Twenty-two new species of Panabachia Park (Coleoptera: Staphylinidae: Pselaphinae: Brachyglutini: Brachyglutina), are described from montane forest and páramo habitats of Ecuador: Panabachia pahuma sp. nov. , P. trifecta sp. nov. , P. inornata sp. nov. , P. amica sp. nov. , P. winku sp. nov. , P. ayauma sp. nov. , P. pastazae sp. nov. , P. romeroi sp. nov. , P. uktu sp. nov. , P. salebrosa sp. nov. , P. urbana sp. nov. , P. carltoni sp. nov. , P. falini sp. nov. , P. papallacta sp. nov. , P. ananay sp. nov. , P. cayambi sp. nov. , P. cryptica sp. nov. , P. caranqui sp. nov. , P. patera sp. nov. , P. vigilans sp. nov. , P. perdita sp. nov. , and P. ambulans sp. nov. Only two species of the genus have been previously described, from Panamanian and Guatemalan lowlands. But, based on unpublished records, the genus is now known to occur from Mexico to Bolivia, and includes several additional undescribed species. These new species exhibit important variability in the diversity in male secondary sexual characters. Images of the habitus, key characters and aedeagus are provided for the new species.
