Etymology. The species is named in honour of Dr Peter Jäger (SMF) in recognition of his scientific support of this project and also his invaluable help, motivation and encouragement; noun in genitive.

Diagnosis. Males differing from congeners by slender and curving ET pointing smoothly distad at its distal end ( Fig. 29c View FIGURE 29 ) and dRTA with a ventral bulge ( Figs 29a, b View FIGURE 29 ); epigyne with two large triangular processes at posterior margine of lateral lobes (LL) ( Fig. 30a View FIGURE 30 ) [see also diagnosis for jaegeri species group above].

Description. Male (ranges: n=8, single measurement: holotype):

Measurements. Males medium sized; total length 13.5, prosoma length 5.7–6.3, prosoma width 4.7–5.8, anterior width of prosoma 2.5–3.1, opisthosoma length 7.8–8.0, opisthosoma width 4.0–4.7.
