Eburneana is a genus of the spider family Salticidae (jumping spiders).
Like several other salticids, this genus mimicks ants.
Eburneana are rather big ant-like spiders with a constricted cephalothorax. They are 8 to 12 mm (0.31 to 0.47 in) long. The body is very flat and rather slender. The cephalic and thoracic parts are parted by a clear constriction to mimic the ant body plan. Unlike other African ant-like salticids Eburneana has the chelicerae located more posteriorly, rich leg spination and clearly visible large spigots on the posterior spinnerets.
The structure of genitalia and the shape of the first legs resembles males of the subfamily Pelleninae, but the phylogenetic relationships of Eburneana to other genera are unclear.
The genus is named after the Latin name of Ivory Coast, Litus Eburneum, where one of the species was first found.
Wanda Wesołowska is a Polish zoologist known for her work with jumping spiders. She has described more species of jumping spider than any contemporary writer, and is second only to Eugène Simon in the history of arachnology. Originally a student of ornithology, she developed an interest in jumping spiders while still a student at the Siedlce University of Natural Sciences and Humanities in the 1970s.
Mexcala angolensis is a species of jumping spider in the genus Mexcala that is endemic to Angola, after which it is named. The spider was first defined in 2009 by Wanda Wesołowska, one of over 500 that the arachnologist described during her career. The spider is medium-sized, with a brownish carapace typically 3.4 mm (0.13 in) long and a light brown abdomen typically 3.0 mm (0.12 in) long that has an indistinct dark streak that runs down the middle. It mimics ants and ant-like wasps, living alongside and preying upon them. The male can be distinguished from other Mexcala species by the small teeth at the end of its tibial apophysis, or spike, and the lack of a bump on its palpal bulb. The female has not been described.

Eburneana wandae is a species of jumping spider in the genus Eburneana that mimics ants. It was named by Tamás Szűts after the Polish arachnologist Wanda Wesołowska. The male of the species was first described in 2003, with the holotype found in the forests of central Africa. It is a relatively large spider, 8.2 millimetres (0.32 in) long, and is distinguished from the similar Eburneana scharffi by its different geography, being found in Cameroon rather than Tanzania, and the shape of the spider's front legs.
Eburneana scharffi is a species of jumping spider in the genus Eburneana that mimics ants. Found in Tanzania, the spider was first described in 2001. It is a large spider, particularly the male, with a carapace that is between 3.9 and 4.6 millimetres long, and shares features to both species in its own genus and those in the family Pelleninae. The female has a distinctive pattern on its abdomen formed by white hairs. It is the type species of the genus.
Eburneana magna is a species of jumping spider in the genus Eburneana that mimics ants. It is a large spider, as is emphasised by the species name, the Latin for big, with a body that can be up to 12 millimetres (0.47 in) in length, although only the female has been identified and in other species in the genus the male is larger than the female. The species has been identified from a holotype found in Ivory Coast.
Mexcala smaragdina is a species of jumping spider in the genus Mexcala that is endemic to Nigeria. The spider was first defined in 2012 by Wanda Wesołowska and G. B. Edwards. Spiders of the genus mimic ants and ant-like wasps, living alongside and preying upon them. The spider is medium-sized, with a cephalothorax typically 2.5 mm (0.098 in) long and an abdomen 2.7 mm (0.11 in) long. The male has a hooked embolus that is shorter than the related Mexcala caerulea but otherwise the male copulatory organs are similar. The female has not been identified. The spider is most easily distinguished by the green-metallic sheen on its body, which is referred to in the species name.
Mexcala macilenta is a species of jumping spider in the genus Mexcala that lives in Ethiopia and Tanzania. The spider was first defined in 2000 by Wanda Wesołowska and Anthony Russell-Smith. It mimics ants and ant-like wasps, living alongside and preying upon them. The spider is medium-sized to large, with a brown carapace between 3.2 and 3.4 mm long and a rusty-brown or greyish-russet abdomen between 3.2 and 5.5 mm long. The female is larger than the male. Both male and females have long thin brown legs and a distinctive pattern of a large triangular black marking in the middle of the abdomen. The male copulatory organs have a thin tibial apophysis and lack the triangular lobe on the palpal bulb that other species in the genus possess.
Mexcala monstrata is a species of jumping spider in the genus Mexcala that lives in Egypt and Yemen. The spider was first defined in 1994 by Wanda Wesołowska and Anthony Van Harten. It mimics ants, living alongside and preying upon them. It is a medium-sized spider, with a dark brown carapace that range between 2.8 and 3.6 mm long and an orange abdomen between 3.0 and 5.8 mm long. The female is larger than the male. Juveniles have also been found that have a carapace that measures between 2.46 and 2.82 mm in length and an abdomen that is between 2.13 and 2.4 mm in length. The abdomen in all cases has a dark stripe across the middle, although the male's is thinner. The spider is similar to the related Mexcala agilis and Mexcala elegans, but can be distinguished by the wider tibial apophysis on the male palpal bulb and the presence of two heavily sclerotised shallow depressions in the female epigyne.
Bacelarella gibbosa is a species of jumping spider in the genus Bacelarella that is endemic to Nigeria. The spider has a distinctive shape to the carapace that gives the species its name, which can be translated hunchback. It was first described in 2012 by Wanda Wesołowska and Glavis Edwards. The spider is medium-sized with a cephalothorax that has a length between 3.1 and 3.8 mm and an abdomen that is between 2.6 and 3.4 mm long. The female is larger than the male. It is also generally lighter in colour, the male having a darker brown carapace, clypeus and legs. The species can be distinguished from others in the species by the male's round small palpal bulb and long thin embolus and the larger pocket in the female's epigyne.
Bacelarella dracula is a species of jumping spider in the genus Bacelarella that lives in Ivory Coast and Nigeria. It was first described in 2001 by Tamás Szűts and Rudy Jocqué based on a holotype found near Appouasso. The spider is medium-sized with a plain dark brown carapace that has a length between 2.3 and 3.0 mm and a mottled abdomen that is between 2.3 and 2.8 mm long. The female is larger than the male. The male has a prominent tooth, which gives the species its name, recalling the fictional Count Dracula. The male also has a distinctive long prong that extends from the palpal bulb and a long embolus that curves so far that it nearly ends at its start. The female can be distinguished by its epigyne, and particularly the tight coil at the end of the copulatory openings.
