Etymology. The specific name is a patronyme in honour of Dr Ansie Dippenaar-Schoeman who promotes the arachnological science in Africa; noun in genitive case.

Diagnosis. Small-sized Eusparassus species. Male with diagnostic triangular ET and lobe of EM projecting behind base of conductor on tegulum ( Figs 31a, c View FIGURE 31 ). Epigyne and MS elongated ( Figs 32a View FIGURE 32 , 33a View FIGURE 33 ); vulva with humplike glandular process ( Figs 32c View FIGURE 32 , 33b View FIGURE 33 ) [see also diagnosis for jaegeri species group above].

Description. Male (ranges: n=3, single measurement: holotype):
