The monophyly of Theridiidae receives strong support in this study. Unambiguous synapomorphies on this cladogram include: male palpal tibia distally broadened ( 14, Fig. 4E View Figure 4 ), paracymbium lost ( 29, Fig. 92A- M View Figure 92 ), bulb-cymbium lock mechanism ( 31, Fig. 31F View Figure 31 ), alveolus flush on mesial cymbial margin ( 41, Fig. 92D–I, M View Figure 92 ), MA containing loop of sperm duct ( 72, Figs 90F View Figure 90 , 91A View Figure 91 ), MA, tegulum membrane ( 73), a distal hood on MA ( 78, Fig. 31F View Figure 31 ), retromarginal cheliceral teeth lost ( 110, Fig. 5F View Figure 5 , several reversals), abdominal suprapedicellate apodemes weakly sclerotized and fairly smooth ( 165, Figs 4F View Figure 4 , 63H View Figure 63 , 82E, F View Figure 82 ), highly flattened anterior PLS AG spigots ( 215, Figs 11B View Figure 11 , 78B View Figure 78 ), PMS mAP nubbins lost ( 220, Figs 18F, G View Figure 18 , 25C, D View Figure 25 ), exactly two PMS AC spigots ( 222, Fig. 18G View Figure 18 ). Notable ambiguous synapomorphies are a nonrebordered labium ( 134, Fig. 5A View Figure 5 , DELTRAN, also in Synotaxus ), and highly flattened posterior PLS AG spigots ( 216, ACCTRAN, not in Dipoena ).
