Diagnosis.

Males of this species are recognised by the cymbium without retrobasal button like process (Fig. 12 C View Figure 12 ), by the dorsal prong of palpal tibial apophysis parallel-sided up to distal tip (Figs 12 C View Figure 12 , 13 B View Figure 13 ) and by the well-developed tegular subdistal tooth visible from both sides (Fig. 13 A, B View Figure 13 ). Females are characterised by the epigyne scape with parallel sides, indented at posterior tip and reaching 0.75 of epigyne length.

Description.

For description, see Jocqué (1991: 41).

Distribution.

Known from areas across the African continent, from Ethiopia in the east, to Guinea in the west (Fig. 24 View Figure 24 ).
