Phylogenetic analysis of Blaberoidea reveals non‐monophyly of taxa and supports the creation of multiple new subfamilies [PDF]

open access: yesCladistics, Volume 39, Issue 3, Page 198-214, June 2023., 2023
Abstract The superfamily Blaberoidea is a highly species‐rich group of cockroaches. High‐level blaberoidean phylogenetics are still under debate owing to variable taxon sampling and incongruence between mitochondrial and nuclear evolution, as well as different methods used in various phylogenetic studies.

Unravelling the species diversity, phylogeny and biogeography of the mycoheterotrophic Voyrieae (Gentianaceae) and the description of a new species

open access: yesTAXON, Volume 71, Issue 5, Page 1013-1024, October 2022., 2022
Abstract Because different tropical forest regions possess their own species diversity and communities, it is crucial to investigate the diversification history of their biota to understand how biodiversity was assembled. However, this requires reliable species concepts and robust, well‐sampled phylogenies.
