Material examined.

ARGENTINA. Falklands (Islas Malvinas), 1 ♂ (SMF 1320/8).

Description.

Penis (Fig. 18 A–B; SMF 1320/8): ventral plate with lateral margins slightly concave, distal margin straight, 3 distal pairs of cylindrical, straight, long setae, 1 pair of median short setae, 2 pairs of basal cylindrical, straight, long setae. Glans sac projected dorsally, ventral process and stylus arising ventrally. Stylus long, slightly curved, with apical ventral and lateral trichomes. Ventral process swollen apically, with nailhead-like apex.

Taxonomical note.

The examination of detailed photos of Gonyleptes defensus type material and subsequent comparison of those with the description of Sadocus vallentini allowed recognizing them as conspecific.
