This paper reviews the status of Geodiapria and its nominotypical and only included species G. longiceps. Geodiapria was previously understood to be very similar to, and doubtfully separated from the genus Basalys. We use integrative taxonomy (morphology, DNA-barcoding, phylogenetic tree building) to show that the valid name for what was G. longice...
