Mexcala synagelese is a species of jumping spider in the genus Mexcala that lives in Angola, Democratic Republic of the Congo, Ivory Coast, Nigeria and Sudan. The spider was first defined in 2009 by Wanda Wesołowska, one of over 500 that the arachnologist described during her career. It mimics ants and ant-like wasps, living alongside and preying upon them. The spider is medium-sized, with a dark brown carapace between 2.7 and 3.2 mm long and a pale brown to dark brown abdomen between 3.2 and 4.0 mm long. The male has three strips on its abdomen while the female has a more complex pattern of dark bands and light patches. The spider has long thin brown legs. It has good eyesight, which it uses when hunting and also during courtship. The male palpal bulb has a long tibial apophysis, or spike, that curves in towards the bulb. The female epigyne has two shallow depressions and short seminal ducts that lead to long receptacles.
Mexcala torquata is a species of jumping spider in the genus Mexcala that lives in Guinea and Ivory Coast. It 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 dark brown carapace that is between 3.0 and 3.3 mm long and a brown abdomen between 3.0 and 3.7 mm long. It has long thin legs and serrated chelicerae. Similar to other species in the genus, it mimics ants and ant-like wasps, living alongside and preying upon them. The female has a distinctive fillet on the back of its abdomen, after which the species is named. However, it can be most easily distinguished from other spiders in the genus by its relatively small copulatory organs, specifically its very small epigyne, seminal ducts and embolus.
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.
Cembalea triloris is a species of jumping spider in the genus Cembalea that lives in Namibia and South Africa. It was first described in 2011 by Wanda Wesołowska and Charles Haddad. The spider gets its name from the existence of three distinctive white stripes on its back, more noticeable on the male. The spider is small, with a dark brown carapace that is between 2 and 2.3 mm long and a lighter sandy or yellowish-white abdomen that is between 2.4 and 2.6 mm long. It has a large eye field and a clypeus that extends to the edge of the carapace. It can also be distinguished from other members of the genus by the large spike that protrudes from the abdomen and the male's long embolus.
Manzuma jocquei is a species of jumping spider in the genus Manzuma that lives in Central African Republic, Ivory Coast and Nigeria. Originally named Aelurillus jocquei, the spider was first described in 2011 by Wesołowska and Antony Russell-Smith. The spider is small, with a carapace between 1.5 and 2.1 mm long and an abdomen between 1.3 and 2.3 mm long. The carapace has a white stripe formed of scales which is more pronounced on the male. The male abdomen also has a stripe, but the female has two lines of white spots. The male has a thin embolus that is hidden by the hairy palpal bulb while the female has complex highly sclerotized copulatory ducts and a large pocket in the epigyne. These distinguish the species from other spiders in the genus, although the females are almost impossible to tell apart from some species like Manzuma lympha and Manzuma nigritibia.
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.
