We describe a new genus and species of Paederinae rove beetles, Ruptor cordatus gen. et sp. nov., which lives in the arboreal nests of the termite Labiotermes labralis (Holmgren, 1906) in the Amazon lowlands of Peru. The morphology of Ruptor gen. nov. is highly derived, apparently due to its close association with the termite host, and thus, morphologically, the genus cannot be classified further than Lathrobiini incertae sedis. In order to address the sister-group relationships of Ruptor gen. nov., we conducted a molecular phylogenetic analysis based on seven gene fragments. The analysis indeed resolved the genus as a member of the tribe Lathrobiini and placed it nested within the informal clade of ‘Medonina and allied taxa’. We provide a morphological comparison of the new genus with all known myrmeco- and termitophilous representatives of the subfamily, and to the extent possible, we illustrate other relevant and poorly known Neotropical Paederinae inquilines.
