Genus Lophostica Simon, 1902  

Type species: Lophostica mauriciana Simon, 1902  

Description. The genus is distinctive in having chelicerae with a broad quadri-cuspid retromarginal tooth in both sexes. The embolus is accompanied by a free terminal apophysis, similar to that in the genus Rumburak   described below. The epigyne is similar to other Euophryinae   , with two oval depressions, short seminal ducts and bean-shaped spermathecae. The distance between the anterior lateral eyes is a little larger than between the posterior laterals in both sexes. Tibia I has four pairs of long ventral spines and metatarsus I has three pairs.

Redescription of the type species is given in Duhem, Ledoux & Wesołowska (2005).

Distribution. The genus only includes three species occurring on the Mascarene Archipelago.

Remark. Two species described by Ledoux (2007) from Reunion demand redescriptions; the form of their chelicerae and lack of free terminal apophysis suggests that they are misplaced (they are similar to some Euophrys   members).

Genus Rumburak   gen. nov.

Type species: Rumburak lateripunctatus Wesołowska, Azarkina & Russell-Smith  

Diagnosis. The genus is distinctive in the form of the embolus. The embolus forms a basal loop on the bulb apex, and extends towards the palpal tip together with a free terminal apophysis (the embolus appears to be composed of two branches). The presence of a free terminal apophysis sets this genus apart from all other Afrotropical Euophyrinae except Lophostica mauriciana Simon, 1902   from the Mascarene Islands, but the latter has a different cheliceral dentition (a wide retromarginal tooth with four cusps). Rumburak   shares some genitalic characters with this subfamily, e.g. an elongated bulb, the spermophore forming three meanders, and the presence of a basal embolic loop. The epigyne resembles those of other Euophryinae   genera in its form, with pits hiding the copulatory openings surrounded by sclerotized flanges, but the seminal ducts are relatively shorter than in the other genera.

Etymology. Name arbitrary; Rumburak   is the name of a bad wizard from a popular Czech film for children. Masculine in gender.

Composition. Seven species, of which six are described below as new.

Distribution. The genus is restricted to South Africa.
