Subfamily Masteriinae  Simon, 1889

Diagnosis. The subfamily Masteriinae  differs from the other subfamilies of Dipluridae  in the apical linear serrula ( Fig. 1AView FIGURE 1; Raven, 1991), the anterior median eyes are reduced or absent ( Fig. 3A –CView FIGURE 3; Raven, 1991); and the tarsal organ lacks elevation with low and concentric keels ( Fig. 1C –DView FIGURE 1). We also propose two new characters to enhance the diagnosis of the subfamily: the shape of the tarsal organ ( Fig. 1C –DView FIGURE 1), and trichobothria with corrugated bases and longitudinal keels ( Fig. 1EView FIGURE 1), which is not exclusive to Masteriinae  ; Barychelidae  and Theraphosidae  may have similar bases ( Guadanucci, 2012).
