead, they generally walk and run. They spin sheet webs on the underside of leaves, where they also lay their eggs. [10] Although predominantly a diurnal hunter, the spider is also likely to eat nectar if it is available. [11] [12]

Distribution and habitat

Asemonea maculata is endemic to Ivory Coast. [1] The holotype was found near the Bandama River in vegetation. [6]

<i>Aelurillus mirabilis</i> Species of spider

Aelurillus mirabilis is a species of jumping spider in the genus Aelurillus that lives in Namibia. It was first described in 2006 by Wanda Wesołowska. The species is medium-sized to large, with a dark brown carapace that is between 2.6 and 3.6 mm long and a fawn abdomen that is between 2.2 and 3.3 mm long. The spider has an indistinct marking of two brown streaks on the abdomen, which is nearly invisible on the female. It is unusual in the genus for the lack of central depression and sclerotized flaps at the top of the copulatory openings in the female epigyne. This, along with the shape of the male copulatory organs with their distinctive coiled embolus, enable the spider to be differentiated from others in the genus.

<i>Langona vitiosa</i> Species of spider

Langona vitiosa is a species of jumping spider in the genus Langona that lives in Namibia. The male was first described by Wanda Wesołowska in 2006. The female has not been identified. The spider is small with a dark brown carapace between 2.2 and 2.3 mm long and a brown-black abdomen between 1.8 and 1.9 mm. The spider has two white stripes on its carapace and a single white stripe on its abdomen, and the toothless chelicerae typical of the genus. The spider can be best distinguished by its copulatory organs, and particularly the existence of one small bump near to the sole appendage on the pedipalp tibia, which also lacks the setae that can be found on other species.

<i>Langona mediocris</i> Species of spider

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.

<i>Asemonea virgea</i> Species of spider

It is a small spider, with a carapace that is typically 1.16 mm (0.046 in) long and an abdomen typically 1.2 mm (0.047 in) long. The carapace is whitish-yellow with black markings and the abdomen black with whitish-yellow markings. The coloration, as well as the lip on its dorsal tibial apophysis, help distinguish the species from the otherwise similar Asemonea maculata, Asemonea minuta and Asemonea tanikawai. The female has not been described.

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.

<i>Asemonea murphyae</i> Species of spider

Asemonea murphyae is a species of jumping spider in the genus Asemonea that lives in Kenya and South Africa. First defined in 1980 by Fred Wanless, the spider is named after the British arachnologist Frances M. Murphy. Asemonea murphyae thrives in a wide range of environments, particularly by the side of rivers, streams and tracks. A small spider, with a carapace that is between 1.48 and 2.00 mm long and an abdomen between 2.4 mm long, it is generally yellow with a green tint that enables it to blend into its environment. The female is smaller than the male. The species can be distinguished from other spiders in the same genus by the design of the female's epigyne and the male pedipalp, particularly the male's forked spike on the palpal tibia.

<i>Asemonea stella</i> Species of spider

Asemonea stella is a species of jumping spider in the genus Asemonea that lives in Kenya, South Africa and Tanzania, and has been introduced to Australia. It thrives in a wide range of environments, from open farmland to semi-aquatic vegetation. The spider was first defined in 1980 by Fred Wanless. The spider is small, between 3.1 and 3.64 mm long, the female being generally larger than the male. It has a carapace that is pear-shaped and either yellow in the case of the male or green in the case of the female, measuring between 1.28 and 1.46 mm in length.The abdomen is whiter, between 1.28 and 1.46 mm long and has a distinctive star-shaped pattern on the back. Its copulatory organs help differentiate the species, particularly the furrow on the femoral apophysis of the male palpal bulb and the shallow depression in the middle of the female epigyne.
