Diagnosis. Ariadna boesenbergi  is similar to A. crassipalpa  , A. mollis  , A. calilegua  , A. changellkuk  , A. levii  and A. perkinsi  due to the dark abdominal pattern with arrow-shaped marks ( Figs 1A ‒CView FIGURE 1, 18A, FView FIGURE 18, 20A, FView FIGURE 20, 22A, FView FIGURE 22, 31A, EView FIGURE31, 45A, FView FIGURE 45, 47A, FView FIGURE 47, 50A, FView FIGURE 50), but differ, except A. changellkuk  , by the presence of males with metatarsi I straight, without modified macrosetae ( Fig. 22C ‒EView FIGURE 22); it differs from A. changellkuk  by having a less elongated body ( Fig. 22A ‒BView FIGURE 22) and a more elongated mid-portion and embolus ( Fig. 23A ‒BView FIGURE 23); females are distinguished by the presence of a unillobulated anterior receptaculum, flattened laterally ( Fig. 23C ‒DView FIGURE 23).
