V − K magnitude versus Li EW for original sample (blue) and targets identified in this work (red). Filled and open markers represent detections and non-detections, respectively. Black open circles represent sources classified as non-members (“N”) in Table 4. The black lines encompass regions of lithium depletion (Li/Li₀ ≤ 0.1) using the models of Baraffe et al. (2015). In the middle panel there are two minima corresponding to ages of 30 and 40 Myr.
