Going silent? Evidence for independent losses of acoustic communication in tree crickets (Insecta, Orthoptera, Grylloidea, Oecanthidae)

Journal of Systematics and Evolution, EarlyView.
Our ancestral state reconstruction in tree crickets reveals multiple independent and irreversible losses of sound‐producing and ‐receiving structures, supporting the convergent evolution of the silent phenotype. We demonstrate strong evolutionary integration between forewings and tympana, although the discovery of ‘silent listeners′ and ‘deaf singers ...

Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

Journal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.
