Balleriolus , a new termitophilous genus of Ceratocanthinae (Coleoptera: Hybosoridae) from South America and notes on termitophily in the tribe Scarabatermitini

ABSTRACTBalleriolus, a new genus of Ceratocanthinae similar to Ivieolus Howden and Gill, 1998, is described and illustrated to include Balleriolus howdeni sp. n. from central Brazil and Balleriolus alleni sp. n. from Ucayali, Peru. It is proposed here that the tribe Ivieolini Howden and Gill, 2000 is a junior synonym of Scarabatermitini Nikolajev, 1999. Additionally, we define the Ivieolus genus group to include Balleriolus gen. n. and Ivieolus. A key to species of the group and a distribution map also are provided.http://www.zoobank.org/urn:lsid:zoobank.org:pub:8E242F36-9620-4F3A-9B15-858C8A7B0B6FKEYWORDS: NeotropicalphysogastryScarabaeoideasymphilic inquilinesstenogastry AcknowledgementsRS thanks Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) for financial support, and Dr Sônia Casari (MZSP) for helping with the illustrations.
