About me

Maryzender

I am a zoologist and evolutionary biologist currently undertaking a PhD at the Universidad Nacional de La Plata (Argentina), with research based at the Laboratory of Entomology of Argentine Dryland Research Institute (IADIZA, CCT CONICET Mendoza).

My research centres on the systematics and taxonomy of Neotropical and Andean rove-beetles (Coleoptera: Staphylinidae), integrating field trips, morphology, molecular biology, and phylogenetic analysis to investigate their evolutionary relationships and species diversity.

Ongoing projects

The systematics of Neotropical and Andean rove-beetles

The evolution of the myrmecophily and termitophily in the Neotropical Philonthina rove-beetles, which is the focus of my PhD thesis

Philonthina rove-beetle
