Fossils described in Trichadenotecnum and Psocidus (F1 evidence) may represent a substantial gap between the time of the cladogenetic
events and their recovery.
Another option would be a process of cladogenetic
speciation along the Early Pliocene, resulting in two different lineages of Debruijnimys, and unnamed species and D.
Wright & Stigall (2013a) divided cladogenetic
events in these taxa into two temporal bins.
Phylogeographic approaches reinforce the hypothesis that the area of cladogenetic
event was the central-western region of the country (La Rioja and Catamarca provinces) (Martinez et al.
Indeed, a strong phylogeographic pattern has been observed and the temporal sequence of cladogenetic
events is in good agreement with the geographic distribution of Dolichopoda studied; this supports the inference that speciation events are strictly allopatric and mostly determined by isolation of different populations in isolated cave systems (Allegrucci et al.
