EXAMINED. Diagnosis: Males are distinguished from all Agyneta species by their long, sinuous and narrow lamella characteristica with blunt tip (Fig. 137). Females are distinguished from most Agyneta by their deep pit hook depression (Fig. 141). From closely related species by the slightly oblique sides of the proximal part of scape (Fig. 141), strongly oblique in A. nigripes (Fig. 127) and straight A. rurestris, A. jacksoni and A. maritima (Figs 112, 120, 134).
