Divergence time estimates
A chronogram for Typhlocybinae divergence dates and topologies based on
whole mitochondrial protein coding genes is shown in Figure 5. According
to this result, Typhlocybinae arose ~118 million years
ago (MYA)
(94–142
MYA 95% HPD), during the middle Cretaceous period. Divergence of major
lineages within Typhlocybinae was estimated to have begun
~99 MYA (78–119 MYA 95% HPD) with all tribes having
first appeared during the Late Cretaceous. These date estimates are
slightly younger than, but within the 95% confidence intervals, of
those reported by Dietrich et al. (2017).
