Genus Hyllus
The genus Hyllus C. L. Koch, 1846 contains more than 50 species in Africa and several ones in other continents.
Distinguishing members of Hyllus and Evarcha is problematic. Many species in both genera have “horns” formed by tufts of long bristles located at posterior median eyes. Hyllus includes medium-sized to large spiders with rounded carapace, clearly wider than eye field, whereas members of Evarcha are usually smaller and their carapace is not as wide. Male pedipalp in Hyllus has generally long embolus, often with accompanying pars pendula, whereas the majority of Evarcha species have short embolus, sometimes with compound terminal apophysis epigyne in Evarcha has two pockets near epigastric furrow, which are not present in Hyllus, additionally the epigyne in the latter genus is more sclerotized.

Salticidae, Genus Myrmarachne
Genus Myrmarachne
Myrmarachne is a genus of jumping spiders which imitate an ant by waving their front legs in the air to simulate antennae. Some species also look strikingly like ants. Spiders in this genus are commonly called antmimicking spiders, although there are many other spiders that mimic ants. Their resemblance to ants appear to function primarily as Batesian mimicry. Many predators avoid eating ants, so their resemblance to these insects protects them from predators.
The cephalothorax is elongated, with long chelicerae projecting forward in males. A waist is present on the cephalothorax, and often also on the opisthosoma. Colors vary from black to yellow, depending on the mimicked ant species. One African species was observed to mimick one species when immature, and another as an adult.
Several species (17 or more) are recorded from South Africa:
Myrmarachne albosetosa
Myrmarachne dundoensis
Myrmarachne foenisex
Myrmarachne foreli
Myrmarachne ichneumon
Myrmarachne inflatipalpis
Myrmarachne laurentina
Myrmarachne leleupi
Myrmarachne lesserti
Myrmarachne lulengana
Myrmarachne marshalli
Myrmarachne natalica
Myrmarachne solitaria

Salticidae, Genus Nigorella
Genus Nigorella
The genus Nigorella is a small Afrotropical genus, only containing four poorly known species. Nigorella hirsuta is recorded from Zimbabwe and South Africa.
Nigorella manica occurs in Zimbabwe.
These spiders are medium to large in size, with dark colouration; the males have a characteristic embolus enveloped by a terminal apophysis; the gonopores in the female’s epigyne are hidden in strongly sclerotized “cups”.

Salticidae, Genus Thyene
Genus Thyene
This genus Thyene includes over 40 species, the majority of them being distributed in the Afrotropical Region.
Members of Thyene are characterized by the presence of tufts of long black hairs near the posterior median eyes. The genital organs are very similar; the male palp has a rounded bulb and embolus encircling it few times; the epigyne is very weakly sclerotized, with a central window, seminal ducts forming a few loops, and very long accessory glands. Thyene species may be more easily distinguished by their colouration than by genitalic structures.
