Figure 94 in Phylogeny of the spider genus Ixchela Huber, 2000 (Araneae: Pholcidae) based on morphological and molecular evidence (CO1 and 16S), with a hypothesized diversification in the Pleistocene

Figure 94. Chronogram with the molecular dating for the genus Ixchela using the lognormal relaxed clock model. Bars at nodes indicate the 95% highest posterior density interval (HPD) to each tmrca (time of the most recent common ancestor). Numbers on bars indicate the mean age for each node in millions of years (Mya). Gradient of colours indicates ages of nodes, from the older nodes (darker) toward more recent nodes (lighter).
